I tried running FF136 and it would not load any website for over 9mins,
restarted FF safe mode, same no load
tried loading http:// sites same
network checks as other browsers work
after several restarts of FF and waiting FF now loads pages.

What would be causing this?
machine load was not high

I have seen this before on some other versions of firefox and it has been cache / settings causing it. In all cases, I saved the profile information ( bookmarks, passwords, settings etc), and then did a refresh and it was all good.

In a couple of cases I had to clear cache and all data, and then reload the data I had saved.

This new version of Firefox has two VERY different things Side tabs and a change to how it caches.
