I can't login to Adobe or the forum using Firefox (v30.0) Mac, which is my main browser. I'm only logged in right now using Safari.
Here is a screen shot of the errors in the error console.
I see this problem in archived threads, and they seemed to have solved it by disabling the extension HTTPS-Anywhere, but I don't have that extension.
Best thing is to clear the browser cache because Firefox has the tendency to keep the cache for a very long time even when they have expired.
As far as I can tell Firefox 30 is beta. Report the issue to Mozilla. We cannot support other company’s beta software.
Firefox 30.0 Mac is out of beta now.
You are right. Somehow I was in the beta channel. By the time I made this reply, I was already up to Firefox 31, which had the same problem.
I just did a clean install of Firefox, and got off the beta channel, however the problem is that I'm still now with Firefox 30 and it has the same problem.
It's weird. When I go to login, the page hangs, but when I leave the page to go to another Adobe page, I'm already logged in.
However if I try to do anything like see my licenses, I get sent back to the login page and it hangs.
Here I am again, posting from Safari.
The Beta Channel itself is not the Problem. Do as the annotation in the screen shoot says. You will have to resign in to the Forums or to the portion of acrobat you removed them from. If you have been having issues with signing in sticking after they switched to this new system, deep-sixing the cookies for the forums and resigning in should cure it.
