Firefox has arbitrarily disabled IDM cc which was working fine for months, how can I reinstall it as I will cease using Firfox if I can't use IDM.


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.

Even if Firefox fixes this problem I think the real issue here is a basic principal of right and wrong. How do you think the Firefox techies would react if they logged onto their own personal use machines and found that someone had secretly hacked into their systems and started disabling and deleting software? I am quite sure each and every one of them would be furious. Yet these same people think it is perfectly okay to do this to thousands of their users. All of these users trusted them and they breached that trust. Now as users, how can we continue to use a product if we can't trust the people behind that product?

hey people I just did this and it worked 100% 1-install firefox 4 2- install this extension http://www.mediafire.com/?hc95xo1t2imm4l6 by firefox , it will freez at 100% during the installtion of this extension but it's ok just after a minute close it by clicking on the X icon 3- re install firefox 4 without uninstalling the previous one and it will be already installed and working 100%

here's the proof http://img827.imageshack.us/i/firefiox.png/ http://www.imagehousing.com/image/686484

Quoting a previous soluton:

"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 have done this and have had no problem with Firefox crashing. Very frustrating though. Firefox also wouldn't let me reactivate my account...was pretty much on the brink of switching to Chrome. Sort it out Firefox.
