Tabs were looking fine in FF 49. I upgraded to V.50.0.2 and now all active tabs are painted with a rectangular background region instead of over the full tab area. Please see attached picture. I've disabled all the addons that might even be remotely suspiciousm cleaned the cache, rebooted the machine - no change.

However, if I create a new profile, the tabs are rendered correctly as was the case before the upgrade. I am trying to avoid a permanent creation of a new profile and migrate everything that I've got to the new profile. If there is a simple solution to this, I'd be thankful.

Running under WIN7 32bit.

Chosen solution

Thanks for the pointer. Although I have not found the root cause, I may have a solution that suits me afterall.

1. I started FF in safe mode (HW acceleration has always been off ) - still show the problem. 2. Then I noticed that if I switch a theme to anything in the provided list OTHER THAN THE DEFAULT THEME, the tabs now look OK. 3. My solution is now just to find a theme that I like (I've always used the DEFAULT) and circumvent the issue.

The root of the problem may lie in one of my old custimazions of the options available through the about:config , but I loathe the thought to go through the options by a way of elimination, Finding a suitable theme is so much faster...

Thanks again.

Gotta be an add-on (extension) or a user customization causing that glitch on the tab-strip.
