Fired when a browser action icon is clicked. This event will not fire if the browser action has a popup.
To define a right-click action, use the
contextMenus
API with the "browser_action"
context type
.
browser.browserAction.onClicked.addListener(listener)

BCD tables only load in the browser
callback
Function that will be called when this event occurs. The function will be passed the following arguments:
tab
tabs.Tab
. The tab that was active when the icon was clicked.
OnClickData
An object containing information about the click.
modifiers
An
array
. The keyboard modifiers active at the time of the click, being one or more of
Shift
,
Alt
,
命令
,
Ctrl
，或
MacCtrl
.
button
An
integer
. Indicates the button used to click the page action icon:
0
for a left-click or a click not associated with a mouse, such as one from the keyboard and
1
for a middle button or wheel click. Note that the right-click is not supported because Firefox consumes that click to display the context menu before this event is triggered.
When the user clicks the icon, disable it for the active tab, and log the tab's URL:
browser.browserAction.onClicked.addListener((tab) => {
// disable the active tab
browser.browserAction.disable(tab.id);
// requires the "tabs" or "activeTab" permission, or host permissions for the URL
console.log(tab.url);
});
