Firefox 49.0 for Linux openSuse 13.2 crashed after installing testpilot.

Dear Madame, Sir,

After installation and activating one feature of test-pilot, I think setting the menu bar to the left, my browser got stuck. It took ages to load a page and after some time it went black. It did not respond to anything. It also did not show the "Test-pilot" button in the top of the browser. That space aircraft icon. Other applications kept working as expected, only Firefox appeared to be looping.

I was not able to uninstall testpilot using the browser. I adapted the pref.js file, commenting out the newly installed features.

user_pref("extensions.@testpilot-addon.sdk.domain", "testpilot-addon"); user_pref("extensions.@testpilot-addon.sdk.load.reason", "startup"); user_pref("extensions.@testpilot-addon.sdk.rootURI", "jar:file:///home/ben/.mozilla/firefox/ng3p413a.default/extensions/@testpilot-addon.xpi!/"); user_pref("extensions.@testpilot-addon.sdk.version", "0.8.5-tag-2016-09-27");

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?

While still in Safe Mode,
