You are most welcome

event.data === tab-exists. is these keywords are from broadcast channel API?

[@deeecode]

the event (when a message is sent) is an object that has the data field. this field contains the string passed in the postMessage method, which is from the broadcast channel API

[@Shashwat-000]

@@deeecode Thankyou

[@AbhijithAS-r8z]

which browser ?

[@InfoVerseNetwork]

Maybe arc

[@abhishekpratap05]

ARC

[@deeecode]

it's arc...i like the split view, tho I doubt if I'd be using the browser for a long time

[@leocarvalho8051]

Just a suggestion. Disable title video auto-translation. It is really stupid and is killing your views.

[@deeecode]

thank you so much for this. i thought it would be a helpful thing but just realized how it may not.
