Be careful with old versions!
These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.
*** Note that this is the last version supporting Firefox 16 and older; the *next* version will drop support for Firefox 16 and down, while keeping support for Firefox 17 and up.
Note for Firefox ESR 10 users: this is the last version compatible with ESR 10, and it's the one you want to use.
This will be the last version to support Firefox 3.6. The next official release will support Firefox 4 and up.
+ For people using Fx12 nightlies, restores main browsertab styling (-moz-border-image syntax change).
+ For Fx10, adds support for the updated Firefox Sync setup UI, including the new about:sync-progress page.
+ Adds support for add-on Firebug version 1.8. Keeps support for version 1.7, and drops support for version 1.6.
+ Updates styling for add-on Sage on the Mac.
+ Fixes unwanted white-yellow line above tabbox (such as the Firefox Preferences window) on OSX. Firefox on OSX (beginning around version 8 or so) has a problem where the 1x1 single-pixel background image used there isn't rendered correctly, so we switch to using an 8x8 equivalent background image instead.
Note: this is likely to be the last official NNL release supporting Firefox 3.6. Future NNL versions will continue to support Firefox 4+.
+ Handle Bug 521890 - Use CSS Transitions for HTML5 video controls so they fade in and out.
+ Handle Bug 692640 - Video statistics text overlaps itself on small dimension videos.
+ Handle Bug 669260 - Add statistics overlay to videocontrols. Shows framerate and other stats on top of HTML5 video.
+ Handle Bug 481082 - Video controls should listen for |stalled| event. Adds reverse-direction throbber to indicate stalled state of video playback.
+ Handle Bug 667480 - [10.7] Update Firefox’s Toolbar Button Style for OS X Lion. Adds chrome://browser/skin/lion/Toolbar.png. Thanks Anton and Red_Fat_Lazy_Cat for help.
+ For blocklist popup, richlistitem background image should not repeat. This became an issue when very-large add-on icons started being used in the list.
+ For add-on Stylish 1.2.3, update toolbarbutton icon and statusbar icon styling.
+ Create new subskins for dark-border versions of the three new app button subskins, as well as for the default orange and default private purple. There are now seven subskins for the app button, and you can learn about them here.
+ For Panorama, use a smaller border radius for the expanded-stack grid view background.
+ For Panorama, use a gray stack expander button icon instead of the blue-gray one.
+ For the wide-format billboard-style update wizard, give it the same spacing below the header underline that we had for the fx3.6 update wizard.
+ Handle Bug 591699 - Wrong clickable area for "close tab group" button. Expands click target of Panorama 'Close Group' X button to go from the button itself all the way to the associated corner of the group, making it easier to click.
+ Handle Bug 663611 - display pointer cursor when hovering tab groups.
+ Handle Bug 654721 - Remove the "orphan tab" concept from Panorama. Panorama used to let you have single tabs not part of any tab group, and they were given styling in the Panorama view to look like they were in a group, even though they weren't. With Fx7, all tabs now exist within a tab group, mandating styling changes.
+ When in the Panorama view, remove borders from tabs in groups, since it's cleaner without them.
+ Handle Bug 618552 - "Undo Close Group" button does not fit for some locales. This lets height increase to work with longer (i.e. wrapped) labels.
+ Fix a problem where primary toolbarbuttons in the Tabs Toolbar were increasing that toolbar's height, which broke layout of pinned tabs in the case when you had enough tabs that tab scrolling was in effect ([positionpinnedtabs]) because pinned tabs have a fixed height and do not grow with increasing Tabs Toolbar height. We now use vertical margins and padding in a new primary toolbarbutton layout regime specific to the Tabs Toolbar.
+ Add three new subskins for coloring the Firefox button: 1) firefox-button-dark-gray-1, 2) firefox-button-dark-gray-2, and 3) firefox-button-private-purple-1. The first two apply only when NOT in private browsing, and the last one only applies when IN private browsing (restoring the original vibrant purple color from the default theme).
+ For the Firefox button (Fx4 and up) change the color used with private browsing mode from a vibrant purple to a more-refined NNL-ish maroon-purple.
+ Change the way we draw the Firefox button border when drawing some background in the titlebar (i.e., when glass and (maximized+tabsintitlebar or nightlaunch-bg-in-titlebar or subskin or persona)) to use a white outer border, but with lower opacity for lower prominence.
+ For the Firefox button, use a 2px border (as does the def theme) with white outer border to match the glass caption button styling. This is our new default-case styling, although there are some exceptions where we use a 1px border (Windows Classic) or a less-prominent outer white border (XP).
+ Work with Night Launch Companion to allow 1) optionally customizing the amount of space between the Firefox button and the toolbars below it, and 2) optionally drawing the window background in the titlebar.
+ Decrease height of Status Bar (for Fx3.6) and Add-on Bar (for Fx4 and up). The new resulting height is 24px (i.e., 22px content and 2px top border) unless increased by larger font sizes. This decreases the height by 5px for Fx3.6 and by 4px for Fx4+.
+ Further improve arrowpanel styling: use a milder gradient; add a little pale golden gray at the gradient bottom; reduce width of black surround around arrowpanel payload; and (in most cases) center the arrowhead under the target element.
+ Add styling for NewsFox and Status-4-Evar when in the Add-on Bar/Status Bar.
+ Styling updates for add-on HTTPS-Everywhere.
New in this version:
+ Improve styling of Fx4-and-up arrowpanels (such as the site identity popup, the Edit Bookmark popup, and Save Password popup). This adds a dark surround that better connects the arrowhead to the popup body, uses gradient backgrounds where before it was solid, uses semi-transparent borders so the borders have a gradient too, and vastly improves alignment and layout.
+ For arrowpanels (Fx4 and up), draw a dropshadow.
+ In the Add-ons Manager for Fx4+, hide the addon list in the case of "You don't have any add-ons of this type installed", else we see an empty richlistbox below the message, looking odd.
+ For tab-modal prompts, switch from radial gradient to uniform luminosity behind the prompt. There was too much banding with the radial gradient.
+ Styling updates for add-ons: Test Pilot, Stylish, Colorzilla, Status-4-Evar, ChatZilla, Web Developer
Under the covers:
+ For Fx7 and up, support in-Add-ons-Manager display of simple add-on options/preferences. See Bug 653637 - Provide a simple way for addons to have preferences UI.
+ Preload browsertab border-images to avoid an otherwise-noticeable delay when first launching. Not directly related, but see also bug 547787 #c21 for background. Thanks ShareBird for the tip.
+ Handle Bug 633282 - Aero glass glaze effect jumps down when status info overlay appears - for Fx6 and up.
+ In the wake of Fx6's Bug 659578 - Remember Password notification is cut off at the bottom - we no longer need to use extra spacing before the promo message text link because this is now built into the displayed message string.
+ For soft notification promo messages (see bug 618913 and friends) in the Edit Bookmarks Panel, increase the width of the Edit Bookmarks Panel content part to make the popup about the same width as in the default theme so that promo message wrapping is about the same.
+ Add styling for the Web Console's Network Inspector panel.
+ Major improvement for Error Console icons and layout.
+ Major improvement for icons and layout when using add-on Console2.
+ For Fx4+, fix a layout problem with the app picker dialog that opens from the Options window's applications pane when picking 'Use other...' for an item in the list of content types. (This has no impact on the Mac or on Linux, where Firefox uses a native OS dialog instead of the XUL app picker dialog.)
+ Remove support for the Splash add-on since it doesn't exist for Fx3.6/Fx4+.
+ More for the Mac tooltip rendering error: don't suppress top margin on tooltip label if it follows a hidden tooltip label. This fixes a problem that happened when bookmarks in the bookmarks toolbar have no name (e.g., by editing properties), in which case the url part of the tooltip was touching the top edge of the tooltip border.
+ Switch back to our time-tested silvery throbber instead of the bright orange one. People who want to keep the orange throbber can use this userstyle.
+ Add NNL styling for about:support.
+ Provide NNL-styled toolbarbutton icons for Adblock Plus.
+ Work around the tooltip rendering error on the Mac with Fx4. (See bug 660548.)
Under the covers:
+ For Fx6 and Bug 577721 - allow repositioning of the web console: above, below and out into a panel/window - add styling for the web console as a detached, floating panel.
+ For Fx6, handle Bug 618913 - Implement in product notifications to set up Sync. This adds a low-impact, unobtrusive "soft notification" that appears at the bottom of the edit bookmark and save password popup panels. It's used to promote Sync now and may be used to highlight other Firefox features in the future.
+ For Fx6, handle Bug 656269 - Add link to Mozilla plugin check from Add-ons Manager. It's a button, but we style it as a .text-link since it opens a new page.
+ For Fx6, handle Bug 573176 - Implement Site-Specific Privacy Preferences. about:permissions is a new way of managing site-specific permissions.
+ For Fx6, handle Bug 595848 - Support registering custom add-on types that appear in the UI as a regular list. This bug programmatically generates IDs instead of assigning them statically in XUL. For extensions, themes, languages and plugins, the assigned ID has changed, so we change the CSS to match.
+ Update maxVersion to 7.0a1.
+ Bumps maxVersion to include Fx6a1 in the compatibility range.
This first release is a Windows-only version. A version with support for both Linux and Mac is almost done and is available as a beta here:
That link leads to a beta version with a separate add-on id that'll install along-side NNL (so it doesn't mess up automatic updates from AMO). It's mostly done, but if you see any problems please say so on the support thread at MozillaZine. As soon as it's ready it'll go to AMO (last time, it took about 8 days from submission to approval) and you'll get your NNL update automatically, like always. Thanks for your help and patience.
+ For add-on Colorzilla, styles the new dropmarker in the statusbar.
+ For the main Options/Preferences window, makes the background image gradient work even with a resizable Options/Preferences window. (You can resize it on Linux by default, on Windows if add-on MR Tech Toolkit installed, and not at all on the Mac.)
+ Toolbarbuttons, when checked and on the customize toolbars window, now look like all the other toolbarbuttons there (and don't look checked).
+ For Sage on Mac, uses NNL-styled icon in checked state.
+ Restores the ability to use this theme at the same time as a Persona.
+ Drops support for Firefox 3.5. Now compatible with Fx3.6 only.
+ This is likely to be the last release supporting Firefox 3.5. Now, on to Firefox 4!
+ For Mozilla add-on Test Pilot 1.0.1, restores styling for Settings on the "All Your Studies" window.
+ For OS X only, adds spacing in the statusbar so the window resizer has its own place.
+ Adds support for Mozilla add-on Add-ons Collector (formerly Bandwagon) version 1.1.1.
+ Adds support for notification highlighting of new add-ons in Add-ons Manager by adding a colored strip along the side of newly-installed add-ons. Note that this applies only to installation of new add-ons, not to updates of already-installed add-ons.
+ For add-on Faviconize Tab, reduces width of browser tab while in faviconized state and centers favicon in the tab.
+ For add-on MR Tech Toolkit, adds styling to the sort button in bottom right corner of Add-ons Manager.
+ For add-on Bar Tab, makes the browser tab background fully opaque but keeps the half-opacity of tab icon, text, and close button. As delivered, Bar Tab was making it hard to tell the difference between the selected tab and the others.
