Firefox and Chrome 100 could break parts of the internet, Mozilla warns

Mozilla is giving a heads up to website developers that the upcoming three-digit versions of the popular internet browsers Firefox and Chrome might cause some websites to break.

In a Mozilla blog post by Karl Dubost, Chris Peterson, Ali Beyad, the company says the error might happen when browsers parse user-agent strings containing the three-digit version numbers. 

The user-agent string contains various information about the browser software, such as the name, or, crucially – version number and supported technologies. When websites receive this information, they modify their response based on the browser version and the technologies supported. 

Preparations and mitigations

When browsers made the jump from single-digit versions, to double-digit versions, some websites could not be displayed. 

However, this time around – both Mozilla and Google are preparing for the new versions (coming in early May and late March, respectively) in advance. Last August, Mozilla started experimenting to see if version 100 would break some websites, and Google soon followed. 

In fact, both developers found a few misbehaving websites, where “unsupported browser” messages would be displayed, or broken interfaces shown.

“Without a single specification to follow, different browsers have different formats for the User-Agent string, and site-specific User-Agent parsing. It’s possible that some parsing libraries may have hard-coded assumptions or bugs that don’t take into account three-digit major version numbers,” Mozilla says. 

“Many libraries improved the parsing logic when browsers moved to two-digit version numbers, so hitting the three-digit milestone is expected to cause fewer problems.”

If the companies fail to solve the issues by the release dates, they both have contingency plans: to freeze the user-agent at 99. Furthermore, Firefox will also be able to inject CSS and other similar overrides.

Mozilla has also urged website developers to test their websites for upcoming browsers, with the detailed steps available on the Mozilla blog here

Internet Explorer might not be entirely dead just yet

Internet Explorer may soon be set for a passage to the graveyard, but developers will be able to feel like they are still using the iconic software thanks to a new launch from its successor, Microsoft Edge.

Microsoft still offers an “Internet Explorer mode” in Chromium-based Edge, but has now released a new tool to allow developers to check whether their legacy websites will still work in the more recent browser.

Internet Explorer Driver allows those organizations or developers that still require the use of Internet Explorer 11 for backward compatibility of business-critical legacy websites or apps to make sure everything is still running smoothly, for now at least.

Internet Explorer Driver

Run alongside (and maintained by) browser automation experts at the Selenium Project, Internet Explorer Driver can be a great help to developers looking to keep legacy websites or apps running that little bit longer, Microsoft says.

“With just a few changes to an existing test that runs against Internet Explorer, you can get your tests running in Internet Explorer (IE) mode in Edge,” Zoher Ghadyali, Senior Program Manager, Microsoft Edge, wrote in a blog post.

“By running your tests in IE mode, you will be able to verify that any legacy web content that runs in Internet Explorer will work as expected in IE mode in Microsoft Edge.”

Internet Explorer Driver supports C#, Python, Java, and JavaScript, and Microsoft says it will be supported until 2029, giving developers more than enough time to ensure their work is stable.

Microsoft does note that support for Internet Explorer 11 is still set to begin expiring from June 15 2022, and developers and organizations that still depend on the browser should start to transition to Microsoft Edge as soon as possible.

The company has already withdrawn Internet Explorer support for all Microsoft 365 apps, although some may still function via the browser, albeit with users seeing a severely diminished experience.

Even Google Search pulled support for Internet Explorer in October 2021, leaving the browser reliant on its own in-house Bing search, with support for Docs, Sheets, Slides and other Google Workspace apps removed in March 2021.

Microsoft Edge resurrects this classic Windows game when your internet dies

Microsoft Edge’s mini-game which can be played as a diversion when the browser can’t get online has been given a snowy twist for winter, with the traditional ‘surf game’ being changed into a skiing challenge that’s a blast of nostalgia (we’ll come back to its origins later).

If you aren’t familiar with the surf game, it’s basically Edge’s equivalent of the dinosaur game in Chrome – a mini-game for the browser which you can play when your internet is offline (or when you’re bored at any time, for that matter).

Normally, the Edge game allows you to use the keyboard (or mouse, touchscreen, or controller) to guide a surfer down the screen, avoiding obstacles, hitting jumps, and sometimes being pursued by a deadly monster – the kraken.

In the new skiing version for Edge 96, spotted by German tech site Deskmodder, the ocean is replaced by a snowy slope, and the kraken becomes a yeti (aka the abominable snowman).

Otherwise, it remains essentially the same, offering a few different modes of play (endless, time trial, and zigzag which is a slalom) and being more fleshed out than Chrome Dino (which is a pure side-scroller with the only control being space to jump).

If you want to play, simply open Edge and type in the following in the address bar:

edge://surf

Analysis: SkiFree returns after 30 years

The surf game for Edge came out in May 2020 (with build 83) and is based on Microsoft’s aged classic SkiFree game that was released way back in 1991. So in actual fact, this new winter-inspired version is a return to the original format of a skiing game.

It’s a fun distraction, for sure, and a more interesting game than Chrome Dino – plus also it’s less prone to giving us slight motion sickness, which the dinosaur game seems to do when it starts to speed up with ridiculously fast scrolling.
