This may or may not be illegal, depending on what the “this” is you’re agreeing to. As a simple example, if it is “you agree to functional cookies by continuing to use the site”, that’s fine. If it is “you agree to us scraping your computer and selling everything we find to China”, that is most definitely not legal, nor is refusing service if you don’t agree.
Indeed, this sounds like a scummy way to sell vpn. While it is true that Facebook embeds tracking in other sites, these can be easily blocked without vpn.
Literal decades ago I bought Sennheiser headphones. They were great. They later orders of magnitude longer than anything I had before. They fit well, and were foldable, making them very compact when not used. And they were cheap too.
When they finally broke down I naturally wanted Sennheiser again, but they referred me to their new brand Epos. I bought a headset this time, not just headphones. It was a lot more expensive, and I was terribly disappointed by the ergonomics. It’s also rather big, making it unwieldy when not in use. And they broke already, though I was able to fix it - they broke just out of warranty of course.
Of course this is just one anecdote, but it really does feel like another great brand sold out and became crap.
Note that I explicitly said Chrome is worse. And "dozens" was likely an exaggeration. But yes, compared to Vivaldi, Firefox has very little customisation.
I'm going to push back against everyone saying that the algorithm knows. While not unthinkable, I believe it is much more likely that it is a coincidence, and what you're experiencing is called the frequency illusion. Simply because your sexuality has been on your mind lately, you're more likely to notice things that remind you of it - not because those things are more prevalent but simply because you, subconsciously, pay more attention to them.
That said, privacy is important and you should definitely try to maintain it - e.g. use a private browser window in a fresh browser instance to research things related to sexuality.
Ever since the first release, I've tried Firefox a few times. Each time I was left with a feeling of needing dozens of extensions to get it up to par with the browser I was using at the time (mainly Opera and now Vivaldi). The extensions I found were never customisable enough, and would often break and/or be abandoned after a while.
Don't get me wrong: Chrome, IE, Edge, and Safari are worse - each time I used them I got the urge to throw my computer out the window after just a few minutes. But Firefox is just not customisable enough to my liking, and extension are IMO not the answer.
At the very least I’d start checking for a monster chasing them off the bridge.
