How to re - activate the FF 29 Add-on compatibility check
Several weeks ago, I installed FF 29.0.1 on two virtually identical XP systems. I have been carefully maintain extensions, settings, etc., in parallel on both systems.
Initially, my main system told me if an extension in my search list was incompatible with 29.0.1, and no doubt, that's what I want to do.
However, I recently installed a couple of extensions, which seemed to work very well. (I had downloaded installers and then installed in the files.) Then, when I tried to install from the same files on the second system, he told me that they were incompatible with 29.0.1, and that they could not be installed.
I would like to re - activate the verification of the compatibility of the system on which it seems to have been turned off. I tried FF forums at length, but may not know all the information about: config or other settings may have an impact on this.
The error message that I get on a system when trying to install some extensions is a small box of drop-down menu of green extensions Manager icon near the top left corner of the screen. However, it disappears when you press the 'Print screen' key and does not appear in the captured image. I noticed this kind of weird on some other sites. So, it seems impossible to get a picture of the message. The message may be re-displayed, but not printed, by clicking on the green icon. However, the text of the message, ' < name of the extension - > could not be installed because it is not compatible with Firefox 29.0.1.» Note: It is easy to reproduce this message, temporarily turning on extensions.strictCompatibility and tries to install older extensions.
In any case, the system on which I was getting the message now behaves identical to my other system, apparently without any change of parameters. Therefore, I believe that it was a persistent but temporary problem that may have been fixed by a reboot. Therefore, the problem seems to be resolved.

How can I activate the Defender manually
can someone help me please on how to manually activate the Defender? I get an error message.
Im not COMP not saavy so if someone can help me step by step I would really appreciate it please
Hello
If you use Norton, AVG, Avira, Microsoft Security Essentials, McAfee, etc. the default action is for Windows Defender must be disabled, that these AntiVirus programs have their own Antispyware Applications.
There is nothing to worry.
Using both programs at the same time can cause system conflicts, etc.
If you are using one of the above AntiVirus programs, this Information from David O - Support Engineer shows you how to manually enable Windows Defender (disregard information from uninstalling; not possible in Vista):
"Go to start, Control Panel, Administrative Tools, Services. Look for Windows Defender.
Right click and select Properties , ensure that Startup Type is automatic.
Once modified, click apply and OK.
Quit and restart your computer. Check the back take the same path to confirm that Windows Defender has started"
.
If you want to have additional protection against malware using the version FREE of Malwarebytes AntiMalware:
http://www.Malwarebytes.org/products/malwarebytes_free
And for now, change startup Vista programs without using Defender, use one of these methods:
"How to use MSCONFIG in Windows Vista"
http://netsquirrel.com/Msconfig/msconfig_vista.html
Or the program Autoruns for FREE:
"V11.21 Autoruns for Windows"

See you soon.

I got the last part of what you wanted, which was simply not the message
The key is that you have to allow this program through your windows firewall.
Go to your look for the windows Firewall Control Panel,
There should be a list to allow a program through windows firewall, look at the top left.
If you feel safe doing this, vlc is not one that I would feel safe with, but to you, it has a function to browse to find the program to be added to your trusted list or access through your firewall.
Still, it may give you a warning but could release the message?
