every time I click on a forum link it takes ages and I get this warning from the browser, wondering if it is only my problem or other users are seeing the same

All good on my PC

I used to get that warning on my old computer but I thought it was Facebook causing it (both it and Seebreeze were usually open at the same time). The computer was using an old J3 chip that was working near it's limits. I haven't got it since I upgraded my computer

seems a problem with Firefox, works well in Chrome

I have no problem with firefox, but I do have a few urls blocked with "no script" and "ublock"

been getting the same on firefox since yesterday. with no other pages open, weird....

I just alowed everything through in ublock, and no script is only blocking goodgleanalytics. still no warning messages. I have firefox 81.0, it's what comes with linux mint 20, so could be a slightly different version to a windows based one.

Firefox 81.0 on Windows 7 on a 7 year old laptop is working just fine.
