Anyone having trouble with sans serif fonts on websites like FB and youtube comign out jaggy and badly rendered? This has happened recently, like since 64 was released. It seems to effect everything in the mozilla/firefox window including menus. I checked and other browsers aren't having this problem.

Tried changing the hardware acceleration and the usual. Also uninstalled/reinstalled/restarted.

There is no FF64 public release and if you using beta FF you should use the public release to insure there isn't a bug causing the feature. Beta release should be used for testing purpose only.

Westend the OP was referring to the 64-bit (Win64) Firefox for Windows as Win64 has existed for Release since Fx 42.0.

Firefox 64.0 will not be on Nightly channel until September.

You can try to disable hardware acceleration in Firefox.

Close and restart Firefox after modifying the setting to make the change effective.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
