Recent updates to Firefox mobile disable the user's ability to immediately disable preset search engines (Google, Yahoo, Bing, etc). Current "solutions" that allegedly address this issue involve users having to make changes to json. A user shouldn't have to go beyond the interface(s) readily available through "Customization" option. I will not be using the current version of your mobile browser because of these anti-features, Mozilla. I would also encourage other users to do the same. If Mozilla is as committed to Open Source, empowering communities and its users (as its own Manifesto suggests), then Mozilla and Firefox's Devs must necessarily re-examine the flawed thinking that have led to Firefox's recent "nerfing" of user control. I encourage the Mozilla Foundation, Firefox, and Community Devs to more closely examine the implications of disabling a user's rights to choose for themselves; to disable those features and customizations they choose not to use. Over the past year, more and more people have stopped trusting the likes of Google, Yahoo, Microsoft, etc. Trust is a very fragile thing indeed. I've trusted Firefox since its early days, but recent changes (like this one) have caused me to question just how much Mozilla wants to empower its users and how much it respects its users' right to control, self-determination, and privacy. The question now becomes, "Can I trust you?"
