SonicWall TZ215 admin login from across the VPN using Firefox doesn't work, Chrome/IE does

We have two SonicWall TZ215's running SonicOS Enhanced 5.8.1.8-42o at two remote locations.  We have a VPN setup and I have enabled the features in the VPN tunnel to allow HTTP, HTTPS, and SSH remote administration.  It works properly using Google Chrome 36.0.1985.125 and Internet Explorer 11.0.9600.17126.  

However, it will not allow me to login using Mozilla Firefox 31.0.  It gives the me the login on Firefox, then I fill in the password, and it attempts to login but goes right back to the login screen.  Mozilla Firefox is my preferred browser and I have been using Chrome to administer the SonicWalls for now but I am just curious as to why the login doesn't work.

In testing, I have removed the Self-Signed SSL Certificate from inside of the Firefox browser at the following location but it didn't make any difference on login capabilities:
Options - Advanced - View Certificates - Certificates - the remove the SonicWall certificate for that specific IP address
Then at next login, I need to click "I Understand the Risks" and then I Confirm the Security Certificate and Permanently Store it to get the login.  This is the login that just keeps looping around after I enter the details and click login.

I just find it odd that it doesn't work in Firefox and wanted to see if anyone else experienced this issue.  I have done some Google searches and haven't had any luck finding others with the same issues or they haven't documented it well enough to be found.  For the record, I haven't tried to login locally (not over VPN) using Firefox because I don't have a local computer with Firefox but I don't believe that would be related anyways.

Have you tried allowing administration from the outside world, then tried logging into the Sonicwall without the VPN?

Yes, I have that turned on for both firewalls and one works from the outside in Firefox and the other does not.  I am one for four for working in Firefox.  TZ215#1 - works outside, not on VPN in Firefox.  TZ215#2 - doesn't work outside or VPN in Firefox.

I am just more curious as to what would be causing this.  Perhaps it is the self-signed certificates that they use.

Sorry... meant to ask if you had tried updating the firmware. I would say try 5.9, but it is a mixed bag.

The one that works on WAN but not VPN is on SonicOS Enhanced 5.8.1.8-42o.

The other one is using the same version actually - SonicOS Enhanced 5.8.1.8-42o.  This one has a note at the top "New firmware version 5.8.1.14-48o is available".  Maybe I should do that and see if that helps.

The only issues I know of that were limited for sure in 5.9 was the ability to merge the WIFI and LAN networks together that I experienced on another SonicWall TZ 100W.  I may see about possibly upgrading to a newer version after hours of course.

Our local side of the VPN is a SonicWall NSA 220 with SonicOS Enhanced 5.9.0.3-117o.  I could try and match that version and see if that helps.

Alright. Be careful... on some firewalls, there is a bug with the content filter acting very screwy when certain 5.9 firmware is loaded, forcing you to use one of their hotfix releases. I would try to stay within 5.8 for now, then work from there if needed.

Yeah, I will just stick with my 5.8 that is working.  But maybe it is just a bug in the release I have.  The other big update on the 5.9 is the word Dell and the whole GUI is a bit cleaner but that's alright, not necessary.  Thanks for the advice.
