Solarmass I am not sure if it's okay to use Vivaldi sync feature between Snapshot and Stable.
I considered that they might be incompatible, but apparently they're not. At least, they don't seem to be now. At a time when snapshot has added new functionality and new settings, they might be. They both have the same settings, as far as I can tell, and they use the same kind of bookmarks on their speed dial page. There didn't seem to be any negative effects as a result of the sync.
I needed to install LastPass on snapshot, so I could log on to the two racing sites and use my subscriptions on each to access their videos. Default settings on Vivaldi aren't acceptible to me -- for one thing, everything Google is enabled. I always disable it all. Mostly I wanted to sync the speed dial settings.
There's only one Vivaldi sync, not one for stable and one for snapshot. Not even a couple of radio buttons to select the version to sync.
o Vivaldi Stable
o Vivaldi Snapshot
Indeed, I took a chance, but it seemed to work out okay this time.
