Hallo, since the update of Firefox for Android to version 63.0.2 I have a black logo frame around the Firefox icon instead of the light one. I'm using a Samsung Galaxy S7 with Android 8.0.0. and a Samsung Galaxy S10 with Android 9.0.0. On the Huawei P10 of my girlfriend it's exactly the same. What is the reason that for and how it can be fixed? May an update is needed? Thanks a lot in advance and kind regards, K. Beker.
