I use Chrome
And do you know why I use chrome?
I was there through the browser wars, struggling to get Mosaic to work and then almost immediately going to IE and Netscape.
My experience from those times was one of frustration - incompatible rendering of HTML tags, Netscape offering a good alternative for a while but then bloating up beyond recognition and slowing down something aweful.. IE getting ahead, then getting almost seemingly abandoned by MS once they had "won" over netscape... I remember IE being very buggy at the time, and no new features coming in.. I used opera for a while, which was small, fast and felt like the future.. I think this was around about the same time that IE would always, when started, suggest that you change it back as the default browser (if you had something else set up) ... then competition from firefox and IE starting to pick up again.. more trying to get competitive edge via incompatible implementations, etc.
Now I have chrome, and it works.. it keeps being developed, there isn't really any websites that suddenly require a different browser (google keeps it up to date and running smoothly).. It works across all my devices... but the main reason why I am not changing away from chrome anytime soon is just this: it doesn't give me frustration. It works.
And as long as it doesn't frustrate me, stand in the way of what I want to do, mess with my system, bloat up and slow down my computer, etc, I will keep to chrome - life is too short to switch browsers every 6 months, especially if your current one is giving you no grief.
