Here is how you can have Firefox’s JavaScript Console open in a sidebar:
- Click on the Bookmarks menu and select Manage Bookmarks…
- Click the New Bookmark toolbar button
- Enter JavaScript Console as the name
- Enter chrome://global/content/console.xul as the location
- Check the Load this bookmark in the sidebar checkbox
- Click OK
Now you have a bookmark that will open the JS Console in a sidebar! For Firefox fans there is little doubt that this nifty feature is going to save untold man-hours and raise productivity. I just love these additional pieces of functionality that keep cropping up in Firefox, especially those that are going to actually help make my job easier. Now where do I send the check?
