Doesn't work and is no longer supported

Let me save the next sucker some time. From the developer: *Not Compatible for Firefox on Android Yet*

Did not work at all.. went into history and it is still showing. I need it to delete the history when I close the tab. I even tried closing browser it still was there. does not work at all.

Hanged my browser three tabs in a row.
Then I found out it cleared out my whole brwosing history before I even add a single word to the list.
Would not recommend.

It just doesn't work.
