You are correct in the proper extension support part. Until recently FF Android only supported a handful of selected addons made specifically for it.
uBlock Origin however has been one of those for almost a decade now.
I’m sorry you have been suffering ads all this time.
In 2023, there were over 1000 different recalls in the US which affected 34 million vehicles (bottom of the page). But just like there are around 170 000 cars that catch on fire in the US per year, which is 465 per day, they just don’t make the news because nobody cares if it’s not a new and sCaRy electric car - even though they catch fire almost a hundred times less often. Though hybrids are twice as likely than gas cars - mixing gas and batteries doesn’t seem to be a good idea.
If you want to know what cars do have recalls though, Car and Driver has collected the most relevant ones. For example, how Dodge has to recall 34000 of the 2025 RAM trucks because they have a faulty ESC.
Other picks:
Most of these you never even know about even if you own that car, because they are “soft” recalls - they get automatically fixed the next time you bring your car to service. But if you don’t own one of them, then there is almost no way you will ever hear about them. Unless it’s about a Tesla.
