Firefox 43 officially released 64-bit Firefox for Windows
Mozilla released Firefox 43 for the mobile and desktop editions. The most important change in the new version is the release of the 64-bit Windows version, but some plug-ins required for website content playback may not support the 64-bit Windows version.
Other new changes include the tracking protection feature that allows users to control the blacklist. Users can choose to block Additional tracing programs. Users can select search recommendations in the smart address bar. Users can add Tagged audio indicators to Android; new Developer Tools and bug fixes.
Although Linux and Mac OS X have obtained 64-bit versions as early as a few years ago, Windows users only need to use the 64-bit version with the default version. This is obviously unstable and there are many bugs. In fact, Mozilla had previously planned to abandon the project, and in November 2012, the team interrupted development of the 64-bit version. Almost a year ago, Mozilla announced the 64-bit Firefox restart program, which was released through development channels at the beginning of this year.
The latest 64-bit Firefox version uses new technologies to improve security and speed. However, some plug-ins cannot be supported, however, Mozilla promises to fix this issue in future updates.
