Good news: It's possible to install Firefox in the ChromeOS Linux development environment using the regular Debian apt commands now, not just with Flatpak.
Bad news: It's a straightforward yet daunting task straight out of a '90s Linux hacking guide. https://support.mozilla.org/en-US/kb/run-firefox-chromeos
Other news: No matter which way it's installed, Firefox 148 on ChromeOS 144 is so unstable that it crashes unpredictably within a few seconds to a few minutes.
I'm weighing options for a Chromebook browser that's generally decent and doesn't actively sabotage good ad blocking like Google does.
So help me, one of the options I'm considering is Microslop Edge.
Mozilla's instructions for installing #Firefox on ChromeOS don't mention Firefox ESR.
I forgot that this kind of ESR was an option.
`sudo apt-get install firefox-esr` works just as well as `sudo apt-get install firefox` does. Today, it installed Firefox ESR 140.8, and it seems as stable as 148 should've been.
After a dozen years of happily perusing the Web using browsers with decent ad blockers installed, just 15 _minutes_ of trying to find stuff with Google Chrome feels like a dystopian television nightmare. Like, any second now, Google will save me from the sea of animated overlay ads by happily letting some random malvertizer show me a full-screen error message telling me to call Windows Support at 1-800-FLEECE-ME urgently.
