Approximately two weeks ago it all began: I noticed that (some) letters in the text are blurred, distorted (or, twisted) on almost every webpage, so eventually you it`s hard to discern what`s written. And, as for the icon for my Facebook account (I mean, my picture with or, next to comment option) it turned into black color, just black square and it doesn`t disappear. Strange thing is that I tried it on Opera browser or, Chrome, and there are no such problems there. But because I love Mozilla Firefox it makes me sad. Please, help. Thank you, very much!

Did you zoom in your browser, try to reset (CTRL + 0)


Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).

(If you're using an added theme, switch to the Default theme.)

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the Restart with Add-ons Disabled... menu item:
FirefoxSafeMode

If Firefox is not running, you can start Firefox in Safe Mode as follows:

  • On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
  • On Mac: Hold the option key while starting Firefox.
  • On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
    (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

Once you get the pop-up, just select "'Start in Safe Mode" Safe Mode Fx 15 - Win

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Thank you.

You can try to disable hardware acceleration in Firefox (you need to close and restart Firefox).

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

Try to disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled.

That way you still have the benefit from hardware acceleration, but may not suffer from rendering issues.
