Hi,

There is a correction to this bug.  You need only mouse-over the bookmark for it
to freeze FireFox.

Steps to Reproduce:
1. Open up Firefox
2. In the Address bar, type C:\winnt, and press GO button.
3. Press <CTRL>D (or go to Bookmarks, and click 'Bookmark this page...'
4. Click OK
5. Go to bookmarks, and mouse-over your new bookmark.
6. Freeze

Actually, its just painfully slow.  If you wait long enough it does come back.

Looks like a dupe of bug 98682.

Comment 4

[Michael Freymond]

I do not think it is a duplicate of bug 98682, as firefox is very slow/hangs
regardless if the host is responding or not.

reproduced on w2k
doesn't happen on my XP machine 
But XP machine is much faster with fewer shares, so my test results are suspect

however, impact is hardly critical.

a hang is a critical bug.  Still most likely a dupe, but I don't have time to
search.

My bad. I misread the impact. And I retract my comment about recreating this on
w2k - I only had a 5 second wait, no hang, and it doesn't happen on mouseover

Is this only happening on 1.0+ and not the trunk?
Does it happen from bookmark manager and sidebar?

This is occuring in the public 1.0 release (this is where it was first noticed).

I am running W2K SP4, and it is occuring.  My laptop (running Windows XP SP1,
there is a delay (5 - 10 seconds), and it then shows the contents of the
bookmarked folder.  Subsequent visits to the bookmark have little to no delay.

It appears to me (who doesn't really know much about this stuff - feel free to
correct me) that FF is browsing the folder through the bookmark menu.

FF is building the entire directory (all it's subfolders and files) into
bookmarks. That's a lot of IOs, delay is to be expected. To prove this, open
task manager (ctrl-alt-del) and add the IO reads column via view>select>IO
Reads.  Now open the folder from the personal bookmarks toolbar in Firefox and
you'll see tens of thousands of IOs. The bigger the directory and it's
subdirectories the longer the wait (I dare you to bookmark c:\)

I can't replicate a hang or freeze with 1.0 or any other variation of FF.  And
based on your accounting above you do not have a freeze or hang, just a delay -
correct?  

This is headed to be resolved as INVALID, unless someone documents a true hang
stating their hardware config (memory, etc) and details of how long they waited,
etc.

(Now ... I found some abberant behavior - if this bookmarked folder is in the
bookmarks toobar but "falls off" the right of the browser window it behaves
differently.  Make your window narrow so it falls off the right side, then click
the ">>" and select the bookmark - you now get the windows folder in the
browser, not a drop down list of bookmarks.)

sorry for bugspam, long-overdue mass reassign of ancient QA contact bugs, filter on "beltznerLovesGoats" to get rid of this mass change
