Several locations on the Internet, including the official
Avast forum,
Reddit and Firefox support site
Mozilla Zine, are filling up with user reports that that latest version of Avast deletes Firefox add-ons automatically.
Some users report that add-ons get deleted automatically on startup and without option to prevent this from happening in the first place.
The issue does not seem to be linked to the program's Browser Cleanup tool directly even though it is designed to detect and remove lowly rated plugins and browser extensions that are installed in popular browsers such as Firefox or Internet Explorer.
It is unclear right now what is causing the issue and why only some users of the browser who have Avast installed on their systems are affected by the automatic removal of Firefox add-ons on the system.
