While drbrain is right with the recommendations for browsers, I think you mean that you want to block the pop-ups for your users, not just for yourself.
While I understand that you don't like the popups on your site, the only way you are going to get a popup-free experience for your visitors is if you switch to paid hosting. There are a load of hosting companies out there which offer real hosting for less than $5 a month.
The only problem I notice is that they generate about 20 html errors!
But yeah, go to getfirefox.com and get an updated browser for free.
