Yay! Greasemonkey’s back

I’ve been without the invaluable Greasemonkey for about three weeks and have finally had time to sit down and work through it methodically. All the solutions proposed to create new profiles etc. did not work for me. The only thing that did in the end was remove extensions one by one, restarting each time and adding Greasemonkey and restarting again to see if it got installed. I removed extensions in ascending order of importance, starting with Greasemonkey collections from Lifehacker since obviously they couldn’t be used without Greasemonkey in the first place. I removed; restarted; added Greasemonkey; restarted about five times in total, each time making a note of what extension I removed. The fifth one removed was Distrust, an extension for secure browsing, and that did it. Greasemonkey was installed. I reinstalled the extensions I had removed and all still works well.
