I have the problem that Firefox spends more than 10% of CPU on displaying a static webpage like google search results. I am running Firefox on a late 2012 MacBook Pro and the constant use of so much CPU drains the battery and produces a lot of heat after a while.
Steps to reproduce:
1. Start Firefox in safe mode, disable all extensions
2. Enter "why does ff spend so much cpu on google search results" into the address bar
3. Observe how the CPU usage of Firefox increases to a steady 10%
It seems that a lot of other users experience the same problem too, e.g.,
However, the routine answer to their questions has always been to restart Firefox in safe mode, disable all plugins, etc, etc. I have tried all that, nothing helps.
For me, the problem only occurs on the google search results page. I do not know what is special about this particular webpage and why displaying it needs so much CPU. It could be that Firefox uses a lot of CPU on other static webpages as well. However, a simple cure to my problems (for the moment) consists in switching to some other website when Firefox is idle. CPU usage will drop below <1% almost immediately after that.
