good job- FF needed this Rated 5 out of 5 stars

not an essential addon, but a no brainer great feature. Organizing bookmarks can be hard with hundreds of sites and folder trees. This helps me find a related bookmark so I can organize them easier and group them. apparently right clicking on the bookmark in search results shows the folder it's in. wasn't clear at first. Thank you. Now if only this could be incorporated in the default bookmark window such that selecting the bookmark when searched for also shows it's location. that would help, but this addon is the next best thing.
UPDATE:
it appears she has done just that and come up with Go Parent Folder add on which reveals the parent folder (by right click and select) within the default bookmarks window. thank you twice. and another add on Show Parent Folder as a column in the search results.

This review is for a previous version of the add-on (1.9.1-signed).
