The "About Firefox" page in help shows me on 38.0.5, and has a button to allow update to the current release, so I am confident going back to the current release would be easy.
I use Norton as anti virus, so I'm not sure how protected I am, but I am happy to be able to use FF again. I have since watched about 30 hours of video without a single "Firefox is not responding", or a flash crash.
I know that someone will comment that doing this is not advised, and that it will leave me vulnerable to attack. I really like FF, and it is my preferred browser, but it became totally unusable.Īs a last gasp try to fix the constant "Firefox is not responding" problem, I set FF to not update automatically (check for updates,but let me choose whether to install), and I installed FF 38.0.5. With FF release 41, FF began freezing on all websites using any flash content. My solution was to stop using FF for videos, and use IE. Since videos on my laptop are my only form of entertainment, I was reluctant to uninstall Flash for IE, when it was working Fine. FF support told me the problem was having two Flash Players, and to uninstall both, using Adobe's uninstall tool. I did not have any problems using IE with Flash (Active X) on the same videos. I tried all the "fixes", FF safe mode, Flash in unprotected mode, refresh FF (and rebuild tool bar, and get back classic theme), hardware acceleration, etc. Firefox began freezing "Firefox is not responding" while watching videos using flash, immediately after FF Release 40 installed.
