It's too slow. Is there a way to speed it up? I type my entire text/comment and it takes 5-10 seconds AFTER that to start showing the wrongly spelled words.

The red squiggly lines should appear IMMEDIATELY the moment I've made a spelling error. Grammatical ones can take time. But because of its slow speed I hardly ever notice my mistakes until I've posted my comment

good

I bought it for Overleaf, but they broke the compatibility and won't fix it.

Great alternative to Grammly and its free 👍

Après un premier test en français cela à l'air de fonctionner sur toute sorte de faute. On verra dans le temps.

Foi uma grata surpresa este novo corretor ortográfico integrado ao Firefox, as correções sugeridas a nível de ortografia, concordância e gramática são quase sempre corretas. O estilo da pequena janela e os botões de correção são de uso muito prático. O lado ruim é que ele parece apenas funcionar no YouTube ou páginas do Google.

Spell check feels inferior compared to Grammarly. For example, it doesn't think that phrase "below this corners" contains any errors.
