Here is a free Firefox add-on to edit URL parameters in Firefox sidebar. It is named as “URL Envy“. All the keys and values of a URL are visible in the sidebar and then you can customize or edit those items as per your needs. Once you made the changes, press enter and it is reflected in the webpage URL. That also means that URL is updated/refreshed with the new parameters and you also don’t have to leave the tab to check the URL.
Another interesting feature of this Firefox add-on is you can remove any keys/values from URL. Moreover, new keys/values can also be added and then you can use URL with the new parameters. The add-on also lets you change or edit the base URL, so it has multiple benefits.
In the screenshot above, you can see the sidebar of this add-on where base URL and URL parameters are visible.
