Firefox 73 Released

February 11, Mozilla released Firefox 73, an open-source web browser.  It now includes a new setting for page zooming.

Mozilla has introduced a four-week release cycle since the release of Firefox 72, and Firefox 73 is the latest release following v72, which was released in the beginning of January.

There is a new feature that helps users to view contents more easily and quickly.  To use the preexisting page-zoom feature, users had to adjust the zoom level for each new website, but now the new  zooming feature offers global default zoom level.  This can be set in about:preferences under “Language and appearance”.

The Window’s High Contrast Mode, which people with weak eyesight rely on, used to disable background images.  However, introduced with “readability backplate” solution, which places a block of background color between the text and the background images, the readability is improved.  There are other small improvements added to features like Picture-in-Picture.

There are some enhancements added especially for developers, like the new CSS logical properties “overscroll-behavior-block” and “overscroll-behavior-inline”.   There are “yearName” and “relatedYear” fields added to DateTimeFormat.prototype.formatToParts(), and “requestSubmit()” method added to HTMLFormElement interface.

On the same day, Mozilla also released the latest v68.5.0 for Android.
