Komunitné fórum Firefox pre Android

I am a web developer and I noticed that my svg's have a weird box outline around them when I use the mobile version of firefox. On my desktop everything looks fine and other mobile browsers also don't have these outlines. I think it could have something to do with the animation I put on them as I haven't encountered this issue with just static svg icons for example. Here is my simplified css code for the animation: @keyframes swing {

   0% {
       rotate: var(--_from);
   }
   50% {
       rotate: var(--_to);
   }
   100% {
       rotate: var(--_from);
   }

} svg {

   --_from: -8deg;
   --_to: -18deg;
   animation: swing 8s infinite;

}

Also I was asked to choose a topic for this question and none of them realy fit. Is there maybe a different place were I should rather report this problem?

I see this "File not found" error while trying to open few PDFs using Firefox browser. For example: Income Tax return acknowledgement. I am able to open the same PDF using other Android apps like Kindle, Google Drive PDF Viewer, Files by Google etc.

Gemini says ...it's because 'Firefox for Android' does not support content:// links treating it as a security risk. Here's a screenshot for your reference:
