Hi Bombaywalla,
I’d feel pretty certain that the out-of-date Adobe Reader is unrelated to the problem. And in fact I’m still using Adobe Reader XI, because when I briefly updated to DC some time ago I didn’t care for it (I don’t remember why).
Also, I’ve never bothered to "research" the plug-ins FF reports as unknown.
What I’d suggest that you do at this point is some combination of the following:
1)Under Tools/Add-ons/Plug-ins, change the setting for Flash from "always activate" to "ask to activate." Then only give it permission to activate when it is necessary to view something you want to see.
2)Under "Options," right next to the "ask to activate" setting for Flash, disable protected mode. See this writeup. (Although I have been running with protected mode in its default state of enabled, with no problems).
3)Try what DJohnson54 and I said about running in safe mode. As indicated in the link DJ provided, to start in safe mode just hold down the shift key while starting Firefox. As I indicated, if FF runs smoothly in safe mode it most likely means that a plug-in or extension is causing the trouble. Which particular plug-in or extension can be identified by selectively disabling them while running in normal mode.
Best regards,
