Here's the short answer: Fakespot is gone, and it is not coming back. Mozilla, which had owned Fakespot since 2023, announced on May 22, 2025 that it was shutting the service down. The Firefox Review Checker feature that ran on Fakespot's technology went dark first, on June 10, 2025. The browser extensions, the mobile apps, and fakespot.com itself followed on July 1, 2025. Mozilla's entire public explanation fit in one sentence: the product "didn't fit a model we could sustain."
If you landed here mid-shopping-trip and just want the protection back, I built a replacement: SureVett is a free Fakespot alternative that puts an A–F trust grade, with the reasoning shown, back on every Amazon product page. Disclosure up front, as always: I'm biased. If you want the whole field, I also wrote an honest rundown of the best Fakespot alternatives, including six tools that aren't mine.
Now the full story, because the details answer most of the follow-up questions people have.
The Fakespot timeline
2016. Saoud Khalifah founds Fakespot in New York, later joined by co-founder Rob Gross. The pitch is simple and, at the time, novel: paste an Amazon URL (or install the extension) and get a letter grade telling you how trustworthy the reviews are. The company raises about $7 million and becomes the default answer to "are these reviews fake?"
May 2023. Mozilla acquires Fakespot. The framing is optimistic: a mission-driven browser company adopting a consumer-protection tool. Mozilla says Fakespot will keep working across all major browsers.
Late 2023. Mozilla builds Fakespot's technology into Firefox as a native feature called Review Checker. This is the beginning of the strategic bet: fake review detection as a reason to use Firefox, rather than as a standalone product.
May 22, 2025. Mozilla announces it is shutting down Fakespot, in the same breath as Pocket. The explanation is that the product "didn't fit a model we could sustain," and that Mozilla is refocusing on Firefox itself.
June 10, 2025. Review Checker, the Firefox feature, is switched off. The integration that justified the acquisition outlives the announcement by less than three weeks.
July 1, 2025. The Fakespot extensions, the mobile apps, and fakespot.com all go offline. There is no data export, no handoff, no recommended successor. More than 10 million people who relied on it wake up unprotected.
Why did Mozilla shut Fakespot down?
Mozilla never elaborated much beyond the sustainability line, so anything more specific is inference. But the shape of the problem is easy to see from the outside.
Fakespot was expensive to run. Analyzing reviews at scale means continuously fetching and processing data from retailers that actively resist scraping, plus the compute cost of the analysis itself. It was also free, with no meaningful revenue attached: no subscription, no enterprise tier that ever became the story. That combination (high burn, no model) is survivable inside a growth-stage startup with patient investors. It is much harder to justify inside a nonprofit-backed organization cutting costs, which is exactly what Mozilla was doing in 2025. Pocket died in the same announcement.
The lesson I take from it, as someone building in this space: a consumer trust tool has to be cheap enough to run that it can survive on modest revenue, or it will eventually be someone's line item to cut. That's why SureVett's analysis runs locally in your browser instead of on a scraping-and-server pipeline.
The wider Mozilla context
Fakespot didn't die in isolation. The 2024 and 2025 Mozilla staff cuts and product deprecations were the backdrop. Mozilla had already restructured away from a broader services strategy, and Pocket — which had been part of Mozilla since 2017 — was shut down in the same May 22, 2025 announcement that killed Fakespot. Both were "sustainability" cuts. Both had users who cared. Both went the same way.
The pattern was Mozilla returning focus to Firefox itself and to a smaller set of high-priority bets, including AI features inside the browser. Consumer-protection tools that ran outside Firefox (Fakespot's extensions on Chrome, Edge, and Brave; the standalone iOS and Android apps) didn't fit that focus. That's the sustainability frame from the outside. From the inside, the effect was the same: two mission-aligned products that a lot of people depended on quietly went away.
What was lost
Fakespot had been running since 2016. That's nine years of accumulated data: reviewer profiles it had scored, product listings it had cached, patterns its models had learned to flag. When the service shut down, all of that vanished. There was no data export, no open-sourcing of the code or models, no hand-off to a successor project.
For an individual user, this meant your letter-grade history for products you'd checked was gone overnight, along with the extension itself. For anyone building in this space, it meant starting again from zero: there was no publicly available corpus of scored reviews to bootstrap from, no benchmark dataset, no acknowledged ground truth for "here is what a manipulated listing looks like." Every replacement tool since has had to rediscover the same patterns from scratch, which is part of why the current generation of tools is uneven in quality — some got closer to Fakespot's accuracy faster than others.
Why fake reviews got worse after Fakespot
The Fakespot shutdown happened at exactly the wrong time. Two things were already true in July 2025 that made the vacuum worse than a straight loss of a tool.
AI-generated reviews were rising fast. Anyone with a ChatGPT account could generate hundreds of unique, grammatically clean, contextually appropriate product reviews in minutes. Fakespot's models had been tuned against the earlier era of review-farm content — repetitive, awkward, template-heavy. The new wave of LLM-generated fakes was already slipping past a lot of the older detection approaches when Fakespot shut down. The ways to spot AI-generated Amazon reviews that still work today rely on subtler tells than what the 2019-era systems were built for.
Amazon didn't backfill the gap. Amazon's own automated systems continue to remove hundreds of millions of suspected fake reviews per year. The numbers are large. But Amazon's incentive to detect fake positive reviews is different from a consumer tool's. Amazon benefits from the transaction volume; the seller loses if they get caught; the consumer loses if they don't. The result is that a lot of manipulation slips through, and there's a window between "review posted" and "review removed" where the seller has already collected the sales that came from it.
No major browser stepped in. Firefox's Review Checker was the closest thing to browser-native fake review detection, and it died before Fakespot did. No other browser — Chrome, Edge, Brave, Arc, Safari — has since announced a comparable feature. If you're browsing Amazon in 2026 without a third-party extension installed, you have no automated protection at all.
Then in December 2025, FTC enforcement of the Consumer Review Rule began, with fines of up to $53,088 per fake review. That is real leverage, and it's starting to change seller behavior at the margins. But enforcement takes time, and consumer protection in the meantime lives with the individual buyer and the tools they choose to use.
Is Fakespot coming back?
No. And this one you don't have to take on faith, because every signal points the same way.
Mozilla didn't sell Fakespot to anyone. It didn't open-source the code. It didn't hand the data or the models to a successor. The domain has now been offline for more than a year, and there has been no revival announcement from Mozilla or from Fakespot's founders. If someone wanted to resurrect the brand at this point, they would effectively be rebuilding the product from scratch and attaching an old name to it.
If you see a tool claiming to be Fakespot, treat that as a red flag in itself.
Does Review Checker still work in Firefox?
No, and this is the detail people get wrong most often, including me: an earlier version of my alternatives guide said Firefox users kept Review Checker. They didn't. Mozilla shut Review Checker down on June 10, 2025, three weeks before the main Fakespot shutdown. Switching to Firefox was never an escape hatch, and there is no fake review detection built into any major browser today.
SureVett brings the A-F trust grade back to Amazon. Free, no signup, and it shows you the reasoning.
Add to Chrome — FreeWhat should former Fakespot users do now?
Three practical steps, in order of effort:
- Install a replacement extension. This is the only option that protects you automatically, on every product page, without you remembering to check. SureVett is mine: free, no account, A–F grades with the five signals behind each score shown. If you want to comparison-shop first (you should), the full alternatives rundown covers every option I could find, with the trade-offs stated plainly.
- Learn the manual tells. Tools miss things, and you won't always be on a supported site. The patterns in how to spot fake Amazon reviews take a few minutes to learn and work anywhere.
- For big purchases, add a manual LLM check. Copy 20 to 30 reviews into ChatGPT or Claude and ask for a manipulation analysis. Slow, but the most thorough single check available right now.
