Firefox bugs affecting MediaWiki

This is a list of known Firefox bugs that affect MediaWiki sites such as Wikipedia.

The aim is to create a list of the top 10 bugs that affect MediaWiki. If we can get a consensus on what these bugs are, we may be able to officially submit a request from the Wikimedia Foundation to the Mozilla Foundation to address these issues with some priority.


 * Bug 126309: Save page does not save @import -ed CSS - this makes saved pages from Wikipedia very ugly, as the required screen stylesheet is not saved together with the page.
 * Bug 79021: All stylesheets are loaded regardless of rendering media - Results in loading stylesheets that are not required, which makes the Wikipedia load slower and with more bandwidth used than is necessary (although it does still work).
 * Bug 366797: Revise the Location Bar - Instead of showing encoded URLs like http://uk.wikipedia.org/wiki/%D0%92%D1%96%D0%BA%D1%96%D0%BF%D0%B5%D0%B4%D1%96%D1%8F in the address bar, show stuff like http://uk.wikipedia.org/wiki/Вікіпедія (which a Ukrainian speaker could presumably understand, versus no hope of understanding the earlier version).
 * Bug 372474: After "save page as, complete" opening the saved page is missing all images - encoded image filenames in saved HTML.
 * Bug 115107: CSS not fixed up by webbrowserpersist ("save page as, complete" omits background images) - Relative links to images or other media included in CSS are not resolved when saving a local copy. Currently not an issue until bug 126309 is fixed, but then will be a problem.  Absolute links will work but require web connection.

Fixed bugs

 * Bug 218277: losing Unicode no-break spaces - saving article with Firefox will convert all no-break spaces 0xA0 into standard spaces 0x20. Mostly affects French and Russian Wikipedias. Fixed only in Firefox3.
