How do I open a file with the .mab extension?

I recently updated my older computer from Windows XP to Windows 7 and forgot to print out my address book from Thunderbird. I did save the file on a thumb drive and when I try to open that file, my computer does not recognize the file ending .MAB and will not open it. When I tried to open it by adding Thunderbird to the Windows list, it puts the file in an email and still will not open it. Please help! Thanks in advance for your help.

sfhowes Your response was helpful in that it made it clearer to me how I should go about doing this. However, when I did as instructed, it ended up without actually opening the address book. I could see the file in Explorer in the Thunderbird folder and clicked on it and it goes immediately into a new email as an attachment. Color me confused, once again. Sorry to be so silly or obtuse, but is there something obvious to you that I am doing wrong? I really do appreciate this help because it made the functions clearer to me & gave me more understanding of the program. Smiles, Shurrwill

sfhowes, Thanks very much for all your help. I still have not been able to make it work & I am not really sure what I am doing wrong at this point. <Sigh> Really want to find all this stuff, but I guess I will have to rebuild my address book. Unfortunately, all my passwords were in there as well. Oh well, that is what I get for not simply printing the damn list, right?  :) Thanks again! Shurrwill

I suggest you go into the file association in windows control panel and remove the file association you made for MAB files.

Note here that until your fix the mess you made in file associations, double clicking an MAB file will see stupid things happen.
