What happened to Firefox?

Question

Mozilla

Something happened to my Firefox 28. OS X 10.9.2 system. Many sites don't work. Cleared the cache, cookies, disabled all plugins... Doesn't help. It's not even normal for me to formulate the problem, the feeling that AJAX does not work. A few examples:

An article on Evernote loads endlessly:


When a post is saved to drafts or published, the action occurs, but there is no redirect, only an endlessly executing button is shown:


Recently, they wrote about Pintask on Habré , when you switch to the service, only a white screen is visible.

Since the discovery of these problems, no plugins have been installed in the near future. The set has been around for a long time.

If I do all the same in a private window, then everything works.

What the hell, please help.

UPD: I noticed that StackEdit has also stopped working , LocalStorage is there and writes that the browser is not supported. Maybe I put something in about: confing somewhere?

Answer 1

As an option, check the adblock settings, you could block, for example, some kind of static url jquery

Answer 2

Do other browsers work fine? You might not have installed plugins, but they might have been updated. But since the plugins were disabled, it's not them.

Answer 3

I have the same problem and for a very long time, I still haven’t found a solution, sometimes everything works stably, sometimes some sites don’t work) at these moments I use chrome

Answer 4

Help -> Restart with Add-ons Disabled

Answer 5

Unlikely, of course, but still...
The client recently had a similar case - some sites did not open. It turned out the matter was in the antivirus - NOD32. As soon as the node was removed, everything immediately worked.
