Forgot to mention...If using Windows, you may wish to download and use
MozBackup to create a backup copy of your Firefox Profile. This will minimise difficulties if your profile folder should become corrupted. Your Bookmarks, Extensions, and cookies are saved, and can be restored. Unfortunately, it only works in Windows at this time. It also works for the Thunderbird Email client.
Thanks tons.
I have Spy Sweeper. Will check out the freeware you've mentioned though I'm somewhat allergic to freeware from past problems with lots of it.
I realize FireFox is loads better than IE generally. Just had gathered, that like all human indeavors, it wasn't perfect either. Figured you'd know more than most.
Thanks much.
