Firefox Portable

After running the latest Beta with no additional extensions or add-ons installed, I found that a single registry entry is left after firefox is closed (HKEY_LOCAL_MACHINE\SOFTWARE\mozilla.org\Mozilla\CurrentVersion). This entry is also left with 2.0.0.12 so I'm thinking it has something to do with my computer. The only way I can get rid if it is to delete the value manually. Again I hope that it is just the computer I am using, is there something I'm not doing? Any help would be appreciated.

How can I download flash player so that it can be used by my Firefox portable? I'm unable to view movies in firefox that need flash player, but it won't read the flash player from my local computer with flash, even though on internet explorer, I can view it just fine.
Any suggestions?

Whenever I try the play a vidoe, such as on YouTube or a Yahoo news video, there is NO SOUND. The video plays fine. The sounds are all enabled. Just NO SOUND. I have Flash installed, but I'm not certain if it is working. It's only on my portable drive, not on the main computer.

While browsing with Firefox Portable, I would like to open AIM uri's (aim:goim?screenname=JohnDoe)using Pidgin Portable. Is it possible and how? Or is it something that would require registry edits on the machine?

Also, if this has been addressed elsewhere, please let me know what search terms you used to find the answer, as I've been racking my brain to figure it out.

So is there going to be a Firefox 3 beta upgrade?
The Beta 3 version is working great, I'm just addicted to upgrading

Can i use "QuickRestart" Add-ons?

No problems?

When using Firefox 3 Beta 3, a Extensions folder is left behind in the Application Data folder.

Does anybody know, how to (manual) install the VLC Plugin for FFP 3beta3? I use the VLC regular version (not portable) and already tried the mozilla-plugin-option during the installation.
Same problem with WMP 11 Plugin (tried this one), but DivX and the older WMP are working fine. Dont know why

Thanks!

Hey Folks
I got a tip to stop flash ads automatically playing by adding to the userChrome.css
but their is several directories named chrome in the portable install, I think I copied it into all of them, but it still seems to of had no effect..
which one is actually used?

the addition to the userChrome.css is:

/* Block Flash, using a placeholder you can click to unblock a desired Flash animation. */
/* Doesn't work for embed tags, which are less common than object tags - bug 190970 */
object[classid$=":D27CDB6E-AE6D-11cf-96B8-444553540000"],


On the wiki site quoted
"However, Portable Firefox leaves behind downloaded temporary files with their original names."

Is it true? Has anybody checked?
