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 should just be able to use --no-proxy-server without anything else.

For example:

"C:\Users\yourusername\AppData\Local\Programs\Opera\opera.exe" --no-proxy-server

Delete everything in "C:\Windows\temp" and "C:\Users\yourusername\AppData\Local\temp" again.

Uninstall Opera again, but don't choose to delete your data when asked. Then, delete the "Opera" folder in "C:\Users\yourusername\AppData\Local\Programs".

Then, open up the Windows Task Scheduler, select "Task Scheduler Library' and look in the list for any Opera autoupdate tasks and delete them. There shouldn't be any since you uninstalled Opera, but make sure because it can cause problems in some cases if after you reinstall Opera there's more than one autoupdate task for Opera.

Then, in both "C:\Users\yourusername\AppData\Roaming" and "C:\Users\yourusername\AppData\Local", right-click on the "Opera Software" folder, goto "Properties" and click the "read only" box on the General tab so that it's clear (all white) and click apply. Then, switch to the Security tab. Make sure your username is in the user list and make sure it has full control (all permissions set to allow except for "Special Permissions"). Then, click Apply. Then, do the same thing for the "Programs" folder in "C:\Users\yourusername\AppData\Local".

Then, download "Opera_122.0.5643.92_Setup_x64.exe" from https://ftp.opera.com/pub/opera/desktop/122.0.5643.92/win/ in whatever browser you want, launch it, click "options", make sure "install path" is set to "C:\Users\yourusername\AppData\Local\Programs\Opera", make sure "Install for" is set to "Current User", adjust all the other options as you like and install.

That should take care of program file issues and permission issues for your profile files.

Updating should work fine from now on unless something is interfering with Opera's updater.

Then, to avoid some quirks with updating next time, if you have "Retain tabs from previous session" set at the URL opera://settings/onStartup, whenever you're on the opera://about or opera://update page and Opera shows the "relaunch" button when the update is ready, don't click it. Instead, close that tab and close Opera yourself, wait a tad bit and then start Opera back up yourself. The reason for doing things that way is to avoid Opera relaunching with the opera://about or opera://update page loading right away. If the timing is just right, the page can mess with Opera loading the new version.

As for the sync issue, if that doesn't go away after doing all the above, you should probably start over with a fresh profile for good measure. To do that, you can rename the "Opera Stable" folder in both "C:\Users\yourusername\AppData\Roaming\Opera Software" and "C:\Users\yourusername\AppData\Local\Opera Software" to "Opera Stable old" to start over. Then, before you enabled Sync, goto https://www.sync.opera.com/ in another browser, log in and click "Reset passphrase" to wipe out all your Sync data so you don't reintroduce any issues when using Sync again.

Now, if you need to save your passwords first, you can goto the URL opera://password-manager/settings and export your passwords to a CSV file and open it in a text editor to make sure they're there. Then, in the new Opera profile, you can go back to the same URL and import the CSV file.

For bookmarks, you can use the drop-down at the bottom left of the opera://bookmarks page to export them to an HTML file. Then, in the new profile, you can goto the URL opera://settings/importData, select "Bookmarks HTML file" in the drop-down and point it to the HTML file. Then, you can goto the URL opera://bookmarks, go into the "Bookmarks Bar" folder and move the imported bookmarks to where you want them.

That's all I would back up and restore so that you don't reintroduce any problems.

You might want to check your system files and check your file system. And, check the health of your drive with CrystalDiskInfo to make sure you don't have any corruption that causes Opera to get corrupted.

You need to disable the autoupdate tasks in the Task Scheduler too if present.

Then, for extra good measure, you need to block Opera's autoupdate servers.

Also, some programs like Kaspersky can update Opera for you automatically. If you have a program like that, make sure its program updating is disabled.

If you get Opera via some package manager like Chocolatey etc., you'll want to make sure it doesn't update Opera on you.

@andrew84 If I click "pick the date" under "Filter by date" and set it to October 8th and click "Done", history that happened today on the 8th shows, but it's still shown under the "Yesterday" section and "Today" is still grayed out. So, the date picker works fine and returns the history entries it should, but those entries are just under the wrong section.

@andrew84 In 124.0.5678.0, on the opera://history page, "Today" is still grayed out and history for today is still listed under "yesterday".

@bbildman Under the "Sync Data" section on the opera://settings/syncSetup page, there's just the option for "Bookmarks", which includes speed dials (as they're bookmarks too). There's no option to sync only speed dials.

For bookmarks, these days, reusing the "Bookmarks" file on a different Opera might cause some or all of the bookmarks in it to be treated as imported or from a different device. So, look for the other Opera's speed dials at the URL opera://bookmarks. They might be in an imported folder in the "Bookmarks Bar" folder or might be in some "other speed dials" folder where you can move them to the main "Speed Dials" folder.

If you use Opera Sync to sync bookmarks, the speed dials might end up in an "other speed dials" folder too.

You can also use the drop-down at the bottom of the opera://bookmarks page to export your bookmarks to an HTML file. Then, in the new Opera, you can goto the URL opera://settings/importData, select "Bookmarks HTML file" in the drop-down and point it to the HTML file. Then, you can try finding things at the opera://bookmarks page where you can move them where you want.

The installation of extensions are tied to the user account they were installed with. Opera will remove them if the profile with the extensions is loaded by Opera with a difference user. Even if you have the same exact username on the new laptop, it's still considered a different user.

So, you have to just have to reinstall them from https://chromewebstore.google.com/ and https://addons.opera.com/.

If you enable Opera Sync on the old Opera and choose to sync extensions, extensions from addons.opera.com will sync where enabling Syncing and syncing extensions in the new Opera will cause those extensions to get automatically reinstalled. An extensions data and settings won't be synced though.

For macOS, you might have to goto the URL opera://settings/early_bird, enable Early Bird, enable "Revived GX Profiles" and restart Opera.

Then, you can create new profiles at the URL opera://settings/profiles or "Menu -> Profiles -> Add".
