Firefox not working

more options

Hi I went to my email provider earlier on and Firefox froze saying that a copy was running and to close - which I did. But Firefox will not access any website: just the normal waiting message.

I did a hard reboot. No joy. I tried a download. No joy. I am using Brave at present to access you. Everyhting else, email etc is working fine.

Any advice please.

Chosen solution

There has been found a temporary workaround(for advanced users only):

Go to "about:config". Search for "network.http.http3.enabled". Set value for "network.http.http3.enabled" to "false". Restart Firefox.

After this bug gets updated, you should set the value back to "true".

OH, BTW Firefox is working perfectly on my laptop (win 10) but my desktop is running Win 7 - could this cause a problem?
