Rated 5 out of 5 stars
As soon as I installed this extension I looked everywhere for the RegEdit tool in Firefox, but I could not find the tool anywhere.
Then I came back to this page and looked it over again.
I selected the key in the example displayed here and right clicked it!
There was the tool!
Remember that you must select a word, right click on it, then select the "Open In RegEdit" tool.
It will open in RegEdit immediately!
This is an awesome tool!
I highly recommend this extension!
