Mozilla thought it would be a great idea to install AI features in Firefox and that brilliant decision may be causing your issue. Those AI features use an absurd amount of resources on some websites and when they’re enabled on my laptop, FF regularly shows ~50% CPU.
When all that BS is turned off CPU use drops to less than 2% most of the time. Search for “AI Controls” in settings and try shutting them all off.


















Interesting running those… Haven’t had to worry about benchmarks on my system, both Chrome and FF are plenty fast. I do wonder how the performance of Chrome with ads would compare to Firefox with the same ads blocked? Every once in a while I use some one else’s computer and can’t believe how many animated ads show up on pages I frequent.
Do you just put up with the ads or block them another way?
