    It is interesting though that we find ourselves working around a bug we did not introduce triggered by code we do not control.

    I imagine a lot of a browser’s codebase looks like this. From what I understand, browsers expect webmasters to screw up their markup and make allowances for it.

      Wdym? Almost all programs are like this, anything that uses an external library has issues like this.

        I imagine so, but I don’t know the specifics of other software. It’s a quote from the Mastodon thread.

      I love Firefox and understand that making modern web browser is monumentally complex, but browser should not crash what ever some website does.

      That said, my Fennec is having problem with googlw images.

        Sometimes crashing would be better than trying to beat wonky code into shape: https://samy.pl/myspace/tech.html

        1. Sweet! Now we can do javascript with single quotes. However, myspace strips out the word “javascript” from ANYWHERE. To get around this, some browsers will actually interpret “java\nscript” as “javascript” (that’s java<NEWLINE>script). Example: <div id=“mycode” expr=“alert(‘hah!’)” style=“background:url(‘java script:eval(document.all.mycode.expr)’)”>

        But on principle I agree. I can’t say whether Google Images works or not on my Firefox browser, because I’m using Mojeek.

          True, sometimes it is unavoidable.

          But this looks like kernel issue, it is fixed in kernel 4.20.

        Interesting, mine isn’t. My FP4 is running 4.19, so it shouldn’t have the fix.

        I use nightly though, so perhaps the fix is already in FF?

        Even safari on iOS has the webpage crash when searching for google images…
