What Extension Is This? (Google Cast)
I found an extra folder in the Extensions folder, a search shows results for Chrome cast (among others), but I didn't install it.
Vivaldi has it's own cast function build in. Rightclick on a website and there should be a "Cast" option.
I know, but want confirmation that this folder is part of Vivaldi or if it can be deleted.
Whatever this extension is, it doesn't show in the Extensions page.
it's part of vivaldi and you'll find it again on next update anyway
It is Google Cast, found these lines:
"Chrome Media Router feedback"
"Tell us what's happening with Google Cast."
