Additionally, we note Implementation of in the nightly builds of Firefox that will build the Firefox 74 release, the "browser.tabs.allowTabDetach" setting (in about:config) to prevent tabs from being detached in new windows. Randomly disconnecting a tab is one of the most annoying Firefox bugs that you can fix sought 9 years. The browser allows you to drag the tab into a new window with the mouse, but under certain circumstances, the tab is detached into a separate window and in the process of working with careless mouse movement while clicking on the tab. In order to avoid this behavior, until now it was necessary to use add-ons, such as Disable Tab Detach 2.
