can be very slow Rated 3 out of 5 stars
i like this extension, but it can be incredibly slow when finding all instances of a stringi was recently forced to terminate firefox after using it because it would no longer respond - in this instance it found over 975 matches, but never listed them after about 5 minutes
Notepad++ listed all matches (and surrounding words) in less than a second
Currently, Find All is optimized for searching HTML documents, not plain text. I'll try to address this in a future release.
