Constant crashing; I think Mozilla on my new Windows 7 thinks it's still operating in XP, although I'm not sure, being computer challenged.

Question

Ever since I started using Mozilla Firefox on my new Windows 7 computer it has crashed -- sometimes a few times a day, sometimes every ten minutes. I will copy the error message details at the end of this, if I can. I have tried numerous technicians and no one has been able to solve it. (I did reset Firefox more than once.) Just today, right clicking on the Firefox icon and going to compatability, I discovered that "Windows XP" was in the window instead of Windows 7. With the help of a Frontier technician (my internet provider) I changed that from Windows XP to Windows 7. We rebooted the computer, hoisted up Firefox, right-clicked on the icon, and sure enough it said "Windows 7" in the compatability window. However, after a short while Firefox crashed again. Right-clicking on the Firefox icon, I saw that it had reverted to "Windows XP" in the compatability window. Questions: Would Firefox's confusion about whether it was on a Windows XP or a Windows 7 computer cause crashes? Why would Firefox's compatability window revert from Windows 7 back to Windows XP? I have a theory, but I am not an expert: A local technician came in and transferred my Firefox from my WIndows XP computer to my WIndows 7 computer. I don't know whether he installed Firefox from your website or simply transferred the program from my XP computer. However, I asked him to keep my bookmarks. I have an icon on my Windows 7 computer: "Old Firefox Files." I thought that these files (there are four of them, all containing pretty much the same thing) were just my bookmarks, but looking at them today, it looks to me as if they contain the whole Firefox program from my XP computer. My inexpert theory: Firefox is reverting from WIndows 7 to Windows XP because my transferred bookmarks are XP-based. A Frontier technician today suggested I uninstall and re-install Firefox. Sounds like a good idea to me, however I am afraid that my old bookmarks will again confuse Firefox about whether it's in an XP or Windows 7 OS. Bookmarks are essential to the way I use my computer. In fact, many technicians suggested that I use Chrome instead of Firefox, but Chrome does not have an easily accessed bookmark list, like Firefox does in its vertical bookmark window. (Also, I would rather not have anything to do with Google.) Of course, I may be completely wrong about it being my bookmarks and the files transferred from my XP that are screwing up Firefox. Basically: Constant crashes and error messages; compatability window reverts from Windows 7 to Windows XP for some reason; bookmarks and other old Firefox program files have been put on this Windows 7 computer. What do you think I should do to keep Firefox from crashing?
Here (hopefully) is the error message I get when Firefox crashes. It crashes no matter what website I am on at the moment:

Your whole bookmarks story is very confusing to me. Perhaps someone else can explain that better. :)
Can you give me your crash reports?
#Enter ''about:crashes'' in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
#Copy the '''5''' most recent Report IDs that start with '''bp-''' and paste them into your response here.
