remove microphone from widget on android

[rcrosser]

Using firefox on samsung phone. The widget to take me to the firefox search input has a microphone. I don't use Google voice search,  and have it disabled.  Still if I touch the mike icon accidentally,  google appears and tries to get me to give voice permission. I keep the icon at single width, but in landscape the icon widens and the mike appears. I don't notice,  and touch it accidentally. It would be great if the mike could be completely disabled or removed.
