    Default Strange Firefox Behavior in Opensuse

    This is something I've noticed for a long time, but so far I haven't seen any automatic fixes, so I come to ask. What happens to the Firefox version of Opensuse? Some pages do not load properly and appear to be broken.

    Here an example using the forum login page. First we have the page loaded using Firefox on Linux Mint. Notice that i have tested the same page at Kubuntu, Manjaro, Fedora and Windows 10 and in all of them the results are the same below.



    And here is the same page in Opensuse's Firefox



    Another example. Some sports blog at Windows 10




    And the same page using Firefox on Opensuse:



    Just 2 examples, but this happens with others sites too. Using Chromium or Opera this error does not happen, it is a problem of the Opensuse version of Firefox only.

    Is there a way to fix this or is it a problem that only devs can solve?

    If you notice well, the only one with problems is precisely the one without Ublock.

    But, unfortunately, Ublock isn't the problem, as I've used Firefox with Ublock on Opensuse and the issues persisted. I wondered if it was going to be something with KDE, but I did a test on a TW VM running under Gnome and the problem persisted.

    Notice the shield icon next to the pad lock (left of the websites URL), this is related to Firefox content blocking.
    It's only there on your problem cases.

    https://support.mozilla.org/en-US/kb/content-blocking

    Interestingly, I have content blocking set to "strict" and yet I do not have this problem on either page, and the shield is not there.
    I also use uBlock Origin.

    Firefox 68.0.1

    I tried to disable all block contents, but no luck, all remains the same. But you post make me think of another test. I download the last Tor Browser who is based on FF 68.0 to see if the same problem happen. And, for my surprise, everything runs fine.




    Weird...

    Did you try openSUSE's FF with a virgin FF profile or a virgin user? How old is the openSUSE profile?

    The pictures above are form a fresh install on a VM, but I notice this problem since June, at first time that I installed TW on my PC.

    After poking around a bit at this...

    I couldn't find anything that's certain.
    But, I did notice that the openSUSE Firefox is several minor versions older than what I'm running on other platforms, so there could be substantial improvements to the Quantum rendering engine in later FF compared to what is in openSUSE. Here is the FF Quantum announcement

    https://www.androidpolice.com/2016/1...ngine-firefox/

    Not directly related but could be co-incidentally related and probably of interest to Users...
    I noticed a few months ago on my other systems that Firefox now has its own ad-blocking installed by default,
    But that's not implemented in openSUSE... yet.
    I suspect that simply upgrading the Firefox base version should resolve that and might fix the rendering issue as well.
    On the other hand, this could be intentional(?) since google analytics is used by the SUSE web properties to analyze traffic and would be blocked by this new feature (possibly better solution is to enable ad blocking but create an exception for SUSE web properties, and include that in the installation licensing. Or, would this violate an openSUSE FOSS policy in some unknown way? Or, should SUSE finally use something other than Google Analytics?)

    When you installed TW, did you reuse a /home filesystem used with some other distro? IOW, was the Firefox profile a virgin in June, or previously used with some Firefox other than TW's Firefox?
