Okay, so I made a little progress on the Tor Browser installation.
It turns out, I have firejail installed, and I usually open my browsers (and a few other items) with a special command, e.g., "firejail firefox", etc. Thus, "firejail torbrowser-launcher" ...
When I did this, I managed to get Tor Browser started, running, configured, connecting to internet, visiting web pages, all that good stuff.
Except one thing: With my other browsers, I have them configured to use a Socks5 proxy, 127.0.0.1:9050. But with this Tor Browser, I must configure it to use http/https, 127.0.0.1:8118. Otherwise, I can't connect to internet.
As I understand it, Socks5 is better for some reason that I now forget. If anybody knows better, I am curious what's going on here.
Also, I can get bridges, sort of (they are already built-in), but when I try downloading new bridges, I get hit with a captcha question, but nothing ever appears; no images to click, no characters to enter, or what-not.
So, Tor Browser is sort of working, but I can't get past the configuration. Also, when I try to change my web page colors, fonts, etc., nothing happens. I looked for where Tor Browser calls home in my system, but it's not in the usual folder, i.e., /home/<user name./.mozilla/<mozilla browser>. There is a torbrowser folder in /home/<user name>/.config/torbrowser, but it only contains a json file.
I would do a little self-hacking of about:config, etc., but first, I would like to find where this stuff is kept. I usually make backups before I start messing round.
