1.11.901.3 - what happened?
Updated to 1.11.901.3, vivaldi taking ages to start, even with extensions disabled and it currently has 4 tabs open and is using 1.5 GB of memory and climbing. Tab thumbs had disappeared when it did finally start and it had switched my settings back to opening with previous session.
Think I'll have to head back to Firefox.
