Add-ons/Reviewers/Guide/CompleteThemes

Complete themes are less security-sensitive than other add-ons, so it doesn't take much for a theme to pass preliminary review. However, to obtain full review, lots of attention to detail is required in the review. There's also the special case of multi-package installers, which are generally used to bundle a theme and a configuration extension. In this case both an extension review and an add-on review are necessary.

Basic testing

Testing should be done on a new profile. The code validator doesn't have many useful tests for themes, but it should flag if there's any code in the theme. Reject if that's the case.

While reviewing themes, watch the Browser Console console for any CSS warnings that are flagged for chrome paths containing the word "skin". Warnings should be copied from the error console and pasted into review notes for the developer to investigate. Generally, warnings about CSS issues should not be grounds for withholding a full review of a theme. However, providing notes to developers about CSS issues can be tremendously helpful to theme development.

Issue	Action	Notes
Text and/or buttons are difficult to read.	Preliminary review
Theme has an inconsistent look.	Preliminary review	You should avoid judging a theme for thinking it looks ugly, since it is a very subjective metric. However, themes should be consistent about their look.
UI elements don't fit within their boundaries and appear "clipped".	Add note	This is relevant for menus and dialogs. If anything's clipped and/or if resizing is required to see it completely, make a note of it and request the author to address the issue.
No preview image or unsuitable preview image.	Add note

Identity Boxes

Identity boxes are an important user facing security feature that must be carefully inspected to make sure they function properly. For each style of identity box, make sure to click on the identity box icon to make sure the drop down door hanger is styled reasonably and contains the appropriate icons.

Security Level	What to test
HTTPS Extended Identity	Test URL: https://addons.mozilla.org/ Default background color: Very Light Green Default text and border color: Dark Green Identity box text: Company Name Icon: Padlock Requirement: Background, text and/or border colors must be unique from other identity boxes. Must use padlock icon. Must sufficiently stand out from rest of theme. Using the color green is strongly recommended. Sample screen capture:
HTTPS Basic Identity	Test URL: https://bugzilla.mozilla.org/ Default background color: White Default text and border color: Dark Grey Identity box text: None Icon: Padlock Requirement: Must utilize a padlock icon. Sample screen capture:
HTTPS Mixed Content	Test URL: https://people.mozilla.com/~bsterne/tests/62178/test.html Default background color: light grey Identity box text: none Icon: Globe Requirement: Must NOT use secured padlock icon (broken padlock okay). Sample screen capture:
HTTP Unsecured Connection	Test URL: http://www.mozilla.org Default background color: light grey Identity box text: none Icon: Globe Requirement: Background color must be different from HTTPS extended identity box, must NOT use padlock icon of any sort. Sample screen capture:

Test Pages

All of the following URLs should be tested.

URL	Policy on failure	What to test
about:addons	Preliminary Review Preliminary Review	Make sure formatting is reasonable. Addon type tabs need distinct icons. Make sure there is a significant difference between enabled and disabled addons. It is strongly encouraged but not required that the icons of disabled addons be greyed out. Pin this tab to make sure pinned tabs work correctly.
about:config	Add Note	Make sure it is formatted correctly. While in about config, set the following keys to aid later testing: geo.enabled=true (bool) browser.syncPromoViewsLeft=1000 (integer) security.warn_viewing_mixed=true (bool) security.warn_viewing_mixed.show_once=false (bool)
about:permissions	Add Note	Make sure it is formatted correctly. While in about:permissions, make sure that if there are entries for them, the following domains have the necessary permissions: addons.mozilla.org: Store password = Allow www.mozilla.org: Share location = Always ask
AMO Addon	Preliminary Review Preliminary Review Preliminary Review Add Note Add Note	Test RSS feed icon. Place RSS button on toolbar and make sure its appearance is different for pages that have RSS feeds from those that don't. If you don't have a live bookmark on your bookmark toolbar, add this page's feed to it. Test print preview. Make sure it is formatted reasonably. Test Fullscreen mode (F11). Make sure it is formatted reasonably and functions correctly. Log in to AMO (using a fake username/password is okay), make sure the save password panel is formatted reasonably and includes an appropriate key icon. On the save password dropdown from the identity box there is a sync "door hanger" it needs a proper border. See Bug 708797 Double click on the bookmark star in the URL bar.

Usability Tests

The Themes should be usable without Mouse - widgets have to change their appearance when tabbed through them with the keyboard. (e.g. checkboxes, radio buttons, tabs, should indicate key focus). Many of these tests can be conducted in conjunction with other tests above.

• Tab Strip: Tab through tab strip using Ctrl+Tab. Active tab should be visually different from other tabs.
• Group Tabs: Activate group tabs using Ctrl+Shift+E the highlighted tab should be visually different from other tabs use the up/down/left/right arrows to navigate from tab to tab and then press enter to open the desired tab.
• Menu Bar: Activate the file menu using Alt+F and then use keyboard to navigate through menus and sub-menus. The selected menu item must be visually different and the highlighted text must be legible.
• Places: In the places (History/Bookmarks) panel tab around and use keyboard arrows to navigate. Make sure it is visible what the selected item is.
• Options: Open the options panel and make sure you can navigate around the options panel and that you know what has focus. You must be able to change tabs, and settings from the keyboard.

OS Specific Issues

Linux

• Unstyled Firefox Button: On Linux, themes sometimes have improperly or totally unstyled Firefox button, and/or the Firefox button not changing styling when in private browsing mode. The primary cause of this issue is that the Firefox button has a different ID in Linux from Windows. As a result, in the browser.css file any reference to #appmenu-button also needs a comparable reference to #appmenu-toolbar-button.
• Strong Black borders Around URL Bar Door Hangers (drop down panels): Many Windows based themes make use of the box-shadow style rule, however, it is not supported on Linux Firefox and resulting in the strong black border. If the strong black border is noticed, it should be noted to the developer and they should be encouraged to make sure box-shadow style rules only target Windows.

OS-X

If you test any theme that is supposed to support OS-X please make sure that if the following files exist in "chrome://browser/skin/" they were also copied to "chrome://browser/skin/lion/":

• keyhole-circle.png
• Toolbar.png
• toolbarbutton-dropmarker.png
• tabbrowser/alltabs-box-bkgnd-icon.png
• tabview/tabview.png
• places/toolbar.png

The other solution theme developers can do is rename the files to something non-default and then make the proper file mappings in the theme's CSS files. NOTE: This issue doesn't require OS-X to test, you only need to look in the theme contents (via the "contents" or "compare" links) to see if the files in question exist. For more information see Bug 679708 and Bug 702558

Win7 w/Aero Glass Support

Win7 doesn't always go into full screen properly

Any theme that supports Aero Glass transparency needs to be tested going from a normal window to full screen. Often times when this is tried, the browser window will disappear or not go to full screen properly. When this happens, developers need to be provided the following note. See Bug 732757 and this MozillaZine thread for more information.

On Win7 with Aero Glass support Firefox doesn't always go to full screen mode from a normal window properly.
The resolution to this issue is to add the following code to your browser.css file somewhere below where the 
main-window is made transparent to support Aero glass. For more information about this issue please see 
https://bugzilla.mozilla.org/show_bug.cgi?id=732757 and http://forums.mozillazine.org/viewtopic.php?f=18&t=2438459.

Win7 sometimes missing min/max/restore/close button group when title bar disabled

On Win7 Aero, when tabs are on top and the menu bar is disabled, some themes will be missing the min/max/restore/close button on the right side of the title bar. When this happens please point the theme developer to the following MozilliaZine forum threads for the solution to this issue: http://forums.mozillazine.org/viewtopic.php?f=18&t=2131121 http://forums.mozillazine.org/viewtopic.php?f=18&t=1953371&start=60

Special Considerations

Windows and OS-X use different CSS rules to generate OS native scrollbars. As a result any cross OS theme either needs to target different scrollbar rules for each OS or use custom XUL scrollbars.
