Teeny tiny multiplied by 7 Billion by 365 days per year by 24 hours per day by a fraction of a kW does add up.
7B people are not watching youtube on Firefox 24/7 365 days a year.

Isn't this more a failing of the operator: using a consumer grade OS for an industrial case?
I cringe whenever I see a BSOD or other usage of Windows on appliances in public. There are such better options available.
Meh, I see Ubuntu black screens in public appliances as well.

Funny how that sort of thing can work out. I was involved in an industrial optimization company years ago. Microsoft came out with power-save features in their new release. The staff at a metal-recycling company we were installing at, started complaining that the furnace would stop optimizing overnight. We investigated. The controller computer would go into power-save mode, which suspended our control app. So the fur…
> It would literally have been better if they'd never invented power save mode. Only if you considered the purpose of power-saving mode to reduce total energy usage, vs to reduce amount of power (and consequent wear & tear) an individual machine uses. However that MS would release a feature like that which automatically kicks in on upgrade without any sort of consideration of what the machine was used for - it could…
Life support systems don't run windows. And if you're running consumer windows on anything critical, you fucked up.

Well, also Firefox is making an excessive number of calls to that slow system call compared to other browsers (Chrome, Edge).
My understanding is that until recently (January), V8 (inside Chrome & Edge) made a similar number of calls. The main use is making it so that JIT-generated code is not writable while it is executing. It's an important security measure. V8 switched to a more recent mechanism (memory protection keys) that have been gradually getting support from the various OSes. But IIUC, they switched off the mprotect/VirtualProtect…

I have malwarebytes premium and defender CPU usage is nearly 100% at times bringin Firefox to a halt. Chrome works fine..I've been blaming Firefox so far.
In my experience (as a former Firefox dev), antivirus / antimalware software are really poorly behaved. They tend to: - require admin rights (which means that if they have vulnerabilities, it can take control of the entire machine, even if Firefox itself is sanboxed); - monkey-patch the Firefox executable in memory, which works (when it does) as long as the version of the software tracks closely the version of Firefo…

I had always assumed that one application could not touch the memory of another application. Does running as Admin allow breaking this boundary?

> a ~75% CPU usage reduction was noted when browsing YouTube in Firefox I wonder how many of the people who say "Firefox is significantly slower than chrome" are using windows... On my computer, Firefox IS slower than chrome but (with ad blockers enabled) by an insignificant amount. By still being "the last remaining mostly independent, maintained and reasonably popular browser" I'd prefer it to use over chrome even…
I'm happy this was found and its not clear if this is already patched, but hopefully it will somewhat improve performance on youtube or other sites like it going forward.
