I love this addon WHEN it doesn't correct my British English spellings into American ones. I've read your instruction - there is no English "(no variant)" in settings, and selecting "British English" in "Interpret English as:" doesn't stop the addon from correcting my British spellings. This has to be a bug.

Ich bin echt begeistert wie gut es funktioniert! Toll und eine wahre Freude! 😘

Actually works even on android

Mostly decent, but British English is not listed as a mother tongue or preferred language, so I was constantly get 'corrections' from British English to American.
I CANNOT have English 'no variant' as ONLY option shows US flag for both mother tongue and preferred language. The only place where English British is available is variants which doesn't seem to ever come into play when I was using this as it only ever flagged up British spellings wanting to change them to American.
I'd post screenshots but i cant seem to be able to.

Macht einen sehr guten Eindruck.

Fabulous extension. Works in many situations. Hours of fun. Highly recommended.

Edit: It didn't detect a single grammar mistake in these test sentences:
"Me typing sentences with the worst grammar for demonstration purposes"
"Me like drink banana smoothies"
"Me confused as to why LanguageTool not detecting simple grammar mistake like these"

Must have - und ich habe nur wenige Tools instaliert. Das hilft mir beim Texten von Webseiten und Post wirklich weiter. Cool und Danke

классное расширение, очень помогает в работе
