We said it so many times here on Tech Support Guy, but looks like we will never say it enough. You should stay away from any programs claiming to fix errors in the registry. They will ALWAYS find errors to "fix", no matter if the computer has plenty of milleage or if it's brand new out of the box. The registry should be left alone, as there is no reason to "clean" it. It will, in most cases, make things worst, as important files still in use will be deleted in the process, rendering some programs, and sometimes the operating system, useless.
There are many reasons why a browser freezes from time to time. Misbehaving add-ons or too many of them is one reason. Having too many tabs opened at the same time is another one. Adware or other forms of malware can also be a cause.
