Hey,
I know this is a common problem that people cant install some mods, or cant install *.xpi files etc. However, nobody seems to have given an exact error they get. I installed PFF onto my personal drive in college (I cant install anything anywhere else). However, on launching an extension or skin install half way through the procedure this error appears;
"Firefox could not install the file at [URL to extension] because: script error".
Sometimes its installed after I re-boot tho.
Any ideas? Its the same error when I go to "File > Open" and launch the xpi file I saved on the PC.
Cheers and good job

That's an actual error in the script inside the XPI. But it could (in theory) be an issue with the cache disabled... though that is doubtful.
Sometimes, the impossible can become possible, if you're awesome!
Somehow I doubt it. Why would so many of my extensions and skins on download get the SAME error each time, and work after install?
The error does not appear in the normal version of Firefox..
And Cache was enabled
If you enabled cache, then you're using regular FF with no changes within it. I'd say your profile may have an issue as I've never seen the error you describe in the nearly 2 years I've worked on Portable FF except once when a corrupt extension was posted on addons.mozilla.org.

I have also tried installing some extensions to my portable firefox as well and I am met with the same issue. I've tried searching the net for solutions and most people recommend clearing the cache on pff. I currently have my cache set to zero.
A couple of extensions that I am keen to install are
Tab Mix Plus
Web Developer
I have tried various methods, downloading the extension from the zite, dragging the extension file onto pff and even opening the extension with pff.
Any help or feedback on this issue would be greatly appreciated.
I would recommend against installing tab enhancement extensions on Portable Firefox if you're running it from flash media. They tend to write to the drive constantly, which not only shortens the life of the media, but slows down PFF to no end, even on USB 2.0.
To John, Bruce, et al :-|
Is this program not a good idea for Portable Firefox? What if you shut off the Session Manager and the Crash Recovery options? Does it still write to the USB drive excessively and/or impact performance?
I found some more posts here by searching on "TabMix" instead of "Tab Mix" and it looks like shutting off Session Manager as well as Crash Recovery is recommended.
With those two functions disabled, is TabMix Plus no longer negatively impacting the drive and/or Portable Firefox?
Thanks.
I don't think so at that point. Give it a shot and see. The worst thing it'll do is slow down browsing, and you can always disable/reenable it to compare with it on and off.

I use tabmix and have both turned off, and have no problems.

Thanks John and Deuce for the quick replies.
I have turned both the above functions off (I turned off the above two functions, told it not to restore or save on browser start and exit respectively in the "Start/Exit" tab, and cleared all the check boxes in the tabs for "Restore" and "Preserve").
