Fóram Tacaíochta Firefox

This is being categorized as privacy and security issues since every other search I've done for such issues point to plugins or datamining/cryptomining viruses. I've done every possible scan for my system for viruses and nothing popped up, I've browsed Explorer manually for all the files and any possible anomalies, and nothing strange has come up.

I've attached an image of the specific process that is doing this. I would like actual help, not just "check your plugins" or "run an AV scan" or something of that sort. If it's an obvious troubleshooting step, I've already tried it to no avail. Not trying to be rude, I just don't like "support experts" that give super obvious advice when it's clear the asker already has knowledge of it.

Some further clarifications:

• Once ended through task manager, the process does not run again until I reboot my computer.
• Forcing it to shut down through the task manager does not close my firefox if it's open, nor does it affect it in any functional way from my observations. This process is seemingly entirely useless, which only further raises suspicion.

This one firefox process uses a lot of CPU and my cpu temps get up to 70 C which is the normal temp I get when running a stress test. Ending the process fixes the issue and firefox continues working but its really annoying to have to close it everytime firefox opens and sometimes I forget it only to find out that my cpu has been at 70 C for a few hours. How can I stop it once and for all?

I have to go into task manager to stop background processors from freezing my computer. Closing background processors in disk and memory. Sometimes there are as many as 10 background processors running but it seems to be a only a few and can't tell which one's until I figure it out. Sometimes I can by the amount of usage. I have to do this several times as I use my computer.
