I-Firefox Isithangami Sokwesekwa

Firefox updated to 97.0 (64-bit) this morning for me and immediately ceased functioning. It could not even load about:addons or about:settings. Other browsers worked fine, and by processes of elimination I found it to be Webroot that was causing the dysfunction. I've already opened a support ticket with Webroot, but I wanted to make Mozilla aware of this conflict and to ask if there is anything that I can do to remedy this besides completely disabling my anti-virus/spyware to use Firefox?

yesterday firefox worked fine. Today when I opened it, it was slow loading my homepage (my email account) and would open new windows but never open anything in them. It would open new windows from links in an email. It would give no error messages and there was no spinning circle or anything else to indicate that it was working. When I typed in an address and entered, nothing happened. I tried the refresh, but that window wouldn't open. I did a reinstall and now my home page won't even come up. I have an Alienware x17 R1 running Windows 10. Other browsers (Microsoft Edge, Opera) run fine.
