Firefox Crashes when downloading/uploading/importing bookmarks

Question

Firefox immediately crashes whenever I try to download files, upload files, or import my bookmarks from a file. Basically, if I try to do anything that would require navigating a folder to select a file the browser crashes, and it doesn't let me submit an error report either. I haven't had any problem simply dragging and dropping files to upload them, but I pretty much can't download anything at this point unless I drag and drop image files or force all downloads into one folder. The problem persists even in safe mode.
I recently reformatted so this is a fresh Firefox install, and I have made sure Vista was completely updated, and I've updated my drivers as well.

I found out that an option in Microsoft File Explorer caused the crash.
To solve this:
- Go to "Organize"
- Choose "Folder and search options"
- uncheck "Automatically expand to current folder"
Note that this setting is on the " General" tab of "Folder Options", which you can also access from Windows Control Panel.
