A problem with compatibility with Office 2010 files
I have a problem with opening downloaded files xlsx, docx, etc. by default downloadmanager of Firefox. I have installed Office 2010 (previously had 2007). Firefox extension detects these files as zip archives. (when I was in 2007 there was the problem).
Change the default application for the file (for example, the EXCEL xlsx Office14 directory ...) to change the default application for zip files and other archives (in my case, I installed 7zip 64bit)
Deleting the file mimeTypes.rdf does not help
Operating System: Windows 7 Professional 64bit.

If the website in question is publicly accessible, it would help if you'd post an example link.
If Firefox is identifying files as the wrong type, then the server is probably sending an incorrect MIME type. Use the Web Console to examine the Content-Type response header for the file request in question.
Also see the following article.
With which content type does the server send these files?
- Live Http Headers: https://addons.mozilla.org/firefox/addon/live-http-headers/
Live Headers shows this:

also i have try at the begining the tip from "Change what Firefox does when you click on or download a file" and the result was that, when i change for e.g xlsx file firefox try to open zip files by excel, when i hange for zip extensions, firefox open Excel files by 7zip.
I didn't have this kind of a problem when i have used Office 2007. The problem occures with 2010 version

The Live Http response clearly shows that the server sends this file as a ZIP archive (application/zip)
- Content-Type: application/zip; charset=binary
In such a case there is not much to do about this apart from contacting the website and ask them to change the content type to one that is more appropriate or maybe better leave out that specific header as there is also a Content-Disposition header and Content-Transfer-Encoding header send.
- Content-Disposition: inline; filename="Ap20- praca_telefony.xlsx"
Content-Disposition: inline; filename="Ap20- praca_telefony.xlsx" Content-Description: Ap20- praca_telefony.xlsx Content-Length: 25907 Content-Transfer-Encoding: binary Connection: close Content-Type: application/zip; charset=binary
When writing the site owners, you can point them to the following page, which details the correct MIME types to use.
If they refuse to fix the problem, you can use the following extension to override the Content-Type. It's intended for advanced users, who know how to compose rules using regular expressions.
force Content-Type it could work, but unfortunately the the files from www on which problem occures are downloaded by some script. The address of file looks like:
and i dont know how to wrote an expression wchih will work only with xlsx files.
"/(.*?)10\.0\.0\.3(.*?)\.xlsx$/i" is not working
"/(.*?)10\.0\.0\.3(.*?)" - is chanfing for all zip files (so xlsx files are opened by Excel, but zip files also)....
