Extension does not come up in website. I would use the extension if it was available to use.

I find there are often dozens of words and Canadian spellings this dictionary doesn't pick up, daily. Stuff that should be straight forward. From haemoglobin to borealis. How could these not be in there, but lots of stuff like this. Any time I comment there are legitimate words I constantly have to add, after vetting them with dictionaries. It's like not having a dictionary add on.
