First of all wow, it's frustrating that is it this difficult to report issues and get help with Firefox. That being said, beginning 1/8/2021 every time I try to create a post with images on Facebook, Firefox displays the "a web page is slowing down your browser" error. Waiting does nothing and if I stop it, I can't make the post. I use Facebook heavily for business so this is a MAJOR issue. Clearing the cache, cookies, and site data does NOT fix the issue. I've not had an issue with this before now, and I've been using Firefox for years. I have been using the Facebook container for several months, but this is the first I've had an issue. Is this a Firefox issue, or a Facebook issue? Please help, this issue is getting annoying enough that I have to use a different browser and I don't like doing that.

Thank you

”Webpage is slowing down your browser” This is the new way the browser tells you there is a problem with the script program(s). https://support.mozilla.org/en-US/kb/warning-unresponsive-script?cache=no
