Tab background color changes when saving or downloading (Ubuntu) - bug ?

I'm using Firefox 20.0 on Linux Ubuntu. When I'm opening and using Firefox, the active tab background is light gray, and the other tabs are black (with white/gray text). But as soon as I have downloaded a file (saving an image for example, or a pdf), the tabs change color: the non active tabs turn gray instead of black, and the tab text is almost unreadable (gray on gray).

I have disabled ALL extensions (including the Ubuntu/Unity extensions) and restarted Firefox, and get the same result. See screenshot with before/after downloading: http://imagesup.net/?di=113687926169

On the other hand, when I start Firefox in safe mode, all is well, the tabs don't change color when downloading or saving a file.

What to do? Could this be a bug ?

Hey, I'm on Ubuntu, too.

It seems like you don't use Ubuntu's default theme, or at least, you have some modifications there, right? Try disabling your customizations to see if it works, I never saw / heard of this problem anywhere.

Also update your Firefox, there are changes that your problem is fixed after updating.

Another suggestion would be hacking about:config, for example, it might be the Download Manager's arrow flashing ( just guessing ), so you might want to disable that and see if something changes.

search 'browser.download.manager' in about:config and play with those configs to see if anything changes.

I've been trying out some of your suggestions.

I noticed that it had to do with the Ambiance theme that I used - changing it to a different theme (using Ubuntu Tweak) solved the problem - but I like the Ambiance dark background better.

The solution was this: in auto:config, set browser.download.useToolkitUI to true ( which gives the classic download window). The tab color change disappeared - problem solved, still using the Ambiance theme.

Thanks for your hints.
