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

Goto URL opera://settings/startPage. You'll see a suggestions option that you can disable (among other things).

Test this solution. Remove the Opera Safe Store password from Keychain Access login item.

Steps:

Open Keychain Access application

Choose 'login' keychain on left

Choose 'Password' group

Find 'Opera Safe Storage' entry, right click it and choose Delete.

You can goto https://addons.opera.com/en/wallpapers/?tag=animated and install one of the animated wallpapers. Then, in Opera, goto the URL opera://about and take note of the "profile" path. Then, close Opera and look in the "themes" folder in the profile folder.

You'll see the folder for the wallpaper you installed. In it, you can see how to create your own. You then just zip up your persona.ini file with the webm file and thumbnail and you 'll have your custom wallpaper.

Things you can try:

Goto the URL opera://about and take note of the "profile" path. Then, close Opera and delete the WidevineCDM folder in the profile folder.

Then, start Opera, goto the URL opera://components, click "update" for Widevine, let it update, and restart Opera.

Then, start Opera and goto https://html5test.com/ and make sure it shows "yes" for h.264 support and "yes" for aac support.

Once that's good, goto https://bitmovin.com/demos/drm, make sure it says "Using Widevine" above the video and "Widevine" for EME below the video, and "video/mp4; codecs="avc1.42c00d" for MSE below the video. And, make sure the video plays and you can hear its audio.

Then, goto the URL opera://settings/siteData, type spotify.com in the search-cookies field and choose "remove all shown".

Then, goto https://open.spotify.com/ in a new tab, log in, and try to play some music.

If you still have problems, goto the URL opera://flags/#reduce-user-agent, enable the flag, restart Opera, and try again.

If you still have problems, goto the URL opera://settings/system, disable hardware acceleration, restart Opera, and try again.

If you still have problems, goto the URL opera://extensions, disable all your extensions, and restart Opera.

If you still ahve problems, make sure you're not using Opera's VPN, and try turning off Opera's Adblocking and tracking protection.

If you still have problems, try all of the above with a standalone installation.

You can also goto the URL opera://settings/content/protectedContent, and make sure "Sites can play protected content" and "Sites can use identifiers to play protected content" are set with no sites in the custom behaviors list.

In the Opera program files directory, right-click on launcher.exe to create a new shortcut and place it on your desktop. Then, on the desktop, rename it what you want. Then, right-click on the shortcut, goto properties and then the "shortcut" tab. On that tab, modify the target to add the --user-data-dir command-line switch.

For example:

"C:\Program Files (X86)\Opera\launcher.exe" "--user-data-dir=C:\Users\yourusername\Opera2"

(I personally have a "My Program Files" folder in "C:\Users\myusername", so I'd use "C:\Users\myusername\My Program Files\Opera2" for example.)

You can create as many shortcuts as you want with each using a different profile folder.

See http://peter.sh/experiments/chromium-command-line-switches/#user-data-dir for more info.

Log into https://gemini.google.com/app in a tab.

Then, enable the "Custom user sites for browser sidebar" flag at the URL opera://flags/#sidebar-site-panel, restart Opera, click the 3 dots at the bottom of the sidebar, scroll down to Custom Site Panels and add https://gemini.google.com/app.

I finally got this to happen to me in Opera GX. I then went to the URL opera://settings/system and enabled "Use DNS-over-HTTPS instead of the system’s DNS settings". Then things starting working. I don't know if that's coincidence or not yet though.

As an alternative for now, note that you can enable the "Custom user sites for browser sidebar" flag at the URL opera://flags/#sidebar-site-panel, restart Opera, click the 3 dots at the bottom of the sidebar, scroll down to "Custom Site Panels" and add the URL for the web app you want (https://bsky.app/ for example).

You can't customize the icon for it in the sidebar and you can change its position, but it's something for now.

If you have any trouble logging in to the site in the sidebar, you can log in via a regular tab first and then reload the sidebar.

Goto the URL opera://flags/#PasswordImport, enable the import flag and restart Opera. Then, goto the URL opera://settings/passwords, click the 3 vertical dots to the right of "saved passwords" and choose to import the csv file.

For the specific format of the CSV file, export passwords to a csv file from the same opera://settings/passwords 3-dot menu in any Chromium-based browser and look at the CSV file in a text editor.

Cannot confirm on Windows 11 23H2. Tried with both regular Opera and Opera GX.

I pinned the Opera icon to the taskbar by right-clicking it and choosing "pin to taskbar". Then, I right-clicked the taskbar button, right-clicked "Opera Browser", went to "Properties", switched to the "Shortcut" tab and added a space and --private to the opera.exe command in the target field. Clicking the taskbar icon loads Opera in private mode using that existing taskbar button and doesn't create a new one.

Are you on 24H2 or a Windows 11 insider build?

You can enable logging (not crash logging) and see if the log reveals anything helpful.

@stents said in OperaGX Not Opening At All.:

117.0.5408.93

That build is for regular Opera (Opera One). Are you sure you're using Opera GX?

Upgrade to 117.0.5408.100 with "Opera_GX_117.0.5408.100_Setup_x64.exe" from https://ftp.opera.com/ftp/pub/opera_gx/117.0.5408.100/win/ to see if there's any difference.

Try making a test standalone installation of Opera Developer. Download the offline package from the developer section at https://www.opera.com/download.

If that test Opera developer installs and runs fine, close it. Then, in its install folder, there will be a profile/data folder. In it is the "Local State" file. And, in the "Default" folder there, is the "Login Data" file. Replace those 2 files with copies of the ones in "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera Developer".

Then, start that test Opera Developer and goto the URL opera://password-manager/passwords to see if your passwords are there. If so, goto the URL opera://password-manager/settings and export your passwords to a CSV file.

Once you have the CSV file, whenever you get your regular Opera Developer up and running again (by starting with a new profile and cache folder maybe), you can goto opera://password-manager/settings and import that CSV file.

As for speed dials (which are bookmarks), you can copy the "Bookmarks" and "BookmarksExtras" to the test Opera developer (choosing to overwrite the existing ones there) while that test Opera developer is closed. Then, when you start it, you should see your speed dials hopefully. You can then goto the URL opera://bookmarks and use the drop-down at the bottom left to to export your bookmarks to an HTML file. Then, in your regular Opera developer (when you get it working), you can goto the URL opera://settings/importData, choose "Bookmarks HTML file" in the drop-down and point it to the HTML file. Then, you can goto the URL opera://bookmarks and get the speed dials from the "imported" folder in the "bookmarks bar" folder, select them and move the selection to the "Speed dial" folder.

Or, another way to try things it to make a backup of "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera Developer". Then, in "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera Developer", delete everything by the "Local State" file and the "Default" folder. Then, in the "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera Developer\Default" folder, delete everything except for "Login Data", "Bookmarks" and "BookmarksExtras".

Then, Opera Developer should start mostly fresh except retain your passwords and bookmarks (speed dials too) as long as they're still in the files.

You can also try uninstalling again, deleting the Opera Developer install folder afterwards and then using the offline Opera Developer installer to reinstall.

All kinds of things you can try as I'm not sure where the issue is.

@stents said in OperaGX Not Opening At All.:

Have reinstalled GX but no success - problem persists.

Including starting with a fresh profile and cache folder?

Same issuing in a test standalone installation?

What if you hit Windows key + r to open the run dialog, type cmd and press enter to open and command prompt, type:

"%LocalAppData%\Programs\Opera GX\opera.exe" --disable-gpu

and press enter to start Opera GX (make sure there are no Opera processes running in the Windows Task Manager before you try)?

Uninstall Opera (but do not choose to delete your data when uninstalling).

Then, delete the install folder, which is the "Opera GX" folder in "C:\Users\yourusername\AppData\Local\Programs".

Then, download the Opera GX installer, launch it, click "options", adjust everything how you like and install.

@Ssouled I recently saw someone on Reddit mention that Chromium removed support for disabling efficiency mode. If that's the case, Opera probably inherited the change.

Old, Presto-based Opera had a solution for this. While you were in fullscreen mode, you could press F2, which presented you with a dialog in the middle of the screen with an address field (and autocomplete drop-down) where you could type the address you want and press enter.

Something like that might be cool for current Opera.

If you goto the URL opera://bookmarks, look for an "other speed dials" folder or something like that. Look for it in the "bookmarks bar" folder too if you can't find it in the root of your bookmarks.

If you end up finding the imported speed dials, you can select them and drag the selection to the "speed dial" folder.
