Usage

This package exports various utilities. Each tool has its own entry point, so you only import what you need:

import doesTabExist from 'webext-tools/does-tab-exist.js';
import getExtensionUrl from 'webext-tools/get-extension-url.js';

• doesTabExist - Checks whether a tab exists.
• getExtensionUrl - Generates a URL object for a resource bundled with the extension.
• getTabUrl - Get a tab or frame’s URL even with limited permissions.
• queryTabsByUrl - Get the IDs of tabs matching URL patterns.
• setActionPopup - Sets the popup URL (or removes the popup) depending on the current tab.
• createContextMenu - Creates context menus without pain.
• devToolsEval - Wrapper around the DevTools eval function that throws proper errors.
• addOptionsContextMenu was moved to webext-bugs.
