My biggest complaints with my switch is 1) no Chromecast functionality on Youtube and many other supported video platforms, 2) Very minimal page/text translation services (Arabic is missing), and 3) no search or translate from image (google lens) which I have gotten pretty used to. Oh and also, seeking videos is weird on FF, the mouse goes way past the scrubber when fast-forwarding or rewinding, just seems weird..
Add-on replacements:
- Linguist for translations.
- Search by Image for reverse image search (there are others that just use Google Lens directly, but I use this one).
Cast is a bit more cumbersome. There is fx_cast on GitHub, but it requires a companion app. Firefox seems to want to add cast based on a flag you used to be able to enable, but I'm guessing there are some restrictions from Google's end they ran into.
