Switching from Beta to Release?
How do I move my settings? Beta has been too unstable for me lately. I've been getting crashes when moving tabs from one window to another. Before the crash, if the tab I'm dragging hits the new tab button, it changes the tab's appearance from the original to a new tab and placing the tab down in the tray instantly causes a crash.
I've also been frequently losing response from the browser. Tabs will randomly stop loading or processing the addresses I type.
You can just install the final over the Snapshot version, but they are different channels, so Check for Updates won't find any new versions until 1.9 is released.
You might need to Clean your Profile
If you use current Snapshot 1.8, moving to latest stable 1.8 won't cause any problems. They still same Chromium version. Vivaldi only raise Vivaldi version for latest stable.
But those crash, if you use extensions, better check which one cause it.
If still fail, yeah, try clean Vivaldi profile.
