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?

You can create a folder named "test", put:

manifest.json:

{
  "mod" : {
    "schema_version" : 2,
    "payload" : {
      "app_icon" : [ {
            "id" : "app_icon_01",
            "name" : "Test",
            "path" : "app_icon1.png"
        }
      ]
    }
  },
  "manifest_version" : 3,
  "name" : "Test",
  "icons" : {
    "512" : "icon_512.png"
  },
  "version" : "1.2.1"
}

in it, put icon_512.png and app_icon_01.png (290px x 290px) in it, goto the URL opera://extensions, turn on developer mode, click "Load unpacked" and point it to the test folder to load the extension.

Then, you can goto the URL opera://configure/mods/interface/app_icon, set the mod's icon and restart Opera.

Then, Opera's pinned taskbar icon should be that custom icon.

You can definitely create your own extension that uses a custom app icon and it will work no problem when you "Load unpacked" it in developer mode at the URL opera://extensions.

As for uploading said extension to https://store.gx.me/mods, I'm not sure if there are any restrictions for what studios are allowed to do app icons there or if there are any restrictions for what mods can be tagged with the app-icon tag. For example, I think the mods-2-0 tag is restricted to Opera-provided mods but there are still lots of mod 2.0 mods that aren't tagged as such.

You can keep installing mods form other studios and check at the URL opera://configure/mods/interface/app_icon to see if they an app icon. At https://store.gx.me/mods/, maybe sort by last modified so you get newer extensions. You'll still have to skip Opera studio mods though.

Same issue in a test standalone installation?

Tested in Opera Developer 121.0.5600.0 (installer for it is broken though unless you do a standalone installation) based on Chromium 137 and discarding works. Might have to work to GX is based on 137.

What specific version of Windows are you on?

@mariuszlol23 It'd be under "Settings -> Accounts -> Family" in Windows if you want to double check.

Besides that, you can uninstall Opera (do not choose to delete your data when uninstalling), but this time, delete the install folder afterwards. Default location is "C:\Users\yourusername\AppData\Local\Programs\Opera".

Then, delete everything in "C:\Windows\temp" and "C:\Users\yourusername\AppData\Local\temp".

Then download Opera's installer, launch it, click "options", review and adjust everything how you want.

Besides that, you can rename the "Opera Stable" folders in "C:\Users\yourusername\AppData\Roaming\Opera Software" and "C:\Users\yourusername\AppData\Local\Opera Software" to "Opera Stable old" to see if starting with fresh data fixes it.

Besides that, I'd look into security software like Bitdefender, Kasperksy and Eset. They might be interfering. You might have to temporarily uninstall them and not just disable them to test if they're really interfering.

You should probably make sure a test standalone installation of Opera works fine. If not, then there's definitely something on your system interfering with Opera.

@ALG4ZIII No. haven’t tested in Opera Developer with the newest Chromium137 build to see if it’s fixed there or not yet.

@XOXOGossipBoy I have a feeling it’s not Defender, but it’s worth trying that just to rule it out.

There's a good chance it's antivirus software that's causing it. Bitdefender, Kaspersky and Eset for example. You might have to temporarily uninstall them to and not just disable them to test if they're interfering with Opera. You might want to reinstall Opera after uninstalling them too.

Standalone installation option works at least (to a fresh folder on my desktop). The current user and all users options fail.
