pageAction.show()
Shows the pageAction for a given tab. The page action is shown whenever the given tab is the active tab.
show() overrides pattern matching, so the page action will be shown in the specified tab even if show_matches does not match the URL or hide_matches does.
Note that calling show() has no effect on a tab with no content loaded.
Syntax
browser.pageAction.show(
tabId // integer
)
Parameters
Return value
A Promise that will be fulfilled with undefined.
Examples
This example shows the pageAction for the active tab when the user selects a context menu item.
Note:
You'll need the contextMenus permission in your manifest to create context menu items.
browser.contextMenus.create({
id: "show",
title: "Show page action",
});
browser.contextMenus.onClicked.addListener((info, tab) => {
if (info.menuItemId === "show") {
browser.pageAction.show(tab.id);
}
});
