Is there something particular going on or that has occurred to make you say this? Wondering what I’m missing.
Not one thing in particular but a general trend driven by several factors. Things recently have, are, and will continue to heat up.
For one, past few months a few significant supply-chain attacks have been hitting popular developer tooling and libraries used for web development. As devs get compromised, this will "trickle down" to users.
For two, as stakes are rising, devs are burning out and the economy is shifting, crap like this is just considered "Monday" now. Already been common with browser addons for a while now.
As for browser themselves, take a closer look at release notes and changelogs (for forks, go to upstream). Note the number and severity of addressed issues and update frequency.
Adoption and evolution of LLMs also tie into this in multiple ways. Others have written in length about this. If there is one thing doomers and hypers agree on, it's this.
Oh, and be careful with archive links.
