When I opened tab check "send performance data," I don't have that choice of the tab. He wasn't there.

I followed the instructions to check the firefox slowness and high utilization of the processor. Tools > options > advanced > General > check "Send performance data," but it there was not a box to check. All the other boxes were there. Just not 'send performance data."

Quote: I followed the instructions to check the firefox slowness and high CPU usage.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

  • Do NOT click on the reset button on the startup window Mode safe or make changes.
