Hi, out of nowhere my Firefox has stopped loading any pages for the past hour. I have read the existing community articles and cleared all of my history, cache, cookies, and restarted my computer 4 times. Firefox is up to date and was working fine up until I left my computer and returned to it an hour ago. I haven't downloaded anything new or clicked anything weird, I was just listening to a regular podcast this morning. All websites either show up as left-aligned text with no images, or are completely blank. This includes Gmail, Tumblr, Youtube, EyeBuyDirect, etc. All of these sites load perfectly in Edge so the issue is specific to Firefox. Any help is greatly appreciated.

Edit to Update: I turned off my AdBlock extensions one by one to narrow down the issue. The problem was AdBlocker Ultimate. I disabled it and now all my websites in Firefox are working as normal.
