Hi, I am having an issue: Flash on Firefox is really sluggish (I only use it on Youtube) and on Chromium it is not. I tried the same versions under both (11.2.202.346 and 11.2.202.350) - I disabled pepperflash on Chromium, so they both were running the same version. However, on Firefox the performance is poor while on Chromium is fine (with or without fullscreen). What Chromium does differently?
Firefox is releasing updated betas almost daily because of issues with Flash. At first this had only a small effect on me as I've been using the HTML5 option on YouTube for a long time. HTML5 is noticeably better. Recently I got a Firefox addon that increases the preference for HTML5 but have had to disable it until Firefox gets this cacheing and flash problem sorted. In the meantime I have Flash configured to "ask" permission to run.
It could be your video driver. I know the OEM Nvidia and AMD drivers have some acceleration of Flash, but it's not that useful really. HTML5 is much better.
Flash Player 11.2 is an ancient codebase from 2012, which will only get security updates until 2017. It supports hardware overlay video only when using VDPAU, but this is broken too (color channels swapped). Otherwise it will convert YUV to RGB using the CPU and then paint it on the screen using X11 drawing calls, which is too slow for being usable.
Long story short: The Linux Flash Player is abandonware and broken beyond repair.
You could try running the Windows version of Flash Player 13 using pipelight.
I have seen good results with Firefox if I disable smooth scrolling. This function eats a little CPU.
Chromium also ships without smooth scrolling.
Check for updates and install the latest Firefox. Now I'm running version 28.0 and I have no problems with flash. If I'm playing some flash games it is true that chromium will give you some extra fps, at the cost of more memory being used. Delete cache once in a while and Firefox will breath a little easier.
Adobe Flash is built on ActionScript and Javascript if I'm not mistaking, so it is normal to see some little differences between Firefox and Chromium. They have different script engines.
And lastly disable any Add-ons that you don't use ...
PS: Happy browsing! And HTML 5 is much much faster

Reason: just that html5 is better
