Mozilla firefox 3. Looked for addons and only canadian, greek, australian and US English available???

concise precisely colour

Hurray success! I found it. Couldn't find it searching in addons as it didn't come up under searches for spell checks. But the right click short cut on a page brings up the language option. Only en-US listed but under that was Add Dictionaries. And after selecting that it has listed English (British), so I installed it.
