Google kicks out Chrome extensions after code changes bring unwanted ads

Weeks after changing its terms of service in an effort to force Chrome extension developers to keep their software “simple and single-purpose in nature”, Google has kicked out two from its Web store after violating the new rules.

According to the Wall Street Journal, the offending browser extensions – Add to Feedly and Tweet This Page – began to serve up ads after they were silently updated with adware code.

The Journal said that the new code, which injected ads onto pages where they wouldn’t usually appear, was introduced to the two extensions after the owners sold their work on to other developers who then introduced the monetization features to the software.

After the extensions started to serve up unwanted ads, their five-star ratings in the Chrome store quickly dropped to just one, with many users jumping onto message boards to air their grievances.

The move by Google over the weekend to remove the software from its store has shone a light on the practice of buying and selling extensions and their related data, and is a reminder of  how Chrome extensions are automatically updated in the background without the user knowing. In contrast, Firefox allows users of its add-ons to choose between manually checking for updates or having them installed automatically. 

‘A bad  decision’

Add To Feedly‘s developer Amit Agarwal said in a recent blog post that selling his extension was “a bad decision.”

A month after making the four-figure sale, the new owner pushed an update to the Chrome store that “didn’t bring any new features to the table nor contained any bug fixes. Instead, they incorporated advertising into the extension,” Agarwal said.

“These aren’t regular banner ads that you see on web pages, these are invisible ads that work the background and replace links on every website that you visit into affiliate links.”

He continued, “The business model of the buyer is simple – they buy popular add-ons, inject affiliate links and the bulk of users would never notice this since the Chrome browser automatically updates add-ons in the background. And there are no changelogs either.”

A member of the developer team for a Chrome extension called Honey, which has around 270,000 users, revealed on Reddit recently that several offers have also come its way in the past year.

“We’ve been approached by malware companies that have tried to buy the extension, data collection companies that have tried to buy user data, and adware companies that have tried to partner with us,” Honey’s developer said, adding, “We turned them all down.”

While the best browser extensions can help to personalize your Web experience and introduce a ton of new functionality, it’s clear that if they fall into the wrong hands somewhere down the line, they can quickly become a lost cause for many users. If the practice of new owners introducing unwanted functionality causes increasing problems, Google may consider offering users the option to turn off automatic updates, or at the least, notifying them when an extension changes hands.

Beware: many ChatGPT extensions and apps could be malware
OpenAI's ChatGPT blog post is open on a computer monitor, taken from a high angle.

ChatGPT fever has overtaken the internet, and rightly so since it's such a powerful new tool. Unfortunately, the most sought-after content is often fertile ground for hackers and scammers.

In a recent video, cybersecurity-focused YouTuber John Hammond warned that many ChatGPT extensions and apps could contain malware. It's a valid point, and we should all use caution when installing desktop browser add-ons and mobile apps.

Google Chrome’s latest update solves the browser’s biggest problem

Google Chrome is one of the best browsers around, but it's always had a big problem with memory usage. It's finally addressing the issue in a new Chrome 110 update that promises to reduce RAM usage by up to 30% and make the browser for efficient.

Chrome has a reputation for its speed, security, and feature drops, as well as a penchant for hanging on to your precious RAM like an episode of Hoarders. Granted, Google has made strides in improving Chrome's memory efficiency by hibernating tabs in the background, but it still struggles with it compared to Microsoft Edge or Mozilla Firefox.

Google may have just fixed Chrome’s most annoying problem

While Google Chrome is one of the best web browsers, over the years it has gained a reputation for being something of a resource hog, gobbling up your PC’s memory like it’s going out of style. That can be a problem if you’re running other resource-heavy tasks and don’t want things to slow down. Now, Chrome has been updated with two new features that cut down on memory usage and extend your laptop’s battery life, according to Google. The changes are set to roll out today with the latest release of Chrome on desktop (version m108).The first new feature, dubbed Memory Saver, is designed to reduce the amount of memory Chrome’s tabs use. It does this by freeing up memory from inactive tabs, and putting them to sleep so they can’t monopolize your system’s resources. When you need to access the tabs again, they will be reloaded and become active. The goal of Energy Saver, meanwhile, is fairly self-explanatory -- helping your laptop battery last longer -- but it does so in a somewhat interesting way. When your battery drops to 20%, Chrome will try to prolong your battery life by “limiting background activity and visual effects for websites with animations and videos.”Presumably, this means Chrome will limit the kind of flashy effects that have made a comeback in web design in recent years. Google says that when these new features launch, users will still be able to customize them to their liking. You can disable either Memory Saver or Energy Saver (or both), and mark certain websites as exempt in Chrome’s settings. The changes could turn out to be important. While Chrome has managed to become the dominant Windows web browser and one of the best browsers for Mac, it has been plagued by poor memory management for years. If Memory Saver and Energy Saver are able to help ameliorate that -- and make your battery last longer too -- then Google might have gone some way to fixing Chrome’s biggest problem. Both Memory Saver and Energy Saver will be launched globally over the next few weeks. The features are coming to Chrome on Windows, macOS, and ChromeOS.
