Mozilla officially released a new version of its browser, Firefox 78, today. Although the improvement is not great, it mainly improves the user experience. For example, the unloader adds a refresh button, which can restore the initial configuration of Firefox. . "Because we know people are trying to fix the problem by re installing Firefox, we have added a refresh button to the uninstall program when a simple refresh is more likely to solve the problem," the update log said.
In addition, Firefox 78 has a built-in PDF reader, so from this version, whenever you download a PDF document, you should see an option to open the file directly in the browser. For those who don't want to install another PDF client, this is obviously a welcome message.
This update also brings significant changes to Mac OS users, abandoning support for some older operating systems. "Firefox 78 is the last major version to support MacOS 10.9/10.10/10.11," the update log said. Users of these MacOS versions will be supported through Firefox ESR 78. X in the next year. "
