To view the page source in the Firefox app on Android, use this syntax.
view-source:https://www.google.com |
This will view the source of a page on Firefox on Android. This would be a very useful tip when viewing a page on mobile. Maybe it is best to copy the page URL to the clipboard and type view-source: and then paste the URL after it.
This should be very helpful on mobile. I am using the Firefox Nightly app, so if it does not work on standard Firefox, install Nightly instead.
