United States English Spellchecker (8.0)
A. Ease Of Use: 4.5/5 – Very very easy. Just don’t by mistake add an incorrectly spelled word to the dictionary.
B. Security: 5/5 – No Impact
C. Usefulness: 4.5/5 – Just be aware the dictionary is very hit and miss. But I find this is by far one of the best add-on English dictionary available. Just don’t expect any Canadian word variations in it like “Colour“.
D. FireFox Slow Down: None
E. Computer Slow Down: None
F. Type Of User I Would Recommend To Use This Add-On: Any level of Firefox user will find this add-on useful
