And, gods above, what a hog that is. In part, the 1/3 gigabyte of
resident set size was attributable to having eight tabs open. Close
seven of them, and, sadly, RSS does _not_ go down. Close it and open a
new browser instance with no page loaded, and I get (quoting "top"):
RSS = 45 MB
SHR = 17 MB
VSZ = 136 MB.
This is, however, not a barebones Firefox v. 3.0.6. It has these
User Agent Switcher 0.6.11
All Firefox extensions are interpreted code written in XUL, and seem to
be not exactly RAM-saving.
Someone trying to save RAM would absolutely not run those extensions.
If barebones Firefox still doesn't cut it -- as might be the case for
128-256MB decade-old boxes -- then you would have to look at mostly-OK
smaller alternatives: BrowseX, Dillo, Minimo. I'd look at them in that
I could also save a _big_ load of RAM by substituting mutt for "icedove"
(Mozilla Thunderbird), and may eventually do so.
