@sgunhouse Thank you.

It seems to be intermittent. I'm not sure what triggers the fault. A site's menu might work fine the first few pages then suddenly the secondary nav tabs become non clickable.

I work with a lot of websites where I have to test each one's UX so I get to see this fault frequently.

This might be a related issue. Some sites lose keyboard page scroll functionality midway through a session. Again, it is an intermittent bug. The up and down arrow keys will work great for a couple of pages within a site then suddenly cease to function in their up/down scroll capacity. Scroll bar functionality continues to work. Mouse wheel continues to work. Keyboard up/down arrow keys cease to function. Keyboard otherwise works fine.

@sgunhouse have been busy so only now able to reply. Check out this page: https://www.ampproject.org/

I am on that page now. I am not able to click secondary and tertiary items in the top menu.

Okay....

Your OS (Linux, Mac, Windows): See forum category.

Your version of Opera: See original post.

If the problem is with a page, a link to it: See original post: any page.

A description of the problem, including as much as information as possible. See original post.

Steps to (try to) reproduce the issue. See original post.

Expected behavior and actual one. See original post.

Plugins: Happens whether present or not. No plugins = same problem.

Since Opera 55 navigation menus in websites do not function correctly.

For example, find a menu with on-hover dropdown navbar items. If the pages under a main menu item tab display on-hover, Opera ignores clicks on the dropdown items. This is evident in all sites with on-hover menu dropdowns.

The problem is not present in Chrome or Firefox.

The problem happens in regular and private browsing modes.

There is a way to restore the title bar in Kubuntu so probably the same method applies to vanilla Ubuntu.

Try setting a Window Rule for Opera windows. In KDE we do this under System Settings > Window Rules and set 'No title bar and frame' to 'Force' and 'No'. That's how I got mine back.

There is a quick guide to restoring Opera the menu bar here.

@jamesisin when the title bar was taken away a menu icon was put at left of the open tabs. I seem to recall (not certain) there was once an option to enable/disable the menu button in previous versions of Opera. I can't find a flag for it now so my guess is it would be hidden in a config file that might need to be manually edited.

Without the title bar the only way to close popup windows is to right-click the task in the desktop task bar. Give us our title bar back! Had we wanted less choice we would have gone for Mac or Windows OSs.

Removing the app bar without asking first is a bit of a deal-breaker for this Linux user. I switched to Opera when Firefox started doing this kind of arrogant/inconsiderate stuff. Do I need to switch to Vivaldi or Brave as my default browser?

Same issue here. All other browsers display feeds fine. Opera displays blank page.

In case other web developers arrive here in search of an answer to localhost invalid SSL certs causing Opera to require re-login after browser restart, the solution is to visit opera://flags/#allow-insecure-localhost to enable the Allow Insecure Loclhost setting then relaunch the browser.

The OS limits Opera's access to system resources. This causes Opera to choke then crash. The problem is with Firefox, which eats all the RAM.

I do need to have multiple browsers open simultaneously. Firefox has better website (code) inspector tools than either Opera or Chrome and I use a password manager in Firefox that I can't port to Opera. I have so several hundred login credentials stored. Using more than one browser means I'm able to properly test websites and allows me to be more productive (different browsers, different tasks).

Though there is an Opera version of Autofill Forms it is a rebuilt version that uses a different code base and is functionally useless + the new version lacks import compatibility with the old version.

Would be nice if I could start Firefox then close it when not needed, which I can but it sometimes crashes the system before I get chance to close it.

The crashes happen after several hours of uptime, 24 to 48 for example, so Opera has plenty of time to store the cookies.

I'm not worried about the crashes. I'm bothered that Opera fails to fully restore my user session on restart.
