Facebook with Malformed URLs causing issues with Firefox

It appears that I'm the only one experiencing problems with Facebook while using Firefox v3.5.9 (yes, I know that 3.6.x is available but upgrading to the newest version is not supported by F5 Networks plugins to establishing a VPN via Firewalker).

Anyways, just so you know I'm not talking crazy, I went to the main URL of Facebook:

http://www.facebook.com

Now I click on the 'Messages' link on the left sided menu and this is the resulting URL:

http://www.facebook.com/#!/?sk=messages

Now, I'm going from messages to my 'Profile' link that's on the top right corner of Facebook and the resulting URL:

http://www.facebook.com/#!/johnhighway?ref=profile

Note the malformed URLs.

In some cases, I go to my photo album:

http://www.facebook.com/#!/johnhighway?v=photos&ref=profile

Click on a specific album:


http://www.facebook.com/#!/album.php?aid=27439&id=503264990

And the click on the "Facebook" logo to head back to the main page:

http://www.facebook.com/?ref=home#!/?sk=media

What's up with that?

This malformed URL is plaguing my ability to accept new friends, gifts, etc. Now this appears to only affect Firefox, however the malformed URL also appears on Internet Explorer but IE is apparently more forgiving and not as strict. So, I'm having to switch to IE just so I can respond to requests but I would return to Firefox just so I don't have to deal with all the ads.
