Some of my addons are not working and some are. I have deleted all of these following the proper procedure:

extensions.json, extensions.ini, extensions.sqlite compatibility.ini add-ons.json prefs.js extensions.* %APPDATA%\Mozilla\Firefox\Profiles\ cert9.db.

I have also refreshed my firefox 2 times and started in safe mode, enabling addons one by one and scanning for malware with multiple programs. I'm still have problems with my addons, it would start to work for a few hours, then it would be greyed out and stop working and will only work if close and open the browser again. I have no idea what happened, please help me.

Did you check if they are not legacy addons? And did you uninstall the addon before reinstalling them? What you seem to describe sounds more like they are addons that are being disabled.

Hi oceanave, is it the same add-on(s) that stop working each time? You might try to contact their developers and see whether they are aware of this problem, or whether possibly some of your add-ons conflict with one another.

On the Add-ons site, there often is some kind of contact information in the left column when you scroll down. For Tampermonkey, if the problem is with a script, you'll need to contact the script author instead.

What specific addons aren't working?

Note that some add-ons might not work properly in Private Browsing mode and on some website that prohibit extensions from injecting JavaScript via CSP rules. One of the websites that do this is the Add-ons website.

You can open the Browser Console and check for error messages

I'm not sure how to know if I have legacy add-ons, that option is not showing up on the add-on manager page anymore. I just uninstalled tunnel bear, tapermonkey and lastpass. they are working right now but they may not work again in a few hours, so i'm not sure if the uninstalling and reinstalling will work

I will contact the developers and see what they would say.

There are a lot of messages about files being blocked by CSP. Mozilla and Github websites are examples of websites that have very strict CSP policies that prevent extensions from working properly like I wrote above. Affected extensions should be working again if you visit other websites. I don't know if there are conflicts between extensions that cause issues like you describe. You can try to disable all extensions and only enable one of the extensions that have problems.
