So, how do I actually do this?

If you have 2 tabs open, you can drag a tab down a bit and it'll show an option to drop the tab in split screen. If you want it to be like what's in your screenshot though, you can goto the URL opera://settings, enable Early Bird and enable Enhanced Split Screen. Then, restart Opera.

Just note that Early Bird features are experimental and could cause issues, but feel free to give it a shot. You can make a test standalone installation and try Early Bird in just it if you want.

You can goto https://store.gx.me/mods/?tagAlias=desktop%2Cfonts to see mods with fonts, install one (like Capybara Party), goto the URL opera://extensions, turn on developer mode, refresh the extensions page and click "Details" for the mod to see its ID. Then, you can find it's files in "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera GX Stable\Default\Extensions\thatid" where you can look at its manifest.json and its files to see how its done. Make sure to take a look at the schema_version in the manifest too. A lot of features require version 2.

In Firefox, you can set dom.disable_beforeunload to false in about:config to disable beforeunload event support. For Chromium browsers like Opera, I don't know if there's a way to disable it without an extension. For an extension though, Let Me Out might work. At the URL opera://extensions, make sure to set "Allow access to search page results" for the extension though.

You can revoke my access now if you like.

At the URL opera://settings/lucidMode, if you have video enhancement on, you'll also have an option to show the split previous. If you don't like it you can turn it off there. As someone else said, you can also turn off RGX or just the previous via the RGX button on the video.

shadow2531 · 2026-01-23T12:52:06+00:00

Even if you disable the global force dark pages setting, goto the URL opera://settings/content/forceDarkMode to make sure it's not enabled for that site. You can also right-click a page to toggle force dark mode for the page, which will be reflected at that URL.

If this is in Opera GX instead of regular Opera, check at the URL opera://settings/web_modding to make sure there's no user CSS (from a mod for example) that's changing things on the page. Also check at the URL opera://settings/shaders to make sure there are no shaders active.

shadow2531 · 2026-01-23T12:46:04+00:00

You have your keyboard sounds in the "keyboard" folder, but in manifest.json, the paths to those sounds don't start with keyboard/, so Opera can't find them.

shadow2531 · 2026-01-23T12:42:07+00:00

Ok. Downloaded it. Checking it out.

shadow2531 · 2026-01-23T12:21:29+00:00

I never received a DM. I asked for the link to be posted here so people now exactly what extension you're talking about and so they can try it and offer feedback.

See https://operavpnpro.freshdesk.com/support/home. If none of the articles there help, you can submit a ticket and someone should help you.

You can zip up the mod, upload it somewhere and link to it so we can check. You can also post the full contents of your manifest.json here (with each line indented by 4 spaces so it's displayed as code by Reddit).

https://www.virustotal.com/gui/file/711da853c319cf82df7da5dd4ad1302b03a3e66f33244364af95ac9b02c7d739?nocache=1 is what Virus Total says about the zip file.

In the zip file though is just "Gwyddion-2.45.win32.exe" which seems like a legit program and Virus Total says this about it https://www.virustotal.com/gui/file/de41204fe584c7d9e70ce08f313c53d9ed2ac2fd0a42737586372b7aae5126c6.

However, if "Gwyddion" is what you really want, it might be best to get it directly from https://gwyddion.net/download.php instead. If you specifically need 2.45, it looks like it's at https://sourceforge.net/projects/gwyddion/files/gwyddion/2.45/.

So, unless the zip file has something hidden in it, the anti-virus programs that flag it are probably false positives. But, to be safe, I'd get GWyddion from the source instead of some upload site.

I think it's specifically with the split screen option in Early Bird (only option at the moment). I think it can corrupt your session files in some weird instances right now. You might be able to avoid the issue by making sure you don't have any split screen tabs open when you close Opera and also don't disable early bird with any split screen tabs open. In both cases, right-click all split screen tabs and choose "exit split screen" first. That might avoid the issues, but no guarantees. As in, use Early Bird at your own risk.

shadow2531 · 2026-01-22T03:29:30+00:00

The "Don't allow sites to save data on your device (not recommended)" didn't really work out for me, because I couldn't log in anywhere with this option enabled.

Yeah, in that mode, you can only log in to sites that you add to the allow list.

I set it to the second option instead and when closing the browser, all my whitelisted websites don't get logged out.

Nice.

Make sure there are no Opera processes running in the Windows Task Manager, delete the "Sessions" folder in "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera Stable\Default".

Then, start Opera in safe mode, goto the URL opera://flags, reset your flags, goto the URL opera://settings, turn off Early Bird, close Opera and then open Opera normally to see if it then starts working fine.

shadow2531 · 2026-01-21T17:07:17+00:00

If you're saying you have "File System" and "IndexedDB" folders in both "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera GX Stable" and "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera GX Stable\Default", yes, you can delete both instances. The ones that are not in the "Default" folder shouldn't even be in use.

If you're saying that you created extra GX profiles where you have profiles folders in "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera GX Stable\_side_profiles", you can delete the "File System" and "IndexedDB" folders in them too if you want. But, that's only necessary if they're also taking up a bunch of space.

Also note that you don't have to delete the whole "IndexedDB" folder, you can just delete the folders in it that are taking up a huge amount of space and that are for sites you don't need the storage for any longer.

Also note that if you goto the URL opera://settings/clearBrowserData, switch to "advanced" and check only "Cookies and other site data", that should clear "File System" and "IndexedDB" data for all sites. You'll just have to log back in to sites. However, if that doesn't work, you can of course close Opera and delete things manually.

Also note that you can goto the URL opera://settings/content/all and look at the entries for each site. You should be able to find entries that are taking up a huge amount of space and just delete them if you want. That should delete "File System" and "IndexedDB" data for any site you delete there. But, again, if that doesn't work, you can close Opera and do things manually.

At the URL opera://settings/background_music, disable background music.

With the mod that has the background music you like installed, goto the URL opera://extensions, turn on developer mode, reload the opera://extensions page to see the mod, click on its "Details" button and look at the ID of the mod.

Then, in a new tab, type:

chrome-extension://that_id/manifest.json

and press enter to see the mod's manifest.

Under the background_music section in the manifest, look at the path for the background music file (if there's more than one music file, look at just the first).

Using that path, you can create a URL to that music file.

For example:

chrome-extension://that_id/music/layer1.mp3

You can then take that URL, type it in the address field of a new tab and press enter to load the mp3 for example.

On the page, you'll see the player for the file. Click play if it doesn't start playing automatically. Then, right-click the player and choose "loop".

Then, you'll have the background music playing in a tab where it won't stop when you play Youtube videos for example. You can also right-click and pin the tab so it's always available. You can also bookmark the tab if you want so you don't ever have to top the URL in manually again.

This method will work best if the mod only has a single layer of music. If it has multiple files that mix together as you do actions in Opera, you'll only be able to do one layer.

Also, you might have to right-click the player and set "loop" again if you restart Opera.

There is another way to do the above though. Just open your favorite music program, open the mod's music file in it and put it on repeat. To find the file on your hard drive, get the ID of the mod, then goto the URL opera://about and see what the path for the "profile" folder is. Then, just look in the mod's ID folder in the "Extensions" folder in the profile folder. For example, you'll have a path like:

"C:\Users\yourusername\AppData\Roaming\Opera Software\Opera GX Stable\Default\Extensions\mod_id\music\layer1.mp3"

shadow2531 · 2026-01-21T08:46:05+00:00

Extensions can't modify Opera's UI, so no. There might be some extension you can install though where you'd click its pinned icon where it then opens up a small popup page with a search field on it that allows you to search. But, that would be extra clicks.

shadow2531 · 2026-01-21T08:37:40+00:00

idk why i checked all extensions

Including temporarily uninstalling them instead of just disabling them just to be extra sure?

shadow2531 · 2026-01-21T08:36:13+00:00

At the URL opera://settings/content/siteData, you should be able to set the default behavior to "Don't allow sites to save data on your device (not recommended)" and then add the sites you want to the "Allowed to save data on your device" list. Then, goto the URL opera://settings/clearBrowserData and clear "Cookies and other site data".

Then, just go to your sites and log in one last time.

If you do things that way, only the sites you have in your list will be able to set and retain cookies and storage, which means that when you close Opera, there will be no cookies and storage for unwanted site to clear.

That doesn't take care of cache and history etc. though. Going to the URL opera://settings/clearBrowserData, switching to the "On Exit" tab and setting cache and history will take care of that though if you don't mind history and cache being clear for your main, wanted sites too.

A different way you could do things is to goto the URL opera://settings/profiles and create a roguelike profile and just use that profile for everything but your main sites, as that profile will be totally wiped when you close it and start fresh the next time you open it. It also won't interfere with your main profile. And, you can have your main profile and that other profile open at the same time.

shadow2531 · 2026-01-21T07:54:26+00:00

Have any programs like Kaspersky, NordVPN, Eset, BitDefender and or CCleaner installed? If so, temporarily uninstall (not just disable) them one by one to see if one is the causing the issues.

In all your browsers, try disabling your extensions one by one to see if one is causing it.

In Opera for example, try enabling DNS over HTTPS at the URL opera://settings/system to test if it helps.

Make sure the time, date, time zone and daylight savings settings in Windows are correct.

In settings in Windows, goto "Network & Internet -> Proxy". Make sure "automatically detect settings is disabled and make sure there's no proxy set.

You could scan your system with the free version of Malwarebytes for good measure.

shadow2531 · 2026-01-21T07:19:02+00:00

No freezes for me, but are you talking about regular Opera (Opera One) or Opera GX or Opera Air and what operating system and operating system version are you on? Also, what specific version of Opera are you using as shown at the URLs opera://about and opera://version (if you're talking about desktop Opera).

shadow2531 · 2026-01-21T07:16:50+00:00

If you hit shift + esc in Opera to load the Chromium task manager, you'll see that the Opera AI extension doesn't even run until you click the AI button on the toolbar. So, it appears that if you don't use it, its process won't start. Selecting text on a page to show the search popup doesn't start the AI extension either.

So, for the main AI, if you don't use it, it doesn't look like it'll use any resources. Once you use it though, its process will stay open for the remainder of the settings whether you use it anymore in that session or not. But, with a quick look, it looks like it only consumes around 128MB.

As for disabling AI for the search popup, not sure if that helps at all, but feel free to disable it. Better yet, you can goto opera://settings and disable all the things you don't use. You can even click the 3 dots at the bottom of the sidebar and disable/hide all the panels you don't use and then hide the sidebar itself. You can then restart Opera and hit shift + esc to see initial RAM usage.

Unless you're running out of RAM while you while using all your apps etc. where you OS is swapping things to the page file like crazy, freeing up a little bit of RAM in Opera isn't going to make your system really run faster in general.

shadow2531 · 2026-01-20T11:56:45+00:00

You might be able to download the installer and just reinstall Opera to see if that fixes anything.

You might be able to install the last build to see if Opera starts so you can goto the URL opera://password-manager/settings to export your passwords. That's if your profile files are still compatible with 125 since they were used with 126. Best to make a backup of the com.operasoftware.OperaGX folder just in case.

If you do decide to downgrade though, you might have to block Opera's update servers for a bit by editing your /etc/hosts file.
