Since the update to version 85, Firefox (for Mac) will no longer allow me to post to Tumblr. When I click the link to start a post, the three-block animation will pop up on the screen and then it hangs for about 10 seconds. Then it gives an error asking me to try again. I've tried turning off my firewall, all add blockers, and add-ons. The only add-ons I can think as possibly being the culprits are Ghostery and AdBlocker Ultimate. Turning them off and restarting Firefox doesn't fix the problem. I also turned off Little Snitch and that also didn't fix the problem. Has anyone else had this problem? Any idea what might be causing this to happen?
