Only Firefox running in background
If you run with native Wayland (MOZ_ENABLE_WAYLAND=1), it will avoid rendering occluded windows.
Nothing has changed formally In fact, the processor fan stopped turning on, which means that part of the load was turned off. This is a good step in the right direction. Anything else I can do? That do you think about "safe mode"?
You can try Firefox from the official Mozilla server if you currently use a version from the repositories of your Linux distribution to see if it behaves differently.
You can create a new profile as a quick test to see if your current profile is causing the problem.
See "Creating a profile":
If the new profile works, you can transfer files from a previously used profile to the new profile, but be careful not to copy corrupted files to avoid carrying over problems.
Open Firefox Task Manager (Shift+Esc) to see the processes using CPU. You can also show threads by changing toolkit.aboutProcesses.showThreads to true in about:config. Record a performance profile to get even more details and a sharable link.
Using Wayland really help to decrease processor load. But there are number of processes working in background. I do not need it. Absolutely. How to disable any activity on inactive tabs and unfocused windows?

Does anyone know a working browser that does not load the processor with a bunch of background tasks and supports some kind of adblock? Opera?

Close processes in about:processes (Shift+Esc) to free up memory.
Reduce the number of processes per site by changing dom.ipc.processCount.webIsolated to 1 in about:config.
Unload tabs automatically by changing browser.tabs.unloadOnLowMemory to true in about:config and increase browser.low_commit_space_threshold_percent to make it more aggressive.
Install an extension like Offline when Minimized or Auto Tab Discard.
Have a look at this extension.
