Diễn đàn hỗ trợ Firefox

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.

The webcam video image is being reversed or being flipped horizontally when using the latest version of Firefox. This is not happening in other browsers. I reset Firefox, but the issue still occurs. Can you advise/fix please?
