I recently upgraded my very stable Firefox 3.6.16 to Firefox 4. I noticed that watching YouTube videos on FF4 is incredibly painful, as the video skips and stutters, then pretty much shuts itself off (like a pause that I can't resume). I noticed it in particular with this video
YouTube - Fleetwood Mac - Little Lies (Live) Good Quality
No amount of reloading/disabling addons/reinstalling FF4 did the trick, that video, among tons of others, still stutter. I looked it up on google and saw that some sites suggested going to about:config and changing the browser.sessionstore.interval value from 10000 to 120000, which had no effect at all. I cleared the memory of firefox (tools -> clear recent history -> cleared everything). Interestingly, I downgraded back to FF3.6.16, and had absolutely no issues with that video, or any other ones I tried. This is coming from a MBP 2010 with Nvidia 320m. Anyone else having this issue? Or any suggestions to solve this?

I have had those same exact issues before in the past on Firefox (prior to 4) (and only on my mac with a 320m).... I used the Adobe Flash uninstaller program, then reinstalled flash and it fixed it (just reinstall usually wouldn't).. that actually has happened many times around flash 9 to early 10.1 and it always fixed it, at least for a few weeks at a time. I don't use the 320m mac with Flash really anymore, so not sure if the problem still happens every few weeks.

I played the example video on my 320M equipped MBA, with a considerably slower processor (1.6 GHZ) using Firefox 4 on OS X 10.6.7. It played perfectly, full screen, at 480P resolution (the highest selectable).
Question:
Is the video loading into the buffer, and still skipping (the dull red bar ahead of the play point)? -

I have not had issues with Flash playback on my system, including 1080p Flash videos, under Firefox 4 but it does consume more resources than the previous version and Safari. For example, I have about 89-92% free CPU resources when playing back a 1080p Flash video in Safari (unless I have other programs open, then it drops to about 75%). That gets cut down to 75% just with Firefox 4 and then down to about 55-60% if I have other programs open.
I have tried completely removing Flash (with Adobe's program), installing either version 10.1 or 10.2, and I keep getting the same results with Firefox 4. Firefox seems to be consuming more resources in general when compared to Safari yet it runs great on my Windows 7 nettop with a dinky dual-core Atom processor and 2GB of RAM. I am not sure what is going on but I am guessing, based on my experience, that Firefox 4 for OS X isn't as solid as it should be. -
I tried the video both fully loaded (paused right away and let the red bar reach the end of the video before playing) and having it play while it was loading (my internet is fast enough that it loads quicker than the play rate). Both times I got stuttering.
Thanks for the tip, doh123. That seemed to work. I guess I will see how video goes for the next week or so to try it on different videos before I will say it fixed my problem.
Thanks again!
