Q: Will it work on AJAX sites?
A: Yes. New added content into web pages will be examined.
Q: Why are some elements not highlighted?
A: Some types of elements including input, textarea and editable documents will not be highlighted because they will probably annoy you. For example, if you reply to an email, you would not want the recipient to see highlighted text.
Q: When I right-click on highlighted text, Edit and Remove options are not displayed.
A: That highlighted text might not be generated by the add-on. It could have been generated by the website itself or by other browser add-ons. Another reason is that the default context menu was replaced by another of the website or by other browser add-ons.
