Hi tzic, Firefox's Safe Mode disables some font smoothing because it disables Firefox from using hardware acceleration. You can try running with that disabled for a while (in regular mode) to see whether you lose out on other features important to you. If so, instead you could try to fine-tune Firefox's font smoothing settings.

Hi, I have no problem with what your suggesting is wrong and i do not have my glasses on not did I zoom in.

If you think there is something wrong please try this since we have no information  : 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 > Performance > Uncheck to view)
  • plugins are not affected
  • preferences are not affected

TEST''''is issue still there ?

If so please : Refresh but Note that this does more than uninstalling and re-installing does. Normal uninstalling does not remove some preferences which may have become corrupt. Please Refresh but do this 1st:

then

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

running in safe mode fixes the fonts. But I cant find where is the problem. I only have 3 addons that I use daily. Disabling those does not solve it. So it must be something else

The following setting makes some difference. You can try it out and see whether it helps, or whether the only good workaround is disabling hardware acceleration.

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste font_r and pause while the list is filtered

(3) Double-click the gfx.font_rendering.cleartype_params.rendering_mode preference and change the value from -1 to 2 and then click OK

You probably need to exit and start Firefox back up again to see any difference.

Example screenshots attached.


Here's my understanding of what the numbers do (as of Firefox 45):

Font smoothing using sub-pixel anti-aliasing/positioning

//     -1 or 0 = use default for font & size;
//     4 = Natural;
//     5 = Natural Symmetric

GDI emulation (whole pixel rendering)

//     1 = aliased;
//     2 = GDI Classic;
//     3 = GDI Natural Widths;

I don't know which one is closest to Chrome.
