TRANSLATION ONLY _____________________ Firefox will show bug when using dual screen Hello, since the Firefox revision, in the dual-screen state, the following BUG problems will occur: 1. When Firefox takes a full screen view, the screen will be extended to another screen, or display another screen on the left and right. 2. Cannot manually zoom the browser's length and width 3. When the screen is full, the toolbar below the screen is not visible. 4. The browser is pulled to the side of the screen. Generally the browser will become half the size of the screen and display another. Side want to show the file, but after the revision of this part is broken Not sure whether the above situation is caused by the dual screen, but it is indeed the contact information that has not been found in your company before the revision. There is a message to enter Facebook but no one has responded to find it now. So hurry to contact with your company and hope to help Fix BUG or other reply, thank you! P.S. In addition, the upload file function of your company's website is broken and it is impossible to enclose images END OF TRANSLATION ______________________________________________________ Hi, yes there can be issues with Firefox and Dual Screens.
