Hi, I'm sorry you're having this problem with Firefox, can you tell me what version you upgraded from? Also, you might try Diagnose Firefox issues using Troubleshoot Mode starting Firefox in Safe Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

Let me know if you need more help.

Thanks, Michelle

If you keep tabs on all the time, perhaps that would help as a temporary workaround?

Tools menu > Options > Tabs

check the box for "Always show the tab bar"

Does it help if you disable Aero or select another background color?

It was 12.0 that caused the issue. I just downgraded back to 11.0

I Think I understand your problem.

This is not a new development and the solution is somewhere on this support but I can not find it anymore. I just reinstalled win 7 and therefor a new FF that reinstated this supposed "improvement" grrr I found the below and changed it from "true" to" false" and voila it's back to all white.

go to "about:config" and search for the below.

browser.urlbar.formatting.enabled <--change from true to false

Hi whatdoi, I think that preference is only supposed to affect the colors of the wording in the URL, and not the background color (browser.urlbar.formatting.enabled - MDN). Do you find that it affects the background color of the navigation toolbar as well?
