I'm at a loss here, problem is in subject line. This has happened for a long while and has persisted through various versions, I have attempted to:

- Alter my antivirus and internet protection settings to allow as much traffic as I can. - Download addons as XPInstall files and try and use the File -> Open File option in the Menu Bar - only returns a line about not having permission, despite having Admin permission.

My Firefox Version is the current 118.0.2 (see: attached image).

Thanks in advance.

Can you open this file, for instance in 7-zip?

It is possible that your security software opened the file for inspection and broke the signing. What security software do you have?

It is possible that (anti-virus) security software is causing the problem. Try to disable security software temporarily to see if that makes a difference.

I use ESET, but Windows Defender is also present on my system.

I paused my Antivirus and antispyware, option in the setup tab of the application, then tried to:

- Use the normal add to firefox button -> returns same error as in title. - Download and File Open another copy (downloaded while my antivirus was off) of u-block -> returned the same "Admin Permissions" line.
