If i start firefox normally it is invisible.
If i start firefox normally it is invisible, altough if i start firefox in safe mode by pressing shift at startup, it works normally except that sometimes it glitches, some parts become invisible and then it become fully invisible so i need to restart it. Im pretty sure that it's not something wrong with my settings, plugins or custom scripts cause this happened just before the update (see version in troubleshooting log).

After the update not before sorry...
Check your zoom controls.
<Control> (Mac=<Command>) + (plus) enlarge - (minus) reduce 0 (zero) restore
If this fixes the issue; It appears to be an issue that only affects users who have turned off ClearType font rendering within their windows settings. So a workaround for the moment would either be to turn ClearType back on or disabling hardware acceleration in Firefox: Firefox's performance settings How to Tweak ClearType in Windows for Better Screen {web link}
