How to make firefox to spellcheck in multiple languages simultaneously?

Question

I want to it to assume that text may be in mixture of languages and words should be looked up in multiple dictionaries. (E.g. everything in en-GB, en-US, ru, be and be-classic should be consider as good, everything else should be underlined and corrections from all dictionaries should be offered). Is there an add-on for "multi-language spell-check"?

Alternatively, can I merge all dictionaries into one big combined dictionary?

Answer 1

Unfortunately, I don't believe there is an easy solution to this. I use two different languages on a daily basis and the best (not ideal) solution is a combination of multiple dictionaries and an add on such as:

Dictionary Switcher or Quick Locale Switcher

Both of which present their own problems.

Another, less than ideal solution, is:

ImTranslator

Whilst it is a translator, it also supports multilingual spell checking.

I also wish Firefox could do this. Not strictly an "answer," but you could try using Chrome, which does support multiple-language spell checking out of the box: http://www.google.com/support/chrome/bin/answer.py?hl=en&answer=95604.
