It's a great addon.

It's amazing. Easy to use.

Finally an extension able to execute what a web developer need to work.

Simple to use. Almost too simple. I clicked on the toolbar button expecting options and deleted all my history, etc. The simplicity is what makes it great. To prevent another accidental deletion, perhaps I should unpin it from toolbar.

useful.

Would be handy if it worked on a per url or active tab basis.
