Firefox, despite being fully updated, freezes up many times per minute, especially while typing. When the browser unfreezes the letters that have been typed are out of order and the words generally have characters I have not even used while typing. I had this problem when I first installed Firefox on this computer last month but an update was available at the time and it fixed the problem. A few weeks later the issue reappeared. I have to type one word at a time to make sure things show up the right way which is incredibly frustrating for someone like me that types really fast. :o(

The following is an example of what this issue is causing: I am a great tinter eal lyin te really interfering with my ability to type effecty and effectively. I hope someone can teb ecau sei te because it impacts everything I do online.

Chosen solution

Start Firefox in Use Troubleshoot Mode in Firefox to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

Delete the files sessionstore.js [2] and sessionstore.bak in the Firefox Profile Folder.

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
