I've been offline and unable to update the blog for a while
(technical glitch, long story) but I'm back and have several
stories to polish up and post, beginning with this helpful
(I hope) Firefox tidbit:
I've often wanted a way to get Firefox to save the current set of tabs
without actually bookmarking them -- the way it does when you install
an extension and need to restart. But I'd never found a way to do that
through the menus.
But then I realized that I could use the same trick that I use for
landscape
printing:
- Edit user.js in your Firefox profile directory, and add
this line:
user_pref("browser.tabs.warnOnClose", false);
This will ensure that normally, it doesn't give you the confirmation
box, only when you ask for it.
- In your running Firefox, go to about:config and search for
tabs
- Look for the browser.tabs.warnOnClose line and doubleclick it
(change it to true)
Now you'll get the confirmation dialog when you quit this session.

I discovered a handy tip for Linux Firefox' printing Page Setup today.
Normal web page printing uses "Portrait" mode: you read the page
with the paper oriented so that it's taller than it is wide.
Once a week, I need to print a form from a club web site to bring
to the meetings. It's a table that's much wider than it is tall,
so I want to print it that way: in "Landscape" mode.
In Firefox 2 (at least on Linux), you can't do that from the Print
dialog -- there's no Portrait/Landscape option. So you have to use
a separate dialog, Page Setup, following these steps:
- Run Page Setup
- Change Portrait to Landscape
- Click OK
- Print (bring up the Print dialog and click OK)
- Run Page Setup
- Change Landscape to Portrait
- Click OK
Kind of a lot of steps just to print one landscape page!
But if you forget,
the next page you print from Firefox will be printed in Landscape
mode and will take twice as many pages as it should (if you don't
notice what's happening and dive for the printer's OFF switch in time,
that being the only way to cancel a printing job once it hits the printer).
This morning, it finally occurred to me that Firefox was storing this
setting somehow, most likely in prefs.js.
If I could find the setting and force it in user.js (which takes
precedence over prefs.js and is not updated by Firefox), I could make
Firefox set itself back to Portrait every time it starts up.
(prefs.js and user.js are both generally found in $HOME/.mozilla/firefox/).
Some greppery-pokery revealed the solution.
I needed only to add a line in user.js that looks like this:
user_pref("print.printer_CUPS/Epson.print_orientation", 0);
and presto! my problem was solved.
Oddly, it's set separately for every printer you have defined, even
though there's no way to set one printer to Landscape while another
one is still on Portrait (the Page Setup dialog is global, and applies
to every printer Firefox knows about). "Epson" is the CUPS name of my
primary printer; replace that with your printer's name (as set in
CUPS), and add a similar line for each printer you have. For the
printers I've used, 0 is Portrait and 1 is Landscape, but you can
verify that by typing:
grep orientation prefs.js | grep name
That command will also help you
if you're not sure what printers you have defined, or you don't use
CUPS but want to try this under a different print spooler.
(Don't be misled by all the orientation prefs with "tmp" in the name.)
As a minor digression, there's actually a secret pref that's supposed
to give another way around the problem:
user_pref("print.whileInPrintPreview", true);
This lets you do all your printing from the Print Preview window,
which offers its own Portrait and Landscape buttons. That would
be a nice solution. Alas, the Portrait and Landscape buttons in that
dialog currently don't work, and since this preference is undocumented
and unmaintained, filing more bugs isn't likely to help.
(I should mention that this all pertains to Firefox 2.
I haven't switched to Firefox 3 yet,
so I don't know the state of its printing UI, or whether this
preference is either helpful or effective there.)
