Adds are instaled and later its gone
Hello Firefox support. I don't want to take lots of your time but i have a kinda problem... Idk how it works but fore example I install the Add block once and after I shut down the Web browser and run it like 10min after that add-on is gone. i did try it with other versions of Add block and its the same... Install -> shut down the Firefox -> open again and its gone. I did try to look in an internet a bit but didn't find anything interesting.. its like i didn't install it at all o.O i did try that again and again many times. I hope you could help me with that.
TYVM fore your time and have a nice day

It is possible that there is a problem with files in the profile folder that store the extensions registry.
Delete the extensions.* files (e.g. extensions.json, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
New files will be created when required.

If you see disabled or not compatible extensions in ""3-bar" menu button/Tools > Add-ons > Extensions" then click the cogwheel button (left of Search bar) to check if there is a compatibility update available.
If this didn't help then delete add-ons.json and possibly prefs.js in case there is a problem with preferences.

Hello It seems it works
Ty fore your help
My ability to see the add-ons install on Firefox is gone. The page will not display. I can't get potential add-ons to display. I am not sure if it is related on not but I looked at Personas Rotator add-on but didn't install it. Now it appears every time I start Firefox on the tab after my home page. Thanks. I am not tech savvy so please help me with step by step. Old woman can learn new things! You help is truly appreciated. Leiaj
