cant use the magnifying glass in firefox

when trying to use the magnifying glass in firefox to adjust the zoom it doesnt work anymore. i can open it but i cant choose anything it closes when i try. i dunno what happened as i was able to use it yesterday. i know there is the slider and the alt mouse wheel. but those ways are rather inaccurate. the magnifying glass is the best way to do it. can anyone help me get it back? or i spose it could be a bug in which case i suppose im reporting it? iunno. lol.

This is a bug that the Dev Team is aware of . For now, here are some workarounds: While hovering over the Zoom tool's icon, use arrow keys to navigate the context menu. Alternatively, use the Zoom Slider in the upper right hand corner of the tabletop. Alternatively, use the Keyboard Shortcut Alt+Mouse Wheel to zoom.
