Firefox Portable

I keep getting prompted to update my copy of FF. Can i? or will this effect the functionality of PFF?

When ever I load Portable Firefox with ANY theme, or even no theme a red ^ appears under the status bar along with a huge space(about 15-20% of the screen) I used to have portable firefox, and it worked fine. I tried deleting the profile, and reloading it. I also reinstalled. Is this system spacific? How do I fix this?

I like to use my bookmarks.html as my home page, but everytime I use a computer with a different configuration of drives, the USB device letter changes.

What relative path can I use in Tools/Options/General/Location(s): to make my "file:///e:/PApps/PortableFirefox/profile/bookmarks.html" truly portable?

Is there anyway to force the flash plugin to display the animations in a larger format? Perhaps this is a problem with regular firefox also but I am only using PFF so I thought it best to ask here. I use some flash animations to show my class information and I would like to do it using PFF but it displays animations at too small a resolution even though I am projecting the image onto a large screen. I also would like to get some colleagues to switch to PFF but I think the flash glitch would be a deal killer. Here's a site so see what I am talking about: http://addictinggames.com/logicproblems.html. View the site in PFF and then in Internet Explorer and you should see a big difference. At least on my machine that is the case.

Is it possible to move the profile directory for PFF? I tried running PFF with the -p switch and nothing happened.

This is probably a very basic question, but I don't know anything about programming, etc.... so,

can anyone tell me how to combine two bookmark files. I used to use one copy of Firefox on my work computer and one on my home computer, but now I'd like to use just one copy on a Jumpdrive. I've already moved all the work bookmarks to it, and now I need to move the home bookmarks.

Thanks,

Ok, I am probably missing something fairly basic here.
I am trying to make some edits to userChrome.css for my copy of PortableFirefox. I've tried placing the edited file in:
PortableFirefox\profile
PortableFirefox\profile\chrome
PortableFirefox\firefox\chrome
PortableFirefox\firefox\defaults\profile (didn't think this would work but tried it anyway)
PortableFirefox\firefox\defaults\profile\chrome (didn't think this would work but tried it anyway)

I searched the forums and did not find anything about anyone else having trouble with this.

Any suggestions? Here is the code I am trying to put in my userChrome.css:

I'm getting bookmark backup files written every time I run portable Firefox. They are written in the bookmarksbackup folder under the profile folder. How do I disable this? I don't need to have them backed up and I don't want a bunch of junk written to my USB drive.

Hello

I've installed Portable Firefox and portable Thunderbird on my USB stick, and I use them mainly on a PC which previously has the desktop version.

when I uninstalled Firefox from this machine it obviously lose the HTML file association with Firefox. I Like very much to read RSS feeds titles in Thunderdbird and then open the body in Firefox but seemed to me that with the portable version it isn't possible anymore. Yesterday I register portable firefox as the default browser and everything seemed to work the old way, but this is not true: when I launch firefox with PStart I get full bookmarks, extension and settings, when I launch from Thunderbird I don't get the same configuration...

I've got a whole bunch of search engines ("searchplugins" folder) installed. I copied the folder from my HD. However, nothing shows up in the pFF search bar. I have no icon and the drop down list is empty.
Is there some file somewhere I need to reset?
