Fixed in 118.0.5461.60.

It works fine for me now.

I can see nothing about it in changelog, but for me issue disappears of 120.0.5543.128.

I've got the same problem! I noticed this because I've blocked notifications and only grant permission manually to certain websites. But after a while - a few hours or a few restarts - those websites suddenly no longer have permission... It's so annoying! Camera and microphone permissions behave in exactly the same way, but I use those much less often, so it doesn't bother me as much. However, I can confirm that this problem does exist.

"Automatically remove permissions from unused sites" is disabled.
I don't clear "site settings" (on exit) and Opera don't allow me to enable it coz I have sync on.
AppData Roaming and Local:

• "click the read only box to clear it": didn't help,
• "Security" tab: it's everything fine there.
  "Reset passphrase": I done it, additionally I turned off "Settings" sync this time: didn't help.
  "System -> Notifications" it's everything fine there... Notifications works as long as Opera doesn't remove them.
  CCleaner etc - I don't use apps like that.

Standalone installation / completely fresh profile - I might test this out if I find the time, but like @MichaIng wrote, I'm afraid the problem will return and my efforts will go to waste

I use installed and synced instance but I se here are users with portable and logged out instalation and have the same problem.
And as I wrote previously - this also applies to camera and microphone permissions, but I use notifications every day and I notice their absence immediately. So I specifically gave cam+mic permissions to some website fot test and they disappeared exactly when the notifications also disappeared. It took about 7 hours.

Workaround that works for me so far: always start Opera with the command-line flag --disable-features=DIPS.

Since I did that, my site permissions (notifications etc.) have stopped disappearing.

On Windows just add it in shortcut properties e.g.
"C:\Program Files\Opera\opera.exe" --disable-features=DIPS
If Opera gets started some other way (by clicking a link in another app etc), it runs without the flag.

Update: in my case there is a "second" way to stop the permissions from disappearing. Instead of using --disable-features=DIPS, I switched Settings > Privacy & security > Third-party cookies to "Allow third-party cookies". I ran Opera like that for a week and no permissions were lost.

When I switched back to "Block third-party cookies", they were wiped again within about two hours.

So the DIPS / Bounce Tracking Mitigations cleanup is tied to blocking third-party cookies: it only runs when they are blocked. With third-party cookies allowed it does nothing and permissions are not deleted. Keep in mind that allowing third-party cookies makes cross-site tracking easier, so the flag is the more privacy-friendly workaround.

This looks like a wired bug in Opera: the cleanup should only clear data of the tracking sites it flags, but it removes notification, location, camera and microphone permissions for all sites. I have just reported it to Opera with the details.

What puzzles me is how few users report this. Do people simply not notice, or are there other, rarer conditions involved that I'm not aware of?

It is very strange that this problem keeps coming back, just when things seem to be going well.

@MichaIng You said that

I installed Opera stable completely freshly, did not migrate my profile, setting or any such, and after some days/weeks of usage, the issue reappeared.

that's why I don't even feel like trying to set up a new profile

When I added this to my Opera startup link, permissions remained stable for maybe a week, before the issue reappeared.

I can check that, I'll try running the browser that way for as long as possible. It might not work, however, because the browser can be launched via other triggers without the -disable-features=DIPS flag.

It seems that from version 137.0.6036.39 is fine.

I noticed that in certain situations, the cursor briefly changes to one with a CD I've seen one like that a few times before, but too briefly to notice why.

Yes, I have exactly the same problem! Instead of zoom-in cursor it's busy and instead of zoom-out is nothing. Opera 136.0.6008.52 on Windows 11.

@burnout426 said in I'm missing the "Create search engine" entry:

Opera's context menu search engine enumeration just isn't set up to skip inactive engines yet. I consider that a bug.

I agree – it makes absolutely no sense for deactivated search engines to appear in the drop-down menu. It just ends up looking a mess after a while.
