Constant Network Error and Reconnecting messages on Firefox

Hi all, I expect this is a Firefox issue but hoped somebody here might know how to fix settings to solve the issue - which is constant Network Error and Reconnecting messages, which mean I can browse but not play at all.

Lichess seems fine on Chrome, but I'd still like to fix it on Firefox if possible. And this is only on my computer in my office - at home, on my laptop, Lichess works fine on Firefox.

Anybody else with the same issue, or ideas on how to fix it?

Hello!

I had this problem all of yesterday.

Today. I do not have this, so it may sporadic thing that happens.

Maybe try updating Flashplugin?

Good luck!

I tried this, but it doesn't make any difference. Very strange that it works on Firefox on one computer, but not on Firefox on another.
