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.

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.

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.

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?

There's a bug (RNA-4622) about "Save as PDF" not capturing pages correctly. It's fixed internally and should be in public builds soon probably.

You can monitor the posts at https://blogs.opera.com/desktop/ for new builds, click the changelog link in each post and check the log for the bug number above to see if the fix is included. Then, you can test in that build to confirm. I can also leave a comment here if I see it in the changelog.

Seems to be working fine in Opera 135.0.5973.123 64-bit on Windows 11 for me, for what it's worth.

Same issue in a private window (ctrl + shift + n)?

With all your extensions disabled at the URL opera://extensions?

With Opera's adblocking and tracking prevention disabled at the URL opera://settings/privacyProtection?

In a test standalone installation?

See https://www.reddit.com/r/operabrowser/comments/1wbs04t/opera_browser_connector_protocol_error/.

There used to be an experimental flag for this that allowed you to control exactly what type of items showed up in the address field drop-down. The flag was removed a while ago though. Not sure why.

This is a long-standing issue. I've never been able to reproduce it myself, but many others have. Not sure why it's taking so long for Opera to fix it. Might be difficult for some reason.

@ggpbrown Yes, details about that feature are at https://www.reddit.com/r/operabrowser/wiki/opera/custom_site_panels/.

The changelog for Opera Stable 135.0.5973.123 that just came out mentions a fix for this.

It's now in Opera Stable 135.0.5973.123 that just came out.

Youtube can punish you with lagging and excessive RAM usage if it detects anything modifying the page.

Make sure Opera's adblocking and tracking prevention is completely off at the URL opera://settings/privacyProtection, make sure RGX is off at the URL opera://settings/lucidMode, make sure web modding is off at the URL opera://settings/web_modding, make sure shaders are off at the URL opera://settings/shaders, and make sure you're not using any adblock extensions at the URL opera://extensions that are getting detected by Youtube.

Then, goto the URL opera://settings/content/all, type youtube.com in the search field and click "Delete displayed data". Then, repeat for google.com. Then, goto the URL opera://settings/clearBrowserData and clear "Cached images and files" for all time. Then log back in to Google and Youtube. That should clear any adblocker detected nonsense.

As for performance on Youtube, in addition to the above, make sure graphics acceleration is enabled at the URL opera://settings/system, make sure you're not using any limiters in the GX Control sidebar panel and make sure the battery saver is disabled at the URL opera://settings/batterySaver.

Also, if needed, you can adjust the Angle flag for your GPU.

Also, sometimes issues on Youtube can be caused by GPU drivers. If you're using a gamer ready driver for example, try the stable/studio driver instead. Or, try the previous driver version.

Or, if you're happy with Edge, keep using it.

Same issue in a test standalone installation?
