Mozilla today officially released the new Firefox 78 browser. While the improvements weren’t significant, they primarily improved the user experience, such as the addition of a refresh button to the uninstaller that allowed Firefox to revert to its original configuration. Mozilla says uninstalling and reinstalling can help resolve certain issues. “Because we know that people are trying to fix the problem by reinstalling Firefox, we’ve added a refresh button to the uninstaller when a simple refresh is more likely to solve the problem,” the update log reads.
In addition, Firefox 78 has a built-in PDF reader, so starting with this version, you should see an option to open the file directly in your browser every time you download a PDF file. This is obviously welcome news for those who do not want to install another PDF client.
This Firefox update also brought significant changes to macOS users, giving up support for some older operating systems. “Firefox 78 is the last major release to support the macOS 10.9/10.10/10.11 release,” the update log reads. Users of these macOS versions will be supported through Firefox ESR 78.x in the coming year. “
