Firefox Portable

So i used this http://www.winhelponline.com/blog/register-firefox-portable-with-default... to set my portable firefox as the default application for links etc. The problem i'm having, is when i try clicking a link inside my email, i get the message:

"Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."

FireFox 3.1 required so much memory that it cannot run correctly on this machine. For example, it cannot display gmail correctly, claiming that it does not have enough memory to run scripts. I ran this test on a laptop with 512 MB of ram and running Vista Home Basic.

The local library computers run XP in 256 MB.

I have been using the portable apps suite for a little over a week - everything is working fine (Gimp, ftp,Keepass, etc,etc)I can sign in to every site that is in my browser. Recently though I have been unable to login to Facebook, where as when i first started using the portable browser I could sign in every time. Has anybody else noticed a problem like this?

PS.I deleted my password from my browser and entered it manually in a attempt to resolve the problem, but it has had no effect.

Firefox 3.1 beta 3 can be downloaded here: http://www.mozilla.com/en-US/products/download.html?product=firefox-3.1b...

I saw the link posted at http://www.neowin.net/news/software/09/03/12/firefox-31-beta-3

The main Beta page doesn't link to Beta 3 yet, but it seems that this page is live.

For some time FireFTP no longer works, and I thought it was because it was no longer compatible with FF, but should be as far as I can see.

FireFTP launches just fine, and when I try to connect to a site the logs shows that everything is fine. for example:
220---------- Welcome to Pure-FTPd [TLS] ----------
220-You are user number 1 of 50 allowed.
220-Local time is now 07:58. Server port: 21.
220-IPv6 connections are also welcome on this server.
220 You will be disconnected after 15 minutes of inactivity.
AUTH TLS
234 AUTH TLS OK.
PBSZ 0

After updating to 3.0.6 and then 3.0.7 portable, the installation would not install the add-on Foxmarks saying it is not compatible. Where did I or it go wrong.

Everytime I close down FF it defaults. [kinda] It shows all those encryption things that are only supposed to pop up once. I also cannot set any themes because as soon as I restart FF to enable a theme it just defaults. Also, I have session store enabled, but the only tabs that pop up are the main page, and the download statusbar information page.

I would like to have an easy way to backup (and restore) my current bookmarks and toolbar settings of my Firefox portable WITHOUT having to install (big) third party apps like MozBackup.

Furthermore I don't need a backup of add-ons.

Just built-in settings + bookmarks are enough.

How can I do this?

I would prefer instructions for copying files (which ?) in WinExplorer

Just have a quick question. like to use a few portable apps on a partitioned hdd, so when i want to do a fresh install i can leave the portable apps and not have to install them every time.

Well i've just done a fresh install. But when i ran firefox portable all the extensions, cookies and my bookmarks were gone.

And i was just wondering if there's a folder i need to be adding them to so they'll stick, and if i decide to put firefox onto a usb to use on a different PC, those bookmarks and settings will be saved.

Due to a power cut, the PC turned off and files weren't saved on my USB stick (using FF from within a TrueCrypt volume).
When I restarted, ScanDrive had to be run to fix some errors, now the POrtabkleApps menu loads but FF refuses to start, no error messages.
I tried reinstalling and then replacing the old folders but no luck so the problem must be in those files somewhere.
How do I keep the old data and do a reinstall? I have copied the folders: App, Other, and Data
Thanks
