How often does it make sense to update the software?

[shamer15]

I have noticed that every time a software update is released the programmers are trying to increase more and more API resources with very high power use, thereby increasing CPU speed and degrading performance. Based on the above, it's pointless to update the browser software to a new version. When I use the Firefox v100.0.2 the laptop is ready to fly, because of  the high speed and maximum frequency. Mozilla currently adding a new version of browser 101.0, so I don't know what to do.

True, updates are more and more frequent, but I also started thinking if the problems with performance are some sort of sabotaging from MS or Google... a tablet I use is having serious trouble to process images/videos, so I started to switch to Chrome in it...
