it goes both ways, i've seen a shitty opinion eventually become the better option, the truth is often not well tolerated when it is first heard. sometimes the mob is wrong but their voices are louder because they are many. but yeah an opinion becoming the better option is generally not the case.

but yeah i use ff and chrome depending on the site, i don't know the negatives about using ff, doesn't mean their aren't i just haven't heard too many bad things about them
