Tops sites will change if I don't update as soon as new version
My settings should not allow any changes to 'Top Sites' yet FF (currently 78.0.2) will change my sties w/o permission. This seems to happen if a new version becomes available and I don't immediately update to it. Should not happen.
How can I solve for this when the settings already should make it impossible? This 'auto change' won't hose my bookmarks, it's relatively minor since it keeps some of my top sites. But it's really odd. I use only uBlock Origin, the rest is plain vanilla.
