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?

Long shot, but at the URL opera://settings/content, scroll down to the bottom of the page, disable "Automatically remove permissions from unused sites" and restart Opera. Then, enable notifications for WhatsApp again if they're removed and restart Opera again. Then, see if things stick.

It's a known issue. It's already fixed in Opera Developer so far.

@korol78 There's also a complaint about that at https://www.reddit.com/r/operabrowser/comments/1w3d9q2/how_to_disable_the_bubble_saying_chatgptcom_its/, for what it's worth.

@UltraVio1et See the pull requests at https://github.com/flathub/com.opera.Opera/pulls if you haven't.

There's a command at https://github.com/flathub/com.opera.Opera/pull/285#issuecomment-5512723300 that you can use to install the latest if you like for now.

I tried reporting this issue to Pluto, but they said that Opera is currently not supported and wouldn't listen and didn't care.

The good news is that an awesome Opera dev made a browser.js fix to work around Pluto blocking Opera. It's in the new 135.0.5973.76 build that just came out.

For now, you can disable the "History Redesign" flag at the URL opera://flags/#history-redesign to get the old opera://history page back. Just note that Opera will eventually remove the flag so that you can't revert.

You can test if it happens in a test standalone installation.

You can adjust the Angle flag to see if one of the options for the flag avoids the flickering while keeping hardware acceleration enabled for most things at the URL opera://gpu.

You can disable graphics acceleration at the URL opera://settings/system to test if it helps.

If you're using a game ready driver for your GPU, try using the stable/studio driver instead.

You can make a test standalone installation of the last build of Opera to see if it works fine or if Opera updating was just a coincidence.

You can disable lucid mode at the URL opera://settings/lucidMode to see if that helps.

You can disable Early Bird at the URL opera//settings/early_bird to see if it helps.

You can test if it only happens with certain themes.

An alternative for now:

Set everything up how you like it. Then, goto the URL opera://configure/mods, hover over the center Opera icon on the page and click the "Set image" icon and pick an image. Then, hover over the new image that's now in the center of the page and click the "save preset" button.

You'll then see your new preset in the preset section on the page (along with the 2 default ones). Then, if you ever need to switch back, just click that preset. You can also switch presets in the Easy Setup menu.

I can't seem to reproduce it in Opera GX on Windows 11. Does it happen in a test standalone installation too?

As a workaround for now, you can download my "Mask_as_Chrome_on_Pluto_tv.zip" from here, extract it, goto the URL opera://extensions, turn on developer mode, click "load unpacked" and point it to the extracted folder where manifest.json is at. Then, at the URL opera://extensions, enable "Allow access to search page results" for the extension. And, if you want to use it in a private window, enable incognito mode for the extension.
