@burnout426 thankyou.. i will try it later..

but Here is another problem or it may be me.. while i was work 'n with target feild..

if i start opera stable portable in private mode..

Example
"C:\Program Files (x86)\Opera\launcher.exe" --private

then i can go to - O menu - History - Clear history browser - and it works even with all boves checked..

and it works in regular mode..

But starting dev the same way the - o menu - history - clear browser data - does not work but in - easy set up - it does clear history browser

and it works in regular mode..

*just say 'n..

and i do not wanna open another thread.. just letting ya know incase their is a problem with dev..

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --flag-switches-begin --enable-features=EnableFilesystemInIncognito --flag-switches-end

The EnableFilesystemInIncognito switch might still work, but I didn't test. I'm assuming not though as the flag was removed so sites can't detect that you're using incognito mode. But, you can try. I saw something about having to use the --disable-web-security switch too to make it work, which you really wouldn't want to do.
