This is very hard for me to explain, as someone who isn't very software savvy. I use multiple Firefox profiles, open in multiple windows. Not a big deal, right? Usually when I hover on the Firefox icon on the taskbar, the 2 windows pop up and i can choose to click one or the other. It shows the window preview. It does this for all of my other applications. However, as of recent, instead of keeping both open, if i hover over one it closes the preview too fast and half of the time I'm hardly able to change windows. After a bit of digging, it seems that the tab previews are sent to the bottom of the windows, so they're hidden if I'm in fullscreen. Is there any way I can keep the tab previews on top? I don't know if this is a Firefox only issue, but I'm just now noticing it. Thanks!
