Hi @boundtobelow - which sites, which version of Opera and which version of macOS?

Hi @owilliam , it's a known issue and it'll be fixed in the next update to Opera Developer.

Does it appear if you enable if via the menu (View -> Show Toolbar in Full Screen Mode)?

Which site is it failing on? Can you show what it looks like?

Which macOS version are you on @lyopsik ? It's not a known bug.

@wingedsupernova , have you tried following the instructions and downloading it again or updating it?

Opera uses a different edition of Flash than Safari and Firefox on Mac. And even if you have installed the right edition for Opera before, it checks if the version is up to date, so updating might help in that case.

@potipharbreen Opera is not doing anything here, it's Intellicast who have decided to redirect you to Wunderground. If you want this to change, you'd have to contact Intellicast - but from what I can find on the internet it looks like a conscious decision from their common owner, The Weather Channel, to merge Intellicast and Wunderground.

@burnout426 It should work and it knows how to handle non-UIDL. M2 will only do a LIST if it has detected that UIDL is not possible, otherwise it would do a UIDL request to get message info.

@linchpinning I see! There's a difference in Opera between History (sites you've visited) and closed tabs (the state a tab was in when you closed it, by clicking the close button).

For example, you can go to www.opera.com, www.mozilla.com and www.google.com without closing or opening any tabs, so none of these will show up in closed tabs - but they'll all show up in History.

So, here are 2 options to get what you want, depending if you're interested in closed tabs or history:

1. If you want to re-open closed tabs from some time ago: click the tab menu (the weird icon top right of the Opera window) and open 'Recently Closed'. Clicking any item here will re-open the tab in the state it was closed.
2. If you want to open an item from history in a new tab: hold the 'Cmd' key when you click it.

Hi, the same happens to me when using Safari - in any case Opera's not doing anything special here
