Firefox’s free VPN will offer 50 gigabytes of monthly data, which is pretty generous for a browser-based VPN. A Mozilla account is required to make use of it, which isn’t a hardship (they’re free), but is a point of friction some may wish to know upfront.



For everyone who thinks this is just gonna be a way for them to somehow sell your data, I don’t think so.
Think about it like this. You can buy a VPN plan for as little as $2 a month or less depending on the provider if you have a long-term commitment (e.g. 1-2 years). That pricing includes margin.
Firefox can essentially operate at lower prices than that, because they:
I would bet this would probably cost Mozilla less than a dollar per user per month, and that’s also assuming all those users are continuing to use the VPN service over time, maxing out their data limit, but refusing to pay for anything else after.
Meanwhile, Mozilla conveniently sells their own VPN service provided through Mullvad, which they make a profit on.
If a user cares enough to continue using the VPN because they want a VPN, they’ll blow through the data limit and be more inclined than the average user to pay for Mozilla’s option. (rather than going “I guess I’ll only care about my privacy for 5 days out of the month”)
If a user doesn’t care enough to continue using the VPN because they were just trying it out, but they chose to use Firefox because it had a free VPN bundled in, which sold them on it over another browser, Mozilla just paid less than an ad would cost for a conversion.
And at the end of the day, it also just helps keep up their reputation as a browser that respects your privacy, which makes it easier to promote the browser elsewhere, in ads or otherwise.
This feels more like a marketing ploy that’s likely to just save money on ad conversions for new Firefox users, and increase Mozilla VPN conversions, rather than something they’re gonna use to super secretly siphon off your data and sell it to advertisers.
I think it would be better to compare this offer to well-known VPN providers instead of all VPN providers, since the sketchiest ones tend to have the lowest prices. The two reputable ones I can think of, Proton and Mullvad, both cost over $5/month. But cost is only half of the picture: They’ve also earned their reputation through a lot of time, effort, audits, even government raids.
Regardless, you have some good points. Let’s take for granted that Mozilla will not attempt to share or sell user data with this free service, that it’s all above-board (a fair assumption): They still have to build their reputation from zero.
Then why are they not offering at least a low cost subscription? Why are they spending money on infrastructure and support but getting no revenue in return?
Either they are okay with losing even more money, OR they plan to enshittify.
For this and many many other reasons, it’s time to switch to a privacy fork like LibreWolf or WaterFox
I already addressed this in my comment. If you want me to expand on how they most definitely can make money from something like this, Mozilla:
If this feature brings in new users, they can get revenue from any of these 3 sources, especially the sponsored listings. If this feature is just a benefit for existing users that might have already changed all their defaults and disabled sponsored content, it increases the chance of VPN conversions and donations, and increases the likelihood someone will recommend Firefox to a friend.
Or they’re trying to get and retain users, which helps them make money from existing revenue options without having to make anything worse, while also providing a beneficial feature. I’m not saying there’s no chance they’ll enshittify, but I don’t think unconditional pessimism is the right move here.
I can’t speak to Waterfox myself, but I would agree with saying LibreWolf is a good idea if you care.
I just personally haven’t bothered switching since Firefox currently works fine for me, and anything they’ve done I dislike is fairly easy to just disable in settings and never see again.
Get out of here with your level headed take. The pitchforks already have been distributed and it has been decided Mozilla will sell the data asap! /s
