When I read that Opera now has vertical tabs, I uninstalled my previous version and installed the new version. I soon discovered that I was unable to paste addresses into the address bar. This only happens with vertical tabs turned on, when I turn vertical tabs off I can again paste addresses into the address bar.

I am using the latest version of Opera on the latest version of Windows 11.

Edit - I can now paste into the address bar using Ctrl+V.
But that was not working earlier today.

I would also like to add that force dark mode on pages is awful. I will continue using Dark Reader.

For several months now, I've been having some Intermediate Internet issues, especially with web pages loading slowly.
On the latest update for opera One, the browser went to crap, It felt like I was on dial up again, pages were loading slowly or not loading at all. Everything I tried failed to fix the issue, so I decided to uninstall the browser, and to my surprise, my Internet is back to 100 percent again. Web pages are loading lightning fast. Why did Opera One corrupt my internet? All of these months, I've been pulling my hair out trying to fix this issue, and all it took was for me to removed that damn browser. I am so pissed off.
I am running Windows 11 fully updated to the latest version. I am also using Wi-Fi.
