Same problems, Works fine in Chrome and IE. I am on PC vista 64Bit

For what it's worth, if you're having the horrible frame rate/lag with flash on 3.6.4-3.6.6, just switch to either 3.5.10 or 4.0 beta.

Both work great with flash content.

I am having the same problem as everyone else seems to be. Ever since the last update of 3.6.6 my computer has been sluggish on sites, times out, and firefox won't even respond at all. I REALLY hope they release 3.6.7 or 3.7 soon.

Well, the x64 Win7 is not so flawless anyway... i experienced some other issues not only with FF & Flash.

As Kendal recommends, use in the meanwhile a previous version or a beta, i'm using now 4.0b1 and all my settings, addons and flash are working pretty good, also you can keep the 3.6.x version without any conflicts :)

It sounds like your internet connection. Mine loaded in less than 2 seconds (2mb/s Connection)

Try clearing your cache, history, temporary internet files etc.

If your flash player hasn't been updated, update it to the latest version.

I have the same performance problems with FF 3.6.8 and Flash 10.1.82.76 on a Win XP system.

The performance for some flash sites in MS IE8 is unfortunately better by factors - especially after images etc. are cached. On FF (for version > 3.6.3) it seems that cashing for flash contents - e.g. jpg-images that are loaded by the flash swf - does not work at all.

The bad flash performance is by the way independent of any flash settings (e.g. hardware acceleration).

Interestingly, none of the problems I have with FF under Win XP (32 Bit) occurs for FF 3.6.8 and the present flash plugin 10.1.82.76 under Linux (Opensuse 11.3 x86_64) . This should give the FF developers something to think about ....

Hi all!

I'm a webdesigner. I'm contructing websites with joomla. I'm rarely using flash animations because it occurs many problems on the site. ( XHMTL validation problems ). I was designing a flash headered site and I faced this problem too. ( in IE no problem everything gone smooth and in Firefox it was slow and page loaded also slowly). The problem is that firefox flash pulign cannot handle transparent background in the movie. It means that if somebody has "slow mashine" felling (in Firefox and not in IE) it is surely used a flash with transparent background. This is a bug of Firefox, im sure, beacuse my site was tested in IE and Chrome and no problem arised.

How do I uninstall Firefox 3.6.8 and reinstall my older version and where do I find my older version? Anybody can help? Thanks

It seems it doesn't matter as since update for my plug ins firefox as a whole as slowed way way down and running resources like crazy. Need to fix this. I have been checking around for answers and dont seem to find an easy solution or update to fix this so ff is fast again. It also doesnt seem to be just when on a page with flash on it. It slows all pages down. Once have like 3 pages / tabs open. Fast computer to so this should be fast as heck like it normally is. Thats one main reason for firefox. Cause it runs fast but now slow as can be as of 3 days ago. I updated flash, all plugins and extensions but still slow.

Anybody have any fixes for this and my like posted issue please share. I will be creating a thread myself on this as well so can post there to if dont mind.

Is there yet a published solution? This sounds like my problem, tho' once in a while I get "the connection has timed out".

I d/l'd latest adobe flash player, no help.

Thanks, Mike.

I have this problem too. Does an update will come soon?

Mozilla Firefox commits suicide finally. I had no problems with Firefox till version 3.6 but updating to Version 4.0 was my nemesis. It is idiotic, heavy and a hell lot of entries have come into config file.

It is now finally giving some tough competition to IE, by becoming as idiotic as IE.
