It's a good practice to allow only original domain scripts for permanent (a choice " allow") to have the web site you are visiting to display correctly all the useful information, but to keep side or extra domains only in " forbid" or " temporary allow" mode so the next FFox load will keep all these unwelcome scripts banned again. So keep NoScript installed on all your FFox'es and keep track on what domain you are actually allowing scripts from to be executed very carefully. The simple (but not unique) solution would be to install NoScript plugin - causing immediate effect - Web Content process CPU consumtion will decrease almost to 0%. Those java-scripts are usually not origin of the web site you are working with but an ad based 3rd parties from somewhere else trying to collect some info from your FFox session or just to display switching ads on a side. The cause of the problem appears to be very simple: you may have too many tabs opened each having bulky and useless endless loops running java-scripts. This is a common problem causing nothing but the battery wasted energy decreasing unplugged operation time significantly.
