Around a week or two ago, Windows Defender has begun flagging files within Firefox as trojan's. It happens only when I use the browser, sometimes immediately, sometimes after a few minutes. I tried disabling my extensions and reinstalling, but the pop ups continue.

Is it safe to assume this is a problem with Windows Defender? Image of the detections attached.

We regularly see problems with Windows Defender reported about files in the Firefox disk cache (cache2 folder), those are likely false positives as this folder is only used to store

I followed the steps in the article to clear the cache but the notifications continue to pop up. If those files are being flagged, does that mean there is a malicious file in Firefox somewhere or I went somewhere unsafe? If they’re false positives that’s fine, I just want to be sure before I decide on whether or not I should whitelist this folder.
