Building Firefox isn&#x27;t so easy.<p>There are like 50 build options, any random combination of which is likely to result in build failure, and your only option is to try a combination, wait 10-40 minutes for it to fail, try to diagnose what went wrong and fix it.<p>There&#x27;s also the matter that Linux distro maintainers know more about building than you do, and include things like exploit mitigation, which you&#x27;ll be missing out on.<p>And of course you need to monitor Firefox for security updates, and rebuild every time there&#x27;s an update.<p>It gets boring pretty quickly. Even GNU barely manages to update their IceCat fork.
