It also does CSS inspection well and can even change CSS rendering on the fly. Chrome has a graphical tool for debugging (like in Firebug), so you can debug JavaScript. Just right click anywhere on a page and choose 'Inspect element' from the menu.
How to Use it Most of the time it is used to Inspect Elements on a Webpage and to get the XPath of the Elements from a Webpage. There is a Firebug-like tool already built into Chrome. If you’re looking to uninstall any extensions you no longer need, start misbehaving, or were accidentally installed, head on over to chrome://extensions/, click “Remove,” and then click “Remove” again in the popup confirmation window. Once the Installation is finished, press F-12 to open Firebug tool. It also allows you to toggle individual style sheets. In addition to that it allows to create new style sheets and to import existing style sheets and apply them to the page. You’re able to choose from three options: when you click the extension, on a specific website, or on all websites. The Style Editor in the Firefox DevTools allows you to examine and edit the different CSS style sheets of a page like Firebugs CSS panel does it. After you’ve installed firebug, you can install Firepath. In the Add-ons Manager page, enter FireBug in the search bar and hit the Install button.
This is a recent update that lets people take a more granular approach to the type of data an extension can read and change. Open the Open menu and select Add-ons section. Site access lets an extension have permissions to certain sites to access site data. RELATED: How to Control a Chrome Extension's Permissions In the settings window, you can turn the extension on or off, allow it in Incognito Mode (most apps are disabled there by default), access an extension’s options, open the extension’s website, and allow site access. Otherwise, if you know which extension you want to change-and it’s already docked on your browser- you can right-click the extension’s icon on Chrome’s shelf, then click “Manage Extensions” to circumvent going to the main extensions landing page.
