Hi I had the same problem and was told to

Stop Trusteer Rapport if you have it running and the problem will go away.

You can stop and start Rapport by following:

Start menu -> All Programs -> Trusteer Rapport -> Stop Rapport

Re-started my computer and the problem has now gone.

Windows 7/64.

It worked for me too.  I didn't even need to restart. I just closed FF, stopped Rapport, restarted FF and all was well again.

I plan to contact Trustee Rapport about the issue.

I just confirmed the problem with Trusteer. (I was impressed with the speed of their on-line chat service.) They are aware of the problem and are presently working on a fix. They will notify me by e-mail when the fix is available. For anyone using Trusteer Rapport who is experiencing this problem, I recommend contacing them to get on their notification list. In the interim, they recommended that I unistall Rapport. I'm actually just using WinPatrol to (temporarily) disable it from starting.

A Tier 3 Support Engineer from Trusteer provided the fix (Rapport version 1205.8).  It solved the problem for me.  Here is the link I was given to download this version:

I did have some issues installing the new version.  If you have unistalled Rapport already, I wouldn't think you would have to repeat my experience.  Here's what I went through:

First I tried to install Rapport (1205.8) in my user account. The install program failed and said I must log in to an Admin account.  I logged out of my user account, logged in to my Admin account, and tried again.  This time it said I must uninstall on the other (user account) where Rapport was installed.  So I logged out of my Admin account and logged in to my user account, uninstalled Rapport (from Control Panel | Programs and Features), logged out of my user account, logged back into my Admin account, and then installed Rapport (1205.8).  Next I rebooted and logged in to my user account and tested Adobe Flash Player in Firefox (at http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html).  As I said, all was well then.

Hello Reno, worked for me too. Many thanks for your help. I think a "well done" to Trusteer too for the quick fix.

Regards.

what is Trusteer Rapport why should i download it is there no patch from adobe to fix the problem my firefox gets slow, and when i see the task manager i find several instances of flash player 11.4. r402 running after ending the task of this process the firefox again gains speed.

do i need to download Trusteer Rapport to fix the problem or should i roll back to flash player 10

Please help

No - I've no "Trusteer Rapport" product on my system.

I've had problems like many users after 11.3 and now after updating to 11.4 r402.

It is an conflict with "protected mode".

Setting "ProtectedMode=0" resolves the problem!

System:

Win Vista HP 32bit, all updates without iE/E 9

FF 15.0.1

This looks like the solution for me, but I can't figure out which archived player is for Firefox and Windows Vista.  Can you help?
