Brilliant Rated 5 out of 5 stars
This is the very most useful Add-on that I have.
I now have toolbars full of customised buttons that are specific to the browsing that I'm doing.
Some I've downloaded from the Custom Buttons Forum Database, some I've downloaded and "tweaked" to make them absolutely what I want, and some... well I just needed to use the MakeAButton button - job done.
You can even "Request a button" to be authored for you on the Forum!
The guys there are very hepful and they really know their stuff!
