Cette extension fait ni plus ni moins ce qu'elle est sensée faire.

Perfect for users who don't have or don't want to install Firefox for Android (Nightly), or change web browser.

Works as intended in view-source tab.

You can see elements related to user access if you logged in, unlike online source viewers (public view, no sign in).

Thank you for bringing to addon to Firefox for Android!

Great for finding CSS selectors when tweaking a site's CMS while not at computer.

Edit: neat addon, works flawlessly on Android. Developer is nice and responsive if an issue is reported.
