/**
 * Bug 1472075 - Build UA override for Bank of America for OSX & Linux
 * WebCompat issue #2787 - https://webcompat.com/issues/2787
 *
 * BoA is showing a red warning to Linux and macOS users, while accepting
 * Windows users without warning. From our side, there is no difference here
 * and we receive a lot of user complains about the warnings, so we spoof
 * as Firefox on Windows in those cases.
