Works perfectly. Right-click on the page => Rename. Doesn't ask for permission, except for private browsing pages

Exactly what I want -- IF it worked.

Left or right clicking on either the tab or the page does NOT result in an option to rename the tab.

Maybe a set of instructions would solve the problem.

No-frills tab renamer. I'll give 5 stars if you fix the bug where pressing "cancel" on the popup renames the tab to "null". Should be easy to fix.
I read the source code and I suggest something like this:


var ttl = prompt("Enter new title");

/*Only renames tab if prompt returns a "truthy" value, aka not an empty string, null, undefined, etc.*/
if(ttl){
document.title = ttl;
}
