Incognito reg. hack no longer works with 6.8

Just4Me

I'm running the 32bit version for Win10. Today I updated from 6.6 to 6.8. Now the registry hack no longer works.

Briefly, it allowed ANY link that I clicked on to start in incognito mode. (Not talking about desktop shortcut).
It modified the shell for HKEY_CLASSES_ROOT\VivaldiHTM to enable this feature.

Now, after updating to 6.8, it no longer works. I double checked the registry to make sure it didn't add a new key for VivaldiHTM, and verified the exe path hadn't changed.

What has changed in this version to bypass the registry?
Hope someone has found a solution, would hate to uninstall and go back to 6.6!

@Just4Me Hi, far as I know nothing's changed and the --incognito flag works just like before.

In fact I just tested it here in Win10 with 6.8, and it opens a private window as expected. All I did to test was add the argument like this:
"D:\bin\Vivaldi\Application\vivaldi.exe" --incognito --single-argument %1

Any special reason you're still running on 32-bit? There might be differences and while 32-bit is still supported, it's definitely not recommended for several reasons.

I can't really test with 32-bit without uninstalling so that's not easy to test.

No, I'm not talking about command line or shortcuts. Incognito works properly there.

Make sure Vivaldi is closed. Go to an email with a web link in it. When you click on it, Vivaldi should open a private session if you have entered the registry hack..

Without the registry hack, it will just open a standard window.

@Just4Me Yes, was talking about the Registry of course.

Looks to be working fine here.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\VivaldiHTM]
@="Vivaldi HTML Document"
"AppUserModelId"="Vivaldi"

[HKEY_CLASSES_ROOT\VivaldiHTM\Application]
"AppUserModelId"="Vivaldi"
"ApplicationIcon"="D:\\bin\\Vivaldi\\Application\\vivaldi.exe,0"
"ApplicationName"="Vivaldi"
"ApplicationDescription"="Access the Internet"
"ApplicationCompany"="Vivaldi Technologies AS."

[HKEY_CLASSES_ROOT\VivaldiHTM\DefaultIcon]
@="D:\\bin\\Vivaldi\\Application\\vivaldi.exe,0"

[HKEY_CLASSES_ROOT\VivaldiHTM\shell]

[HKEY_CLASSES_ROOT\VivaldiHTM\shell\open]

[HKEY_CLASSES_ROOT\VivaldiHTM\shell\open\command]
@="\"D:\\bin\\Vivaldi\\Application\\vivaldi.exe\" --incognito --single-argument %1"

Do you see the actual --incognito argument in the command line of the launched process?

Just4Me

OK, your string did the trick! Thanks!

Previously the instructions were to REPLACE
--single-argument %1 with --incognito %1.

That worked up to 6.6, so maybe something changed in the later versions?

I have no idea, it's always been like that for me.
Did a quick search, found something, but it must've been there for years.

Hi,
Where are those instructions?

Just4Me

I couldn't find the original site stating it could be done with any browser. But It worked with Chrome, Brave, and Vivaldi.

I tend to make brief notes in case I can't find an old site later, or it goes offline. If you can find the exact site, let me know.

So this is the closest I could find:
