It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}
Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)
In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.
Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.
If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.
Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.

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}

If not then the link? So others can see what it does.
Make sure you are not blocking content.
Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Well, in Safe mode the problem disappearing, but this not resolving the problem in "normal" mode
What should I do now?
