Run the Chromium-based and Presto-based Opera on the same system?
Is it possible to install the new Chromium-based Opera browser but still have the Presto based Opera (Version 12.17, Windows) installed too?
(Would the Chromium-based Opera overwrite the settings of the Presto one?)
Not a problem at all, I do it myself.
I installed the new Opera into a different folder for neatness, but the two versions can co-exist even in the same folder.
You should be offered the option to copy your bookmarks across from the Presto version to the Chromium version, but only if you install into the same folder AFAIK.
