Look in IE to get your proxy server certificate. Mostly it will be with your company's name.

Export it and import it in Firefox. Once that is done edit the trust settings for the certificate to allow it to identify websites. I think its in the authorities tab in options for Firefox. You should be good to go after this...

Hope it helps.

The reason this happens is because organizations sometimes want see and track activities on secure sites of their associates if they want to. They bypass the original certificate and put their own.

Are you using a PAC (Proxy Auto-Config) file for Internet access? I'm guessing that this works for other browsers like Google Chrome and IE...

I had a similar situation at work whereby the PAC file would not provide Internet access in Firefox, but setting the proxy to the manual IP address worked. Ideally we wanted the PAC file to work in all browsers, so this was the fix:

IPv6

Firefox supports IPv6 by default, which may cause connection problems on certain systems. To disable IPv6 in Firefox:

1. In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.

2. In the Search field, type network.dns.disableIPv6.

3. In the list of preferences, double-click network.dns.disableIPv6 to set its value to true.

4. Close and restart Firefox to test.

Hopefully this solves your issue!

Also check here to see if SSL is enabled in Firefox:

http://support.mozilla.org/en-US/kb/Firefox%20cannot%20connect%20securely%20because%20the%20SSL%20protocol%20is%20disabled

There is a link at the bottom of the webpage above to test SSL connections in Firefox; see below:

Do you have SSL connections configured to go out via your proxy in Firefox also? > http://superuser.com/questions/254481/unable-to-open-any-https-site-using-firefox

This website seems to have a lot of good information on this issue, but you didn't mention any errors being reported; if any:

    • Google Chrome is killing all uBlock Origin bypasses, Microsoft Edge, Opera to follow

      Braves ad blocking shields are their own implementation separate from extensions. It won't have any issue continuing to work.

      Same for me. I find Adguard in general just OK. Ublock Orgin Lite works and works well. I use it on Chrome, Edge, and Safari on MacOS and iPadOS/iOS.

      I do not use the AdGuard extension. I have uninstalled both the uBlock and Stylus extensions, as well as the Tampermonkey extension, since I began using AdGuard for Windows 7 months ago. It does not use any extension APIs, it modifies traffic system wide using a local proxy. AdGuard performs all the functions of uBlock, as well as additional features such as HTTPS filtering, cosmetic (user scripts and user styles), as well as DNS. It works with any browser and application. I don't understand why you consider the desktop program to be useless...

      Should Google be forced to stop promoting Chrome over other browsers? Google pushes Chrome to anyone visiting its website using browsers other than Chrome.
    • Save 31% on Samsung T7 Portable SSD

      Save 31% on Samsung T7 Portable SSD by Taras Buria During the ongoing memory crisis, where RAM and storage get extremely expensive, it is hard to find a good deal on an internal or portable SSD. While we are far away from 2024 prices, Samsung is currently offering a big discount on its 1TB T7 Portable SSD, saving you 31% or $85. The discount applies to the 1TB variant, which, although not record-breaking, is still plenty for all sorts of data. The drive uses a USB-C port for universal compatibility and high-speed data transfer of up to 1,050 megabytes per second. Samsung claims this drive is nearly ten times faster than a conventional hard drive, plus you get all the benefits of solid-state memory, such as better drop and shock resistance. There is also the ability to password-protect the drive, and you get extra peace of mind with a limited three-year warranty. The Samsung T7 Portable SSD works with all modern computers and tablets, including iPhones, iPads, Android smartphones, and more. And thanks to the two bundled USB cables (Type-C and Type-A), you can use the T7 even with devices that lack USB Type-C ports. The T7 Portable is available in three colors and four storage configurations, but unfortunately, only the 1TB Titan Gray is discounted: 1TB Samsung T7 Portable SSD - $189.98 | 31% off on Amazon This Amazon deal is US-specific and not available in other regions unless specified.
