Unable to connect to proxy due to automatic https

Hi there,

I am the network administrator for an Australian K-12 school. We are cross platform, and support both Mac & Windows environments, based of an Active Directory Infrastructure.

We have local proxy server based on ISA 2006, using McAfee SmartFilter as the local filtering solution.

The issue I am having has been occuring since Firefox 12 was released. A number of websites retrieved through firefox started using the HTTPS connection by default, for example google.com, youtube.com, twitter.com, or carrying out a search using the search bar.

For example - If i search cat in the search bar, Firefox will automatically refer the search through this url - https://www.google.com.au/search?q=cat&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-GB:official&client=firefox-a&channel=fflb.

With the majority of our Mac computers running Firefox 14 or later, this search is hampered and returns the message Proxy is refusing connection. To overcome this, I have trained staff and students to remove the 's' from http:// and to reattempt the connection. If it isn't a blocked term, ie porn, the proxy will ask for login details, and connect through.

In the case of a blocked website, such as YouTube, the same fix is applied to bring up the block page, which can allow the override. Further more, once the filtering is turn off. The issue doesn't rear again, until the filter cuts back in.

This also occurs, but less often with our Windows based computers running Firefox, as they support NTLM authentication straight through.

What makes it most curious, is that Safari versions 5 & 6, the current and many releases of Google Chrome, and Internet Explorer 7, 8 & 9 work flawlessly.

I'm looking for an option or a fix that will allow us to set a preference the HTTP over HTTPS for these website so that Firefox can at least work straight out, prior to the release of this feature, or adjust so that if the connection is refused/unable to connect by the proxy at, it will try by HTTP before failing to connect.

If there is anything else I can try, please let me know.

Quite often I receive a message after clicking on Firefox saying 'Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.' Why does Firefox not close properly and the process stay running?? I am seriously thinking of moving to google chrome and abandoning firefox because of this error. It isnt my system because it happens on my laptops and friends computers too. I could expect the odd crash with firefox but not as many as I am experiencing. I normally get this error around 4 to 5 times a week

I have used Firefox for about 7 years. No issues... I recently installed Ghostery add on.

The only way to describe it is: I go to a page.. Click a link (or close to it) or enter or any other button/link that would take me to what I expect..

BUT instead it opens a new tab to an advertisement site (quibids, P&G, many other random ads) - a few of them I blacklisted with BLOCKSITE (installed after the problem started happening) but several I can't because I would actually use them when I need to (ex: Vistaprint.com)

When I go back to the original site and click the same link and click it again it works as intended. This happens across all sites that I am on... It is like there is a hidden link within the one I am clicking on. I have pop ups blocked in my browser but this gets around it somehow.

Since GHOSTERY installed, some sites do not work correctly. If I click on a picture, or something that I want to expand it is as if I am doing nothing at all because it won't complete the action, the functionality is broken.

I have white listed a couple sites but this is random and if I whitelist everything I come across then it opens me back to what I am trying to avoid..

EXAMPLES:

went on Heat.com, clicked the button to go to the White Hot Gear instead it opened a new tab brandonline.com

was on LinkedIn and hit the comment button on a thread, then it opened a new tab vistaprint.com

was on publix.com, hit the order refills button, then it opened a new tab premium-promos.net

did a google search clicked on the link I wanted, it opened a new tab premiumgiftrewards.net

EACH time I go back to the original site and click the same button/link/etc it takes me where expected.

Thanks in advance for your help!

I've already cleared all of my history (pressed ctrl + shift + del and cleared everything, including active log-ins, site preferences, and cookies), I went on the security tab under options and tried deleting all saved passwords, and I've tried restarting the browser, but when I go to the facebook url, it still automatically lists my username and password. I've tried finding another solution, but all people keep saying is to clear history (which I've already done) and change saved passwords under the security tab (which I've already done).

Are there any other options?

I'm using Windows 7 Home premium on an HP Pavilion laptop. Maybe two weeks ago, I stopped being able to create new folders in the Windows Explorer box; I click the "New Folder" button, and nothing happens: no error message, nothing. Around two weeks ago, I also reinstalled Firefox to get rid of some adware virus (success: the adware is gone!). I do not recall the exact timing on when I did the reinstall and when I stopped being able to create new folders, but I'm wondering if the folder problem could be related to the re-install. And if so, what can I do about it? Thanks so much for any help you can offer.

This isn't as much of a support question as a design decision question. I know that WebM is to remain open, and h.264 isn't sure, but from what I can tell from these results:

http://www.streamingmedia.com/Articles/ReadArticle.aspx?ArticleID=68594&PageNum=1

The CPU usage difference is immense, which honestly is an issue for a lot of PC's. h.264 is way lower on CPU usage, and seems to be superior overall. Are there any plans/talks to move that to being an open standard, and will Firefox ever support it?

I understand Firefox is an open source browser, but that doesn't mean it shouldn't support some standards if they are as dramatically superior as this, even if it wont always remain open, drop it at that time instead of just not picking it up.
