Perfect. I save a lot of web pages as MHT to keep the information. Line Marker helps me to point to the important parts in all the saved text.

For me it works without any problems even with Firefox 3.5. A great tool - thank you for it!!! Please make an update of the allowed Firefox version so that more people can use it.

This review is for a previous version of the add-on (2.0.2008040702).
