Hey there! It sounds like you're experiencing a bit of a glitch with Firefox for iOS, where the browser is opening on the first tab instead of the last one you had open. This can be quite frustrating, especially with lots of tabs open. To help fix this, try clearing your browsing history and cache. This often helps resolve unexpected behavior like this. If that doesn't do the trick, you might want to consider uninstalling and then reinstalling the app. As for the constant cookie prompts, it might be related to website data. Go to Settings in Firefox, tap on "Clear Private Data," and select "Cookies & Site Data." This should stop those pesky prompts. Hope this helps you get back to smooth sailing with your tabs and browsing experience! If you have more questions, feel free to ask.
