Firefox 121

Available Firefox 121.
What's new:

This made it possible to add support for gestures on touchpads and touch screens, swipe navigation, support for different DPI settings when there are multiple monitors in the system, and also improve graphics performance. Due to limitations of the Wayland protocol with picture-in-picture windows have to either interact in a special way (usually by right-clicking on a window), or further customize the console/desktop environment (KDE / GNOME).

  • In many lines, the word “Copy”, contrary to the rules of the Russian language, is replaced with “Copy”. How said one of the volunteers supporting Russian localization, the illiterate option is more common and familiar to most users (for example, in the macOS interface Apple uses “Copy”, and Microsoft in Windows, which has many more users than macOS users, uses “Copy”). In Ukrainian and Belarusian localizations, “Copy” is also used. In addition, the language is not static, it is constantly developing and changing, and its rules adapt to the majority of native speakers.
