Default ruleset causes groups.google.com to show blank pages in Firefox

[dgonyier]

I narrowed the issue down in the default ruleset. Commenting out the injected function line below allows groups.google.com pages to work again

[Inject]
function='DM_tag'
function='OA_show' 
#function='_gat._getTracker'
function='quantserve'
function='s.t'
function='setOmniturePageName'
function='urchinTracker'

Not sure when this issue started but I am seeing it in Firefox 41.0.1. It might have been an issue for quite a while.

Confirmed. This is probably broken as either part of the recent e10s compatibility update, or related Firefox changes; the objects that get injected aren't as accessible to content as they once were.

This beta version should help. Confirmation would be very nice.

Doesn't work for me unless I toggle KarmaBlocker off and back on. 0.6.2beta2
or if I delete the rule in the OP it works as well

I looked at the problem, saw the failure, simulated it to make it easier/faster to test and fix. Then pushed the above beta. Turns out I only fixed the first issue, and for the real site there's more.
