Which Web Browser do you use?

I use Firefox because it offers the ability to sync a complete history, bookmarks, tabs across desktop and mobile. No other *nix browser has this feature save for spyware Chrome and Chromium.

I wish the performance were better though. It sucks on lower-end now. Have to turn off JS on one of my laptops (only 4GB of memory) because it's so bloated. Firefox takes up about 8 times as much memory for pages compared to Brave or other Blink-based browsers.

I've also heard webkit is a tad outdated and has certain vulnerabilities which still haven't been patched

That's the historical situation, they had problems stabilizing. webkit-gtk in pkgsrc is quite well maintained.

qt5-qtwebkit is a different story, unfortunately. Upstream decided to discontinue it in favour of webengine, based on non-portable chrome engine, etc etc. Recently picked up because a few companies were still relying on it, but there's only so much that can be done.

I typically try to get updates out for firefox68 within a day

I use Firefox for everything (including web development) unless some application requires Chromium (only Microsoft's: Skype, Teams) and I'm required to use that application.

Firefox provides a good user experience on all web sites and applications and I need its developer tools, so a low end browser with limited features wouldn't do.

I don't use Chromium unless required to do so because I find its user interface choices confusing and not very convenient. Moreover, I find it a bit too inquisitive.

Furthermore, only Firefox and Chromium allow a normal use of web-based videoconferencing solutions (e.g. sound does not work on Safari and the previous generation of Edge). I privilege the use of these solutions over those requiring the installation of bloatware on my machine - which anyway is never provided for any BSD OS.

Simply stated, without Firefox, I would be unemployed.

Still looking, but for now otter-browser and netsurf-gtk on OpenBSD.
Firefox on all other devices (if Windows or Linux) plus many other lightweight ones on Android.

I'd like to try some webkit ones when time.

Oh, I also use elinks for text-browsing and really wanna learn to operate edbrowse since I use the standard editor preferably - and it's supposed to be exceptional for scripting (it includes js).
