Firefox 80: HTTPS-only Mode in Settings

Mozilla added an optional HTTPS-only mode to Firefox 76 Nightly back in March 2020. The group’s engineers have now added the mode to the settings of Firefox 80 Nightly, and it’s possible that customers of different Firefox channel variations, e.g. Firefox Stable, will have the ability to configure the mode as soon as their model of the browser is up to date to Firefox 80.

HTTPS-Only Mode is designed to implement HTTPS on websites. It works equally to HTTPS Everywhere and different HTTPS improve extensions for browsers in that it makes an attempt to improve HTTP connections, that aren’t safe, to HTTPS connections, that are.

The core distinction between the native HTTPS-Only Mode and extensions is that Mozilla’s implementation makes an attempt to improve each HTTP connection to HTTPS.

HTTPS Everywhere makes use of an inventory for the upgrades that rewrite connections on websites which might be opened in the browser.

Firefox’s HTTPS-Only Mode applies the improve to all HTTP connections, even when an HTTPS possibility just isn’t out there; this may occasionally result in loading errors that may vary from websites not loading in any respect to content material on the location changing into unavailable.

Firefox informs the consumer if the whole website couldn’t be loaded as a result of it doesn’t assist HTTPS. The similar just isn’t true for components that might not be loaded on a website, although.

Up till now, Nightly customers needed to set the worth of the choice to TRUE to allow the function in the browser. A worth of FALSE, the default, disables the HTTP to HTTPS improve enforcement in the browser.

Starting in Firefox 80, that’s not essential however nonetheless out there. Mozilla added choices to manage the browser’s HTTPS-Only Mode in the choices.

  1. Load about:preferences#privateness in the browser’s handle bar and scroll all the best way all the way down to the HTTPS-Only Mode group.
  2. The function is ready to “Don’t allow HTTPS-Only Mode” by default.
    • Switch it to Enable HTTPS-Only Mode in all home windows to allow it in every single place, or
    • Switch it to Enable HTTPS-Only Mode in personal home windows solely, to solely allow it for personal searching.
  3. A restart just isn’t required.

When you allow the choice, Firefox will rewrite HTTP hyperlinks to HTTPS robotically.

Closing Words

When Mozilla launched the HTTP improve mode in Firefox 76, I concluded that it may very well be helpful in some conditions, e.g. when utilizing profiles in Firefox and utilizing one of many profiles for safe actions equivalent to on-line banking.

The draw back to enabling the mode is that it could break performance on some websites, and a few websites totally. Since there isn’t a merely “flip off mode on this web page” possibility, it’s fairly cumbersome to cope with the problem when it’s encountered.

I discover it puzzling that the choice is added to the browser’s preferences, contemplating that Mozilla’s stance in the previous was to restrict consumer publicity to settings that would probably impression the accessibility of web sites.

I feel it will be higher if Mozilla would combine HTTPS Everywhere in the browser, perhaps even with an choice to implement HTTPS in every single place. The extension is already included in the Tor Browser by default.
