Dev channel update to 93.0.946.1 is live

Still no sign in Canary and Dev of an acceptable, useable UI for left and right clicking on many more extension buttons than will fit in the toolbar. I presume we will be losing the very acceptable and useable UI for that from Stable soon, to be replaced by the Extensions button that is awful for that with e.g. 20 more extensions than will fit in the toolbar, at which point I'll be giving up on you, uninstalling all Edges from laptop and phone, and will stop bothering you having given up on this software in which the rush of shinny bells and whistles cannot make up for something that to me is a very basic UI issue.
