A long-abandoned repository... Several updates are needed. Until then, unfortunately I can't recommend the addon.

Having issues on iPad

I was disappointed that this doesn't appear in the list of browsers so I could make it my default. Having to click on an icon and then a large box just isn't convenient. When the addon actually lets me search from Firefox's address bar, I'll call it good. Until then, it doesn't work for me.

This add-on no longer works for me. If I enter a search into the address bar I either get the results from my previous search or I am taken to the Presearch start page with the notification "Form has timed-out, please re-submit" I disabled and re-enabled the add-on but it's still the same.
