Don’t understand why Web accessibility is important? Need a quick and easily-digestible guide to the top things you should be looking into in order to make your web applications screenreader ready? Try this fun, video-game-themed 5 minute video from Microsoft.
There’s a lot more to accessibility than is covered here, and it’s perhaps a little over-focussed on screenreaders, but it’s still a pretty awesome introduction.
I don’t think Microsoft using Chromium is the end of the world, but it is another step down a slippery slope. It’s one more way of bolstering the influence Google currently has on the web.
We need Google to keep pushing the web forward. But it’s critical that we have other voices, with different viewpoints, to maintain some sense of balance. Monocultures don’t benefit anyone.
This essay follows-up nicely on my concerns about Microsoft’s move from EdgeHTML to Chromium in Edge, but goes further to discuss some of the bigger problems of a homogeneous web, especially one under Google’s influence.
The younger generation of web developers are likely to hail this as good news: one fewer engine to develop for and test in, they’re all already using Chrome or something similar (and certainly not Edge) for development and debugging anyway, etc. The problem comes perhaps because they’re too young to remember the First Browser War and its aftermath. Let me summarise:
Once upon a time – let’s call it the mid-1990s – there were several web browsers: Netscape Navigator, Internet Explorer, Opera, etc. They all used different rendering engines and so development was sometimes a bit of a pain, but only if you wanted to use the latest most cutting-edge features: if you were happy with the standard, established features of the Web then your site would work anywhere, as has always been the case.
Then, everybody starting using just one browser: following some shady dealings and monopoly abuse, 90%+ of Web users started using just one web browser, Internet Explorer. By the time anybody took notice, their rivals had been economically crippled beyond any reasonable chance of recovery, but the worst had yet to come…
Developers started targeting only that one browser: instead of making websites, developers started making “Internet Explorer sites” which were only tested in that one browser or, worse yet, only worked at all in that browser, actively undermining the Web’s position as an open platform. As the grip of the monopoly grew tighter, technological innovation was centred around this single platform, leading to decade-long knock-on effects.
The Web ceased to grow new features: from the release of Internet Explorer 6 there were no significant developments in the technology of the Web for many years. The lack of competition pushed us into a period of stagnation. A decade and a half later, we’re only just (finally) finishing shaking off this unpleasant bit of our history.
History looks set to repeat itself. Substitute Chrome in place of Internet Explorer and update the references to other web browsers and the steps above could be our future history, too. Right now, we’re somewhere in or around step #2 – Chrome is the dominant browser – and we’re starting to see the beginnings of step #3: more and more “Chrome only” sites. More-alarmingly this time around, Google’s position in providing many major Web services allows them to “push” even harder for this kind of change, even just subtly: if you make the switch from Chrome to e.g. Firefox (and you absolutely should) you might find that YouTube runs slower for you because YouTube’s (Google) engineers favour Google’s web browser.
So these are the three browser engines we have: WebKit/Blink, Gecko, and EdgeHTML. We are unlikely to get any brand new bloodlines in the foreseeable future. This is it.
If we lose one of those browser engines, we lose its lineage, every permutation of that engine that would follow, and the unique takes on the Web it could allow for.
And it’s not likely to be replaced.
Imagine a planet populated only by hummingbirds, dolphins, and horses. Say all the dolphins died out. In the far, far future, hummingbirds or horses could evolve into something that could swim in the ocean like a dolphin. Indeed, ichthyosaurs in the era of dinosaurs looked much like dolphins. But that creature would be very different from a true dolphin: even ichthyosaurs never developed echolocation. We would wait a very long time (possibly forever) for a bloodline to evolve the traits we already have present in other bloodlines today. So, why is it ok to stand by or even encourage the extinction of one of these valuable, unique lineages?
We have already lost one.
We used to have four major rendering engines, but Opera halted development of its own rendering engine Presto before adopting Blink.
Three left. Spend them wisely.
As much as I don’t like having to work-around the quirks in all of the different browsers I test in, daily, it’s way preferable to a return to the dark days of the Web circa most of the first decade of this century. Please help keep browsers diverse: nobody wants to start seeing this shit –
I’ve generally been pretty defensive of Microsoft Edge, the default web browser in Windows 10. Unlike its much-mocked predecessor Internet Explorer, Edge is fast, clean, modern, and boasts good standards-compliance: all of the things that Internet Explorer infamously failed at! I was genuinely surprised to see Edge fail to gain a significant market share in its first few years: it seemed to me that everyday Windows users installed other browsers (mostly Chrome, which is causing its own problems) specifically because Internet Explorer was so terrible, and that once their default browser was replaced with something moderately-good this would no longer be the case. But that’s not what’s happened. Maybe it’s because Edge’s branding is too-remiscient of its terrible predecessor or maybe just because Windows users have grown culturally-used to the idea that the first thing they should do on a new PC is download a different browser, but whatever the reason, Edge is neglected. And for the most part, I’ve argued, that’s a shame.
But I’ve changed my tune this week after doing some research that demonstrates that a long-standing security issue of Internet Explorer is alive and well in Edge. This particular issue, billed as a “feature” by Microsoft, is deliberately absent from virtually every other web browser.
About 5 years ago, Steve Gibson observed a special feature of EV (Extended Validation) SSL certificates used on HTTPS websites: that their extra-special “green bar”/company name feature only appears if the root CA (certificate authority) is among the browser’s default trust store for EV certificate signing. That’s a pretty-cool feature! It means that if you’re on a website where you’d expect to see a “green bar”, like Three Rings, PayPal, or HSBC, then if you don’t see the green bar one day it most-likely means that your connection is being intercepted in the kind of way I described earlier this year, and everything you see or send including passwords and credit card numbers could be at risk. This could be malicious software (or nonmalicious software: some antivirus software breaks EV certificates!) or it could be your friendly local network admin’s middlebox (you trust your IT team, right?), but either way: at least you have a chance of noticing, right?
Browsers requiring that the EV certificate be signed by a one of a trusted list of CAs and not allowing that list to be manipulated (short of recompiling the browser from scratch) is a great feature that – were it properly publicised and supported by good user interface design, which it isn’t – would go a long way to protecting web users from unwanted surveillance by network administrators working for their employers, Internet service providers, and governments. Great! Except Internet Explorer went and fucked it up. As Gibson reported, not only does Internet Explorer ignore the rule of not allowing administrators to override the contents of the trusted list but Microsoft even provides a tool to help them do it!
I decided to replicate Gibson’s experiment to confirm his results with today’s browsers: I was also interested to see whether Edge had resolved this problem in Internet Explorer. My full code and configuration can be found here. As is doubtless clear from the title of this post and the screenshot above, Edge failed the test: it exhibits exactly the same troubling behaviour as Internet Explorer.
I shan’t for a moment pretend that our current certification model isn’t without it’s problems – it’s deeply flawed; more on that in a future post – but that doesn’t give anybody an excuse to get away with making it worse. When it became apparent that Internet Explorer was affected by the “feature” described above, we all collectively rolled our eyes because we didn’t expect better of everybody’s least-favourite web browser. But for Edge to inherit this deliberate-fault, despite every other browser (even those that share its certificate store) going in the opposite direction, is just insulting.
The idea is that they encourage you to give up whatever browser you’re using (assuming it’s not Internet Explorer 8), calling it names (like “old Firefox” if you’re using Firefox, “boring Safari” if you’re using Safari, “tarnished Chrome” if you’re using Chrome, and… “that browser” if you’re using Opera) and upgrade to Internet Explorer 8, and they’ll be giving out clues on their Twitter feed about some secret website that’ll only work in IE8 at which you can register and win $10,000AUS (yes, this is an Australian competition).
After looking at the site in Firefox, Safari, Chrome, and Opera, I thought I’d give it a go in Internet Explorer 8. But it didn’t work – it mis-detected my installation of IE8 as being IE7 (no, I didn’t have Compatability Mode on).
In the end, though, I just used User Agent Switcher to make my copy of Firefox pretend to be Internet Explorer 8. Then it worked. So basically, all that I’ve learned is that Firefox does a better job of everything that Internet Explorer does, including viewing websites designed to only work in Internet Explorer. Good work, Microsoft. Have a slow clap.

If you haven’t already read it, take a look at The Right To Read, a very short story written in 1997 and updated in 2002 – it’ll only take you a few minutes to read; it’s not ‘techie’ (anybody would understand it!), and it is relevant. The kind of things that are expressed in the story – while futuristic (and facist) sounding now, are being put into effect… slowly, quietly… by companies such as Sony, Phillips, Apple, and Microsoft: not to mention the manufactors of CDs and DVDs.
