Add-ons automatically disabling after computer restart

My add-ons are enabled, but after I shut down my computer then restart and open Firefox, in addition to my homepage tab, multiple tabs are opening, each one saying the same thing: "Install Add-On (name)". When I check, the add-ons have somehow been disabled and I have to enable them again. Everything runs fine after that, until it's time to shut down, and then the same thing happens again next time I start the computer. Help!

hi dfreling, this sounds like some configuration changes can't be properly saved in your firefox profile folder. in order to troubleshoot this, please go through the steps mentioned in How to fix preferences that won't save

It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":

If you see disabled or not compatible extensions in "Firefox menu button/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search bar to check if there is a compatibility update available.

If this hasn't helped then also delete the addons.json file.
