Video streaming stalls after first several seconds for all sites.
This is for a friend's Win7, 64-bit computer. Since upgrading to FF 7.0.1, any time she streams a video (YouTube, Netflix, Vimeo) it will play the first ten seconds or so then stop streaming. It says buffering, but never buffers.
This happens in FF, but not IE.
When it happens, going immediately to SpeedTest.net shows speed peaking to correct bandwidth from ISP then immediately stalls, never completing the speed test.
Cache, cookies, etc, have been cleared. Flash/Silverlight have been cleanly reinstalled. No change.

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
Try to decrease the value of the pref network.http.max-connections from 256 to 30 as used in Firefox 3 versions.
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Thank you, cor-el, but these do not resolve the issue.
