Mozilla Lags After I Switch Windows and Loose Focus and Change Back
Hello everyone.
I've been having some issues with Mozilla lately. I don't know if my CPU is in bad condition or not but, when I change tabs through my Windows, say changing tabs from Mozilla to Spotify and changing it back to Mozilla, my CPU gets very full, causing my cursor to lag, and Mozilla to be unresponsive for a couple of seconds first and it gets kinda worse as I continue to use my PC, causing the lag to occur for over 10 seconds.
I have seen some similar complaints on the web but they date back to 2014ish times.
What do you think? Is it somewhat my CPU's problem or did Mozilla's handling get worse over a patch or something?
I enjoy Mozilla and don't want to quit using it. Any help would be much appreciated.

Assuming Firefox isn't locked up, could you use the built-in Task Manager (Shift+Esc) to see what process is hogging resources, whether it's Firefox, GPU, or a specific site's tab?
It seems that Mozilla itself, the top process, increases from around 5 percent to 35-40 when I change focus.
I wonder what it is doing. There is a profiler that can help track down performance problems in Firefox, but I haven't used it myself. Hopefully someone else can chime in on how to use it.
