All of a sudden today I get an error message when I try to print a Gmail
email via Firefox on XP. Says
"Grrr! A popup blocker may be preventing the application from opening the
page. If you have a popup blocker, try disabling it to open the window."
I don't recall using a popup blocker. I have no idea what happened. I
didn't purposely change anything. What can I do about this to return to
printing emails?
TIA
Besides what Paul mentioned about disabling all extensions and
retesting, many extensions and tweakers change settings in Firefox that
are still effected with all extensions disabled and even when starting
Firefox in its safe mode. Neither of those diagnostic steps eliminate
effects from changing settings. If disabling all extensions doesn't
work, and if starting Firefox in its safe mode doesn't work, try
resetting Firefox. The creates a new profile with all the default
settings, and no extensions yet installed.
Did you test with temporarily disabling your anti-virus program?
Have you opened a private session in Firefox and testing using that?
Even if you don't install any adblock or other content-modifying
extension into Firefox, it has its own internal blocklist. It should
not be interferring with a print dialog, though. Mozilla incorporated
the Disconnect.me blocklist into Firefox, and why the Disconnect add-on
is superfluous. That is a very weak blocklist. The number of entries
is dismal. When you visit Gmail, look at the left-side of the address
bar for a shield icon. If gray, no known trackers or harmful scripts
were detected on the site. If gray and crossed out, Enhanced Tracking
Protection (ETP) is enabled on a site (likely you choose to disable it
on the site using Site Preferences). Click on the shield to see more
info. If the shield is purple, ETP is enabled AND it blocked trackers
and suspect scripts on a site. Click on the shield to get more info.
The old option to enable/disable tracking protection is gone. You now
have to go into Options - Privacy & Security - Enhanced Tracking
Protection, and disable what you want by selecting the Custom config
where you decide what to block. You could try the Standard level (in
case you were at the Strict level) to keep some protection to see if the
site then works correctly. The only difference that I've found between
Standard and Strict is Standard allows trackers with inprivate sessions
(but then wipes that data when you exit the inprivate window) versus
Strict that blocks trackers in both non-private and private sessions.
Allowing trackers, even in a private session, means tracking can be
achieved within that private session, but not between private sessions.
Up to you if you want to allow trackers while surfing using a private
session. You could also click on the purple shield to change protection
for just that site. I use Strict mode, and change a site's preferences
regarding ETP if I feel I can trust the site or really need it to work;
however, I configure Firefox to purge EVERTYING on its exit, so the
worse would be some tracking occurs /during/ a non-private session.
Because I use uBlock Origin, I first thought ETP was superfluous,
especially since the Disconnect.me blocklist is so small. However, ETP
also blocks cryptominer and fingerprinting sites that aren't covered by
any of the blocklists (e.g., EasyList, EasyPrivacy, AdGuard). More info

When printing, are you using Firefox's Print function, or somehow else
doing the printing?
Did you allow Firefox to update itself, but have to restart it?
