One word - javascript. 25% of CPU means it is using 100% of one core if you have quadcore. Javascript executes mostly in one single thread. That's why all this slack, discord, etc javascript one-page "app" thing is complete nightmare. Browser based or standalone electron-based.
But if you have not yet installed - get an adblocker. Internet becomes 100% faster due to fact that most ads nowadays ran insane number of javascript.
It's just crazy to me how Javascript ended up becoming the foundation of the web, and by extension, a lot of other platforms these days (i.e. mobile through React Native, etc.). Particularly confounding is how it is the basis for a lot of cloud server technology due to Node. Ugh.. I've had to do some Node development for work and it's absolutely awful.
Which reminds me..
