I'm using Fedora and I've just now downloaded Opera, its awesome . But I've got one problem and that is when I switch to New Workspace and open Opera (new Instance), it will not be opened in present Workspace but opens up Speed Dial tab in the previous Workspace next to current browsing tab and this is creating problem while browsing, I need to move the Current browsing session windows to next Workspace or stay in only one.

My About Opera revealed the following information:

About Opera
Version information
Browser identification 
Opera/9.80 (X11; Linux i686) Presto/2.12.388 Version/12.16

So how can I open Multiple instances of Opera in New Workspaces? Let me know, Thanks in advance...

This question came from our site for professional and enthusiast programmers.

You left unclear, which window manager/desktop environment you are using.

Assuming you use Gnome, you can do the following:

Navigate to ~/.gconf/desktop/gnome/url-handlers/, do a grep -r opera *, which should output something like this:

about/%gconf.xml:       <stringvalue>opera -newpage %s</stringvalue>
http/%gconf.xml:        <stringvalue>opera -newpage %s</stringvalue>
https/%gconf.xml:       <stringvalue>opera -newpage %s</stringvalue>
unknown/%gconf.xml:     <stringvalue>opera -newpage %s</stringvalue>

Open these files with your favourite editor and change all those -newpage (or whatever value your files show as options) to -newwindow. Keep in mind, that now every link you open from outside Opera will open in a new window/instance, only links opened from within Opera will open in the same window.

I guess this is not quite the answer you were looking for, but as far as I know, there is no (convenient) way you can probe for an already running instance of a window on the same desktop to differentiate this behaviour.

neither -newpage nor -newwindow work with 33.0.1990.43 (also tried double dash) – TheOne Oct 30 '15 at 16:47
