The main problem is firefox hangs if I click a link in a webpage, and it actually times out -- something I haven't had happen in years. I have the fastest connection, I have a fast notebook. This had never been a problem before.
 One troublehooting suggestion was to disable extensions and add-ons. I did look there, but I don't have any. There were three extensions, all disabled.
 Then I looked under the "add-ons" manager and there are a dozen. I all have them set on "ask to activate." I don't know if this is the problem. I don't want this browser using anything other than the adobe pdf file, so I have set it so it won't assume and change my pdf files. 
 I have no issues with video and sound. But the hanging and timing out is making me nuts.

 I'm open to all suggestions. Thanks,
Gina

I used to use firefox almost exclusively, it was so good. But I had to reinstall, and also there are newer versions and it has become such a troublesome browser I use the others.
