Unfortunately Tor browser has some dbus stuff as compile time dependency; sadly also pulse...
Ah, but that's necessary! Took me a while to more fully understand what Wanter Dnes wrote in some of the links (or second links from those, second maximum): compile time is fine with Tor browser! Because it later accomodates, it has to!, both pulse-system and non-pulse systems, as well as dbus-systems and non-dbus systems!
Well, I mean caught with my uncenz script (must still be: https://github.com/miroR/uncenz and that's way better than just camera, i.e. screencast, because it's also complete network session recorded, with SSL-keys to unlock it!).
Need to post it, and I'll try very hard to do it soon, because it involves Pale Moon very much too! This time it involves even Micro$oft. Preview-in-words: links that are perfectly correctly written and saved in a Github page (bought by M$ very recently) confirmed not to work (work = open, in Pale Moon browser), and after a few more seconds, they work again.
The analysis (it really really doesn't fit on a forum, and being safe and secure from this kind of "failures" is why I build/run Pale Moon and not Firefox or, God forbid: Chrome) is to appear on: https://www.croatiafidelis.hr/foss/cap/ ... -and-seek/ (non-extant at the time of posting this).
