Note: This is my personal opinion and is not meant to reflect Mozilla’s views.
We’ve done a lot of work to help Firefox users have control over their add-ons (for example, bug 596343 and follow-ups 693743 and 693698) but some software companies are hard at work circumnavigating these protections. A while ago I filed bug 721258 concerned about the way the Ask Toolbar changes our 3rd party add-on confirmation screen. Today, in a follow-up comment I posted this screencast which shows an example of it in action:
Planet Mozilla viewers – you can watch this video on YouTube.
Some suggested that this isn’t that bad or that it could be worse. As someone charged with looking out for our users it’s pretty frustrating to run into that kind of opposition – just take a look at our support forum. Ask is known for this kind of stuff. And in fact, “how do I uninstall the Ask toolbar” is their top support question. It looks like we can’t do anything technical to prevent this at the moment. Maybe by drawing attention to it we can come up with another solution that protects people.
Clarification: At the end of the video, when I’m trying to fix the location bar search – the problem is that “domain guessing” is happening when it shouldn’t be (documented here).
