User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.4) Gecko/20100413 Firefox/3.6.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.4) Gecko/20100413 Firefox/3.6.4

Firefox 3.6.4 Runs Slow when Adobe Flash has loaded games on facebook. The actual game is slow and also when clicking on menus in FireFox it takes longer for them to load.  Also when loading multiple tabs or FireFox windows they are all slower than normal.  When I change to a different browser everything is fine when Adobe Flash is loaded on Facebook.

Reproducible: Always

Steps to Reproduce:
1. Login to Facebook
2. Load any Flash game (Farmville, Treasure Island, etc.)
3.

what version of flash do you have installed? Does it happen in safe mode? http://support.mozilla.com/en-US/kb/Safe+mode

Comment 2

[Karl]

I have flash version 10.0.45.2 installed and in safe mode the problem is more intermittent, but there still is a lag.

How about a new profile? http://support.mozilla.com/en-US/kb/Managing+profiles

Comment 4

[Karl]

I created a new profile and FireFox is still running slow when a flash game is loaded.

i can confirm the slow behavior
with Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.3a5pre) Gecko/20100420 Minefield/3.7a5pre ID:20100420040941 + Flash 10.1.53.21 (RC2) if the Flash-Game containing Tab is in focused state.
if the Flash-Game containing tab is in background state, chrome UI elements are quite usable.

Confirming based on comment 5.  Juan, Marcia, you might want to put this on the radar for the 3.6.4 OOPP release.

Comment 7

[juan becerra [:juanb]]

Karl, do you see the same problem if you use Firefox 3.6.3?

Comment 8

[Karl]

The flash games themselves ran slow in 3.6.3, but the FireFox interface did not slow down.

Perhaps this is related, when flash videos are played in my case one video play fine and in another all interface buttons of flash are none or very little responsive, slowdown the response of all firefox.
You get many crash of the plugin?

I have the same problems on Facebook when I load/play any games on facebook.  I had FireFox verison 3.6.4 and just updated to 3.6.6 and it is still slow on my dads work computer (Windows 7), My dads laptop (Windows XP), and My moms laptop (Windows Vista).  All those computers and more we experience problems with facebook.  I used to think fire fox was extremely fast, now i believe it is slowing down. I hope they find out what is happening.  I have just updated adobe flash Player a few days ago.  It is some version of Flash Player 10, i am only 16 and don't know how to figure out exactly what version i have. It should have the latest version of flash because i updated it a few days ago. Hope this helps.

Some further Digging:
I did test Flash Versions 10.0.12.36 & 10.1.53.64 as the first and the latest of Flash 10 on WinXP and it doesn't make any Difference. The Facebook Games seem to not work with Flash 9.

The sluggish UI Behavior (esp. in the Menu Bar) is noticeable even back to Firefox 2 (Mozilla/5.0 (Windows; U; Windows NT 5.1; de-DE; rv:1.8.1.20) Gecko/20081217 Firefox/2.0.0.20 ID:2008121709). So this is not a recent Regression if the Cause is on Mozilla's End.

As a note: if you test this against a recent Trunk Build be beware of Bug 579597.

Autoscrolling http://www.theepochtimes.com/n3/229736-your-tv-can-spy-on-you-ny-sen-schumer-warns/ is terribly unsnappy while https://apps.facebook.com/pockie-ninja-ii/?fb_source=appcenter&fb_appcenter=1#_=_ is loaded in a different tab.

Aurora 24.0a2 (2013-08-04) on 64-bit Windows 7. 3.7/12 GB RAM, 10% CPU in use while game is closed. Strangely enough, undoing the close tab, i can't reproduce the 25-30% CPU usage by Flash Player 11.8.800.94 anymore: 4/12 GB RAM, 20% CPU in use.

Resolving old bugs which are likely not relevant any more, since NPAPI plugins are deprecated.
