Hello, I'm reporting this issue for the 2nd time in as many days because it appeared to have corrected itself late yesterday, but is back again today. In a nutshell, installing the new Firefox 141.0 update conflicts with the Reddit login procedure making it impossible to do so. Here is the issue as reported yesterday for more detail: https://support.mozilla.org/en-US/questions/1524793 I followed the suggestions I was given, i.e. to try logging in at the Old Reddit site (https://old.reddit.com/r/firefox/) and to disable my Adblock Plus extension, neither of which worked. BTW, I tried logging into Reddit using another browser and it works fine. So I performed another System Restore to eliminate the Firefox 141.0 update, then went into Firefox Settings and disabled "Automatically install updates", and can log into Reddit again with no problem. Firefox is my preferred browser and Reddit is my preferred social media site, so I'll have to stop updating Firefox from this point on unless and until the developers correct the issue, or someone can provide insight into what's causing this and what to do about it. Below are screen shots of the Reddit notices I get when trying to login with the Firefox 141.0 update installed:
