There are quite a few add-ons out there that let you remove and edit page content before you print it, but most of them are either too complicated or come with too many options. Remove Temporarily is a simple, but handy Firefox add-on that adds a Remove Element button to the inspect element toolbar. This button conveniently allows you to remove parts of a webpage of your own choice. Remove Temporarily can be used to remove parts or items on webpages before printing or for reading purposes. It helps you get rid of all the unwanted content, such as advertisements, sidebars and more. Moreover, the page goes back to its original form once you reload it. After installing the add-on, simply right-click an page element that you want to remove and select Inspect Element option from the right-click context menu. As you do this, the inspector tool will appear at the bottom of the page with the Remove Element button. Click this and you’re good to go!
The add-on is quite useful for printing or viewing purposes and is neatly integrated into the Firefox Inspector tool. Once you’ve installed the add-on, simply right-click on an element that you want to remove and a highlight box will appear over the element. Then, click the Remove Element button in the toolbar and the element will instantly be removed from the page, allowing you to view or print the page in a clutter free manner. Also, users should note that only one element can be removed at a time.
This is obviously an add-on meant for advanced users since not everyone ventures to the Web Inspector. Developers will, very likely, find it useful but there is a problem with getting the removed elements back; you have to reload the page to do so. Assuming you’re a developer working with Firefox’s develop tools, it is highly likely that removing an element from a page isn’t the only change you’ve made but, to reverse it, you have to kiss your changes goodbye. The add-on’s developer should consider adding a feature the keeps track of the removed elements and allows the user to select any one of them to bring back. The add-on is great for supplementing the default tools which allow you to edit the HTML of a page but provide no way of easily removing an entire section at once.
