My Bank of America warns me that Firefox is not supported (I use Linux)

I want to add my similar experience with Firefox on Linux to the archived discussion at https://support.mozilla.org/en-US/questions/1129022?fpa=1. Bank of America has been warning me that Firefox is not supported on the online banking site. I should use Chrome or Safari, instead. The archived question poster is using Firefox in OSX, I am using Firefox in Linux Mint 17.3, a derivative of Ubuntu. Version 56.0 (64bit).

I've largely ignored the warning across the top line of the site and continued doing business as usual without a hitch. But I have been warned that I can be locked-out without warning.

I wonder, I could falsify my user-agent string and claim to be using Wind Blows?

Thank you.

You would have to spoof the user agent and possibly the platform as well in case a website explicitly states it only supports Firefox on Windows and not on other platforms. If you only get a warning bar and want to remove (hide) it then try a content blocking extension.

You can use the Inspector to get the selector.


There are quite a few extensions that are 57+ compatible.

Fred McD, I have come to the point where next step is Safe Mode. I followed your instructions to this point and still am notified of the unsupported browser.

I launch Firefox' Profile Manager, then launch the browser in my choice of a clean profile or the one I've been using. I will experiment in the clean profile, with the custom settings for History set for keeping cookies until I close Firefox, which also clears the cache.

I will report again after the clean profile test. Fred, do you think that's a good alternative plan?

It was good practice, using my Cookie Monster add-on to keep desired cookies. (Browser default is to dump all cookies upon closing.) I watched in one tab open to the Show Cookies window to see a number of cookies there until I temporarily set the Cookie Monster to reject the bank's cookies. The Monster is set to dump all the site's cookies when I select to reject cookies and they are replaced when I set it to accept cookies on the site, in Living Color (and Black-and-White) in the Preferences' Show Cookies window. (Network television would present a program in those words back when color TVs were using the round picture tube and most people had not yet bought one!)
