So, I’ve been playing around with Vivaldi a bit now, and I have to say, it’s not that bad. The only thing that bothers me is the fact that it’s closed source. I still have a few questions for the Vivaldi users among us:
What add-ons do you use?
Okay, it’s just one question, but a pretty important one I think 
I use the following extensions:
Dark Reader
Push Go
YTBlock (for hiding content by keyword)
YouTube Blocker (for hiding YT features)
uBlock Origin Lite
Thanks 
I don’t know what “push go” could be good for me, but I use the rest of them, too.
Push Go is an extension for using PushBullet (SMS/notifications mirroring from smartphones). I have pretty much given up on KDE Connect, just too buggy.
The two I’ve used with success for quite some time are:
I share your discomfort with a (supposedly small) portion of Vivaldi being closed source. But I’ve generally enjoyed using it enough - and feel I can trust the Vivaldi team - that I hold my nose on this one.
It being installed from the extra repository also gives me some kind of comfort.
One of the native features I’ve come to use extensively are the workspaces… of which I’ve got six in regular use.
If librewolf allowed me to do the same I’d seriously explore it as an alternative due to its being truly open source.
That’s right. The Workspaces feature is incredible. I also use Cookie Guardian to delete cookies when I close the browser. That way, when I close the browser, I can keep the cookies from sites that I’ve recently visited.
I’ll probably keep Firefox as my default browser and use it to access sites that require me to log in.

Love Workspaces. Also love being able to hibernate all background tabs, makes a huge difference on RAM usage.
Milking this feature a bit further, I’ve got a slick little bluetooth button push controller (which has LED labeling of text) and I’ve mapped the Vivaldi workspace selection keystrokes to each of these 6 buttons.
Looks like this …
Again, if I could take this self-groomed UI over to librewolf, I’d be exploring a switch. But so far at least, no obvious way to assign things - perhaps I need to delve deeper into what librewolf can be taught to do.
Vivaldi has a builtin setting for dark-mode. I’m not using Vivaldi but I know it’s there as I’ve used it before when on Vivaldi.
That’s true. But it doesn’t work nearly as well as the Dark Reader add-on. The page is dark, but the right and left sides of the background remain white. And that’s exactly where Dark Reader comes in. The entire page is in dark mode.
Interesting. I’m not seeing white side sections and while I have dark mode selected at all times I do not have Dark Reader installed. I’ve used it on Firefox but saw no need on Vivaldi. 
(This is the case on three different monitor types, so perhaps you’ve got a monitor config issue going on?)
I saw it that way on a few pages yesterday. Not on all of them… I don’t know enough to pinpoint exactly what’s causing it.
Yep, and it’s completely themeable. I actually use light themes on all of my websites, including this one, and my Dark Reader theme makes the colors uniform.
I found this useful:
This is my workspaces, with icons.
Yes, Thank you! This is very useful. It seems to me Vivaldi has endless possibilities when it becomes a theming and workspace thing
