Switched yesterday, so far loving it! My objection to Chrome was mostly on principle (anti-Google), so it's nice that there's a performance-based reason to switch to Firefox as well.
Though I just ran into a problem that reminded me of why I stopped using Firefox in the first place: I used xdg-open a lot (in Emacs), and Firefox tries to supplant that whole functionality. It advertises itself as being able to open pretty much every file under the sun, and then prompts you to choose an application to actually use to open the file.
I wasn't asking you, Firefox, I was asking xdg-open.
It's better than it used to -- until a couple of years ago, Firefox altogether had its own awful version of xdg-open; had all the logic to detect file associations, select apps etc.
In any event, you can edit ~/.config/mimeapps.list to fix it up. Hope that helps.
But it is still trying to handle application/octet-stream. Ie, it must have registered itself as a default fallback somewhere, and I can't find where...
Your DE may be at fault as some of them try to do "smart" defaults. xdg-open itself may also be at fault (it's an atrociously bad shell script -- you can take a look at it if you want to debug it).
