New Modem install message

[Jm4steam45]

Installed a new Arris SBG8300. No issues. However this FYI came up in gateway..

The version of Mozilla Firefox you are using is unsupported. Your Gateway's web interface has been tested to work with the minimum version 63.0.3. you may experience issues using the pages.

Hope this helps.

Do you know what version of Firefox you are running? You can check the Troubleshooting Information page -- the first section has detailed information on your Firefox version. To open that, either:

• "3-bar" menu button > Help > More Troubleshooting Information
• (menu bar) Help > More Troubleshooting Information
• type or paste about:support in the address bar and press Enter

In the first table, look for the Version row. The current versions are either 101.0.1 (standard release) or 91.10.0esr (extended support release). I assume you aren't running a five year old version...

Next, look for the User Agent row. This is how Firefox identifies itself to websites. As an example of what you might see here (for 64-bit Windows):

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:101.0) Gecko/20100101 Firefox/101.0

Does yours look like that?

Finally, consider whether Firefox's identification might appear different to websites because some intervening agent is modifying it. You can check that using a site that shows what your browser sent it. As an example, this secure connection test page shows your User Agent in small print below the main heading:

https://clienttest.ssllabs.com:8443/ssltest/viewMyClient.html

Does that look different than what you see inside Firefox?

If it's different, there are a couple possible reasons:

(1) The hidden privacy.resistFingerprinting option will known your version down to the current extended support release.

(2) Some add-ons are designed modify or randomize your user agent -- that usually is obvious from their name.

(3) An external security program may modify your user agent. For example, Avast/AVG AntiTrack can add some crap at the end which confuses sites that use the last part of the user agent string to figure out what browser you are using.

One other thought:

I assumed this device, being new, had new firmware. But that might not be true, they might not have updated it for years. Devices with older firmware or sites with older software may not be ready for 3-digit version numbers on browsers. Firefox has an option to globally tell sites/devices that it is version 99. I think the only way to confirm whether this is the issue with your device is to test the change and see what happens. Here's how:

(A) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. Please keep in mind that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.

(B) In the search box in the page, type or paste network.http.useragent.forceVersion and pause while the list is filtered

(C) Double-click the preference to display an editing field, and change the value to 99 then press Enter or click the blue check mark button to save the change. (This change will be reflected on the User Agent line of the Troubleshooting Information page.)
