Problem solved, now it highlight all saved words. I uninstalled vocabulary highlighter and then deleted the "vocabhighlighter" folder in "AppData\Roaming\Mozilla\Firefox\Profiles". Crash problem after having more than 200 words added to the list.

Hi. Vocabulary Highlighter won't run with Firefox 15 or later. The crashing issue will be fixed in a new version of the add-on.

Great Add-on. It only highlights the last 27 words. Is there any limit? How to make it highlight all saved words.
