So at work, my Firefox got automatically updated to 57.0 (Quantum) since I have automatic updates enabled.
Turns out that a lot of add-ons don't work anymore with 57.0, e.g. the session manager and the tab group add-on which I use extensively. It seems that I lost all but the current tab group which I'm not very happy about...
Now, at home I use the same add-ons and I'd like to prevent losing my tab groups so I'm looking for a way to disable automatic updates (which are enabled) before I start Firefox so that I get a chance to save/export my tab groups and find a solution that will work with 57.0 before actually updating to 57.0.
How can I do that?
