STABLE version -- 5.1.1130.123

[Admini]

version 5.1.1130.122: 'Search google for "xxx"' in contextmenu open result in current tab instead of open new tab. It has same behaviour as search in address bar when I change "Open search result in..." in tab options
Any problem if I downgrade to version 5.1.1130.82 without delete User Data folder? Thank you

They are based on the same Chromium version, you can overwrite each other without worry.
