It’s a huge improvement over Mosaic.

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.

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.

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)

Principle.

To counter a monopoly

Because it appeals to furries.

fast, no web environment integrity, not run by a tech giant, no anticonsumer changes, NO CHROMIUM, goog wayland support

good privacy

Because Chrome kept crashing my GPU driver, and Firefox doesn't.

And I used Chrome in the first place because Firefox let malware onto my Windows XP PC. Chrome updated add-ons automatically at that time, and Firefox didn't (not extensions, we're talking things like Macromedia Flash, Shockwave and Java Applets that are long dead now).

I use firefox because Lemmy told me to.

I personally don't use Firefox as anything except a spare whenever a page doesn't load right in Vivaldi. Not only because I strongly dislike the way Mozilla itself is run (I'm not even going to get into their financial records) but also because of it's glacial development speed. Mozilla does pave the road in some ways with stuff like mobile extensions and an unprecedented amount privacy features. But it still takes them forever to do some of the most basic stuff. Still no native PWA's, Passkeys are still under development. It mildly feels understandable why people don't feel like testing with Firefox as much as they used to.

Even cutting Google's monopoly over the internet out of the equation, Firefox still doesn't feel that good. Sure, it might be the fastest browser on the market at the moment. But for a company being paid 450k for a search engine deal by the very thing that Firefox users hate, what gives with the amount of ads engrained in search and bookmarks, the occasional popups for Mozilla VPN/ FF Relay. And yes, I know you can turn them off, but it's ridiculous that a FOSS product even has them to begin with. Also how difficult it feels to be involved in the development of all Firefox products over on Mozilla Connect + Bugzilla + GitHub.

I have nothing against gecko based browsers, but until I see something truly stunning, I don't really want to bother. I know Librewolf exists and solves some of the problems with modern Firefox (also being even more hardened than Firefox), but given Librewolf is also a hobby project that deliberately doesn't accept donations nor even provide an auto update mechanism on macOS (the main system I use, in combination with my pixel devices), the bus factor is too strong for me to consider.

It is the only one that can hold my hundreds of tabs. It's also ooensource, but that's a bonus. Recently addblocker is a very good feature too.

Desktop: Google done fucked up. I didnt use FF cause of one of my extensions but I opted out when they started talking about the DRM for webpages.
Mobile: Its just better with Adblock.

I think foxes are cool :)

I started out with using it on the mobile, due to the add-ons being suported, but then Google starten messing around with chrome, announcing changes to the plugin api that would neuter Adblockers and now, the DRM for the web thingy, and I thought enough is enough.

Firefox still has its issues and Chrome does feel more polished, but I'm going with the good guys on this one.

Its good enough now and mobile addons exist, plus fuck chrome

I am slowly switching back to Firefox since Google are nerfing ad blockers in Chromium. I'm switching to DuckDuckGo since their search results have become almost unusably bad recently. Unfortunately though, there it's no usuable replacements for the rest of the Google ecosystem as far as my use case is concerned. I'd even ditch Android if there were a reasonable alternative.

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.

Tree style tabs in what made me switch to Firefox.

I like that it's not Chrome, and that it's so modifiable.

Also, Edge was using over 2 GB of RAM on my work computer with only one tab open.

Because best

1. It's FOSS
2. Manifest v3
3. AdBlocking extensions for my mobile too!!!
4. They created Rust my all time favourite programming language.

Many reasons, but the main one is being able to self-host the sync server. It's just crazy that the entire browsing history of most people on the internet is stored on Google servers, with no e2e encryption!

Containers addon. And it has bookmarks decades old. Remove both and I wouldn't care much. I'm also more familiar with it. It feels more natural due to this. I feel more comfortable on it. More at home, less scared.

Because I need a browser.

I like Lynx

Works good at browser

I don't like Chromium, on mobile it has extension support.

I like that LibreWolf automatically clears history upon closing.

Because at the time I started using it, it was still Mozilla and the other alternative was Internet Explorer, the browser from Microsoft - the Evil Empire of that time - which was riddled with security holes (the whole ActiveX stuff, especially, was a complete total mess).

Later Chrome became more fashionable but to me it was already obvious that Google's "Do No Evil" slogal was complete total bollocks (plus it came out in the Snowden revelations how Google was used for civil society surveillance, plus by then they had become mainly an Ad Company with a search engine, hence anti-privacy) and I wasn't about to trust what already back then looked like the up and coming New Evil Empire with access to my computer and browsing habits.

Mind you, I did use Chrome on my Android devices, but that was because I expected the OS itself to be rigged like crazy for privacy intrusion and worse so avoiding Chrome there did very little to reduce my privacy exposure in there, though eventually I moved to Firefox there too.

Because I can.

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.

The tree-style tabs extension

It's the best
