Hey pleasse help, i need that plugin to work! My internet connection really sucks and it helps me get my antivirus updates etc faster.

Situation/Fix-

The block was in error, and should have only applied to beta versions of Firefox 4.0 due to the large number of crashes it caused on that version. However, a programming error resulted in the extension being blocked on all Firefox versions.

The change has already been rolled back according to Bug 578433 listed here.

https://bugzilla.mozilla.org/show_bug.cgi?id=578443

However, browsers that have already blocked the extension may not immediately register the change. All Firefox browsers connected to the internet should have unblocked the extension within 24 hours, to my understanding.

"I need a fix for this right away though!"

First, restart your browser and see if the block persists.

Second, a new possible fix was just posted in that bug which may enable you to update your blocklist on demand, thus re-enabling the extension. Please see Comment #35 (directly linked).

Those in desperate need of the extension may wish to disable the extension blocklist functionality in Firefox, which should re-enable the extension (according to reports unconfirmed by me).

Instructions on how to do that are provided here.

I would personally encourage re-enabling the extension blocklist in a day or two, as it normally provides a valuable defense against the possibility of dangerous extensions being run.

Copy and Paste this code in the Code field in the "Tools > Error Console" and click the Evaluate button to refresh that list.

Components.classes['@mozilla.org/extensions/blocklist;1'].getService(Components.interfaces.nsITimerCallback).notify(null);

The solution is: install the idm 6.04 of http://thepiratebay.org/torrent/6069471/Internet_Download_Manager_6.04_Build_2__Serial_%5BUT%5D.htm
