I just installed the newest FF ersion on my laptop running WIndows 10 with the latest updates. When I turn on the built in dark theme that FF comes with, the top right corner buttons doesn't get themed, they just turn white. If I hover over them, they turn blue which I think is expected. If I turn the theme to white again, they look ok. I have tried running safe mode, didn't seem to make any different.

The built in image function in the forum doesn't work, take a look here: https://imgur.com/a/D8QpB

Hi, ya strange. I suspect a corrupted file or packet loss in download for now. Please : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 59.0 with a Full Version Installer

Please let us know if this solved your issue or if need further assistance.

Is the Firefox window maximized?

You can also try to set this pref to false on the about:config page.

  • browser.tabs.drawInTitlebar

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

It kinda works, but then I loose about 10px in the top bar and it looks kinda ugly.

Hi, I just tried this. The problem is that after uninstallation of FF, I don't have anything named Firefox or Mozilla in the directories you told me about. I ran disk clean, rebooted and installed FF again, still the same problem.

Hi, that is ok, the uninstaller is better than it used to be. Sorry did not fix that. Could you please try these please : SAFE MODE

In Firefox Safe mode these changes are effective:

  • all extensions are disabled (about:addons)
  • default theme is used (no persona)
  • userChrome.css and userContent.css are ignored (chrome folder)
  • default toolbar layout is used (file: localstore-safe.rdf)
  • Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
  • hardware acceleration is disabled (Options > Advanced > General)
  • plugins are not affected
  • preferences are not affected

TEST.....................................................is the problem still there ??? If is please try : Profile : Make a new one and test ...:

If is your Profile :

As not mentioning if using old/same profile or a new one or installing the add-ons before finding out there is still issues. with Dark Theme. Also try another theme to see if it effects them : https://addons.mozilla.org/en-US/firefox/themes/

I have already tried safe mode but I tried it again now for good measure, but it did not fix the issue. I also tried creating a new profile according to your link, still the same issue. White and default themes work fine but applying dark theme causes my issue.
