This is very useful. Thanks for sharing link

US patent business is really sad. Looks patents are given without doing enough investigation. I remember turmeric and neem get patented by some university of US, where India is using these herb from ancient time. Is it really given to protect someone's innovation?

I'm also still sticking with Chrome. Firefox's processor usage is really problematic for me. It keeps on utilizing ~15% of CPU even if only one new tab is open.

This isn't normal behavior, did you file a bug?

Thanks for pointing it out! It came out an extension(India Rail Info) causing this.

I have observed the same in my colleague's macbook as well. It could be some of the add-on causing this.

But surely, I need to dig down further to find the cause.

I've seen this too. However, they seem to have made improvements in Firefox 15. Previously, Firefox would take around 3% CPU with just the start page open; visiting a page with an animated GIF would push it to 12%; and, most troubingly, CPU usage would stay around that level even after the page was closed. Now, the same page still takes around 11%, but Firefox stays at 0% with just the start page open, and it goes back to 0% once you close other pages.

For me its firefox extension causing it. If anybody facing this kind or problem try disabling India Rail Info App extension.

question: is there a flash ad running?

It is 2012. Please install Adblock Plus, and add a subscription to one of the many Annoyance blocking filter lists.

Its firefox extension - India Rail Info App
