Status: RESOLVED DUPLICATE of bug 198291

It happened when I wanted to delete the mails in a folder, which get too fat.
(Actually there was 463 mails with not attachments, so may not be so "fat".)

While selecting the mails, and add or reduce some of selection, I pressed
Enter button instead of right Shift button. Mozzila mail/news and browser
running behind both freeze, "not responding" to OS, even couldn't kill with
the task manager. (Only "logging off" or "shutdown" was the solution.)

Later I experimented with this folder.
1) when you select 1 mail, and press Enter, it opens the mail in separate
   window.

2) when you select 2 mails, and press Enter, it opens both mails in separate
   windows.

3) when you select more mails, and pess Enter, it opens all mails in separate
   windows, wich support to be correct behavour, not bug, but there is certain
   threshold, that maybe due to insuficient memory, that Mozzila can't open 
   the mails. It tries, but becomes too busy, not responding, even can't offer
   canceling the operation.

It's basically my wrong operation that causes the problem, but it would be
fine, if Mozzila could warn me, when too much messages are selected when
I pressed the Enter button, since in normal situation, users wouldn't want
to open 100 mails in separate windows at once...




Reproducible: Always

Steps to Reproduce:
1. Select many (in my case 463) messages in one of my folders
2. press Enter
3.

Actual Results:  
The entire Mozzila freezes.

(I don't know if I should chose Normal severity, or Critical, since 
 the data in the browser maybe lost, or Request, since it was caused
 by the user's mis operation...)


Expected Results:  
(maybe) Warn that it may be too much, or it would take a long time, 
or it will try to open all the messages in separate windows and 
may be Mozzila will freeze.

(maybe) just block the activation for over 100, or 50, or 20 messages
at once. With a error/warning message.

Similar to bug 193351, but not a dupe.

bug #198291 (qualified as dup of #193351) is almost same.
So this report will be also the dup of #198291?

You're right; I had missed that.
