Firefox Beta is the build for those who like a little bit of jeopardy, but who don’t want to risk everything by trying out Firefox Developer, the early alpha build of Firefox. Firefox Beta gives you a sneak peek at the next version of Firefox six weeks ahead of its final release, offering a relatively stable build that’s not quite ready for primetime, but still pretty solid.
Whereas Firefox Developer installs as a completely separate application alongside your existing Firefox installation, Firebox Beta will replace the stable build. Should you subsequently wish to go back to the safer version, you’ll need to manually download the stable version and install it over the top of the beta build.
Confirm which build you have by selecting About Firefox from the Firefox menu or button (it’s inside the Help menu if using the Firefox button).
Firefox 73 is now in the Beta channel. New features include:
- Added support for setting a default zoom level applicable for all web content, regardless of site. This option is available in about:preferences under "Language and Appearance" and can be scaled up or down from 100% as needed.
- Improved audio quality when playing back audio at a faster or slower speed.
- In addition to Cloudflare (which remains the default when DNS over HTTPS is enabled) and custom DNS over HTTPS provider options, users now have the option of selecting NextDNS as the Firefox DNS over HTTPS resolver via the Network Settings dialog in Preferences.
