I contribute a lot on Wikipedia, so, it's quite annoying not to be able to check the spelling of the whole text, even if it is long. Reproducible: Always Steps to Reproduce: 1. Go to any page with fields (example: edit a Wikipedia article) 2. Find one with a lot of text in it (>40KB; example: long Wikipedia article) 3. Look at the middle/end of the text in the field Actual Results: No misspell are found, even if there are some Expected Results: Correct spellchecking It seems to happen with all languages (I tested English and French). I happens in Firefox3 (32 and 64 bits versions) and also Firefox2.
Happens also in this comment field. Confirmed for Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:22.214.171.124) Gecko/2008092417 Firefox/3.0.3 as well.
The spell checker only flags the first 500 misspellings for performance reason. Maybe you are hitting this limit. You can try adjusting this number in extensions.spellcheck.inline.max-misspellings.
Hey ! It seems to work very well, thank you very much !
