About a month or so ago I started having problems with the addon and getting this message:

'An issue has caused your ABP settings to be reset to default. Fix the issue and learn more."

It is unclear what the "issue" is and there is no info about it or what to "fix" and this is creating problems (a new tab about it every time I open FF 78) and it no longer functions as it used to.

PLEASE fix this! I don't want to look for a new Ad Blocker. I have disabled this temporarily (THAT'S not useful!) and hope to hear from SOMEONE very soon or I must delete it and start searching for a different add-on.
