Do you have a source for that? I know source tarballs are available at https://vivaldi.com/source/ but I was under the impression that these consist only of the open source parts from upstream (Chromium).

Have you or someone looked through them to confirm they contain all of Vivaldi? Do they state this somewhere? Can you compile Vivaldi from them?

I'm not that concerned with not being able to distribute modified versions (freedom 3) since I am unlikely to have the time to contribute quality code unlike Benjamin above ( https://news.ycombinator.com/item?id=13514415#13517798 )

But I do want to be able to compile it myself and tweak & hack it as I like (freedom 1). (We already have freedom 0 and 2).

Of course I would prefer to have freedom 3 too, so that in case I have the time to do more than hacks I could actually contribute.

I might have answered my own question: https://vivaldi.net/userblogs/entry/a-few-words-about-open-s...

https://github.com/ograycode/vivaldi-source (not-official mirror)

I'll have to try building it from source.
