Why do all Meta websites intentionally break the back button? It makes me irrationally angry every time I visit facebook or instagram for how disrespectful it is, it's like it springs a trap where I'm not allowed to leave in the browser tab I arrived in.
A random feature I didn't know for too long is long pressing the back button, which opens a menu containig the last few locations. Typically that helps with sits who hijack the back button. Works also on desktop.
What I'd love is a crowdsourced database for known back button hijackers in e.g. Firefox: If too many people report a site as being broken that way, the back button API could be made opt-in for everybody in the site settings.
Please don't complain about tangential annoyances—e.g. article or website formats, name collisions, or back-button breakage. They're too common to be interesting.
