1164926 - Slow/hanging script stops navigation to another page in e10s.

Status: NEW

(Firefox :: General, defect, P3)

Description

[Jukka Jylänki]

STR:

1. Navigate to infiniteloop.html from bug https://bugzilla.mozilla.org/show_bug.cgi?id=1164286 .
2. Immediately once the "Connecting..." title appears, and the circle icon starts spinning to signal that a page is being loaded, and before the e10s "slow script" notification appears, manually type a new URL to the address bar, e.g. "http://www.google.com/" and press Enter.

Observed:

The browser does not navigate to the URL that was entered, but keeps executing the script (that is spinning in an infinite loop). Only after the slow script tab appears and user chooses Options->Stop Script, the navigation occurs.

Excepted:

The browser should immediately navigate to the page that was entered, instead of waiting for the slow script dialog to trigger.

This seems reasonable to me and the fix should be very similar to that of bug 1164286. This is probably more of a feature request at this point, though.

Hi,

I have managed to reproduce this issue on Windows 10, Windows 7, Ubuntu 14.04 and Mac OS X 10.7 on the latest Aurora release (46.0a2). To note that when the testcase from Bug 1164286 is used, all tabs lose their content until the script is stopped.

Moving to p3 because no activity for at least 1 year(s).
