Firefox 67.0 Changes

Control which extensions run in private browsing mode

firefox extensions run in private windows

Starting with the release of Firefox 67 Stable, all extensions that do get installed by users in the web browser won’t run in private browsing windows by default.

The installation dialog displays an option to allow a particular extension to run in private windows, and there is an option to modify the preference for each individual extension in the browser’s add-ons manager.

All you need to do is open about:addons, select Extensions from the menu, and click on any of the extensions to open its profile page. There you may need to scroll down a bit to the bottom section to allow or disallow that extension from running in private windows.

Firefox’s add-ons manager displays for each extension if it is allowed to run in private windows on the main page making it easy to keep an overview of the behavior.

All extensions installed previously retain rights to run in private windows; if you want that changed, you have to do so in the add-ons manager.

requires access

Extensions that require private window access don’t come with a switch. These state “Requires Access to Private Windows”.

Firefox Screenshots: upload functionality removed

firefox screenshots no upload

Firefox Screenshots is still a part of the browser but Mozilla decided to remove the screenshot uploading functionality of the screen capturing feature.

Mozilla announced the decision back in January 2019. Firefox Screenshots users may capture screenshots using the tool and save these to the local system.

Content Blocking: Cryptominers and Fingerprinting

Mozilla added content blocking options to Firefox 63. The update to Firefox 67 improves these by adding options to block cryptominers and fingerprinters automatically.

The options are not enabled by default. Load about:preferences#privacy in the Firefox address bar and locate the content blocking section on the page that opens.

Select Strict or Custom to enable the protection. Strict enables all protections, custom gives you options to select what you want to block. If you select custom, select Cryptominers and Fingerprinters to block these in Firefox.

Profiles per installation to avoid conflicts

firefox profiles

New Firefox installations will use a dedicated profile automatically starting with the release of Firefox 67. Firefox used existing profiles previously by default which led to two issues:

  • Profiles were shared between different Firefox installations, e.g. Nightly and Stable, which could lead to conflicts.
  • You could not run multiple Firefox installations side by side by default.

Firefox supports options to run multiple profiles side-by-side and the new release does not take these away. It makes things easier for users of the browser who install different versions of Firefox on a single device.

Other changes

    4. Space or Enter to activate a toolbar button.

  • Passwords may be saved in private browsing mode.
  • Performance improvements in various areas, e.g. automatically unload unused tabs.
  • Pin Tabs from the Page Actions menu.
  • Quick access to saved logins from Main Menu and autocomplete.
  • User Scripts WebExtensions API is coming to Firefox 68. Users may enable it as early as Firefox 66 by setting the preference extensions.webextensions.userScripts.enabled to true.
