    Default firefox drop-down menus vanish when scrolling onto them

    This is a problem I had in Ubuntu some years ago that just seemed to go away; sporadically I will want to select a website by positioning the cursor over the drop-down arrow to the right side of the url box- after the list is displayed it will vanish immediately when I attempt to position the cursor over it to make a selection. Minimizing then maximizing Firefox resolves it.

    A minor problem yes - but it would be nice to not have to deal with it.

    Does anyone have any suggestions ?

    Thank You.

    So you need to tell us a bit more about your setup to help. I have not seen the problem you describe and so it must be related to your setup. I am using openSUSE 11.4, 64 bit, KDE 4.6, Firefox 5.0.6 and my graphics system is nVIDIA GTX 560 and driver 280.13 loaded the hard way. I want to know the same info for your setup. The My Computer icon can help with some of this info if you are not sure.

    Thank You,

    Thanks for getting back James. My config is same as yours up to the graphics - it is an on-board ATI Radeon on a Gigabyte board. Not sure about the driver but will dig for it if need be.

    Sometimes I find solutions in these forums to be well known without details being required. Of course, if I had included them initially you wouldn't have had to ask...

    If you have AMD/ATI and you are not loading their Catalyst driver, you surely need to consider it in my opinion. I would look at the following thread for guidance. I am pointing you to the end (most recent), but reading back a little might be helpful.

    Upgrading ATI driver with atiupgrade - Page 8

    It is my opinion that the issues you are seeing are graphics driver related and it is possible loading the proprietary video driver might be helpful. Please_Try_Again seems to have a handle on this with his scripts and is a great asset to our forum. Of course, if you have money burning a hole in your pocket (as opposed to just having a hole there and losing your money) I highly recommend switching to nVIDIA where I have found the performance and driver support (from nVIDIA) to be very good. Still, you got to try Please_Try_Again's solution before you do anything else.

    I have had nVidia on a different rig that lost the mobo, and it was indeed nice. I don't have money to burn or a hole in my pocket although this mobo is a midrange, and the AMD is a lower end hex core and I have 16gb memory. It really doesn't cost all that much when you do it yourself.

    Thanks for your assistance.

    How do I discover what driver is being loaded ?

    Normally I just look into the My Computer icon display on the bottom right. You can also open up a terminal session and issue the lsmod command. Then ALL loaded modules appear, including that for video. I am not sure what name the driver you use might be going by.

    Pretty interesting display -

    radeon 986425 3
    ttm 74373 1 radeon
    drm_kms_helper 36694 1 radeon
    drm 232428 5 radeon,ttm,drm_kms_helper
    i2c_algo_bit 6342 1 radeon

    What is it telling me ?

    When displaying module information (using lsmod) such as below:

    Code:
    radeon                   986425   3 
    ttm                        74373     1    radeon
    drm_kms_helper   36694     1    radeon
    drm                       232428    5   radeon,ttm,drm_kms_helper
    i2c_algo_bit           6342       1    radeon
    The first column contains the name of the module.
    The second column refers to the memory size of the module, in bytes.
    The third column lists how many instances of the module are currently loaded. A value of zero represents an unloaded module.
    The fourth column states if the module depends upon another module to be present in order to function, and lists those other modules.
    The fifth column lists what load state the module is in: Live, Loading, or Unloading are the only possible values.
    The sixth column lists the current kernel memory offset for the loaded module. This information can be useful for debugging purposes, or for profiling tools such as oprofile.

    The module info you supplied did not include everything. The descriptions came from this link: 4.2.21. /proc/modules

    "The module info you supplied did not include everything. "

    I copied anything with the word 'radeon'.
