Heads up, Firefox users. Like it or not, ads are coming to your Web browser.

Mozilla on Thursday announced it is now rolling out ads within the browser on the desktop and mobile. The ads will show up next to the thumbnails of the sites you frequently visit when you open a new tab.

Mozilla is initially launching these sponsored tiles for two companies: CVS Health and Booking.com. The ads, plans for which were first announced in February, are live now in eight languages and 25 different counties.

Mozilla will indicate which tiles are sponsored, lest you think someone has been messing around on your computer and visiting the CVS Health website a lot. If you don't want to see the ads you can turn off the tiles feature by clicking the gear icon in the top right corner of the browser to access your preferences.

The decision to roll out ads comes after Mozilla late last year hired ad tech veteran Darren Herman to explore ways of bringing sponsored content to Firefox. Mozilla spent a year prototyping and experimenting with the feature before rolling it out this week.

"There are many aspects of digital advertising that concern us: from the overall integrity of the advertising system on the Web, to the user having control over what happens to their data, and then to what happens to the data once the user has given their consent," Herman, Mozilla's vice president of content, wrote in a blog post Wednesday. "Tiles are our first iteration on starting to solve these problems."

Mozilla does not allow ad tracking, and will not collect or provide advertisers with data about you, unlike most digital ad networks. As for why it's rolling out ads, Herman said the sponsored tiles help "create a more useful, attractive and dynamic new tab page," (we'll let you be the judge of that) while helping to financially support the browser.

"These sponsorships serve several important goals simultaneously by balancing the benefits to users of improved experience, control and choice, with sustainability for Mozilla," Herman wrote.

My Experience

I'm PCMag's managing editor for consumer electronics, overseeing an experienced team of analysts covering smart home, home entertainment, wearables, fitness and health tech, and various other product categories. I have been with PCMag for more than 10 years, and in that time have written more than 6,000 articles and reviews for the site. I previously served as an analyst focused on smart home and wearable devices, and before that I was a reporter covering consumer tech news. I'm also a yoga instructor, and have been actively teaching group and private classes for nearly a decade. 

Prior to joining PCMag, I was a reporter for SC Magazine, focusing on hackers and computer security. I earned a BS in journalism from West Virginia University, and started my career writing for newspapers in New Jersey, Pennsylvania, and West Virginia.

The Technology I Use

My little Florida beach bungalow is brimming with smart home tech. I have a smart speaker or display in every room, allowing me to control other connected devices by voice. The Nest Hub on my bedside table lets me set wake-up alarms, control my smart light bulbs, and set the temperature on my smart thermostat. I use the Amazon Echo Show 8 on my kitchen counter to browse recipes, reorder protein powder, check the weather, and watch the news while I do dishes. 

Because I suffer from allergies, air purifiers are essential. My favorite model is the Dyson Purifier Cool TP07, which doubles as a fan and continuously sends indoor pollution data to its companion mobile app. 

My pitbull Bradley sheds, so a good robot vacuum is a must. I currently use a premium Ecovacs Deebot that can both vacuum and mop, empty its own dustbin, and wash its own mop cloth. 

For fitness, I like to mix up my routine with cycling, indoor rowing, running, and strength training in addition to yoga. I take classes on the Tonal 2 smart strength training machine, I row indoors on an Aviron machine, and track my beach runs with an Apple Watch while listening to music on my Apple AirPods Pro. On the weekends, I love riding e-bikes like the rugged, beach-friendly Aventon Aventure for fun and fitness.

My job involves a lot of virtual meetings, so a quality webcam, microphone, and ring light are important. I use the Jabra PanaCast 20 webcam, the Elgato Wave: 3 microphone, and a Yesker tripod ring light. 

As for my preferred phone platform, I'm an iPhone person, but I've also extensively used Android for product testing.
