@OP, maybe you can tell us anything about your device's specs? Such as your CPU, RAM, and VCard. Because based on my understanding, running an auto-bet on a background esp in a browser would eat huge capacity in your processing units.
here's my device's specs:
- Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz
- 16 GiB RAM
- GM108M [GeForce 920MX]
Your CPU specification is more than enough to play offline gaming or online gaming. With 16 Gb RAM, I am sure you will not have a problem or lag in accessing one or more tabs in your browser. So there is something wrong with your OS because the process consumes high temperatures. Did you already check the add on for every browser you installed? If you forgot to install one or more add-on and that is from an unknown resource, that can make the process needs more.
The last thing you can do is reinstall your OS, install a clean installer, and don't use any add on for your browser to see if that will impact your CPU process or not because you can monitor in the process. Try just to install chrome and don't install the other browser, and see what will happen.
