Firefox has arbitrarily disabled IDMcc even though I have been using it multiple times a day for months with no problems. I wish to reinstall IDM and use it. If I can't I will stop using Firefox and go back to IE. I would prefer to stay with Firefox but I will not use a browser that won't let me use IDM which was working just fine.

== I reloaded Firefox I told IDM had been disabled

Chosen solution

This was a typo in our blocklisting. IDM causes Firefox 4 and up to crash, we accidentally blocklisted it for 3.6+ instead. This has already been fixed, you should be able to re-enable it via Tools > Addons now.

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.

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.

Then, those in desperate need of the extension may wish to attempt the following fix listed in comment 34 of the above bug.

I would urge caution if you attempt this however. I am not a Mozilla employee, and so this workaround should not be taken as official advice. If you do not completely understand the instructions in comment 34, do not attempt the fix as you risk causing further problems with your browser. Please try to be patient, and Firefox should resolve the situation itself within 24 hours, as stated.

I hope that a workaround of this nature is permitted for posting on this support forum...

Tengo el derecho a decidir si usar el complement o no. Es mi ordenador asi que si quisiera ejecutar el más mortal de los virus estoy en mi derecho. Mi ordenador no les pertenece asi que vuelvan a activar la compatibilidad con el complemento, mientras tanto regreso a IE.

Firefox is the most popular and trusted browser right now and that what leads them to other competing browsers in terms of users. But hey, Firefox is not irreplaceable.

More detailed instructions on reaching about:config and disabling the extension blocklist feature are available here.

To try Gustavo's fix: - Type about:config in the address bar - Scroll down until you find extensions.blocklist.enabled - Look across to the value column - If the value is true double click or right click and click on toggle - This will change the value to false - Restart Firefox and all the addons that Firefox has disabled will be back - If you are smart you will have made note of any other addons which Firefox has disabled before this. You can then disable them again - If you are dumb like me you will forget to do this and you will try in vain to remember which other addons had been disabled

i think IDM add-one doesnot support the new Firefox 3.6.7 :( So for the solution wait for the IDM next update........ :) because, i`ve checked today but there was no update available.....

Another Solution :

Goto Add/Remove

Remove Firewfox 3.6.6 then download & install the old version from filehippo (3.6.6) IDMcc will work fine..... and when IDM will release its new update then update your firefox :)

Here is an effective solution:

in the address bar type about:config . Click the button "I'll be careful I promise" . Find extensions.blocklist.enabled . Change it to false zith a double clic. Close out and restart firefox. IDM will be back enabled. I tried it and it succeeded.
