Firefox 13.0 will still only open up to the "Welcome to Firefox" page.
Please help me. Is anyone looking at fixing this?
Solved! Go to Solution.
It's possible that an extension is interfering. I think there are two things to try:
Which security software (firewall, anti-virus) do you have?
Some security software does have virtualization features that can cause problems by protecting and restoring files in the Firefox profile folder.
Had this problem on a couple pages. It was my ad block plus. I disabled and the page came up ok, and then I reinabled, and all is fine.
I'm using McAfee, which hasn't had a problem with Firefox getting updated before. Did Firefox change how it's doing things so that McAfee objects?
I'm thinking of switching to AVG, though. Does Firefox have problems with that one?
Wouldn't disabling your Mcaffee for a few minutes help you determine if it was the culprit?
I use NAV and MSE on my computers and firefox is fine with them.
I did revert back to FF 12 though. Too many kinks in 13 still.
Firefox has upgraded many times before with McAfee installed. Has Firefox changed how it upgrades so it no longer works with McAfee?
FF 13 is pretty clearly broken in some ways, and no one seems to have any clue how to fix it. I sure hope Firefox handles security issues better than upgrade issues. This does NOT inspire confidence.
So, how does one revert back to 12? That seems to be the best answer.
That worked. Thanks, my Firefox may now be out of date. But at least it works right.
