Changelog 7.1

Several fixes to work with current browser versions
Removed SeaMonkey special handling for preferences dialog
Removed obsolete buttons (Back, Forward, Stop, Reload, Save Page)
Fixed "Clear History" for current Firefox releases

Changelog 7.0

Replaced "eval" with "evalInSandbox" to execute code inside PrefBar buttons. This change was required to get code review from the addons.mozilla.org team. I've bumped the version to 7.0 as this is a major change which may break some buttons. Please report any errors, you find. (Manuel Reimer)
Improved support for legacy platforms which don't have the required message manager features, which are only available on browsers that are e10s capable. (Manuel Reimer)
Some more e10s fixes. Button import now works again. Please report any problems you still find with e10s. (Manuel Reimer)

Changelog 6.6

Initial support for "Electrolysis" using a new function type "Framescript" which can run in the content processes (Manuel Reimer)
Fixed button import for Firefox version 36 and above (Manuel Reimer)
Fixed bug 26006 "'Colors' checkbox no longer works" (Manuel Reimer)

Changelog 6.5

Text labels are now vertically centered on toolbar. (Manuel Reimer, suggested by Yves Goergen)
Removed hack for visualizing unchecked checkboxes in menus (toggling between "checkbox" and "radio" type of menuitem). The default behaviour is now the operating system default. If you want to have a better distinction between "button" and unchecked "checkbox/extcheck" items, give the new "Visualize unchecked checkboxes in menus" checkbox in the "Options" pane of the PrefBar configuration window a try. (Manuel Reimer)
Added warning message if you import BTN files in the old "RDF based" format. It is recommended to re-export such files to migrate them to the new "JSON based" format as used by PrefBar since version 6.0. (Manuel Reimer)
Fixed "Clear Cache" for Firefox 32 (Manuel Reimer, reported by rold5 via MozillaZine forum)

Changelog 6.4

In resize menulist, it is now possible to omit one of the values to, for example, only set the width of the window. (dickvl from mozillaZine forum)
Many improvements for the new Firefox 29 (Australis) interface (Manuel Reimer)

Changelog 6.3

Added support for Favicons in the "link" buttons on PrefBar (Manuel Reimer, suggested by Daniel Middleman)
Initial support for the "Australis" theme (Manuel Reimer)
Fixed a compatibility problem with "Clear Downloads" button on Firefox 26 (Manuel Reimer)
Help system updated (Manuel Reimer)
Replaced all occurrences of "Preferences Toolbar" with just "PrefBar". I don't want to advertise PrefBar to be a "toolbar" (separate bar in your browser) anymore, as this is just wrong with current PrefBar versions. You can use the "PrefBar menu" button or you can move the PrefBar button group to other toolbars. No need to use PrefBar's own toolbar! (Manuel Reimer)

Changelog 6.2.2

Fixed Bug 25532 "Flash Enable/Disable Checkbox not working in Firefox 23" (Manuel Reimer)

Changelog 6.2.1

Fixed "prefbarClearDownloads" for Firefox 8.0/SeaMonkey 2.5 and above. This function can be used as part of a copied version of the "Clear All" button. (Manuel Reimer, reported by Juergen Ringschmidt)
Fixed Bug 25397 "<clrhist> button no longer works" (Manuel Reimer)
Now all PrefBar windows should have the PrefBar logo in the title bar (Manuel Reimer)

Changelog 6.2

The PrefBar context menu now contains an "Edit button" entry, which allows to edit buttons without going over "Customize PrefBar". (Manuel Reimer, inspired by the AMO review from "herbalist")
The Proxy Serverlist now supports IPv6 addresses, if they are enclosed in square brackets. (Manuel Reimer, suggested by "Tom" on the support newsgroup)
The Button editor now contains an "Apply" button to save changes without leaving the dialog. (Manuel Reimer)
It is now possible to jump to source view from error console, if your button caused an exception. (Manuel Reimer)
You no longer have to set an ID for "spacer" or "separator" items. If you click on "New" -> "Spacer"/"Separator", then the item is created immediately using an anonymous unique ID. (Manuel Reimer)
"about:config" integration, which allows you to enter the button editor directly from the about:config context menu. (Manuel Reimer)
In SeaMonkey >= 2.1, the "Restore Tab" button now restores more than three tabs, again. (Manuel Reimer)
Replaced image in page header of help pages with CSS-styled text. This makes PrefBar overall size a bit smaller and allows to translate the page header easily. (Manuel Reimer)
Added PrefBar's own context menu for the PrefBar menu button. (Manuel Reimer, suggested by Sascha Grage on usenet)
Fixed Bug 24972 "UA reset may conflict with session restore" (Manuel Reimer)
Fixed Bug 25180 ""Save" no longer works" (Manuel Reimer)

Changelog 6.1

Japanese translation (Norah Marinkovic)
The "language list" now is an editable list, allowing you to enter/edit your preferred languages directly in the PrefBar GUI. (Manuel Reimer)
Updated user agent strings to contain some "newer ones". This only affects new installations, as the user agent list is excluded from update! (Manuel Reimer)
Dropped the "execute demo" buttons. They will be replaced with a "Create buttons that run external programs" tutorial on the PrefBar homepage, at some time (Manuel Reimer)
Modified help system to use "DTD" files and entities for translation (Manuel Reimer)
Removed separate cache buttons for "memory cache" and "disk cache". Most users aren't interested in how cache is handled in backend. They just want to enable, disable or clear the browser cache. As there was no generic "Cache" checkbox, to "just enable/disable cache", I created one. (Manuel Reimer)
Fixed Bug 23412 "Drag&Drop of button onto itself moves it to the top of the list" (Manuel Reimer)
Fixed bug that caused button translations, defined in locale, to not always take affect (Manuel Reimer)

Changelog 6.0.1

Implemented whitelist for websites, allowed to import buttons. This whitelist is editable in the PrefBar configuration dialog and is presetted with one allowed websites, which is the PrefBar project page (prefbar.tuxfamily.org). (Manuel Reimer)
Fixed Bug 24212 "PREFBAR.JSON doesn't store Unicode data" (Manuel Reimer)
Fixed Bug 24240 "No "event" passed to button code, when executed via hotkey" (Manuel Reimer)

Changelog 6.0

Changed button datasource format from RDF to JSON. PrefBar now saves button configuration to a file "prefbar.json" in your profile. Exported buttons are also JSON files, now. Older PrefBar versions won't be able to read buttons, exported from PrefBar 6.0! This change was required as the Firefox developers are also reducing their usage of RDF. This means, that there is a good chance, that we will have bugs in RDF, in future, which won't be fixed with priority (Manuel Reimer).
prefbar:// URLs now support SHA1 and SHA256 checksums to be integrated into the URL. I'll use this in future to make import from the "More buttons" page even more secure. (Manuel Reimer)
New value for resetting a pref from a menulist is now "!RESET!" (was: "PREFBARDEFAULT"). (Manuel Reimer)
"Slimbuttons" now is the default behaviour (makes buttons on PrefBar take less space). If you had disabled the feature, it is activated after this update and you have to disable it manually if you have any issues with it. (Manuel Reimer)
Got rid of some warnings in error console about octal literals and octal escape sequences being deprecated. (Manuel Reimer)
Added "Get more buttons" link to preferences window (Manuel Reimer)
Fixed Bug 23378 "Doubleclick on scrollbar in PrefBar edit window triggers "edit button"" (Manuel Reimer)
Fixed Bug 23398 "PrefBar adds unneccessary "browserbtnupdatefor="false"" to extchecks/extlists in btn files" (Manuel Reimer)
Fixed Bug 23399 ""ID" field should be pre-focused in "New Item" dialog" (Manuel Reimer)
Fixed Bug 23418 "Importing btn file without accepting to overwrite buttons causes PrefBar toolbar to not be re-rendered" (Manuel Reimer)
Fixed Bug 23711 "Can't add a new item if there are no Enabled Items" (Manuel Reimer)
Fixed Bug 24065 ""PrefBar Toolbar" Appears Twice in [View > Show/Hide] (Manuel Reimer)
Fixed Bug 24096 "Not available for SeaMonkey 2.1" (Manuel Reimer)

Changelog 5.1.1

Fixed Bug 22825 "IcedTea plugin for Java not detected" (Michael Buckley)
Fixed Bug 22918 "Chevron shown even when space on toolbar is sufficient" (dickvl)
Moved all skin related stuff to a dedicated "skin" area and added new icon files for the different button icon sizes. This fixes some smaller bugs with Firefox nightlies (Manuel Reimer)
Bumped minimal required Firefox version to 3.5, as my upgrade to the new drag&drop API makes PrefBar incompatible with older releases (Manuel Reimer)
Small fix to make "About PrefBar" window work in latest Firefox nightlies (Manuel Reimer)
Modified PrefBar's XPCOM component according to latest changes in XPCOM (Manuel Reimer)
Added file format check to button import (Manuel Reimer)

Changelog 5.1

Fixed Bug 22582 "Prefbar shows Java as activated while it is not" (Manuel Reimer)
Fixed Bug 22482 "Cannot Overwrite Button with New Version" (Manuel Reimer)
Fixed Bug 22394 "Execute buttons do not work correctly" (Manuel Reimer)
Fixed Bug 22088 ""clearall" not really clearing everything at all" (Manuel Reimer)
Fixed Bug 22383 "Regression in Prefbar 5.0.1: code in userChrome.css with negative margin values to make the toolbar as slim as possible no longer calculate the toolbar width correctly and leave white space at the right" (Manuel Reimer)
Fixed some smaller bugs in drag&drop code of customize pane, which possibly could have caused a drag&drop operation to fail (Manuel Reimer)
Fixed bug, which slowed down the customize process of PrefBar by triggering resize events, while moving buttons (Manuel Reimer)
Added small fix to make PrefBar work in Firefox 3.0.x, again. (Manuel Reimer)
Documented new way to move buttons to other toolbars in "Using Preferences Toolbar" section of this help system (Manuel Reimer)
Optimized speed of all RDF operations (Manuel Reimer)
Added "Copy button" feature. Just right click on a button entry in the customize pane and choose "Copy" (Manuel Reimer)
Added hack to work around a bug in SeaMonkey 2.0.x, which caused PrefBar to be cut off at the right end, on Windows systems (Manuel Reimer)
PrefBar now places its stuff to its own namespace and not longer pollutes global namespace (required to be accepted on addons.mozilla.org) (Manuel Reimer)
PrefBar menu moved from menubar to toolbar palette. This allows you to move the menu as button to any place, you like, on any toolbar. (Manuel Reimer)
Now it's possible to disable the "prefbar://" pseudo URL, if you don't want this for security reasons, in the "Options" preferences pane. (Manuel Reimer)

Changelog 5.0.1

Fixed Bug 22344 "PrefBar Extends Toolbars Beyond Right Edge of Browser Window" (Manuel Reimer)

Changelog 5.0

Dropped SeaMonkey 1.x support and dropped many lines of old code, only needed to keep compatible with SM 1.x. PrefBar needs at least SeaMonkey 2.0, now. (Manuel Reimer)
Separated PrefBar in a "customizable toolbar" and a "toolbaritem" placed on the browser's "toolbarpalette". This change allows the PrefBar buttons to be moved to other SeaMonkey/Firefox toolbars (as group, just like the bookmark toolbar items) and to move foreign buttons onto the PrefBar toolbar, using the Browser-built-in toolbar customize feature (Manuel Reimer)
Dropped PrefBar's own OSD message handling and replaced with support for the browser notification bar (Manuel Reimer)
Dropped old "toggle Flash" code. From now on, only the Plugin manager, built into the browser, is used for the Flash checkbox. If you port from SM 1.x to 2.x and had disabled Flash, then search your system for a file with the suffix ".prefbar" and drop this suffix or just reinstall Flash, so the browser finds it, again. (Manuel Reimer)
Made configuration window for Firefox look more "Firefox like" (Manuel Reimer)
Dropped two link buttons (xulplanet and mozillanews) and added one new link button to link to the PrefBar homepage (Manuel Reimer)

- context menu added
- items can be edited via doubleclick
- items may be moved between/in lists via drag&drop
Added several smaller fixes for SeaMonkey 2.0 (Manuel Reimer)
Separated the plugin toggle stuff to two simple functions, as newer Firefox releases will require me to also use this code to toggle Java (Manuel Reimer)

Changelog 4.2

Added possibility to add SOCKS proxies to Proxylist. More info here(Manuel Reimer)
Fixed Bug 20872 "Prefbar 4.1.1 messes up minimum window width" (Manuel Reimer)

The Flash checkbox now uses the builtin plugin manager, if running on SeaMonkey 2.x or Firefox 3.x, to toggle flash without the need to rename the plugin. (Manuel Reimer)
Now the "onClick" handler of buttons also gets called for middle clicks on buttons, to have another way to create "multifunctional" buttons. Have a look at "event.button", to find out which button has been used (Manuel Reimer)
Fixed Bug 19143 "PrefBar fails to initialize if SeaMonkey quickstart mode is used" (Manuel Reimer)
Fixed Bug 19142 "PrefBar update notifier doesn't stop on failed connections" (Manuel Reimer)

If you moved PrefBar to anywhere else than its own toolbar and you open a popup window, where this target is hidden, then PrefBar will fall back to "own toolbar" for this popup window to be visible, again (Manuel Reimer)
Improved error handling for code in buttons. One button with an bug in its code now not longer kills all buttons. Also improved error display in javascript console, which now displays more useful error messages for PrefBar button code (Manuel Reimer)
As the improved error handling now displays proper line numbers in the javascript console, I've added a "jump to line" feature to the context menu of any button code editor (Manuel Reimer)
Added update notifier. If the next version of PrefBar gets available, PrefBar will tell you. (Manuel Reimer)

New Toolbar Buttons. There are a whole bunch of new toolbar buttons in the prefbar2 that weren't avaiable in previous versions. This includes the new user agent menulist, navigation buttons, developer buttons, and several new pref checks. See the Button List for more information. (Aaron Anderson)
Customizable Toolbar. The toolbar is now completely customizable, with not only the ability to show only the buttons that you want, but the ability to display the buttons in any order you want, and even edit existing buttons or add new ones. Click the customize button on your toolbar to access the PrefBar customization panel, or find it in the "Advanced" catagory of the main preferences window. (Aaron Andersen)
Shortcut Key. You can now quickly show or hide the Preferences Toolbar whenever you need to by pressing the F8 key. I was told that mac users would flame me for stealing one of their F keys, so I hope that doesn't happen. (Aaron Anderson)
Documentation. I actually took the time to write a full featured documentation set for the PrefBar this time around (part of which you are currently viewing.) This should make it a lot easier to use the PrefBar than previous versions, in which users pretty much had to figure everything out on their own. (Aaron Anderson)
License. The original Preferences Toolbar was licensed under the "assume it's MPL unless told otherwise" license that is quite common among small XUL applications. The Preferences Toolbar 2 is now officially MPL/GPL/LGPL tri-licensed, including that huge bandwidth wasting license block at the first of every file. Feel free to rejoice now. (Aaron Anderson)
