The recent update 149.0 introduced a new look to the error pages. Every single time the requested URL does not exist, a page's servers are down, or your internet is turned off, it shows an image of a fox biting a power plug. The image is no-connection.svg located in omni.ja (chrome://global/skin/illustrations/no-connection.svg). Such a location rooted in the files cannot be zapped by uBlock Origin. I tried to replace the image inside omni.ja using 7-zip, but it can't do so because the Mozilla Firefox folder is Read-Only, and keeps turning so despite me unchecking the Read-Only checkbox in properties. I tried looking for a variable in about:config, toggled svg.disabled from false to true, it didn't help. My goal is so that only text appears on error pages, and no images, like it was in the previous update. Ideally I would like to have the option to completely eliminate corporate artwork from my copy of Firefox. Help would be very much appreciated, because Firefox is my favourite browser by far
