Because not using Chrome or Edge is a must.

It's the least greasy browser that actually works with the modern web.

It's the most customizable, has the most advanced add ons system, syncs well between mobile and PC (though sadly with no tablet app), and it's not part of the Chrome hegemony. Lately it has become faster and faster!

I’ve used it on and off over the years; ever since 2004/2005 or so.

Firebug was amazing for web development back in the days when it was just IE, Firefox & Safari.

I recently built a couple of sites (for a sim racing community) and one of my users mentioned a Firefox bug. I fixed the issue but then realized I need to be more aware of Gecko specific rendering issues. I decided to use Firefox for a week on my iPhone (yes I know, still technically Safari) and my desktop, and I forgot how much I like it.

I also don’t love the choices Chrome has been making recently.

Firefox’s market share is so low lately when compared to Safari and Chrome that it honestly feels like the battle is already lost.

Open source, private, not chrome. Because I've been using it for over a decade.

It's the only browser made for users.

Desktop:

• damn nice
• good Flatpak version playing everything
• all extensions work without weird restrictions
• only Forks that make sense, Librewolf and Tor Browser
• loads of search engines
• arkenfox user.js
• UserChrome.css, in theory, if it was easy to create one. Only SimpleMenuWizard currently to make it less rediculous to use
• also Thunderbird uses Firefox ESR, and its the only good Mail program I know

Mobile

• mull, prehardened
• support for a looot of addons using a custom Addon collection
• offline translations using FF Translations, literally the only app I know that does this and its so damn critical
• dark mode without tracking
• ublock, noscript
• lots of search engines possible
• privacy

I dont use Firefox as it comes on any device, as this is unusable. But with hardening its simply the most secure browser

It's not chrome and it's open-source

On PC:

1. Containers
2. Firefox's screenshot button. It's so good. https://i.imgur.com/9lHxekk.png
3. Wanting to not see the browser market be monopolized. Competition is good.

On Android:

1. Extensions support
2. This button: https://i.imgur.com/heuupxK.png It's so handy.

Been using it for 7-8 years and only seen it improve. A few gripes to deal with, but I'm happy otherwise.

Oh, hell no!

Switched at the mere mention of losing my adblock. Have never looked back (besides when some shitty dev doesn't make their website compatible, looking at you comed)

UBlock Origin

Because it's better in every way?

It's not Chrome, and it does everything I want.

I just think it's neat.

manifest v3

I use it since it's inception 20 years ago. And stuck with ever since. It was one of the first FOSS projects with a mass appeal. In Germany we even had a crowd funded ad campaign in 2004 in that I took part and all that felt very optimistic and cool. And I just always stuck with it and always used it as my main browser. When Chrome took over, Google was already the dystopic mega corp so I was never tempted to use it. Sure I installed it, but hardly ever used it. But I never had big problems regarding speed or resource-hunger. And it keeps improving.

TLDR I'm very nostalgic about FF and will never drop it.

It's not Chrome. Are there really any other good options at this point?

Because fuck Chromium

I just started using it for Android the last month or so when Chrome dropped the flag feature that let you toggle dark mode for websites with system dark mode.

I have a VPN with an adblocker so that aspect of Chrome never bothered me so much. Chrome felt like it worked slightly smoother but at the end of the day a browser is a browser and Firefox does the job. (Samsung's browser is actually surpringly good for those with a Samsung device looking for a Chrome alternative)

Firefox does seem more trustworthy overall, although I've learned by now that trusting tech companies is not a sensible thing to do.

I've just been using it for as long as I can remember, so I guess brand loyalty is one reason. Also, I always get annoyed when I have to use another browser like Edge and Chromium. The last reason is that Mozilla actually advocates for an open web in the organization that develops Internet standards (as I understand it), so I would prefer to give them my tacit support, buy not using browsers from corporations that benefit from me as a users and go against open standards.

Addon support on Android, cross platform sync. I don't need any other reason

It was my first browser. I used IE to download it.

When I changed computers I did use Chrome for a bit. Then Vivaldi because it was better to me (I liked the split window browsing)

Saw mention that Chrome and all related browsers were about to kill adblockers. Returned home to Firefox immediately.

I don’t feel a need to change right now, but have heard of Waterfox and Librewolf as potential forks. They’re in my mind if I ever feel the need.

Privacy and also fuck Google.

Nothing based on Chrome is an option because Google is evil and thinks it can control my computer, Brave customer service literally made fun of me for not liking the way they took over my homepage regularly years ago, Opera is just adware, and Firefox is about all that's left. Even though it's losing more options every update and on mobile it's complete garbage now with everything centered around their homepage so they can try to serve me ads that I can luckily turn off for now.

Bottom tab bar, ublock origin.

I switched to Firefox 2 from Internet Explorer 6. since then haven't used anything else.

gave some chances to other browsers like Chrome or Opera, but didn't like any of them.

as for why... no idea. Mozilla was always appealing to me and their browser is just on point everytime. and I also like red pandas.

because its not chromium

I tried Firefox but it was hot garbage on Android.

Ended up going with Kiwi - same extension support but just better designed and much faster. Firefox kinda sucks on mobile beyond ublock origin support.

I like it and I don't like google

I have been using Firefox ever since. Never really had a reason to switch to something else.

It was the only real place for NoScript for a while and I haven't found a better whitelist add-on. A lot of it is inertia at this point. I avoid Google as much as possible anyway, so Chrome isn't an option.

Web extension manifest v2 ublock origin

Because best

Why not?

Why do you use Chrome?

Add-ons on mobile. Plus, Chrome is slowly but surely gimping their ad-blocking extensions.

I initially switched because I felt like it had better support for linux and specifically wayland. Then stayed for other features that are mostly mentioned in other comments.

My wife says: we use firefox

And i cant think of a reason not to.. so of course ive installed Librewolf

I switched from Netscape Navigator to Firefox and have used it since. Have tried other browsers but they can't compete.

It’s a huge improvement over Mosaic.

Not Chromium, has custom CSS for the GUI, is open source software and it has a nice extension library

Also it's also a pretty good browser (right now I'm technically not using Firefox, but rather Librewolf, but still based on Firefox)

Because I need to browse the web.
