[sf-lug] any way to avoid firefox jumping to current workspace when clicking on a link in e.g. thunderbird?

[Michael Shiloh]

i like to keep email and browsing on different workspaces. however, 
whenever i click on an http url in thunderbird, firefox bounces over to 
the current workspace.

i want firefox to open the url, but to stay in its own workspace.

anyone know how to do that?

(in case you remember my recent queries, i'm typing this on my 
refurbished t61p running xubuntu. so far i'm happy, although i do have 
the nvidia gpu known to have overheating issues. i have 7 days to return 
if i want, and beyond that the one year warranty. not sure what i'll 
decide.)
