I noticed a couple of quirky things in LibreWolf since I started using it, but I didn't connect them until today: first, without naming platforms (there were several) - when creating social media posts that included images, the image would be corrupted. Second, in G Maps, little staticy looking chunks scattered along roads. So today I pulled up the same G Maps area side by side in LibreWolf and Firefox, and realized oh, these are corrupted images of route markers in LibreWolf. And image corruption of course made me realize the same fix would probably work for my social media image post issue. Find the "Manage canvas extraction permission" icon to the left of the URL textbox, click it and click "Allow", and now that site will have access to the browser's HTML5 canvas data. This cured the corrupted social media post image uploads, and the G Maps route markers. And it's a per-site setting so it's not like you're giving away blanket access.

The issue is a side effect of LibreWolf's strict anti-tracking and all-around privacy armoring. The HTML5 canvas produces different image-rendering results on different combinations of graphics hardware, OS version, browser, and other per-user settings like desktop zoom factor or external monitor geometry. Combine all that with IP address and geolocation, and unique visitor profile "fingerprints" emerge. Analytics cartels like Alphabet and Meta coordinate these digital fingerprints across advertiser networks to target ads and even manipulate commercial social media consumers' feeds.

I'm not much concerned (today) about the data that the canvas might supply to, say, Bluesky - their monetization model is intentionally avoiding the profiling/fingerprinting practices prevalent in the commercial social media marketplace. G Maps on the other hand is probably about as invasive as infoservice can be, but it's the easiest map/nav app to use (thanks to its monopolistic position as de facto Android OS gatekeeper) and most up-to-date. Privacy-conscious alts include OrganicMaps, Maps.me, OpenStreetMaps. Apple Maps would be a contender of they cared to break into the Android platform, but as things stand the only way to use their backend is through DuckDuckGo. Needless to say that won't quite match the native navigation experience.
