I think that this has happened after a boot up, if I have left it for awhile and I hit T'bird and Vivaldi  one after the other to bring them up.

Any thoughts on where I should look to track this problem?

I am tempted to bleachbit the computer, or to replace Vivaldi with Opera on the offchance that Vivaldi is the cause.
