Today I learned something new about Fire Fox 3.6.17. I was migrating a SSL EV certificate from a IIS server onto a Virtual Server that is located on a KEMP LoadMaster. This test server on the LM is running a prototype/test site. Therefore, the domain name doesn’t match the domain name that the SSL cert was created for. This normally will create a SSL name mismatch error in the web browser. This error normally can then be bypassed by the user, this process is called “Security Exception” in Fire Fox. I went to add this exception and found that Fire Fox wouldn’t allow me to add it. What’s interesting is that the exception window tells you that the identification of the certificate is so positive that there is no reason for you to add an exception.
This site provides valid, verified identification. There is no need to add an exception.
I think this is a good thing. It really helps make the EV certificates more strong and adds value to them. I guess I’ll go back to using a self signed certificate for testing.
I like to use older and slower hardware to browse the web, etc. These machines have no problems doing this job normally, so theres no reason to replace them and add them to landfills. Just install your Linux distro of choice on them and you are ready to surf (virus free, I might add).
However, there is one thing I have found to consistently detract from my browsing experience on such machines: Flash Ads
These awful and useless pieces of marketing usually waste a huge amount of processing power on nothing. Often I will see them playing animations and things while they burn through almost 90% of CPU power. It’s sad even to imagine how much electricy they waste in causing the processor to run at such a high load. Yikes, just imagine that number multiplied by all the people in the world browsing to sites that use Flash Ads.
Well, if you’re like me and you think enough is enough. Here is how you can block them on your browser.
You must be using Firefox. (If you are not already using Firefox, you should start using it immediatly. Firefox is one of the most secure browsers.)
Install the extension: Ad Block Plus
Once it is installed, you need to add a filter for Flash. Click on Tools -> Add-ons -> Extensions -> Preferences -> Add Filter -> *.swf -> OK
This will block ALL flash content. Obviosly, you can fine tune this to only block certain really annoying sites, etc.
