I'm setting up my Mac OS firewall, the most current version, to maximize my Firefox security.

I've enabled Stealth Mode and Automatic Updates with certifications.

But I'm wondering about what other stuff to block. I don't want to cripple myself with stuff like automatic updates to software, etc., but I don't want to leave a backdoor for anyone to come snooping around either.

Or should I get some other firewall software that gives me more control?

Opinions?

In our organization we are using a firewall which has an Intrusion Prevention System. The IPS has a certificate which must be imported into the browsers to be able to load SSL websites. This allows the IPS to inspect the contents of secure packets for any malware or viruses. The problem is this isn't working very well with Firefox. Most secure sites bring up one of the following errors:

Secure Connection Failed The connection to <website> was interrupted while the page was loading. The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

OR

Secure Connection Failed An error occurred during a connection to <website>. SSL peer rejected a handshake message for unacceptable content. (Error code: ssl_error_illegal_parameter_alert) The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Does anyone have any suggestions on how to get Firefox to work in this environment?

I forgot that I need to use my iPad email. My desktop is not speaking to the Internet this week. Troubled shooters are no solution. The closest I can come to the problem is a home page message on chrome. It says "DNS probe finished no internet" not much to go on for me anyway. Appreciate any help anyone can provide. I suspect a proxy problem, but that is way over my head. I am old in years and new in computer talk, so be simple in steps to solve. Thanks. George sends.

I've been using Firefox as my primary browser for years with no issues. A couple of days ago for no apparent reason, it will no longer connect to ANY website. The tab indefinitely shows "Connecting..." with the spinning circle. I can use IE and Chrome with no issues. I've double checked the Options -> Advanced -> Connection for proxy settings and tried every option but to no avail. I've also started in Safe Mode and still nothing. Also tried uninstalling and reinstalling several times. I'm on version 42.0

Surely there must be a way to debug this to figure it out.

I used Firefox for several hours to do my taxes, etc. After completing all my work for the day, I did my usual weekly "cleaning". I cleared my history and cookies from both IE and Firefox, ran disc cleanup, and ran my virus scanner. The computer was shut down for several hours. Now when I open Firefox, my set home page comes up; however, nothing else works. Clicking on anything (including my favorite list) causes the browser to stop responding. When I type a URL into the bar and click enter, nothing happens. In short, Firefox isn't working at all and I'm not sure if something I did caused the problem. An extra fact, I did download Firefox again, but that didn't fix the problem.

I have an imac that I just upgraded to el capitan. now when I open firefox nothing will load until I select another open program. Once I select another open program the webpage instantly appears on the browser. basically inorder to get anything to load or to see what I have typed, I have to select another open program and the info appears. Also, the very top of the browser window is cut off. I have attached a screen shot.

It frustrating because I have to constantly keep jumping back and forth between any other open window and firefox in order to get anything done.

help!

When I configure my Firewall on Windows to allow outgoing connections only for firefox.exe, then Firefox hangs during startup and comes up after 30 or 60 seconds.

When I let all traffic pass through, it starts immediately.

I cannot see any listeing port in tcpview. So I wonder: Why does firefox hang when only outgoing connections are allowed?

I am having issues where my Firefox will not even open at all.

The application crashes and shows an event in the event viewer as attached.

The event is:

Faulting application name: firefox.exe, version: 50.0.0.6152, time stamp: 0x581d78ba Faulting module name: HcApi.dll, version: 8.0.0.3753, time stamp: 0x570e61e2 Exception code: 0xc0000005 Fault offset: 0x0000cc18 Faulting process id: 0x1cc0 Faulting application start time: 0x01d24981a551e219 Faulting application path: C:\Program Files (x86)\Mozilla Firefox\firefox.exe Faulting module path: C:\Program Files (x86)\McAfee\Gkp\HcApi.dll Report Id: 960b12ee-1934-47b5-8390-3745a2595c6f Faulting package full name: Faulting package-relative application ID:



Basically if I turn off my firewall in McAfee Security Centre, Firefox will open perfectly normal.

Not sure if this is an issue with McAfee or FireFox but I think it's still relevant.

I'm on Windows 10 with the Anniversary update and both McAfee and Firefox are fully up to date as well as Windows.

hello, just updated to version 62 (x64) and everything become very very slow. It needs at least 18 seconds to open and the same time to open just a new tab

before the update everything was good enough, now I uninstalled it completely with Revo, cleaned the registry with Wise, cleaned the PC with CCleaner, optimize the SSD and installed the previous (working) version (61): SAME SITUATION, IT'S UNBELIEVABLE SLOW.

After the new installation, without any plugin installed: very slow. With the plugins installed: the same

What is FUNNY is that's not happening on a cheaper system! What is FUNNY is that it's not happenyng on just ONE system!

Sys 1: Laptop with Intel i5, 8Gb RAM and SSD Samsung Sys 2: Desktop with Intel i5, 16Gb RAM DDR4 3600MHz, 256Gb SSD Samsung NVMe and Geforge 1080 8Gb

You'll understand that with any of those system in your hands, waiting more than 2 seconds to see the browser open IS ABSOLUTELY UNBELIEVABLE!!!!!!!!!!!!

The last update corrupt something, otherwise the previous working version didn't works so badly

Now I'll restore a ghost image, fortunately I have it at least two for each month, in the while I'll test other faster browsers

These do load without problems: https://www.google.de/ https://www.google.at/ as well as any other website I've tried

What I've tried so far: - Safe Mode - Firefox Refresh - complete removal of Firefox and profile, re-download, fresh install - switching between wifi and cable connections

No other browser on my system has these issues, testet with Safari, Chrome, Vivaldi

I do remember having this issue on 62.0.3 too...

Thanks for any pointers.
