Firefox does what I want about as quickly as anything out there, ( don't notice any difference from other browsers ). And it's the freest major browser out there. Do you seriously want Google knowing anything more about you than it already does?
I still trust that Firefox doesn't have hidden code against my interests. Can you say that about any other major browser?
I did recently switch to Pale Moon, since it's basically Firefox without the Lame. But Firefox isn't really all that lame to begin with. I switched back from Pale Moon, due to a Flash security update that wasn't yet applied to Pale Moon. I have been planning to switch back, but I might not - Firefox isn't all that Lame to begin with.
However Firefox did recently make Yahoo the default search engine in the search box, and then seems to have removed all other choices, and I have not been able to re-enable them.
I tried just using Yahoo, but it soon became too annoying, I wanted to support Firefox by giving them clicks, but I got tired of clicking on the home page button to get to Pale Moon's home page which I set Firefox to use( it's not bad, and it lists stuff I might not have used or heard of - keeps me current on the latest stuff out there ), and then clicking on the Google search link I put there, or searching for google in the yahoo search box. So I installed Quick Search Bar, which is an addon that seems to have given me back my choices of search engine.
I don't own a smartphone. I don't even own a tablet, or 'pod' device. My 9 year old kid does, and it runs Android. My impression is that the OS's available for such devices are Lame incarnate. Everything wants your credit card number so it can charge you for in app purchases, and they've made it purposefully annoying to get gift cards. You can't get Google Play cards online. You need to go to a store that carries them. THey want your CC number SO BAD. At least Amazon lets you buy gift cards online, and email them to the recipient ( though it's not obvious at first how to do that - they want your CC number too. )
If a non-profit like Mozilla came up with something for tablets/smartphones that catered to me, instead of app-makers I might be interested in owning a smartphone or tablet/pod. Until then I don't even want one.
And fsck Apple. Eww.
