Thanks for making it open source. But it's not working. "Failed to fetch one subtitle" error. I wanted to use it to translate from English to Turkish.

I love the extension. It completely improves the YT experience.
I'd tried other options, and they didn't work quite right.

Does not work at all in Firefox for Android. Also the name of the addon has a misspelled word.

mein tag ist gerettet danke danke

no function

I don't show its Settings Icon ....
Tested on:
Firefox Quantum and Warefox Classic

just working

It works.
would be better if the subtitle can be movable or editable
