Today I’ve visited TechCrunch from a posted link
https://techcrunch.com/2024/07/24/crowdstrike-offers-a-10-apology-gift-card-to-say-sorry-for-outage/
and after some reading couldn’t exit it at all tapping both my back key and the back arrow on the top.
Due to how inconvenient the arrow on top is, I suggest to make it the exit button that closes the browser and returns user to Lemmy at once, while usual back buttons keep acting like they are now.
It hijacked internal browser for me just as you described. I proposed such change because I don’t use this back arrow at all and it could’ve been handy as a force-close button.
