hi ok this is my problem, i noticed adblock plus or any other addon not working today and after trying a few things it came down to uninstalling firefox and reinstalling my addons everything worked fine after install and testing but then i did some basic changes in options for home and privacy settings like i always have done on this and my other computers

setting homepage, removing search options and never remember history

Newly installed extensions are disabled by default in Private Browsing mode. You need to enable them explicitly for PB mode via its detail page (click the extension on about:addons). You will notice a "Run in Private Window" setting.

I am attaching a couple screenshots with more context for cor-el's reply if you didn't immediately find that setting.

My add-ons are randomly stopping working....no change in settings, no blips on the screen. They won't work at all. I disabled then enabled them...no change. I have tried fixes described but they don't work either. They work one minute and not the next and I am upgraded to the most recent version. It is maddening!
