I have FF 13.0 and it works just fine, did not notice any difference prior to or after update.
Are you sure that you're logged in?
Google’s dominion in Internet search is all I can take.
I wouldn’t use a single Google product I did not have to.
My Firefox, 13.0 in Win7 is working excellent.
Have you tried any of these suggestions?
Have you fully shut down Firefox, checked to make sure it was gone using the Task Manage, and then restarted it?
It tends to have memory leaks.
The last 3 FF versions have been a bit glitchy here,, web pages have so many bells and whistles these days, I think my laptop has reached a golden age and I need a new one to keep up memory management-wise,, It’s nice to have options.
Firefox. Just like AVG.
Started out great.
Turned to crap.
i am NOT happy with some of the changes they've made...
I had an issue with Firefox and Chrome being non compatible. When I downloaded Chrome to try it my Firefox started acting up and the Chrome did not work well either. I forgot where I found it but the advice was to uninstall Chrome and my Firefox has worked well ever since. It seems to be one or the other which is kind of strange since the latest Firefox comes with all sorts of Google promos.
Yes FF is getting slower the crap. Mine updated to 13 last night and it has a few weird quirks I don’t like. But just wait a few months and it will change back or to some other quirk! LOL
