Yesterday i upgraded ff to the current version and since today i experienced problems with a bunch of different sites. Either the cloudflare verification sends me into a loop or i get through and the site's not working correctly. Some others work, though. Disabling add-ons (noscript, ublock) and allowing all cookies didn't help. Most work with microsoft edge, but i don't know if the others worked with edge before.

Does somenone have info on that or experienced the same problem? I'm not sure is it just a coincidence or does the update cause the problems.

Edit:

I found a workaround for some. First i set the cookie block from "all cookies" to "all cross-site cookies", then i allowed via STRG+i to set cookies for the refreshed page. Then i set the cookie block back again.

I assume cloudflare changed the address for some of their cookies which got blocked by ff.

The only one still not working (so far) is suprfit.com. It's not a big shop, their software might produce their own shenanigans. I'll shoot them a mail later.

Edit2:

suprfit.com works now too. Whatever it was got fixed.
