What’s in the latest Firefox update? Firefox 73 adds to usability and accessibility options





Mozilla this week released Firefox 73, a minor upgrade whose most notable addition was a new default setting for page zooming.

Software engineers working on the open-source browser also patched six vulnerabilities, half of them labeled “High,” Mozilla’s second-most-serious threat rating. As usual, some of the flaws might be used by criminals.

“We presume that with enough effort some of these could have been exploited to run arbitrary code,” the firm wrote of two of the bugs.

Firefox 73 can be downloaded for Windows, macOS and Linux from Mozilla’s site. Because Firefox updates in the background, most users need only relaunch the browser to get the latest version. To manually update on Windows, pull up the menu under the three horizontal bars at the upper right, then click the help icon (the question mark within a circle). Choose “About Firefox.” (On macOS, “About Firefox” can be found under the “Firefox” menu.) The resulting page shows that the browser is either up to date or describes the refresh process.

Mozilla last upgraded the browser on Jan. 7, or five weeks ago.

From this point forward, Mozilla will refresh the browser every four weeks. Firefox 74 will end a gradual reduction to the intervals between upgrades: Mozilla announced the release speed-up in September, when it said the original six-week span would be shortened to five weeks, then to four.
