Firefox will not load any websites, it’s like there is some kind of connection issue. My network is fine, other browsers work fine, but Firefox seems to be ‘stuck’. I tried some of the recommendations like the ipv6 config, and DNS prefetching. No viruses came up on scans. I am using version 137.0.2 On MacOS 10.15.7. I also think the problem might be that it seems to be constantly checking for updates and there is no way to stop it. I deselected the ‘automatically install updates’ option, but it’s still spinning as it checks for updates and there appears to be no way to stop it.
