When typing into a web page, after 2 letters my firefox freezes says 'not responding' for 20 seconds + before allowing me to continue typing? Do I have a bug?
When typing into any webpage, ie updating Facebook, my blog, logging into banking etc, and also when typing in this message now, I type two characters and then no more appear. After about 5 seconds I will get a message saying 'not responding' and about another 15 to 20 seconds later one more letter typed will appear and I can then continue typing.
I'm inevitably paranoid it's a virus and have virus checked several times.
NB it has happened twice while I've been writing this. Once after I'd typed the first 2 letters of the first sentence, and a second time in the middle of writing 'checked' in the sentence two before this one.

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox Profile Folder that store session data.
Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.

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).
