Translucent elements are transparent on Firefox and others #2
Description
All the elements with the translucent class, such as app bars and the bottom navigation, are shown transparent in some browsers, such as Firefox, Opera and Samsung Internet.
This is due to the backdrop-filter property, that applies a blur to the content below the element. Nonetheless, this property isn't enabled by default in the Firefox brower : user has to manually enable an option in about:config. See the compatibility table
