Firefox being odd

[Niall]

For some reason, when I click a link on a site/forum etc, instead of opening in another tab as it's always done, it now opens a new window. I haven't changed any settings, so I don't know why it's doing it.

Also, it seems to have forgotten how to remember logins for pages, like these forums. When I changed my password the other week after the problems, Firefox decided that it won't remember the new login/password combination.

Anyone know why this has started happening? Everything else seems fine. No malware, viruses or anything of that nastiness. I'm baffled.

Sounds like a corrupt Firefox profile - http://support.mozilla.com/en-US/kb/profiles

Well I managed to sort out the tab thing, simply by closing Firefox and clearing everything with Ccleaner. On restart it worked again. I still can't get it to remember the password for these forums though.

Ah ha! It was the private browsing session. As I only visit a few sites that require info from me, until removing my password from Firefox, I wasn't aware it didn't remember new passwords if run in private sessions. Unticking that allows you to remember a new password. Hurrah

Aye aye, what have you been surfing then?

Nothing dodgy I was just wondering what difference it made months ago, then changed it

Good good. I spent half an hour looking for something right in front of me, that I'd seen all that time. I'm still in my 20s. Don't know how I'm going to cope. 
(I think rushing anything you end up missing the obvious)

Useful to know that, Niall, somebody else is bound to fall foul of the same problem.
