I desperately would like to update Firefox to version 10 from version 9 but each time I try, I am stuck with FF10 checking addons for comparability and the Welcome page opening every time I start the browser.

Sorry to be a while getting back! Tried all of that with no sucess so this AM, bit the bullet and deleted the FF folder from programs and downloaded and installed FF 10.01. Still was plagued with the same problem. Went into the appdata folder and there were two sessionstore.js files. Deleted them both, restarted the browser and no compatibility check for add-ons was done at start up and the extra tab for Welcome to FF was no longer opening Everything seems to be working as it should and I did not loose any of my settings.. Thank you for trying to help and I hope my solution helps anyone else who might experience this in the future. Here's hoping the next update goes smoother!

I had all ready tried all of the suggestions there but it makes no difference. As soon as I apply the update I am faced with the recurring Welcome page and check for compatibility of plugins with each start of Firefox 10.01. I have been using system restore to roll back before the update and reinstalling FF 9.01 overtop of itself and it fixes the problem but really want to do the update and not lose all of my settings.

Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
