Sometimes I do a keyword search for postings. The result page causes very high CPU or freezes the browser. Is there a solution? To reproduce: go to for instance https://www.facebook.com/cnn/posts/ and type a word in "search for posts on this Page". You can launch Task Manager to check CPU Usage.
I guess my first question would be what browser are you using? While Google Chrome is really popular, every time you click on a link in Chrome it opens up a new occurrence of Chrome which can slow down your surfing speed a great deal. So you could invariably have multiple instances of Chrome running all at the same time. The other thing may be to clear your cache on a regular basis perhaps. I occasionally will have some slowness with Facebook but it's usually only for a brief moment and typically doesn't last long (10 - 15 seconds on average). Also, do a Google search for Facebook pages freezing and you will probably find some additional help there as well. All the best!
