Unable to close Firefox after latest update & newest version of Adobe Flashplayer 26 NPAPI?

Firefox updated today. Then I uninstalled Adobe add-in which had been disabled by Firefox previously. I downloaded & installed the latest version of Adobe Flashplayer (26.0.0.151), which Firefox allowed to activate just fine. I later tried to shutdown Firefox (File| Exit) and was unable to do so; clicking the X in upper right hand corner did not work either. I used Task Manager to close Firefox, reopened it and disabled Flashplayer. Firefox still wouldn't close normally. I then loaded Firefox in Safe Mode and then was able to close it using the X from the upper right hand corner...

I don't think Adobe caused the problem, but I was able to exit in Safe Mode, which turned everything off.

Prior to this latest Firefox update I hadn't had any problem with exiting the browser.

Obviously, I can't keep using Task Manager to exit Firefox all the time... I'm at a bit of a loss here.

Chosen solution

Disabling Tab Mix Plus fixed the problem with exiting Firefox 55.0.2 but then I didn't have its functionality.

So, I installed the latest development build of Tab Mix Plus 0.5.0.4pre.170818a1 and it worked just find --and-- does not have the problem of preventing Firefox from closing normally.

Thanx for getting me on the right track!
