I have been using Firefox and IE 9.0 daily for months.
I've never had a problem with Firefox until yesterday. It crashed two times and again once today. I got a popup message saying it had crashed.
My version is 3.6.17
1. Which version should be used for best compatibility with Vista, Hotmail, IE 9.0, etc.?
2. If I upgrade my version, will my bookmarks be saved?
3. What are any new vulnerabilities of Firefox?
A. It seems to store more tracking cookies than IE.
B. Vista Anti-virus 2011 (a fake) was apparantly linked to Firefox. Is IE 9.0 just as vulnerable to this new fake program?
