Firefox Portable

When the drive letter gets changed the addon "Add to Search box" is disabled.
I found this in earlier post but didn's get any clue what to do?
Also I wanted to ask whether any addons are not portable??
Also which download manager or addon should I use to speed up donloads without any problems of portability

I've been using Firefox Portable not only on my pendrive but also on my PC, so that I don't have to remember to backup it when I'm reinstalling Windows. However there is one major issue with that solution. I set up Firefox Portable as my default browser but if I have it running at the moment other apps cannot open any links because I'm getting "Firefox is already running but is not responding." error. This of course is not the case with standard Firefox installation. Is there a way to get rid of this problem?

The link for 2.0.0.15 is not working.

I gave up on FF3 yesterday and went back to V2.
I was running FF3 on a 4gig Kingston HyperX drive, with everything turned off that has been mentioned in this forum, but I was still having slowdown/freeze problems. I monitored memory usage and it happened whenever FF3 spiked up to about 175,000k, which was often.
FF2 seems to be running about 140,000k consistently with no problems whatsoever.
(If anyone else decides to go back, remember to leave the main FF folder and the Data folder intact; delete everything else).

I'm unsure what caused this, or even if I could reproduce it, but here we go.

Just a note that this happened to me, maybe this isn't the correct place to talk about it, but I found no other... I keep my browser (of course) and many other programs on my 4GB cruzer, I often times have family and friends who have issues with their own computers and I therefore carry many adware/spyware detection programs and whatever the best free antivirus program I can find on it. Well I recently wiped McAfee off my Mom's computer and installed AVG antivirus in it's place, and at some point in all that I was running and fixing, I ran my portable firefox.

Any body have any experience with that?

When I visit BBC's player here: http://www.bbc.co.uk/iplayer/console/fivelive/

It tells me "To play BBC Radio 5 live please first install Windows Media Player for Firefox. "

In a clean fresh install of Firefox 3.0 (non portable) with no add-ons going to the following site works with no problem.

However, in a clean fresh install of Firefox 3.0 portable with no add-ons going to the same site returns the following error:

" The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.
* Please contact the website owners to inform them of this problem. "

Today while testing some software I had to restart FFP. When I tried to start it again, it showed a splash screen, but then there was only silence. After some troubleshooting I started FF directly (not the launcher) and saw a message box saying that there's a dll missing (my launcher's %PATH% changed in between).
To summarize: When something goes wrong, FF informs users about it and lets them deal with the problem. The launcher somehow prevents it from doing this, which is definitely bad.

I use the portable on the computer, its quicker when reinstalling windows.

With FF2 i could call "FirefoxPortable.exe *somewebaddress*" and the page would load in an already running FF2 (I think i set AllowMultipleInstances=True in FirefoxPortable.ini)

However, this doesn't work with FF3 - instead I get presented with a dialog box saying "Firefox is already running, but is not responding. To open a new window, you must first close the exsisting Firefox process, or restart your system."

Any idea on how to get rid of that?
