Debug steps: turn off bitwarden, my only extension. Never helps. Ctrl+Shift+Del cookies. Never helps. Sigh, open chrome. Works first time.
Is it just me or did the web up and dump firefox just when it started to get good?
:(
I asked them and they're like "yeah, it only works on chrome-based browsers". Or something to that effect. It's not like some CSS was wonky, or a bug somewhere... No, the default process of them building the SPA somehow yielded a completely non-functioning app for Firefox.
This is a change that’s been underway for years but came as a surprise when it actually shipped. I coordinated updates to ~40 packages owned by 5 different teams at my company, and had to put aside a good amount of other critical product work for about a week to ensure we didn’t encounter any customer issues.
The crux of the issue for maintainers is that Auth flows that require cookies to be sent around different origins (e.g. OAuth with form_post) will no longer work unless they update the cookies to explicitly be SameSite=none and Secure=true. Chrome led the pack on shipping the changes to browsers, but also implemented a special timeout rule that temporarily allows cookies that don’t meet the new spec to be set anyway to try to ensure auth flows don’t break. Eventually they will lift this timeout. Firefox has shipped support but has not implemented such a timeout.
For me it's usually extensions.
A truly deplorable act...
I also added about 30 seconds of latency to every page I visit, but for completely different reasons as op. Switching to Brave and blocking all cookies and JS by default made me have to manually enable it for nearly every site that I actually wanted to use.
About a week later, Chrome was reinstalled. Maybe I'll try it again once I level up my willpower.
