This morning, my browser was having problems accessing the pages I use at work. I restarted in Troubleshooting mode, and the problems went away, great. Now I want to figure out which addon / extension caused the problem. The "best" way I've found online is to enable half of them and restart in regular mode, if the problem is gone, then enable half of the remainder, see if the problem is gone, etc. until the problem comes back. This involves a lot of restarting and keeping track of which ones have been tested. What I'd really like is a way to do all this from troubleshooting mode, enabling one addon at a time and testing a certain website until it breaks or I run out of addons, like Git Bisect or similar. Maybe sort the addons in reverse chronological order of addition or update, since the most recently added/updated addons are the most likely to be the problem. This is one of those times where the feature has to be part of the browser, not an addon. :-) Is this already implemented and I just haven't looked hard enough or recognized what I was seeing? Thanks
