When refreshing feed articles I sometimes noticed some error message
like "... is not valid.." flashing at the status bar, but it fades out
too quickly that I don't know which feed has problems. Are there some
ways to recall the error message?

there is an Info level message in the error console for
1) connection error/bad url.
2) the file at the url is not valid feed xml syntax.
3) the file has not changed since last check.

note that non intelligent servers don't send the 'Last-Modified'
timestamp and don't respond to 'If-Modified-Since' with a 304 code, thus
wasting bandwidth/processing on feed files that haven't changed.
publishers should be encouraged to always use those timestamps. a feed
that doesn't return 'no new messages' on an immediate second Get
Messages is...not intelligent.

no messages go to to Activity Manager. for extreme feeds logging, the
pref Feeds.logging.console may be changed to Debug or even Trace.

Thank you. There are many messages in Error console, in which "no
element found" error seems ignorable, since it always followed by "no
new articles". And other invalid links I have updated.

But it is really troublesome to examine through the Error console and
locate the invalid feeds message. I think a feature enhancement request
should be raised that show a ! mark to invalid feeds.

of course it is, and there is already such a request. it would be even
nicer to show the feed's favicon too.

There is a request about showing the feed's favicon (
https://bugzilla.mozilla.org/show_bug.cgi?id=745301 ), but I don't find
dead link notification request. So I created one:
