But what's the difference between VimFX and Pentadactyl?

Well, so far, I've found proprietary s/w to be worse-than, the same as and better than open source. It sort of goes case by case, you know.
(But yes, in general, I prefer open-source software.)

Now I do not understand your reasons for changing from Firefox. Are you saying that you switched because the team don't agree on goals and fight and that somehow makes the product, which works fine, work less well?

Seamonkey for daily, Iceweasel or Firefox for shopping and such.

Tor for...well you know Tor stuff. LOL.

No, I'm not. I switched because I cannot support their social policies, policies that clearly go beyond and outside their technical and business mission, which is what I'd be doing if I used Firefox. I also would look for alternatives if they used slave labor.

I disagree with their demonstrated social policies, but I've got no qualms about Firefox as a browser. So I can't complain in a technical forum about it (nor am I calling for any sort of boycott). But that doesn't mean I have to use it, especially if I can find another that, for my purposes, is every bit as good. AmIright?

Sorry, I see now, I can't say I have read much of any companies social policies.

I vote Firefox, but I have been following Vivaldi evolution and it seems to be an important option in near future.

Firefox, the default on LMDE, Iceweasel on Debian. Even though the Debian on my machine doesn't have a DE or a default browser i had to come back to Iceweasel after trying out Chromium, Qupzilla and Midori. The phrases "well-rounded" and "complete" figured somewhere when justifying the choice to myself. It was naive of me to imagine i could make a better one than the developers of most distributions.

Btw, why are Firefox and Iceweasel listed separately, aren't they essentially the same?

I have started to use Vivaldi snapshots.Vivaldi being developped by former Opera people. They will soon come out with an integrated Mail client. This is one thing I love about Opera 12, which I still use for mail. It shouldn't be hard to transfer its content to Vivaldi when its mail client arrives.

Without wanting to open a large can of worms: Yes, they are, essentially, the same thing. However, for reasons of our own, sone of us choose to use Firefox on Debian (there may be people using Iceweasel on other distributions also, I'm not sure) so it's a tough call, really.
As jamison20000e points out above there's an argument that (the)Nightly(build of Firefox), which some of us run, ought to be seperate also. These things are tough to decide.

2 days later and still no answer...

i got interested in this, and soon stumbled upon inox, which seems to me "iridium done right".
archlinux forums thread: https://bbs.archlinux.org/viewtopic.php?id=198763
and a build for archlinux: https://aur.archlinux.org/packages/inox-bin/
what can i say, it runs on my system, the arch forums thread is reassuring.

Very interesting, although it seems to have only binaries for Arch, at least for now! While searching for binaries for it, I have found the ungoogled-chromium browser, which applies the patches from both Iridium and Inox, and adds its own. I haven't tested it, though!

Iridium seems a bit more conservative, like you can install extensions directly from the Chrome Store with it. But honestly, I don't recommend anyone to install extensions from Chrome Store without checking them first. It is pretty common for them to contain spyware.

I either install them from the Opera Extensions Website, because Opera at least checks the code for privacy issues, and forbids extensions to load any external JavaScript, or at least I check for the following when the extension is not available there:
* The description for the extension in the Chrome Store sometimes will mention that it is Open Source, generally with a link to GitHub.
* Always check the permissions requested by extensions before installing.
* Use the extension "Chrome Apps & Extensions Developer Tools" to monitor the behaviour of the extensions for at least some hours, it will show whatever the extension is trying to do in the background.
* The file "manifest.json" contained within the extension directory at ~/.config/chromium/Default/Extensions/ may contain a line called "content_security_policy", which shows whatever external JavaScript the extension loads. I have found a few times extensions trying to load tracking scripts from here.

Mozilla Firefox

oh, not at all (*)! there you go:
https://aur.archlinux.org/packages/inox/
and here are the patches themselves as a github repo:
https://github.com/gcarq/inox-patchset

(*) after compiling for many hours, i gave up on that and thought that even for newer hardware it must be a major strain, so i linked staright to the build.
