Hi,

There seems to be many Firefox processes running which consumes large amount of CPU and memory (attached) - I have only opened a single instance of Firefox however there seems to be problems with this. I end Firefox processes and start anew, however it appears the same. I restart the computer and open firefox it appears the same. I'm not sure whats going on. This is impacting my PC performance negatively.

You can open the Firefox Process Manager (Shift+Esc) to see more details.

Does it still happen in Troubleshoot Mode?
