Goto the URL opera://flags/#search-in-open-tabs, disable the flag, and restart Opera.

In Opera Developer (68), it has been change to a search icon. You can goto the URL opera://flags/#search-in-open-tabs, disable it and restart to get the old behavior back.

Are you using Opera 68?

Disable opera://flags/#search-in-open-tabs.

The feature was called Instant Search and Opera removed it.

The change comes from Chromium. They provided an option to disable it (for now at least). Disable chrome://flags/#enable-modern-media-controls.

Not the same, but you can hit alt + d (or ctrl + l) to focus the address field, type your search and hit alt + enter. Then, you can hit ctrl + w to close the search result page when you're done to go back to where you were.

Of course, you can just do ctrl + t, type, press enter and do ctrl + w after that instead if that's easier. Again, not the same, but...

For now, you can turn on the opera://flags/#temporary-unexpire-flags-m76 flag to get the opera://flags/#PasswordImport flag back.

The setup I did for Opera Stable (66) for libffmpeg and Widevine on Linux Mint 19.3 XFCE is this:

• Install Google Chrome and Opera.

• Create "/usr/lib/x86_64-linux-gnu/opera/lib_extra"

• Place libffmpeg.so for Chromium 79 in the "lib_extra" folder. Got it from https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases/tag/0.43.6.

• Copy "opt/google/chrome/WidevineCdm" to the "lib_extra" folder.

• Edit "/usr/lib/x86_64-linux-gnu/opera/resources/ffmpeg_preload_config.json" to be:

  []
  

• Edit "/usr/lib/x86_64-linux-gnu/opera/resources/widevine_config.json" to be:

    [
        {
           "preload": "/usr/lib/x86_64-linux-gnu/opera/lib_extra/WidevineCdm"
        }
  
    ]
  

• Uninstall Chrome and delete "/usr/lib/chromium-browser" for good measure.

In testing, unlike "lib_extra" for ffmpeg, Opera does not not search for the Widevine lib or the Widevine folder in any other place besides what's in widevine_config.json. It doesn't even search in "~/.config/opera/WidevineCdm".

(See https://forums.opera.com/post/199264 (my reply/question to @jimunderscorep) for why I edited the config files so Opera only searches for its own copies of libffmpeg and widevine.)

Goto here to download the Opera version of FVD Speed Dial. Right-click on "Add to Opera" and save the crx file to your computer. Extract the crx file to a folder (with 7-zip for example). In the folder, goto "js/bg/newtab_replace.js" and edit it. Uncomment the commented code and save your changes. Then, in manifest.json in the root of the folder, delete the update URL info (just for good measure) and save your changes.

Then, in Opera, goto the URL opera://extensions and switch on developer mode. Then, choose "load unpacked extension" and point it to the folder. The extension should then load fine.

opera://settings/searchEngines

https://translate.google.com/#auto/th/%s as the search URL should work.

Goto the URL opera://flags/#disable-accelerated-video-decode, disable the flag and restart Opera to see if it helps. If it doesn't, goto the URL opera://settings/system, disable "hardware acceleration" and restart Opera. Revert changes if they don't help.

Try playing it in full screen mode to see if that makes the video load.

@jackcabot Hmm. Maybe it's something that's already fixed that just has to reach stable.

@jackcabot In your Opera Stable, are you signed in to Google? I notice that if you're not signed in, the font on the Google search page looks a little different.

Goto the URL opera://settings/passwords and delete one of the entries. Then, goto that site, log out of it if you're not and log back in to have Opera ask you to save the login info. Tell Opera to save it and see if that one autofills. If not, maybe it doesn't have anything to do with the passwords being imported.

Did you import via csv file from Chrome via opera://settings/passwords or did you use the wizard at opera://settings/importData?

You'll probably want to compare with Chrome, Vivaldi, the new Chromium-based Microsoft Edge, Brave, and Chromium to make sure it's not just something in Chromium. Since 69, Opera uses Chromium 83 now (as opposed to 81) and the change could be in Chromium were it was just a coincidence that you install some fonts. The fonts on https://www.google.com/search?q=www.youtube.com look close to the same in Opera and Chrome on Windows 10 for me. Font looks thicker and darker for me compared to your screenshot.

Try a standalone installation of Opera Developer from https://www.opera.com/download also to see if it's any different. When you're done, you can of course delete the "Opera Developer Test" folder on your desktop just like you can delete the "Opera Test" folder.

Goto the URL opera://settings/privacy, disable "Display promotional notifications", restart Opera and see if that helps.

Also, just for good measure, you might want to reset the sidebar settings. Goto the URL opera://about and take note of the "profile" directory. Then, close down Opera and edit the "Preferences" file with JSONedit. Under root/ui/browser, right-click the "sidebar" node, delete it and save your changes. Then, when Opera starts, go ahead and click the 3 dots at the bottom of the sidebar. Then, disable all the sidebar panels you want, hide the sidebar and restart Opera. Then, see how things go. If Opera adds a new feature or if Opera updates, you might get bugged about some of the panels again though.

Do a test first. Download the Opera installer, launch it, click "options", set "install path" to a folder named "Opera Test" on your desktop, set "install for" to "standalone installation", uncheck "Import data from default browser", and install. Test in that Opera, but do not enable Opera sync, do not install any extensions, do not enable the adblocker, and enable the VPN.

Does that Opera looks correct/better.

@leocg Some of the Youtube ads are getting by uBlock Origin too, so that's probably correct.

Do you have an "N" edition of Windows?

What does https://html5test.com/ say for h.264 and aac support?
