This addon is one of the most useful I have installed. I love that it's quick and simple, and yet powerful.
Unfortunately, I think the latest change, where the password generation UI moved to a toolbar button (instead of the pop-up window) takes this add-on backward in terms of user-experience.
* The new button now unnecessarily takes up space on my toolbar. Moving it to the menu requires an additional click, plus causes the UI to be clipped so a horizontal scroll is required (which is bad user experience)
* For some reason the right-click functionality doesn't open the "Generate Password" UI. The only way I'm able to make it pop is by directly clicking the toolbar button, which takes away the locality of this function.
* The right-click menu now requires an additional level instead of quick selection

It just seems like these changes fix something that was not broken, while not providing any new functionality.
