Are they the most privacy respecting? no.

are they privacy respecting ENOUGH? sure

For add-ons, mostly. I use Tree-Style Tabs and can't live without it at this point.

I was shown it by a mate, along with soulseek, in like, 2006 or so when in sixth form. It was way better than what I was using at the time (IE)

At least that's what I remember, pretty sure that was the date. I remember soulseek was before by a bit actually as we used it for trading At the Drive In and Mars Volta tracks

I've carried on using it because of plugins, adblocks, privacy, etc.

I can't find any reason to use an alternative browser

Privacy, real ad-blocking, and fighting for the open web. Also, actually being free software.

Because I never particularly liked the alternatives.

When someone built a form that for some reasons doesn’t work with Safari. Or when watching streaming sites with pop ups (FF full screen is really nice in the recent update).

I’d use it more, but I rely on iCloud password management built into safari across my family’s devices and handoff/tab groups to manage tabs across them.

Cause it's the Red Panda browser, cuddly creatures🥰

Honestly, when I got my first Ubuntu install disk and got everything up and running, it was the default browser. I just never looked back.

Trust. I think it has been earned - so far. NCSA Mosaic was my second browser, and while I've experimented with all the major browsers and many not-so-major contenders over the interim couple of decades, Firefox has been a constant for me ever since it was first spawned off of Mozilla. I still believe the Firefox team when they say things, and so far that has worked out just fine.

Ctrl+Tab cycles to previous active tab and is actually useful.

Vivaldi is my main browser of choice but Firefox is my backup. I'm logged into both and have sync enabled and have them installed on Linux and my Android.

If a site doesn't work on Vivaldi, I'll try it on FF.

I don't use Firefox.

Nowadays, a "freedom-respecting" and/or a "privacy-respecting" browser became a myth. Even so, a buzzword. If you believe theres such browser, you are delusional.
