Not everyone knows that the Mozilla Firefox browser has several secret menus hidden inside which contain configuration settings, statistics, usage information and jokes . These are the " About " menus which cannot be accessed by pressing a button but by typing a command on the address bar.
Simply write the word about in the box above, where the URLs of the websites appear, followed by the name of the page to be displayed.
So let's see the main about pages of Firefox to open the browser's secret menus, sometimes useful for improving and personalizing navigation and among which some very curious pages are hidden.
1) about: about allows you to view all Firefox About pages and access them with a click
It is therefore a general index for quick access to these menus and information pages.
Some of them are pages that can be accessed from the normal Firefox menu buttons such as, for example, the page for managing add-ons about: addons .
2) about: mozilla is a curious and playful page where a verse from a phantom "Book of Mozilla" is written (a bit like the Bible).
The sentence that can be read on this page, also written in Italian, changes every now and then.
Mozilla's book, as we read on Wikipedia, tells about the war between Netscape and the "bad" Internet Explorer and how Firefox rose from the ashes of NetScape and became large.
Currently, on my Firefox I find written: " Mammon was sleeping. And the risen Beast spread on the earth and his followers became legion. And they announced the times and sacrificed the harvest in the fire, ..... continue"
3) about: config is the most useful page among Firefox's hidden menus.
This section contains all the internal browser parameters and the tweaks (not present in the options menu) which, if you are an expert, you can modify to customize or improve Firefox speed.
In other articles I have listed some useful changes from the About: config menu and some parameters to change to optimize and speed up Firefox.
4) about: robots is a Firefox joke.
The page writes " Welcome humans, We come in peace "
The following phrases are extracted from some films, books and Futurama: " Robots have sparkling metal backs that shouldn't be kissed ."
5) about: crashes is a very useful command, to be used when Firefox crashes and freezes.
If navigation on a tab is blocked but you can still write on the address bar, type about: crashes to send an error report and get an answer to understand the problem.
6) about: permissions shows a list of all specific permissions that have been granted to websites visited with Firefox.
They can also be modified from the various drop-down menus that can prevent the saving of cookies, the saving of the password, the sharing of the position and other things.
7) about: support brings up the same page that you can read by going to the Firefox options menu and clicking on Help -> Troubleshooting .
The information of the problems concerns all the characteristics of the computer, of the extensions installed and of the parameters possibly modified.
From a button you can open the Firefox profile folder which, as seen in the article Solutions for Firefox errors if it crashes or crashes, is the place where all the personalized settings are saved.
If you are looking for help online on a help forum or with a friend, you can press the Copy to clipboard "button to send everything by pasting the information into an email or message.
8) about: cache is used to see in which folder the Firefox cache files are saved so that it can be emptied or checked.
9) about: credits is Firefox's thanks page for all developers and people working on the project.
10) about: blank is instead the empty page of Firefox, useful to be put as the home page without opening the about: home or other websites when you open the browser.
11) about: performance is a small Firefox task manager to see the energy consumption of open tabs and active extensions.
To quickly access all the About pages of Firefox, you can install the What About extension
