Suddenly I keep getting a Extension upgrade requires additional permissions warning.
I can't see what to change to make this go away.
Please see screen shots.!

just installed 82.0.422
On the last version couldn't get flow to connect to my cell phone (Samsung) and it still doesn't (An error occurred...). There are many posts on this issue - has it been resolved?

@sgunhouse Thank You!

I see my posts from yesterday have been closed.
Exactly the same issue again. Opens full screen, no tabs, menu etc.
Last night before I switched off, I had accidentally "found" the solution - I closed a normal sized window. - restarted opera and all good. Stratup my computer today and exactly the same problem. Hit F11 - and it get minimized to the task bar. I am desperate - there if some sequence of events that I cannot find - it involves ALT+spacebar and F11 - I know someone else has had the same problem, but couldn't remember how to solve it

Found my way out somehow - combination of Alt+spacebar when minimized (I think!) and then F11

F11 minimizes Opera to the taskbar - when I hit F11 again, it goes back to full screen. If I alt+space when in fullscreen, I can minimize or exit - maximise is in bold - minimizing takes it back to the taskbar...

I don't know what I've accidentally done, but suddenly when I open opera, it runs in total full screen - no tabs, no address bar, no side panel. Have restarted - makes no difference. Esc - does nothing. Can't get to the taskbar to close it. Only way out is crtl+del end process. Please can someone help!

Running the latest Opera on my PC and Opera "full" on my cell.
When I try to install/connect to Flow on my cell, I scan the barcode but consistently get a "failed to connect" error. Any advice please?

Wow - I just find them so useful!

I was looking at Vivaldi the other day - impressed except importing Opera passwords doesn't work! - really like the ability to stack tabs, the tile tabs ability and notes that work!
Tried to search for a Chrome or Opera extension for stacking tabs and tiling tabs (nothing so far) - but came across this article
(https://www.howtogeek.com/119912/use-operas-advanced-tab-features-to-enhance-your-web-browsing-experience/)
from 2012!
What did I find?

1. Follower tabs
2. Cascade and tile tabs
3. Stack tabs
4. Built in Session Management (yes, there is V7 sessions extension)

Why on earth aren't these great features in Opera in 2020?
