Last part of long texts are not spelling checked, why?

I use FF as spelling checker for long HTML files. It seems that after about 10 screen fulls the spelling checker stops working (which I notice from HTML tags not being flagged after 10 pages or so).

Chosen solution

The limit of flagged misspellings is 500 by default. To increase the maximum go to about:config. Then adapt:

extensions.spellcheck,inline,max-misspellings

Exit FF and start.
