I'm using AOL for email and Firefox 9.0.1. Problem started 2 days ago. Before that I put in the first two letters of an email address and it gave me a list of possibles. Now I get "undefined" for each possible instead of the email address.

After updating to Firefox 9.0.1 there were no problems. My contact list still shows as it did before this problem arose. When I type in the first letter or two of the email address, it used to give me a list of possibles. Now t is just showing the email address as "undefined" when it gives me suggestions for the email address I'm typing in the send line. This means that instead of being able to click on my choice in the possibles it gives me, I have to go to my contact list, find the name and then click on it if I'm sending the email to one person. If it goes to more than one, I either have to type in the full address or use copy and paste from the contact list. This is a huge hassle. Any help is appreciated.

Isisombululo esikhethiwe

Are you using any cleanup software like CCleaner?

It is possible that there is a problem with the file that stores the "Saved Form" data.
Rename or delete formhistory.sqlite (plus formhistory.sqlite-journal and formhistory.sqlite.corrupt, if they exist) in the Firefox Profile Folder in case there is a problem with the file that stores the "Saved Form" data.
That will remove all saved form data, so you may want to rename formhistory.sqlite to formhistory.sqlite.sav or move the file to another folder in case you need to recover some saved data.
If that has worked then you can remove the renamed files.


Start Firefox in Diagnose Firefox issues using Troubleshoot Mode 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).

Additional information on my problem. I attempted to add a new contact to my list this morning. It simply wouldn't save it. It's as though Firefox doesn't recognize my contact list exists. What can I do to get this back?

I moved the file formhistory.sqlite to another file folder. I then started Firefox up again to see if it worked or if I needed to start it in Safe Mode. No need for Safe Mode. It now works exactly as it should. Thank you so much!!
