I want keybindings in Firefox that mirror the ones I set up in Emacs and kitty. An Ubuntu specific solution is welcome (I stick to the latest LTS releases) but anything will do.
A link to another question about emacs keybindings showed up when I was reviewing this question, but the answers seem outdated (the GitHub repo for FiremacsWE, replacing Firemacs, is labeled incomplete as of its last update, 5 years ago).
Writing a Firefox extension is one option, but is there a simpler way to customize Firefox keybindings?
