Firefox Portable

Trying to install extension with .xpi.
The Plugins window doesn't allow installation. I entered the local address on my hard drive into the address bar and showed me the files in the directory. Double clicked the .xpi I want to install and gave me the option to install.

It started to insall but gave me an error -
"Could not install the file:
location
because: Install script not found
-204"

What is this Install script, and where do I find it?
Thanks

Hey, I am running Firefox on my flash drive, with Portable Apps, and it's quite slow. The USB drive is 2.0, and the computers are 2.0 high speed so it's got to be firefox.

it's not a problem, works at home great but when I am on the go it's a little slow loading pages and typing stuff. I was just wondering if there is a tutorial on how to make firefox run a bit faster, without adding any plugins.

Thanks!

It is not possible to connect it by "Time out:The Server takes too long time to connect."'s being displayed when trying to hook up to the Internet though FFPortable3.04 is used.
Someone, please teach causing.

I have downloaded the adobe flash plugin. It is an exe file that executes, but doesn't install into my firefox portable on my usb drive.

How do I make this work?
Thanks

I have recently used my portable version of Firefox on another computer which already had Firefox on it's HDD. The computer I used also had AVG Free AntiVirus installed on it with AVG Security Toolbar installed on it.

When I started Firefox portable from my USB key, The AVG security toolbar was installed on my version of Firefox portable. But when I went back to my home machine, the toolbar was no longer there.

Today, I unplugged my Titanium SanDisk Cruzer and an error message came up quickly for only a second saying "corrupt file" or something to that effect. When I plugged my drive back in and opened Firefox Portable, all of my bookmarks on my bookmark toolbar had vanished and there is nothing in the folder either. The last time I backed up was in Sept. Is there anyway to recover these files and what do you think happened?

I can't explain the source of this problem, or recover from it.
Running 2.0.0.16 everything worked as I wanted it: as sites are visited, the directory Data/profile/Cache grows and grows. I upgraded to 2.0.0.18, set everything under Tools -> Options as for 16 but, try as I might, I can't get the Cache to grow. I have "Always clear my private data when I close Firefox" unchecked, and "Use up to 3072 MB of space for the cache" (not 0). But the directory remains stubbornly sparse.

so here is my issue:

Is it possible to use multiple user profiles in FireFox portable?

Hello,

First of all thank you for the excellent work provided through these "portabilised" apps.

I have not found any topic relating also let me ask the question: is it possible to change the location of the "profile" folder of FireFoxPortable (cl. 3.0.4) and if so how?

Thank you

Alain
