1147812 - Cancel add-on installations when the associated tab navigates to a new site

Status: NEW

(Firefox :: General, defect, P4)

Description

[Dão Gottwald [:dao]]

Each notification representing an add-on installation step stays for at least 30 seconds and then disappears when navigating after that point. According to attachment 8578019 [details], we should instead cancel the installation when navigating to a new site, and there should be a warning before actually leaving the current site. I'm not sure how feasible this is. In the mockup this looks like what web content gets when using an onbeforeunload handler, but it's not clear to me that we can directly use that technique for our purpose.

The new mockups in bug 1120996 suggest that we should show a tab-model prompt asking if the user wants to leave the site or not before cancelling the install. I think that can be follow-up fodder though, sounds hard.

I think this should not be tagged [fxsearch] anymore
