Currently using ccleaner browser Version 96.0.13468.96 and I cannot mute a single site when multiple tabs are open with at least 2 tabs playing sound.
When I right-click the tab I want to mute, the action results in muting ALL tabs.
I can reproduce this regardless of how many times I restart ccleaner browser (and remove all instances from memory).
As a side note, it would be nice if left-clicking the speaker icon on the tab would mute that sight only instead of having to move my mouse curser to "mute site like other chromium-based browsers.
Regards.
