Thread: Firefox "Security update" breaks system theme

  1. #1

    Default Firefox "Security update" breaks system theme

    Opensuse 15.3, XFCE 4.16 64bit
    I installed the Firefox "Security Update" that became available this morning. Firefox no longer honors system theme scroll bars/sliders.
    Is there any way to fix this?

    I'm also using Leap-15.3 and updated Firefox to 91.2.0-8.54.1-x86_64 this morning. I had to roll back to 78.13 because it was completely broken. It would not display any pages, not even my local home page. Menus took several seconds to appear, if ever.

    It did work in Troubleshooting Mode. I tried doing a refresh and new profile (no extensions) and it still didn't work. It only works in Troubleshooting Mode. Something is very wrong.

    I also rolled back to 78.15.0esr (64-bit). I'm fairly sure the only problems I had was with system theme being ignored in places. I tried 91.2 before, and got some advice in other forums, most of which didn't work.

    I have no issues using X11 and MATE desktop with 91.2.0 ESR.

    There have been issues when 91.2.0 ESR has been installed and using the older ESR without first closing all off the older Firefox ESR.

    If you have a problem - you might want to say what desktop and whether you are X11 or Wayland.

    It could be desktop or display issues.

    Pi4 with OpenSUSE 15.3
    Unix since 1974 (pdp-11, Interdata, AT&T, Tandy, Convergent, Sun, IBM, NCR, and HP)
    Linux since 1995 (Mandrake, Fedora, CentOS, OpenSUSE)

    I did identify the desktop... XFCE 4.16.
    I am also using the standard X11 that ships with OpenSuse 15.3.

    What do you mean by "closing all off the older Firefox ESR"?

    One can update a software package, but that does not mean that all processes using executables belonging to such a package are stopped. They can run on, still using the old executable file (that only will be deleted after all processes using it have exited.

    Thus you can update FF, still having a number of FF windows open (and those will run the "old" version). For "simple" programs that is all fine, but when programs then open other files from a package, those might now belong to the "new" version. Might be incompateble.

    I assume this is what @larryr is hinting at.

    If the newest firefox has been installed and you have the older one running and go to or update anything - the builtin migration to the newer version gets bypassed as it get used instead of the previous versions - translation - it can goof up all the mozilla files in .local .cache and .config when you start 91.2.0 ESR as well as the .mozilla file. I have not see this but someone on the Mint Linux forums said that happened to him on the new ESR.

    I tried updating firefox again, rebooted, then started with a brand new profile (firefox -p). While typing in the name for the new profile, there was a lag of 20-30 seconds between typing a key and the character showing up in the name field. top showed plenty of free memory and nothing hogging the cpu. After clicking on start firefox nothing happened for several minutes so I gave up and rolled it back again.

    My Leap 15.3 system uses lightdm -> X11 -> xfce 4.16

    I'm not sure why my previous reply did not show..
    Regarding old versions running.
    Only one version of Firefox was running at any time.
    To make sure, I renamed .mozilla and reinstalled 91.2. (I have 78.15esr installed locally in my home directory). I then logged out, restarted and logged back in. Same problem. System theme scrollbars/sliders ignored.
