Firefox（ファイアフォックス）

Version 74.0 （2020/03/10）

• New
  ・Your login management has improved with the ability to reverse alpha sort (Name Z-A) in Lockwise, which you can access under Logins and Passwords.
  ・Firefox now makes importing your bookmarks and history from the new Microsoft Edge browser on Windows and Mac simple.
  ・Add-ons installed by external applications can now be removed using the Add-ons Manager (about:addons). Going forward, only users can install add-ons; they cannot be installed by an application.
  ・Facebook Container prevents Facebook from tracking you around the web - Facebook logins, likes, and comments are automatically blocked on non-Facebook sites. But when we need an exception, you can now create one by adding custom sites to the Facebook Container.
  ・Firefox now provides better privacy for your web voice and video calls through support for mDNS ICE by cloaking your computer’s IP address with a random ID in certain WebRTC scenarios.

Version 73.0 （2020/02/11）

• New
  ・Firefox has offered a page zoom feature for more than a decade that allows users to set the zoom level on a per-site basis. For users who need to zoom most websites, having to adjust zoom for each new site can be an annoyance. To address this, we have implemented a new global default zoom level setting. This option is available in about:preferences under "Language and Appearance" and can be scaled up or down from 100% as needed and sets the default zoom level for all sites. Per-site zoom is still available to make adjustments to individual sites as needed.
  ・Many users with low vision rely on Windows' High Contrast Mode to make websites more readable. Traditionally, to increase the readability of text, Firefox has disabled background images when High Contrast Mode is enabled. With today’s release of Firefox 73, we introduce a “readability backplate” solution which places a block of background color between the text and background image. Now, websites in High Contrast Mode are more readable without disabling background images.
