Firefox & CPU Usage/Heat

[Pax]

Id say flashlock would be a safe bet, I am using it with my firefox across all machines. Yeah its a few extra clicks if you're wanting to view content but the stress relief on the the system it is worth it.

You can also get flashblock for google chrome. But you have to enable extensions on the OSX version. Unless this has been added to the new upate without having to modify?

Correction:- I looked in Activity Monitor at the Flash process and windowed this movie used 38%, pretty constant. I couldn't see Activity Monitor when the video was full screen!

This is with Flash 10.0 r42, that's about 1/2 the CPU load of Flash 9. I still always use clicktoflash or flashblock

What are you using to visualize the CPU usage? If it's iStatPro, that's 80% on each core. If you're using Activity Monitor, that's 40% on each core (activity monitor displays up to 200% for dual-core machines)

im using menumeter and i have it set to average both cores.

but iv used activity monitor and it was 50-80% depends on the video. but sometimes videos only use about 30%

any explanations or is this normal?

It depends on the resolution of the video too, so that's why watching 720p or 1080i/p video on YouTube is quite the CPU hog.

You can try the latest Flash beta version, it seems to use less CPU power.

I uninstalled the normal Flash version with the provided (on the website I linked to) uninstaller, and then installed the beta version.

My CPU is used less now, not dramatically, but 15 to 30 percent less on a 2GHz C2D iMac.

but when i uninstall my flash and install the beta...videos wont play. it says install the latest version of flash

exactly which one did u download on that site? the beta 3? or the prerelease or what

I have no problem watching videos on YouTube or using Flash with the latest beta, be it in Safari 4.0.4 or Firefox 3.6 on Mac OS X 10.6.2.

I want to bump this thread because at least for me this issue is still pain in the ass...
When watching streams:
-Firefox: high cpu usage and heat production
-Safari: moderate cpu usage (in comparison to firefox totally acceptable)
Safari proves that its at least possible...
I'm using a MBP (mid 09, OS X Lion), 2.26 GHz, 8GB RAM, Firefox 9, Safari 5.1.2

Any ideas what to do about it?

Try Chrome and compare

CPU usage

See, here's the thing.... I watch BBC iplayer which uses shockwave. Now I have a macbook pro 2.5Ghz quad i7, SSD 6G and 8Gb Ram. I used to use a ****** Dell laptop that was around 8 years old... Now why would BBC iplayer run without fault on a Dell laptop and then not on a superpowered mac!! I understand that we can point the finger at flash but .... if shockwave demands a huge proportion of my CPU (which is pretty big) how the hell do others with lesser CPU's watch BBC iplayer??
