Instead of installing multiple copies of Opera, you can create multiple profiles with single installation.
You can use another profile to
- login to another accounts of a site simultaneously. (Another way is using private tab.)
- load a site that crashes Opera frequently.
- play with settings without affecting existing profile.
- check whether there is a problem in existing profile.
- separate work from personal browsing.
Before Opera version 12, you have to create another profile manually in Windows OS, but now you can create another profile on the fly with the
-pd switch similar to Linux OS.
You can create a shortcut with the following code or copy & paste it in run dialog box, Win+R to create new profile and/or run Opera.
The following will create opera-profile settings directory inside Temp directory.
"%PROGRAMFILES%\Opera\opera.exe" -pd %TMP%\opera-profile
If you specify profile directory name without path, Opera will create that directory inside Opera installation directory. This will be useful with single user profile or stand-alone installation (USB).
The following will create profile-2 settings directory inside Opera installation directory.
"%PROGRAMFILES%\Opera\opera.exe" -pd profile-2
You can add the following menu items under [Document Popup Menu] section of existing profile menu setup file to run or open current tab in profile-2.
Item, Run Opera with Profile-2 = Execute program, "C:\Program Files\Opera\opera.exe", "-pd profile-2" Item, Open Current Tab in Profile-2 = Execute program, "C:\Program Files\Opera\opera.exe", "-pd profile-2 %u"
