I’m seeing strange behavior with Firefox (snap) on a default Ubuntu 26.04 install. Spell check keeps trying to force me to use British spellings (-our vs -or, etc). I never noticed this before on Ubuntu. Admittedly I’ve only switched back to Firefox recently. Also of note this doesn’t happen on Fedora.
I did a little investigating thinking maybe Snap needed a separate dictionary package or something but Firefox tells me the EN-US dictionary is installed. I see no options to select EN-US over EN-GB, etc.
I also looked at the source of an It’s Foss community page knowing Abhishek uses British English thinking perhaps there was a language directive in the header. No dice.
I’'ve attached a couple screenshots. The last being Firefox telling me I spelt ‘behavior’ wrong at the beginning of this post.
Somebody tell them folks at Mozilla that we dumped you Brits 250 years ago. We fought a whole war so I can drop the ‘u’ from a few words! They should have a little damn respect. 
I kid, I kid - I know there’s a few EN-GB members here.
