> Complaining that Firefox provides development tools when all major browsers also ship with those it's simply absurd. No it is not, and here is why. 1. How many developers work on Firefox? Chrome & Chrome or Webkit-based browsers are already some 95% of the market. Citation: https://gs.statcounter.com/browser-market-share It is borderline irresponsible to work on Firefox now. Test on it, yes. Develop on it, no. 2. There is already a developer edition: https://www.mozilla.org/en-US/firefox/developer/ I am just arguing that more functionality needs to be moved to that from the ordinary mass-market edition. > So is complaining about lack of an integrated adblock when Firefox was the one who created that feature and allowed any third party to roll their own. No it isn't. It's a feature of competing products. I am arguing Firefox should be th

e power users' tool. So replicate the key functions the competition have. > Whining about vague complains about profile handling Dude, if you don't understand it that doesn't mean it's vague. When the Mozilla suite was developed, the main Windows OS was Windows 95, which did not come with a browser. IE was not only an add-on it was a paid-for extra. Now the OS provides profiles and functional separation. Lean on it, make the default edition as small and as fast as possible. Less is more. > And the peak of absurdity is complaining that Firefox is customizable Again, ISTM you don't understand me. I am saying it's still more customisable than Chrome and they should lean in to this. Don't make it necessary to frig `about:config` and add a config file to move a freakin' toolbar. This is not a hard point. > and allows you to do stuff no one in the world cares about. So you don't know how to customise your browser. I do. I care. I did my research. E.g. citing the Classic Addons Archive: « 19,450 Firefox add-ons created by 14,274 developers » https://github.com/JustOff/ca-archive A lot of people care a lot. 15,000 developers falsifies your ludicrous "no one in the world cares about. Like many others, you are mixing up "I don't care" with "nobody cares", and you are wrong.
In Ask HN: How can we help Firefox not to dissapear?
Normally I'd say "you must be kidding" but I've learned that people here often don't know stuff that seems very obvious. The big change for millions of us was Firefox Quantum, which came out in November 2017. https://wiki.mozilla.org/Quantum Mozilla is proud of this because it involves some Rust stuff, but it was a massive loss for the extensions world. It removed (or disabled) XUL, Netscape's extensions language: https://en.wikipedia.org/wiki/XUL To quote from the Classic Addons Archive: « This catalog contains 93,598 versions of 19,450 Firefox add-ons created by 14,274 developers over the past 15 years using XUL/XPCOM technology before Mozilla decided to ruin the classic extensions ecosystem and go exclusively to WebExtensions. » https://github.com/JustOff/ca-archive For me, before Firefox 57, it worked superbly for me. Afterwards, of m

y 13 essential addons, only 2 still worked and one of those was trivial and unimportant. It destroyed my browser and drove me away from using Firefox after nearly 20 years, dozens of computers and ½ dozen different operating systems. Other cut functionality: The best cross-platform FOSS email client, by far, is Mozilla Thunderbird. Mozilla has repeatedly tried to kill it. https://www.theregister.com/2020/01/30/mozilla_thunderbird_h... Mozilla also has cut off Seamonkey, the original Mozilla Internet Suite. https://www.seamonkey-project.org/ Mozilla code is the one remaining FOSS WYSIWYG HTML editor, as included in Seamonkey. It threw it out. So far the following forks tried to maintain it: Kompozer: https://sourceforge.net/projects/kompozer/ NVu: http://www.nvu.com/ BlueGriffon: http://bluegriffon.org/ Mozilla has no real idea why people use Firefox or what they want. It has forced wildly unpopular new features on people, such as the Australis theme. https://support.mozilla.org/en-US/questions/974802 It's forced telemetry that kicked the entire browser offline for millions: https://www.theregister.com/2022/01/18/foxstuck_firefox_brow... And yet it includes a huge complicated "developer mode" that 99.9% of users never want and never see. Mozilla's Boot2Gecko became FirefoxOS which became KaiOS, the fastest-growing mobile OS in the world. https://www.kaiostech.com/ Mozilla abandoned FirefoxOS. KaiOS is proprietary. Mozilla licensing should make that illegal. Is Mozilla enforcing it? No. Who wrote the license? Mozilla CEO Mitch Baker. Salary: $3 million in 2020. Also 2020: Mozilla fired 250 people, quarter of its workforce. https://www.theregister.com/2020/08/11/mozilla_staff_layoffs... Summary – cut functionality from Mozilla products this century: • XUL extensions • Email, both integrated and standalone client • Newsgroup reading • FTP support • XMPP Chat • Web editing • Native FOSS mobile OS • Multiple themes. And so on.
