Maxthon 2.5.13.166 update

Just upgraded my browser again. I use a combo of Internet Explorer 8 as a base and Maxthon as an add-on skin thing. It seems firefox is trying to push their browser with the new skins (a.k.a. personas) which is quite easy and fun to use. But maxthon has really good functionality like a drop down list that you can create to store passwords for different sites/forum logins.

Vanille from Final Fantasy XIII is shocked that I only update my browsers once every couple months, how often do you upgrade yours?
