An Adblock script is slowing down Firefox

[Marco888]

It offers *disable on this page*, but is shown so quickly that I almost never have a chance to click YES.
No clue which script.
Was getting the error A website is slowing down Firefox, but this is more specific (and in Safe Mode it didn't stop).


Firefox 84.0.3
ABP 3.10.1
Easy List
Easy Privacy
Fanboy Social Block

This has been an issue on and off for a while.
When persistent, it is so annoying I just leave the website.

Cannot find an answer anywhere.

Thank you.

What script? What site? rules#participation

My mind reading device must be on the fritz again.

The header says, An Adblock script is slowing down Firefox.

This is on Wunderground, Outlook.com, Facebook, Twitter, OneOpinion.

Fontawesome is one.
This is from Outlook - verbatim error: moz-extension://828d9f18-fde6-…ba8d22a8365/include.preload.js:1496629220

My apologies.

I recommend switching to uBlock Origin instead. It's faster, so it's less likely to produce this kind of error message.
