If you can stop the pages from lagging by disabling the Flash plugin, then it's worth a few more Flash troubleshooting steps.

To test that:

orange Firefox button (or Tools menu) > Add-ons > Plugins category

set Shockwave Flash to "Never Activate"

Then try Facebook. If it's fast again...

This is some standard guidance that addresses the most common issues with Flash in Firefox. I'm sure you've seen some of it before, but just in case:

(1) If you have any video recorders/downloaders that interact with Flash media, make sure they are as up-to-date as possible, or disable them temporarily.

(2) Disable hardware graphics acceleration in Firefox and in Flash

(A) In Firefox, un-check the box here and restart: [YOU DID THIS]

orange Firefox button (or Tools menu) > Options > Advanced > General > "Use hardware acceleration when available"

(B) In Flash, see this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

(3) Disable protected mode (Windows Vista/7/8)

See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

Any improvement?

Does it have any effect when you disable smooth scrolling?

  • Tools > Options > Advanced > General: Browsing: "Use smooth scrolling"

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.
