Honey

In our opinion, Honey is one of the best shopping browser extensions and the one we’d most recommend you install. It automatically applies coupons before checkout from its database, all but ensuring you’re getting the best price. The best part about it is it’s all automatic. How easy is that?

Web of Trust

Web of Trust (WOT) - Browse & Search The Web Safely

A little nervous about shopping online? Don’t want to be snookered by a site with a deal that looks too good to be true? This browser extension checks websites for telltale signs of potentially suspicious activity, using an easy-to-understand green/yellow/red color system to let you know which sites are trustworthy and which ones you should probably steer clear of.

Fakespot

Sometimes reviews on Amazon look too good to be true. And in some cases, that’s precisely what they are: reviews either written by employees or others paid to post a glowing (but faked) review of a product. This extension spots those fake reviews and highlights them — and it’s compatible with several retailers, including Amazon, Best Buy, Walmart, and Sephora. It even works on Tripadvisor and Yelp for good measure.

Amazon Assistant

If you’re a big Amazon shopper, you’d be foolish not to install this extension. Amazon Assistant sits in the background and monitors when you’re on a competing website. If Amazon has the same product available, a banner appears at the top of your screen showing Amazon’s price. If it’s cheaper, you can click through and buy it from Amazon instead.

Pricescout

If you like Honey, you might like Pricescout even better. While Pricescout performs the same function and finds you coupons and automatically adds them to your cart, it also comparison shops across websites. This allows you to check for better prices elsewhere quickly and easily without having to visit each site.

Rakuten Cash Back Button

Get Cash Back with the Rakuten Cash Back Browser Extension!

You might be familiar with Rakuten’s online storefront, but the company bought cashback company Ebates not too long ago to expand its service. The result is the Rakuten Cash Back Button, which not only automatically applies coupons, but also offers cash back from nearly 2,500 retailers to boot. All you need to do is shop like usual: the button appears when cashback is available. Click it to cash in!

InvisibleHand

After all this shopping, do you feel like you need to get away? While InvisibleHand does offer some shopping deals, it works exceptionally well for flights, hotels, and rental cars. Vacations can get expensive, so don’t plan your next one without this helpful browser extension.

ChatGPT’s hiking advice left two hikers stranded on a mountain in Poland
The chatbot directed the pair onto a climbing route neither had the skills to finish, and it's not the first time AI has sent travelers somewhere they shouldn't have gone.
Bag, Clothing, Coat

A shortcut recommended by ChatGPT left two hikers stuck on a mountain face in Poland this month, and they needed a helicopter to get back down. It's the latest case of an AI chatbot steering travelers toward routes it has no real way to evaluate.

Firefox is doubling its update pace, and that’s good news for your security
Mozilla Firefox

Mozilla is about to speed up one of the most important parts of using Firefox: security updates. If you're used to seeing a new Firefox update land about once a month, that's about to change. Beginning in September, Mozilla plans to switch to a two-week release schedule for Firefox on desktop and Android, meaning users should start getting updates twice as often. That might sound like more frequent downloads, but it's really about closing security gaps sooner.

Why waiting a month for security fixes no longer cuts it

Anthropic just published research confirming that its chatbot's personality shifts depending on which model you pick and which language you type in, and the pattern is consistent enough that it's worth knowing before you ask your next question.
