Note: Edge on Win10 does not use ActiveX version but its own Flash.

I appreciate the response but I'm still having problems. See my original post for o.s. information--Win7 Home Premium 64bit, Firefox 40.0.3, though I've tried reverting to previous releases of Firefox (29, 39, etc) with the same result. I've neither added nor deleted any software since this problem started in the last couple of days. I can't even click on any movie listed in Netflix now without it crashing Firefox when attempting to open the movie. (this is a full-tilt crash, not a hanging issue; the browser closes and the "we're sorry, but Firefox has crashed" window appears with options to "quit Firefox" or "re-start it". As mentioned before, Adobe Flash works perfectly in IE 11, as do any YouTube videos or anything else I want to watch in IE.. Firefox up to now has been my default browser but I'm losing faith quickly. Again, thanks for the response.

You can check for issues caused by plugins and set plugins to "Ask to Activate" on the "Firefox/Tools > Add-ons > Plugins" page.

• plugins are not affected by Firefox Safe Mode

You can check for problems with current Shockwave Flash plugin versions and try this:

• make sure you have the latest Flash version:

You can try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

Just to let any and all know, I solved the problem but in a roundabout way. I was in the middle of trying to update a graphics driver and ended up getting my computer into a state where it wouldn't boot. I resorted to rolling it back with a system restore to last month's backup and I managed to solve the Flash conflict in the process. Being that I hadn't added any new software and/or made any changes to the system over the past month since that backup, I'm still not sure why the conflict started or what caused it. Either way, it's solved for the time being. Thanks for the posts and I'll return if I have any further problems. Regards.

That was very good work. Well Done. Please flag your last post as Solved Problem so others will know.
