Every time I go to watch a YouTube video, it takes forever for the video to begin playing. When it does finally start, the quality is often very low, at 240p or 144p. I also have Chrome and Safari installed on my laptop and they do not have any problems playing videos. It is only Firefox. Also, I do not have this problem on my family's laptop, which runs Windows. It is only on my Macbook Pro.

Also, sometimes, various websites take a very long time to load, but this is not nearly as frequent as my problem with YouTube videos.

I have tried uninstalling and reinstalling Firefox, starting in Safe Mode, disabling various add-ons and plugins, clearing browsing data, and nothing has worked.

I have tried these suggestions and none of them solved my problem.

Is this with the Flash player or with the HTML5 media player that YouTube might be using by default in current Firefox releases.

I have tried using both the Flash player and the HTML5 player and both have the same issues. In fact, the Flash player will often not even load a video at all.

Just as a test, try downloading one of the files. Just to make sure the problem is the player.

Which files are you talking about, Fred?

The clip you are trying to watch. If it downloads, then that shows the problem is not the clip itself. On the other hand . . . .

I just downloaded a video and it played no problem.

Can anyone help me? If not, I'm just going to use Chrome.
