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

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

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.

I finally got this to happen to me in Opera GX. I then went to the URL opera://settings/system and enabled "Use DNS-over-HTTPS instead of the system’s DNS settings". Then things starting working. I don't know if that's coincidence or not yet though.

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://flags/#PasswordImport, enable the import flag and restart Opera. Then, goto the URL opera://settings/passwords, click the 3 vertical dots to the right of "saved passwords" and choose to import the csv file.

For the specific format of the CSV file, export passwords to a csv file from the same opera://settings/passwords 3-dot menu in any Chromium-based browser and look at the CSV file in a text editor.

@DavidCarter Start Vivaldi back up really quick and set "save browsing history" to "forever". That will recreate everything. Then, close Vivaldi and copy Opera's history file back over again.

@DavidCarter Try it this way. In Vivaldi, goto the URL vivaldi://settings/privacy, set "Save browsing history" to "Forever" and close Vivaldi.

Then, copy the "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera Stable\Default\History" file to "C:\Users\yourusername\AppData\Local\Vivaldi\User Data\Default" while choosing to overwrite Vivaldi's existing one there.

Then, start Vivaldi and goto the URL vivaldi://history. If you're lucky, you'll see Opera's history. And, if you're really lucky, you'll see Opera's history that's older than 3 months. No guarantees.

Modifying the Vivaldi "Preferences" file like I said in the linked post you mentioned shouldn't be needed. Not sure why I said that in the linked post. Don't remember. However, here's a screenshot of how it should look in Vivaldi's Preferences file in JSONEdit:

@DavidCarter said in [Duplicated]Opera deletes my browsing history more than 90 days old?:

My 2 Opera Stable folders are a combined size of 1.575 GB so that entire history must be in there.

In SQLiteStudio, you can goto "Database -> Add a database", point it to the "History" file in the roaming "Opera Stable" folder (set the file-type filter in the open dialog to "all files"), right-click the History database in the left-hand pane, and choose "Connect to database". Then, you can double-left-click on the "urls" tab in the left-hand pane and switch to the "data" tab in the right-hand pane. You can then do the same with the "visited_links" table.

That will allow you to see if entries older than 3 months are in there. But, whether they are or not, we volunteers cannot do anything about it and have nothing to do with the behavior of Chromium and Opera's choice to not work around the issue like Vivaldi does.

Not sure why the installer takes so long for you to open/display when you launch it. I don't think Chrome is delaying it in any way. Anti-virus might though in some rare cases.

You might want to delete everything in "C:\Windows\temp" and "C:\Users\yourusername\AppData\Local\temp" to see if the Opera installer launches right away the next time you use one.

Did you use the simple net installer (that's not very big in file size that fetches the install files from Opera's servers when you try to install) or the offline installer (that's a big file that already includes all the install files)?

@jaxx0rr said in Opera installer takes 5 minutes to load on a fresh Win 11 / SSD / 32gb ram:

the option is in the "On Startup" section called..
"Run when my computer starts"

The option is also in the installer. When a user launches the installer, they can click "options" to adjust the install options and uncheck "Run when my computer starts" if it's checked.

https://chromewebstore.google.com/detail/history-trends-unlimited/pnmchffiealhkdloeffcdnbgdnedheme might help. It copies history entries to a local database (separate from the History) file to retain history forever.

See https://issues.chromium.org/issues/41182726 for a complaint/feature request.

See https://issues.chromium.org/issues/40358997#comment24 for a partial explanation of why Chromium has the limit.

Also see this Brave discussion at https://community.brave.com/t/longer-browsing-history-than-the-3-month-default/501595/1.

Vivaldi has an option at the URL vivaldi://settings/privacy/ to save history despite it being based on Chromium. But, I'm not sure how they do it and not sure if there any caveats.

@trustissues said in How to stop PDF automatic downloads (again)...:

I'm part of a few woodworking groups and I occasionally view PDFs with plans,

Link to group and post that has PDF?

@icebrg77 said in Can I export or print my Opera GX history file?:

I have it pulled up in an SQLITE viewer but cannot export or print.

https://sqlitestudio.pl/ can do that. After you add the History file as a database and connect to the database, you can right-click on the urls table and export the data in various formats. You can do that with the "visited_links" table too. You can also print the data.

When Chromium finally removes the MV2 API code, if Opera wants to keep supporting MV2, Opera will have to patch it back in with each new build of Opera. This might not be maintainable as Chromium code continues to change. So, I wouldn't be surprised if MV2 support disappears eventually.

What does Chrome at when you use a custom DNS provider at the URL chrome://settings/security and turn DNS over HTTPS off and on? Does it retain the custom entry? If not, it might be an issue in Chromium that needs to be fixed/supported so all Chromium-based browsers retain the setting.
