When I get onto the FOC-U forums, I use the
https://foc-u.co.uk/index.php?action=forum as my book mark in Firefox.
I then centre click on the forums which are of interest to me to open them in new tabs, switch to the new tabs and centre click again to open the topics in their own tabs.
However recently, instead of the page coming up with eg "The Covid Thread" in the title and showing the topic posts, they've just been coming up with a blank page and the URL in the address bar.
I've tried reloading, clearing cache and cookies, switching off uBlock Origin and NoScript but nothing seems to fix it, so eventually I have to go to a different site (eg another forum) and do some stuff on there, then, when I come back, FOC-U tends to work properly again.
Has anyone else had issues like this?
