As of today´s update to 87.0 FF has become virtually unuseable on many sites. Tab titles, website address line and contents of websites that were fine so far display missing or pink singular letters or whole lines of text are made up of blackened squares and rectangles. Upon marking said lines the correct text is visible. What´s going on? Cache and cookies clear, rebooted, still same problem. Hesitant about wiping account regarding having to reinstall all addins that have been running fine for years. Deleted Kaspersky addin in hopes it was the culprit. Unfortunately, no. Any ideas anyone?

You can try to disable hardware acceleration in Firefox.

Close and restart Firefox after modifying the setting for changes to take effect.

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