Neo Diggler Serious Gotcha Rated 3 out of 5 stars
It is a good extension, with a major defect. It has a large button, and a small piece at the right-hand end of the button gives access to the url tools. But, if you accidentally hit anywhere on the rest of the button, the url disappears, and is not available in the url tools section, or anywhere else. It means that you have to reload the page, which in the case of a large page, can be somewhat time-consuming. I never need the "wipe the address-bar clean" facility, so this is a major pain in the backside for me.This review is for a previous version of the add-on (1.0.5).
Next version will have 'restore'
There's a sub-menu option to restore the URL to match the page. I'll try to upload it this weekend.
