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

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

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.

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://about and take note of the "profile" path. Close down Opera and delete the WidevineCDM folder in the profile folder. Then, start Opera, goto opera://components and try updating Widevine again.

You might want to make sure opera://flags/#new-component-update-mechanism is disabled too. It should be by default, but check that URL just in case.

Are you talking about the start page button that's missing on the left side of the address bar in Opera One builds?

@rnghwdbcs

In Beta, click the account icon on the address bar and log into your Opera account. Then, click the icon again and click "Sync" to goto the URL opera://settings/syncSetup. There, choose to sync everything (don't choose to create a custom passphrase). Then, close the syncSetup tab to initiate syncing. You can then monitor the syncing at the URL opera://sync-internals and even trigger updates if needed.

Then, goto https://www.sync.opera.com/, log in and confirm your data is there. Then, you can close Beta.

Then, in Opera Stable, log in to your account, goto the syncSetup page, enable syncing of everything, close the syncSetup page and wait for things to come in. Goto opera://sync-internals if needed. After a while, close Opera and open it back up if you have to.

If you need to retry syncing of Opera Stable, you can close it, and delete the "Opera Stable" folders in both "C:\Users\yourusername\AppData\Roaming\Opera Software" and "C:\Users\yourusername\AppData\Local\Opera Software". Then, try syncing again.

Or, for a way to do things without Sync, close both Opera Stable and Opera Beta. Then, in both "C:\Users\yourusername\AppData\Roaming\Opera Software" and "C:\Users\yourusername\AppData\Local\Opera Software", delete the "Opera Stable" folder and rename the "Opera Next" folder to "Opera Stable". Or, you can make a copy of "Opera Next" and rename that copy to "Opera Stable" so that Beta still has its folders if you want. It's up to you. This method usually works, but there can always be bugs caused by the profile being run with different Opera versions, so it's good to have backups if you have anything important.

Another way you can do things is via export and import. At the URL opera://password-manager/settings, you can export your passwords in one Opera and import them in another. For bookmarks, you can export your bookmarks at the URL opera://bookmarks and import them by going to the URL opera://settings/importData and choosing "Bookmarks HTML File" in the drop-down. For open tabs, before your export your bookmarks, right-click a tab, goto "save" and choose "all tabs to speed dial folder". Then, repeat for each workspace and window if needed. Then, after importing bookmarks into Opera Stable, you can goto the URL opera://bookmarks, right-click on a folder for open tabs and choose "open all".

@payard You can't set a specific shortcut for a custom site panel. However, at the URL opera://settings/keyboardShortcuts, you can set a shortcut for the "Show sidebar" command to toggle the showing of the sidebar. I like to set it to F4 as that's what old, Presto-based Opera used to use. But, you might want to use a different shortcut.

This is fixed in Opera Developer 126.0.5748.0. At the URL opera://settings/languages, you can add a language, click its 3 dots and check "Display Opera in this language" and it'll actually work.

@donq Same here. Not just you.

@fanman20 Did doing a fresh install fix the issue then?

@Kilian01 Opera had a bug a bit ago *DNA-123982( where you had to call opera-stable instead of opera to launch Opera, but it was verified fixed in 124.0.5705.30. I'm guessing that an update to a build with the fix doesn't fix the issue.

What happens if you uninstall Opera and remove any traces of it (including "opera", "opera-stable" and any aliases) (you can keep your profile in ~/.config) and then install 125 fresh? Does that sort things out? If so, that might be what users have to do to fix things if they have the issue.

No issue here in 125.0.5729.22 on Windows 11. Wonder if it's a macOS-only crash.

What version of macOS?

Is there a "Crash ID" field at the URL opera://crashes for the crash? If so, you can report it and post the bug number and crash ID here.

I tested in Linux Mint 22.1 Cinnamon (X11) with the deb packages of Opera Stable 125.0.5729.15 and Opera Developer 126.0.5742.0. I can indeed confirm that the --window-position and --window-size command-line arguments are indeed ignored by Opera and work fine in Chrome.

Indeed seems like a bug to me. Filed RNA-1806 as I don't think the issue is known (except by us here).

@RedJacK89 You can disable the "Specific keywords" flag at the URL opera://flags/#specific-keywords and restart Opera if you haven't. Don't know if that will help.

You can goto the URL opera://settings/clearBrowserData, switch to "advanced" and clear "Browsing history" and "Download history" for all time. Then, for extra good measure, goto the URL opera://about, take note of the "profile" path, close Opera and delete the "History" and History Journal files in the profile folder. This will only help though if the entry is stuck in history for some reason. If you get the entry in a test standalone installation, that's not going to help.
