[FireFox] Anyoe using RequestPolicy extension? I just installed RequestPolicy extension on Fx4.01 (developer says it works with Fx4+).
It looks really neat. It suggested that I immediately whitelist the very sites I want to block other sites from making cross site requests to! So, I did not put any sites automatically into the white list.
I clicked on a tab open to this site and had to allow a request to i.dslr.net. Fine. I also noticed that RequestPolicy was blocking Proxo. So, I allowed that globally. I denied this site's request to Google's leapis.com. Everything seemed ok. I read a thread here and clicked on a link in the thread to a newspaper site's article. I was disgusted by the LONG list of cross site requests made by that site and I let RequestPolicy block all of them. It was a long article and I was about halfway through reading it when I got a VERY RARE popup from Fx saying it had encountered a problem and had crashed and wanted to send a report to Mozilla. I allowed the report to be sent, along with my comment that I suspected this new extension I had just installed as being part of the problem, and I even gave my email address which I don't usually do on reports like this.
Firefox restarted and after all my tabs (about 40) loaded, I noticed Fx was using 50-100% CPU constantly. I read a thread here, watched the CPU usage continue at 50-100% for Fx and decided I should disable RequestPolicy. It told me it would not be disabled until I restarted Fx which I did and CPU usage was back to normal after my tabs loaded.
I'm wondering if I had started Fx with only a tab to my homepage (here), and no other tabs, and then each time I opened a new tab to a site, dealt with RequestPolicy, if that would avoid the high CPU usage and eventual crash of Fx? Maybe I just don't understand the point of this extension. What does it do that a hosts file will all those sites in it doesn't do? (It did show me sites I don't have in my Hosts file so it is useful for cluing me into what sites I need to add to the Hosts file).
