The Firefox web browser ships with a boatload of internal pages that users can access to configure the browser's functionality, or look up or edit information.
Some examples are about:config, the powerful preferences listing of Firefox, about:support displaying a variety of support and troubleshooting related information, or about:downloads displaying all recent downloads.
Most experienced Firefox users know the local addresses of these pages, and open them in tabs in the browser whenever the need arises.
Not so experienced users may use the menu to do same for select pages, but it is likely that some are never opened by them at all.
LastPage is a brand new extension for the Firefox web browser that improves the accessibility of 9 internal pages in the Firefox web browser.
The add-on adds an option to Firefox to display internal pages at the bottom of the browser window, so that the window is split in two when that happens.
The upper part displays the website that is currently displayed in Firefox, while the lower part the selected internal page.
List of supported pages
The extension makes available the following internal pages:
Once you have installed the extension you will notice a new icon that has been added to the browser's add-on bar automatically.
A right-click on it displays the selection menu that you can use to open one of the supported internal pages in the browser window.
It is usually possible to interact with the data right away. If you open about:config, you can search, modify or add parameters and values displayed here. That's actually pretty neat as you may read about a new tweak on a website and while the instructions are open, open about::config on the same page to make the modification.
Another example is the bookmarks library. You can keep it open at the bottom to open bookmarks in the active (left-click) or a new tab (middle-click) right away, or to add or edit bookmarks.
The add-on has limited use on systems where the monitor height is not that large, or where the browser window is not displayed in full height for one reason or the other.
LastPage is a new add-on for Firefox, and while its initial functionality is certainly useful, it could use a couple of improvements to increase that further.
A keyboard shortcut to quickly toggle the display would be handy for example, especially for users who do not display the add-on bar in the Firefox browser.
Another would be the integration of additional internal pages, like about:cache, about:permissions, or about:memory which could be really useful in certain situations.
