579745 - Prevent default installation of globally installed add-ons

Status: VERIFIED FIXED

(Testing :: Mozbase, defect)

Description

[Henrik Skupin [:whimboo][⌚️UTC+2]]

In the past we had a lot of problems with globally installed extensions. The most problematic one is definitely Ubufox on Linux. Recently we got other failures because it's not compatible anymore against trunk builds and prevents our software update tests from running correctly.

I think the best solution for our tests is to prevent the installation of global add-ons.

This feature is new in trunk builds of Firefox and can be invoked by simply adding the pref "extensions.enabledScopes=0" to a profile.

Would be great to have in the next beta release of Mozmill 1.4.2. Patch upcoming.

Patch with reordered preferences

Looks fine, though you might want to comment in the python why these preferences were added.  In the future, we might think about a few things for default preferences:

Having them in the python is at best questionable for any but the most needed preferences.  We pretend to "start with a blank profile", but as per these preferences, its not really true.  An .ini file is more editable, e.g. ~/.mozmill/prefs.ini .

Thanks Jeff, I will do it and attach another version of the patch.

Mark, do you also wanna have this default pref set in Mozrunner or is all that stuff not important for you?

No. It should be user.js. We can simply drop that file into the profile and all contained preferences will be set.

I will also add comments as proposed.
