This is the most helpful tool for as many people as I have to communicate with.

very useful, it points out my grammar mistakes and it helps me find the meaning of words with the double click popup feature. but this feature doesn't work with reader view (firefox's reading mode). Please fix this!

very helpful

I like Grammarly for Firefox but I can't find the extension for Twitter. Grammarly claims there is an extension for Twitter but there is no way of accessing it. Grrr!

when I copied rom gmail and pasted to my facebook, it seems that parts of the text were recopied or corrupted.
