Adobe Flash player stopped working with Firefox 43.0. How can I fix this?
On Firefox 42, Flash was working properly but after updating to 43.0 some websites give me an error that the Flash plugin failed to load. For example the following site: http://www.roosterteeth.com/episode/rwby-season-3-volume-3-chapter-6-fall
Also, when I go to this adobe site, the Flash video that plays only if Flash is working doesn't play https://www.adobe.com/software/flash/about/
I tried going to the above Adobe site on my other computer which still had Firefox 42.0 and it loaded the video properly but upon updating to 43.0, the video stopped loading on my other computer as well.
I've tried to fix the problem by doing the following with no success: 1. Restarted Firefox 2. Uninstalled and reinstalled Flash 3. Restarted Windows 4. In the list of Firefox plugins at about:addons I made sure that Shockwave Flash was set to "Always Activate" 5. Deleted the Firefox cache and restarted Firefox
I'm using Windows 10 64-bit
It seems like the problem was an add-on called "Focus Regainer". After disabling it, Flash is now working.Read this answer in context 8
