doesn't this bug only manifest itself if one is using microsoft defender as their only security solution, and not a 3rd party AV/IS? if so, then the number of Firefox users in this calculation is much lower.
I don't know if that's the case. I'm a Firefox user but consider all the 3rd party apps nearly as much malware as the things they are trying to solve. I run strictly defender and try to make good choices when downloading and browsing.
I actually replace Defender with a 3rd party choice (Eset) for this very same reason - to wrestle some control over my OS from Microsoft. I find Defender to be overbearing in so many ways.
well, if we're taking strictly subjective personal experiences as some sort of a relevant benchmark, then I'm a Windows Firefox user that has never used MS defender for any length of time, and always strictly a reliable low-impact 3rd party AV like ESET or Emsisoft. so I guess the two of us cancel each other out.
More complicated still, defender does not completely stop working when 3rd party AV is installed. Also maybe Firefox is not the only app triggering this bug?
