Hi there, I have been using Firefox since a long time with these extensions. Do you think if any of those are redundant? Why I ask this is that while using Outlook in Firefox, it's consuming around 1.7 GB of RAM. I don't think it should be using this much amount of RAM for just a single tab of Outlook. Edit: I already use uBlock Origin, but it's not present in the attached pic.
You could try disabling some extensions to see if there's a troublemaker. Alternatively, run Firefox in safe mode to see if it's your settings/extensions or the site itself
