We also need to talk about Source Order vs. Tab Order—they’re more different than you’d expect 👀. Source Order is the sequence of nxodes inside their parent in the DOM. Tab Order is the sequence of focusable nodes navigated using the Tab key.

One of the downsides of tools like this is that your URL needs to be available online so if there's an issue, your iteration loop is quite long.

Take your Kindle and visit https://html5test.com/ and that should give you a good idea. Spoiler: it scores pretty low but supports JavaScript, which is surprising. PS: You could have gotten this answered more quickly by Googling. - Source: Hacker News / 8 months ago
I just don't know what else I can do. I compared Chromium and Firefox in html5test.com, got same result. All browsers says they doesn't support H.265. I turned off HW acceleration, nothing changes. I installed ffmpeg-libs and other codecs from Fedora wiki. Nothing changes. Videos are same vp9 in browsers. I spent all day googling but nothing helpful. Source: almost 2 years ago
What does https://html5test.com/ say for h.264, VP8, VP9 and Theora support? What does it say for aac, Opus, Vorbis and mp3 support? Source: almost 2 years ago
You can use this website also https://html5test.com is really helpful with more datails. Source: almost 2 years ago
If I go on html5test.com, no matter which browser I use, H265 support is not enabled and I couldn't find any article online that explains why -- what am I missing here? Source: almost 2 years ago
