Firefox lagging and high CPU spikes when managing e-commerce backend tools

Firefox App responsiveness

Hi Mozilla Support Team,

I am experiencing severe browser lag and high CPU usage on Firefox specifically when managing complex backend forms and inventory management scripts on our e-commerce operations portal.

The page script execution freezes when opening multiple tabs alongside developer console tools. I have already cleared cache and disabled third-party extensions, but memory leaks still happen during heavy DOM rendering.

Is there a specific setting in about:config or hardware acceleration flag recommended for heavy web app environments?

Thanks!

So is it browser lag, CPU usage, or memory leak? And is it complex forms, or when opening multiple tabs along with developer console? Could you please attach a few profile captures profiler.firefox.com/docs where you see anything exhibiting this represented in the data?
