Which browser are you currently using? Post why in your a comment.
I am using Chrome because of the bookmark/extension syncing. I've been having some issues with it and some extensions I use (memory leaks), but I have a hard time switching to other browsers like Firefox because I like the extensions on Chrome better than the addons on Firefox. I mostly use Google Hangouts (which does have a Firefox addon, but it doesn't work as well), and a few others for work that aren't available for Firefox.
