No, you swipe up on the tabs to dismiss them pre-iOS 15. Just as you would close out apps.The content blocker stuff works the same as before. In iOS 14, you tap the ‘AA’ button and then ‘Turn off Content Blockers’. As far as I know, holding the reload button to reload without content blockers was never a thing in iOS 14, and I doubt it changed in iOS 14.7. (Just tried it on my iOS 14.6 devices and nothing happens when I hold the reload button.)
Also, the ‘Turn off Content Blockers’ option only applies to that page. It’ll turn back on if you reload normally, tap a link, or go to another site. This is exactly the same in iOS 14 as well.
Nothing changed here either. You swipe left to close tabs in iOS 14 too.
Scrolling down thru all of the options and selecting “Turn off content blockers” on iOS 15 turns off content blockers all together. Not just for that site and session.
Tapping and holding the reload icon in the Address Bar pre-iOS 15 gives you the option to reload the page without content blockers, and it stays that way just for that page/session. This option does not exist on iOS 15. Nearly everything you replied to me with isn’t true.
