This is a bit off the Unix road, but I believe most people interested in the answer are linux or unix users so here goes.

For a long time it seems that the number one process chewing up CPU time and memory is my web browser ( mainly firefox, but others too ). It is true that I have a lot of pages open at once, so I generally don't mind, but recently it's gotten to the point where the browser just bogs down the system, and when I close some pages some sanity is restored.

What would be nice is if there were some tool or plugin that would tell me exactly what web pages/sites are using the most resources.

  • Out of curiosity, how many pages are we talking about here? 5 or 100? – Dylan Mar 20 '15 at 22:36
  • 1
    @Dylan, about between 100 and 500. – Mouse.The.Lucky.Dog Mar 21 '15 at 2:01
  • Wow! I was being sarcastic when I said 100. Why don't you use tab groups and favorites... That is a lot of resources wasted it seems. Perhaps I'm missing something – Dylan Mar 21 '15 at 2:07
