Works very well an is not intrusive in the text areas. It allows me to add to the dictionary and is fast to analyze. So happy, I actally pay for premium now.

It works and does what it promises, but could have a bit better UX, and be a bit more polished as it caused a few bugs in a few sites in the past year that I have been using it, but tbh a lot of the blame goes on the horrible browser-plugin API's...
But still, recommended!

It is better than nothing but is often not great at spelling mistakes. I will misspell the word literally as literly and it will not give the word I want as a suggestion but when I search that word the search engine corrects me fine (there have been other words too but this was the most recent). Plus, the addon does not work in some places (like here for example).

Presque parfait, si seulement il y a avait la variante Français Canada, je mettrais 5 étoiles :)

Me like it!

Поки що безтолкове доповнення, бо не підтримує чеську мову...

This is amazing! Very unobtrusive and so easy to use, and does a wonderful job. I love it - thank you, thank you. Great job! It would be really great if it worked with Wordpad, but I guess you have to be in Firefox?

Was working well for the longest time, but in the past month it's started messing up the corrections it does by deleting spaces and punctuation around the words being corrected.
