If you need a tool that will change the url displayed in a within a particular frame this does the job.

Super add-on! Works as advertised and more (Off-topic: And thank you strelnic for changing your review and rating to something much more useful. It's frustrating to see so many 1-star reviews that have little to do with the intended function of the add-on, especially for good add-ons with only a few other ratings.)

Useful to view, but specially to save pages with the changes described for frames/iframes respectively.
As long as all Frame Ext functions except Change Frame URL work only with iframes and not with frames (like these http://download.oracle.com/javase/6/docs/api/), iframe only functions should not show under This Frame submenu for frames, only for iframes. That's what confused me before I edit this review sputnik1, but if that helped to waste your time it worth it =P
About Remove Frame function, Nuke Anything Enhanced addon inserts a Remove This Frame function into This Frame context submenu for iframes only, and not for frames, just like this addon should do for a function like that, for your information.
I also found that changing frame URL to an URL of some rich content pages, specialy with once in a session preloading ads redirections or so, the iframe got removed.

2 RedHorizon: Those functions are FF functions, not of this extension.

Excellent! I've used this for months on my old PC and find it really useful - especially the 'Show Only This Frame' and 'Open Frame in New Window' functions.

Works great but I wish there were shortcuts or ways to enlarge it every time there is a frame

I've been struggling with some some Facebook frames for the past week to customize who sees my game updates. Half of the frame was being cut off and I couldn't get to some buttons. No one could help me at the FB help center. This addon just fixed my problem! The Size to Fit allowed the frame to expand to its intended size. Thanks!

a poorly behaving iframe on a site I use was driving me crazy for a couple of weeks and this addon not only solved that problem it solved a problem with a different web site that developed between the time I started looking for a solution to the first problem and when I found this addon! Awesome, 'resize to fit contents' option is wonderful!

Easy and feature-rich! Rated 5 out of 5 stars

Very nice. I sometimes wanted to easily see the frame's url. This really makes it easy.

It does what it says; it can even load a framed page within a frame and then perform the same functions on the frame within a frame. Awesome!
