That lack of capability prevents it from being my daily driver, even if the rest were good enough (I’m not saying it isn’t, I’m saying I have no reason to find out).
I am certain I have inadvertently pushed many people away from Firefox for that reason alone, because when they ask for me to add Firefox support for my tools, I have to tell them it’s impossible.
I have tried to talk to Firefox developers about that a few times, at open-source conferences and such, but they think AppleScript is some power-user feature and fail (refuse?) to understand power users drive adoption and create tools that regular users rely on.
I remember whenever a Firefox story was submitted on HN, multiple people commented “I want to use Firefox but it’s missing <whatever>”. Then Mozilla started doing a lot of questionable stuff (all of which they eventually abandoned) outside their core competency and even pulling distasteful marketing stunts, and at some point people started commenting even that. I presume many got tired and gave up on Firefox entirely. I almost have. I now root for them only conceptually, because browser diversity is good.
I also noticed that no matter how politely someone pointed out on HN “Firefox doesn’t fit for me because of <whatever>”, they always got downvoted. If valid polite criticism is buried, no wonder things stay the way they are.
- Change to first browser tab whose URL or title matches <whatever>.
- Close every browser tab matching <whatever>.
- Grab all your tabs and backup their URLs to a file.
- Join all tabs from all windows into a single window.
- Execute JavaScript on a page and get results back.
- Grab the URL of the current tab and open it in a different browser in a Private window.
- And many more things.
