    Hello list,

    Far too often, Firefox on this box will hide the tab bar, but behave as though it were still there. In other words, I have to aim the mouse
    pointer
    2cm below the thing I want to click.

    Pressing <ALT> reveals the bar but clicking in it just hides it again. I can still cycle through the tabs with the standard <CTRL><left/right>.

    Sometimes remerging Firefox fixes it, sometimes rebooting does; mostly
    I
    just have to put up with it.

    Several versions of Firefox have suffered this, and several versions of Plasma. I might submit a bug report if I could work out which component
    is
    at fault.

    Disabling my three plugins didn't help. I fixed it in the end by removing ~/.mozilla and setting mozilla up again. At least, I hope it's fixed. It's looking good so far.

    Spoke too soon. It's back again, and it's more stubborn this time. I really don't want to keep zapping my Firefox directory and setting it up all over again, especially as I don't understand what's going wrong. Any crumbs of advice or experience, anyone?

    As the Firefox dir is all text files, I think, when you blow it away and rebuild and get the correct behaviour, grab a copy. When the dodgy behaviour returns diff the copy, with the good behaviour, against the
    current dir, with the dodgy behaviour, and see what's changed. That may
    lead to an indication of what's being naughty.

    I have a recollection of doing this in the past to track down a problem.

    Just a small matter of 308 files to check. :)

    I have observed something similar in three edge use cases.

    1. When the browser is fighting against the window manager, or display environment, in the rendering of the application. I recall this being a particularly annoying problem a few years back, with Chromium on Enlightenment DE. From what I recall the problem was caused by Chromium's code taking over some window rendering functions, which conventionally was performed by the window manager. Minimising and restoring the Chromium window was a workaround to fix this problem, until Chromium improved their code.

    2. When an application window is running in a QEMU VM and the VM full desktop window itself is not maximised on the host. The mouse events are geographically misaligned with the target. After the guest desktop window is maximised the mouse becomes aligned and remains so even if the guest desktop window is resized thereafter.

    3. On a particular system I discovered Firefox tabs and scroll bar disappear, or do not respond, when running on Plasma in Wayland. Plasma in X11 plus Firefox works fine.

    I haven't found a workaround for the Firefox problem on Wayland, perhaps an update will address this.
