Firefox Portable

I'm having an unusual problem that affects P-FFx intermittently on my work machine.

Here is the situation. I can run P-FFx from my thumb drive on my work (XP) machine, surf, etc. Everything's fine. But at some point, if I exit and try to re-run it, it crashes on startup with the following error:

Title: XPCOM:EventReceiver:firefox.exe
Message: The instruction at 0x007FDC8F (not sure if this changes) referenced memory at 0x007FDC8F. The required data was not placed into memory because of an I/O error status of 0xc0000185.

Now once I get this, P-FFx will always crash on startup, even when run it in safe mode. Removing and re-inserting the thumb drive also does not help. There are no copies of Firefox or anything like Acrobat Reader hanging around, according to Process Explorer. It just won't run again.

I Downloaded FirefoxPottable so i can use it at school but my schools admin has blocked firefox from rnning. To fix this i simply have to rename the firefox.exe file but then wen the FirefoxPortable.exe File Searches for the file it cant find it. Has anybody got any idea what file i would have to modify to get it to work?

ok ya i have this program cuuse its portable but it not. the extenions that i down load don't seam to move With me. why is that i instail them on the/ under the same file and the firefox app. when i go to a differnt pc there not thire. why em i doing wrong cause that why i like firefox cause of what it dose.

I used a previous version of FF on my Kingston 1GB Elite and it was fast; you could barely tell you were running off USB flash. It got noticeably slower so I decided to rebuild my Kingston. I started from scratch using 1.5.0.6 and it is slow. I noticed that the cache was set ot 50 MB so I set that to 0 to minimize writes; I thought that John had set the default to 0 on previous builds. I also turned off auto updates. Start up time is also a minute or more. It used to start up in a few seconds before.

The only extensions are DOM, Google Toolbar and Scrapbook.

Saving a bookmark takes minutes! Sometimes FF becomes "not responding" but will eventually come back.

Hi, the title says it all. I can't find any parent.lock file to delete, but I just cant get it to start. the regular firefox link in the app folder works though... any ideas? I sure miss my installed toolbars and tab manager

I know that it's easy to check to see which version of Firefox I'm running (Help>About Mozilla Firefox). How/where do I check to see which version of the Portable that I'm using? Or is this actually one and the same?

Am I correct in that when I install the FFP, it installs the Firefox application itself and a Portable version/extension/whatever?

I read that it's okay to let Firefox automatically update itself. Which is what I'll do to move from version 1.5.0.6 to 1.5.0.7.

Is it only when I update the Portable application that I need to make a copy of the profile folder?

Just trying to clarify the version of the application components and when/how to update/upgrade which portion. I know that Firefox itself is up to 1.5.0.7 (I received the pop-up notifier), but I see that FFP is still at 1.5.0.6--thus my need to clarify whether we're talking two components that can be two different versions or if they're one and the same.

Just wondering if it is possible.

Portable Firefox works just fine without any extensions. But when I
eventually installed upto 7-8 extensions it ceased to startup on a
different computer. Instead the windows Task Manager shows Firefox.exe
at 9,000KB of Memery usage continuously. Ultimately, I had to move the
extension folders to some other directory and start firefox without
any ext. Then if I install the extensions it works. But it reappears
on a different system and so on.
The extensions I use are following:
1. DownThemAll
2. ScrapBook
3. Google Toolbar
4. IE View
5. Video Downloader
6. Stumble Upon
7. Orkut Scrap Easy

"Another instance of Firefox is already running. Please close other instances of Firefox before launching Portable Firefox."

The "FirefoxPortable.ini" file has an entry to allow both "regular" and "portable" FF to run simultaniously, by changing the "AllowMultipleInstances=" to TRUE. This TRUE flag will create this annoying error message in FFP, if I already have a FFP open and try to open a new instance via a windows shortcut. It will complain, that an other firefox is already running, and I should close it first.

If I leave this flag the default "false", then the error is gone in FFP, but suddenly you can not open the regular FF (if FFP is open), because the same error will appear.

... Can't wait for John and the good group to release the next portable version!

THANK YOU ALL!
