Yup. Flashblock.

Turn it on for a page if you need/want it.

Adobe has never produced anything except communist bloatware. Adobe is the big-dig union boss of the PC app world.

However, Bill Gates and his Bangalore Boondoggle did give them some real competition with Office 2007.

An amazing breakthrough! Animated content uses more CPU/GPU power - and hence more battery capacity - than static content! I wonder if they thought about the implications of watching a YouTube video? I bet that drops the battery life at least as fast.

In fact, I’d be willing to bet that any active video usage would harm battery life. I know, shocking...;)

No, it doesn't. Works fine. Especially YouTube that h.264 optimized. Flash is a power hungry hog.

There is some truth to that... but not as much as Flash.

Per Anandtech, the Macbook Air 11 sitting will last 419 minutes, doing just MP3 playback and 3 web pages (static only) every minute.

With 3 browser windows open, and 1 to 4 flash ads, pages updated every 20 seconds (same rate as before), you get 289 minutes, a loss of 130 minutes.

With the same flash setup, but playing back an XviD movie and downloading files, you drop to 152 minutes, a loss of 137 minutes.

Flash doesn't seem to be much worse than other video decoding/activity, in independent testing on the same hardware. So it's really no surprise that battery life "dies" when you're doing video/animation displays.

I pictured somebody saying that Apple artificially inflates their battery life by not installing flash. Maybe I’m just jaded.

Adobe Acrobat and Flash are just more bloatware than a computer really needs.

Expecially on a Mac where the OS can inherently read and manipulate PDF files. I haven't had any need for the broken Adobe Reader.

Flash ads were tested, which would be simple decoding of vector graphics commands, displaying text and manipulating some bitmaps, something OS X does all the time itself due to Core Animation. With Flash that takes almost as much juice as decoding an MPEG-4 stream, one of the most processor-intensive activities the average computer user does these days.

Something is not right with Flash. With it, browsing the web can kill your battery as bad as playing a movie.

Another point: They used XVid, not optimum for OS X. OS X can accelerate H.264 video on the graphics card to save battery life.

If I’m on my laptop and browsing the web and the fans start spinning up, 99% chance of there being a Flash ad on the page. Blocking as much as possible extends the battery life quite a bit and keeps the fans from spinning up.

So yeah, it's not a surprise that a "richer" web would require more resources, but it doesn't speak well for Flash's efficiency to find a laptop loses a third of its longevity when running it.

Just open "Activity Monitor" where you can see how many resources Flash really requires. I removed Flash plugins from Safari, and use Chrome to open Rush video feed. Chrome uses about 50% of the CPU with their version of the Flash renderer.

Long live "Flash" and Word Star.

Hell, not just that. Apple artificially inflates their stability data too, by not installing unstable crapware.

And artificially inflates their security data too, by not installing Internet Explorer 5 any more.
