Right now im running Windows XP Professional w/ SP2 and the most recentversions of Mozilla Thunderbird and Firefox. However, by the end of the month I'm interested in moving all of my computers over to the Linux operating system (FedoraCore3 (2.6.9 kernel)). I would like to know how to transfer all of my settings over from my Windows computer over to my soon to be Linux system... For firefox all of the saved passwords, settings, bookmarks, etc... and on Thunderbird the same information except also all of the emails. Is this possible? If so, how would I go abotu doing it? I usually use MozBackUp but I learned thats not compatible with Linux so do I justn eed to transfer over some contents of some folders or what?

You may try copying your profile folders from one computer to the other. Try copying these folders:

C:\Documents and Settings\[your username]\Application Data\Mozilla ----> /home/[your username]/.mozilla

C:\Documents and Settings\[your username]\Application Data\Thunderbird ----> /home/[your username]/.thunderbird

I think that should work for you.

No, it will not work. Just think about different filesystem structure on win and Linux and you understand.
Backup your bookmarks.html - you can use it on Linux, paste it to your FF profile dir once you have it installed. Create a simple .txt file and store your passwords in. More than this? I don't think so.

hmmm crap what about emails? thats my main concern....

Same with email. You can save an existing messages, but cannot transfer your working profile to Linux. But what so big problem to set FF or TB up?

Nothing so much with configuring the settings but I have roughly 200 - 300emails in thunderbird to manage my different ventures and businesses with websites that I would prefer to transfer to my linux box

There is no problem with messages, save them anywhere and then put them into your TB profile dir.
Good luck.

how do i save them without doing it individually?

How they stored now in your system?

I imagine in the application data folder..... where they are by default with thunderbird

Great. It's just messages, single .eml file each. You can store them on CD or something, don't you? And after installing Linux and TB just copy them to your TB folder.

IN C:\Documents and Settings\

and in the application data and then uhnder my mail I see Inbox with no apparent file extension.... (I have it set to show all extesnions in windows but it doesnt show up) and then the Inbox file is 130MB and then theres the drafts folder and all of that.... but its a single file and no .eml

Wow. Sorry, man.
Ok, maybe, you can export each to a file? Like "Save as..."? I know it's a big work, but can't imagine other way to do it.

wut about copying the inbox folder to the location where TB stores mail in linux... I dont imagine it would contain any references to file locations or wut?

You can try it. I can't say nothing because i never did such things.
