Is there a good alternative to Adobe Flash on Linux that's not a CPU hog?

Question

My CPU stays on 100 and sometimes drops to the high 90s when I'm using flash for Chrome and Firefox isn't much lower. I disabled the Pepper flash and enable hardware acceleration in Chrome://flags and it lowered it to the low 90s- high 80s, but that still seems a bit high and I've heard the only problem is most likely Adobe Flash itself.

Does anyone know of a good Linux alternative to Adobe Flash or are there more things you can do to reduce CPU? My processor isAMD Sempron 145 if that's of any use.

Solution

Quoted from here

It will ultimately require two: Gnash and Lightspark. The two projects cover different versions of the Flash specification; Gnash is the more mature project, and supports Flash content up to version 8. Version 9 of Flash debuted sporting a rewritten version of ActionScript based on an entirely different virtual machine model; Lightspark implements this newer framework.

Download Gnash from http://www.getgnash.org/packages/

Download Lightspark from https://launchpad.net/lightspark/+download

To install Lightspark in Ubuntu

sudo apt-get update

sudo apt-get install lightspark browser-plugin-lightspark

UPDATE:

Shumway is an experimental web-native runtime implementation of the SWF file format. It is developed as a free and open source project sponsored by Mozilla Research. The project has two main goals.

Also you can try Pepper Flash Player which is maintained by Google, and is newer than Adobe Flash Player.

Installation:

sudo add-apt-repository ppa:skunk/pepper-flash
sudo apt-get update
sudo apt-get install pepflashplugin-installer
echo '. /usr/lib/pepflashplugin-installer/pepflashplayer.sh' | sudo tee -a /etc/chromium-browser/default

GNU Gnash ; package gnash (GNU Shockwave Flash (SWF) player).

I don't understand how to download them. The files are on my computer, what do I do next? Are there terminal commands I can do instead?

[BigHippo]

And neither of those packages have been updated in 2 years. Will I still be able to keep using them?

I'm not having much success with anything outside of YouTube to work. Shame really that we have to depend on Adobe so much with flash.

[Maythux]

you tried lightspark?

[BigHippo]

Yes, it doesn't work too well with stuff other than YouTube.

[Maythux]
