Recommended Posts

Mozilla Firefox 55.0 has been released by Mozilla. The official release date of Firefox 55.0 is August 8, 2017. The new version of the web browser is already available, and will be offered on August 8 to existing users of the web browser provided that they have turned updates on.

 

Firefox 55.0 breaks compatibility with older versions of the browser and Firefox ESR. Users who want to downgrade are advised to back up their profiles prior to installing the update.

 

Firefox Beta, Nightly and ESR versions are also updated on the day. Firefox Beta is moved to Firefox 56.0, Firefox Nightly to Firefox 57.0, and Firefox ESR to 52.3.

Executive Summary

  • You cannot restore an older version / migrate to Firefox ESR after the upgrade to Firefox 55.
  • Firefox 55.0 is the first version of Firefox that moves directly from Nightly to Beta.
  • The new WebExtensions permissions systems is enabled.

Firefox 55.0 Changes

WebExtensions Permissions system is live

firefox installation permissions

 

Firefox 55 ships with a permissions system for WebExtensions. These are displayed to the user during installation of a WebExtension in the web browser, and during updates if new permissions are requested.

 

A dialog is displayed to the user whenever a WebExtension is installed that requires permissions, and when a WebExtension is updated that requires new permissions.

 

Firefox lists the requested permissions, e.g. access browser tabs, and users may continue with the installation or update by selecting "add" or "update", or cancel the process.

Adobe Flash plugin restrictions

Mozilla set the Adobe Flash plugin to click-to-play by default, and decided to restrict Flash to http and https pages.

Mozilla notes that the change is rolled out gradually, and may not be visible immediately to all users.

  • 5% of users two weeks after release.
  • 25% of users a month after release.
  • 100% of users six weeks after release.

Search suggestions enabled by default

firefox search suggestions

 

Search suggestions, those displayed in the Firefox address bar when a user starts to type, are now enabled for all users except those who have opted out.

Firefox users can manage search engines and suggestions by loading about:preferences#search in the browser's address bar.

 

Users who don't want or require search suggestions can turn them off by removing the checkmark from "provide search suggestions" and "show search suggestions in location bar results".

New "Performance" section in Settings

firefox performance settings

 

Firefox 55 ships with a new performance section in Settings. Firefox users may select to run the browser with the recommended performance settings, or customize the following performance-related options:

  • Toggle hardware acceleration.
  • Set a content process limits for multi-process functionality.

Page Shot screenshot functionality

firefox screenshots

 

Firefox 55 users may notice a new screenshots icon in the Firefox main toolbar. This icon is not visible to all users at release, as Mozilla wants to run an A/B test first.

 

Those Firefox users who have it in their browser already may use it to capture a region of the web browser, or a page, and save it locally or online on https://screenshots.firefox.com/.

Other Firefox 55.0 changes

  • Added Belorussian locale
  • Assign custom shortcuts to Firefox on Mac OS X via System Preferences > Keyboard > Shortcuts.
  • Firefox 55 marks the beginning of theme support. The browser.theme.update API is available which features similar capabilities as Firefox lightweight themes.
  • Geolocation API requires secure origin. Same is true for Storage API.
  • Loading of mixed content allowed on localhost.
  • Print preview feature to simplify print jobs.
  • Remote jar files are not loaded by default anymore. Mozilla disabled support for the jar: protocol back in Firefox 45, but had to re-enable it because it broke IBM iNotes functionality. Firefox 55 disables jar: again as IBM updated iNotes so that it no longer requires remote jars. Firefox users who require the functionality may switch network.jar.block-remote-files to false to restore it. (Bug 1329336)
  • Sidebar can be moved to the right.
  • Support for WebVR.
  • WebExtensions performance improvements, e.g. host matching, lazy loading APIs and more.
  • Windows Stub installer simplified, option to select installation directory or program shortcuts removed. Firefox users need to use the full installer for these options.

Developer Changes

  • about:debugging page changes. Temporary add-ons are listed at the top, a remove button is now available, and help is shown if an extension has a temporary ID.
  • Extensions may disable WebRTC.
  • Network Monitor: show hide columns, remote IP, protocol, scheme, cookies and set cookies columns, filtering of network requests by column values and other properties, and regular expressions.
  • New APIs: Collaborative Scheduling of Background Tasks API, WebVR 1.1 API, Intersection Observer API.
  • Proxy API to insert proxy configuration files into Firefox.
  • runtime.onMessageExternal API implemented to allow communication between WebExtensions add-ons.
  • Support for EME on insecure contexts deprecated.
  • webRequest API improvements, e.g. declining requests before cookies are processed.

Firefox 55.0 for Android

The following features are new or changed on Android (apart from those that were mentioned already for Firefox for the desktop):

  • Option to zoom with one hand using double tap and drag gestures.
  • Greek and Lao locales added.
  • Accessibility settings have an option to respect the system's font size when displaying web pages.

Security updates / fixes

Security changes are announced after the official release. We will update the review when Mozilla publishes them.

Firefox add-on technology is modernizing
 
Add-ons allow you to add extra features and functionality to Firefox. Anyone can create an extension and make it available for people to download.
What's happening?
 
In the past, add-ons often stopped working each time a new version of Firefox was released, because developers had to update them every six weeks to keep them compatible. Since add-ons could also modify Firefox internal code directly, it was possible for bad actors to include malicious code in an innocent-looking add-on.
To address these issues, and as part of broader efforts to modernize Firefox as a whole, we’ve been transitioning to a new framework for developing Firefox extensions. You can still personalize Firefox with add-ons the same way you do now, except they won’t break in new Firefox releases.
Note: Starting in Firefox 57, which will be released in November 2017, only add-ons built with this new technology will work in Firefox. These are indicated by the “Compatible with Firefox 57+” label on addons.mozilla.org (AMO). Add-ons built with the old technology are labeled “Legacy” on the about:addons tab.
If an add-on does not have the "Compatible with 57+" label or has the "Legacy" label, the developer may be in the process of transitioning to the new technology.
We are aware that certain add-ons will not be transitioning to the new standard; we will continue to assist developers to the fullest possible extent. As we get closer to November, we will suggest suitable replacements of add-ons not making the transition.
If you are a user of Firefox Nightly, please note that Firefox 57 reaches the Nightly channel on August 2, 2017. Legacy add-ons will be disabled, but will be enabled again if the developer releases a compatible update.
In the meantime, you can check if an add-on is planned for migration (popular add-ons only), look for alternatives, or reach out to the developer to inquire if they will migrate their add-on. You may find developer contact information on the right side of the add-on listing on AMO.
We recommend that you install add-ons with the “Compatible with Firefox 57+” label to ensure compatibility with Firefox beyond November 2017.
If you are the developer of a legacy add-on, resources are available to help you migrate to the new standard.

What people don't know is that it's a privacy risk as well, have read it before somewhere about what data it shares, sadly can't seem to find that link anymore. :(

I liked the size of the screenshot icon, though — when one gets into Customize mode there is only one icon on the Navigation Bar that stands out (hope Mozilla enhance the dimensions of all the other icons, too.)

No. Mozilla teams up with Soros to protect and spread their lies. Its very obvious if they will not tell the truth.

Effectively at the end of the article.

Putting the future of what we believe in anyone’s hands, let alone artificial intelligence, seems reckless; but a system backed by Soros and Omidyar seems like a dangerously stupid idea that can only lead to a path paved toward Orwellian censorship the likes of which even George Orwell couldn’t have imagined.
