I won't argue that point, but think about it... what would be in it for Adobe? Unless the big players that Adobe has to cater to push them to provide Linux support, there's no real reason for them to.

Linux users would have to raise enough of a stink with those that provide Flash content (not Adobe themselves), who would then in turn have to push Adobe.

In this particular case, the OP should be raising Hell with Yahoo.

Point taken, but I choose to remain grouchy about it.

8 or 9 years ago I lost a new Linux User to lack of timely Flash updates. Ever since I've blocked all Flash content. I'm not interested in dealing with something that doesn't have anything but a tepid attempt at running on 'Nix. So for me it's HTML 5 (or some other recognized Web Standard) or nothing.
That's an admirable position; unfortunately, there's still too much Flash-only content to abandon it altogether. I went on YouTube's site and opted in for using the HTML5 player "when possible." Short of disabling Flash, how can I tell whether the HTML5 player is actually being used on a particular site?
Right click on the video. The drop down will say "About HTML5 Player" or "About Adobe Flash Player". I have not found many sites using HTML5 other than YouTube.

Thanks, richb.

I noticed that enabling HTML5 doesn't survive shutting down Firefox. I have to enable HTML5 each time FF starts. I guess that has something to do with cookies, which are deleted on exit.

Another thing:

I did a benchmark of sorts on the YouTube site (Grilled Grilled Cheese video). With Flash enabled, the CPU usage is 40-50% with CPU temperatures stabilizing around 113°F. After switching over to HTML5, the CPU usage is 90-100% with CPU temperatures stabilizing around 135°F. Using HTML5 results in a significant performance hit IMO. Is there some way to fix that?

Curious. My CPU load with HTML5 is about 10% and temps only increase about 3%. Google Chrome also retains the HTML5 setting.

Yes, G.C. produces much better results. It must be a problem with Firefox's implementation. After Googling around a bit, I see others complain about high CPU usage with Firefox.

EDIT:
It seems that Firefox doesn't support GPU accelerated windows for my particular video card. When I type in about:support and scroll down to Graphics, it shows only 0/1 Basic instead of 1/1 Direct3D. This has to do with Mozilla block listing certain GPU/driver/OS combinations that crash or result in instabilities. Luck of the draw, I suppose.

Maybe not surprising as Google own YouTube.

I used to spend a lot of time on a site that used/allowed Flash advertisements. That was so intrusive that I keep things setup so that I have to go out of my way to allow Flash to play.

I suppose that I'm in a minority in that I don't particularly care for UTube. Occasionally I need Chrome/Chromium for that sort of thing. But it's very occasionally for sure.
For me video and a PC don't 'fit'. I guess I'm a 'Reactionary' about it.

PS: (I'm also a grouch about Flash DBeckett.)
Yes, even I am dishonest. Not in many ways, but in some. Forty-one, I think it is.

This is probably apples and oranges but playing around with Grilled Grilled Cheese shows only about a 2% difference between Flash and HTML5, both around 9-10% on this hex-core machine. Quality is definitely better though using HTML5.

Mine shows the same thing for my Radeon card.

It's not that I don't want to use Chrome with Pepper Flash -- but Chrome/Pepper wouldn't install in Mepis 11 last time I tried (a couple months ago), due to a dependency that couldn't be fulfilled, and though it runs fine in antiX and anitX is great on my Core2Quad, Chrome for Linux won't run Java (apparently it does just fine with Java on Windows). I'll have to look at Pipelight; if I could run both current Flash and current Java from my preferred browser (SeaMonkey), without having to boot out of Mepis to antiX, I'd be a pretty happy guy on Internet game nights.

Edit: Ummm... I don't see Pipelight in the Mepis repos. Where might I find it in .deb form, or will I have to install it as a tarball?
