It was a pleasure having and using a singular source when correcting papers. I regard Mr. Schmiedge's effort as one more step on the road towards a good single source.

THANK YOU!! was sick of it putting a red line under colour (which is the correct spelling)

Canadian English is something of an orphan as no official Canadian English dictionary has been updated for at least 20 years. But it is nice to have an option that is neither UK English (no, we don't have tyres) nor US English (I utter colourful language when it's not a metre, darn it!). Thank you et merci, Paul Schmiedge.

I've been using this Canadian add-on since it was first uploaded to Firefox.
It's nice not to have the USA 'humour', 'colour', etc... underlined in red all the time, and having to right-key to ADD them to the USA dictionary.
