So I've been through a rough past few days with Vivaldi. Thursday night it slowed to a stop, so I closed it. When I booted back up, it loaded none of my saved tabs. I couldn't get them back any way, so I reinstalled it and reloaded as my tabs asci could from memory.

Only problem is when I shut it down after that, it wouldn't boot back up. And it also won't install updates, which I tried, hoping an update would fix what's broken. So I've been trying to find a way to get my browser to boot up for hours, and I'm about ready to back up my profile from one or both, delete everything and reinstall. And then load my backed up profile. Will that work? Is there something else I should try first?
