Firefox Support Forum

I'm working on a website for a client and all of a sudden I can't load any single page on that site only. I was just logged into to the dashboard and making changes. Now I can't even load a page.

The error is a cgi-sys/suspendedpage.cgi for any page I attempt to load. This is also happening on chrome on the same desktop computer.

I can load and login to the dashboard on both my phone and my laptop on the same wireless network without issue. I tried everything I know how. Cleared the cache and history, flushed the dns, reinstalled firefox, etc and this error will simply not go away.

At one point it was saying the security certificate was expired (it's not) and tried to add an exception but that didn't work either. Back to the cgi-sys/suspendedpage.cgi

I'm out of ideas and totally frustrated. Please help!!! lol

I am getting a TLS error on Firefox 82.0.3 (64bit) - Win 10 Pro 64 bit Followed instructions on https://support.mozilla.org/en-US/kb/how-disable-enterprise-roots-preference "security.certerrors.mitm.auto_enable_enterprise_roots" is set to disabled but "security.enterprise_roots.enabled" is set to true but is greyed out and I do not have a toggle option to disable it - why and what is the solution ?

Hi Everyone,

I run Windows 7 Ultimate SP1 and Firefox version 72.0.2, with DuckDuckGo Privacy Essentials and search engine, and New Tab version 1 by Leigh Brenecki.

All works well, other than, having opened Firefox with the first "Tab" available, when I click the "+" sign for a New Tab, the error message "Blocked by Content Security Policy" and "An error occurred during a connection to duckduckgo.com" is displayed.

However, if I click on the Firefox Home Page "House" icon, or select any of my Bookmarks Toolbar icons, the message goes away and all works well again -- at least until I try opening another New Tab when the cycle starts again.

I realise this might be a "New Tab" or "DuckDuckGo" problem, and will seek their support accordingly - I just wondered if anyone on here had experienced the same?

Thank you,

Ian

Getting error SSL_ERROR_BAD_CERT_DOMAIN on all my sites that are signed with a SSL Cert from my internal CA since updating past version 99

This appears to be a bug starting after Firefox version 99 on Windows because after i upgraded to Firefox version 100 i started getting this on all my SSL Certs from my CA and they worked fine prior to the update. Can anyone confirm if something changed after version 100 that is causing this?

Thank you.

When I attempt to access several websites, I am prompted to turn off my ad blocker. As I have not added a third-party software or extension that does such, I assume it is part of Firefox proper. Search as I might, I cannot find any specific reference to such a thing in "Settings". SO...how can I temporarily disable the 'Ad Blocker' device that is part of Firefox? The 'TEMPORARY' part is important, as I do greatly value the function!

I'm running Linux Mint 20 and have installed a free version of ProtonVPN. My firefox browser has a banner at the top stating "Your Browser is Being Managed by Your Organization". Not sure how this happened, but I am unable to update the browser because of this. I read some of the previous posts and they all appear to reference a Microsoft OS and Avast.

Using Firefox 68.12.0ESR. I know 78 is available, I just haven't had the time to test it yet. I delete cookies when I exit Firefox. I want to keep some for sites that I trust, such as this site. I've added exceptions to Allow these trusted sites as documented on a thread somewhere else, but it doesn't work. All cookies are deleted.

Is it possible to keep cookies only for a select group of sites. eg. support.mozilla.com, tomshardware.com, mydigitallife.net, speedtest.net and so on.

Thank you.

Hello, After upgrade FF ESR 68 -> ESR 78 i lost the possibility to connect to HSTS enabled websites (tested on duckduckgo.com and my nextcloud) on work network.

Work network issue intermediate certificate and with FF 78 i am forced to install that zscaler certificate to make website work, I cannot accept that certificate temporarely.

How to reenable possibility to add exceprion for hsts enabled websites?

Windows 7 Firefox ESR 78 Portable.

For now I downgraded to FF 68.

I have Firefox 84.0.1 on Linux Mint, and I have filled in the information for one credit card. When I hover over credit card fields on retail site forms, I usually (but not always) get a pop-up "hint" showing the card number and/or expiration date ... but I cannot get the browser to actually fill in the form field. I've tried clicking, hitting Enter, hitting Tab, but nothing actually puts the information from the pop-up into the form field. Any hints as to what part of the incantation I am missing would be appreciated.

Hello.

backed up an Ubuntu repository version of Mozilla firefox that was working and then did a new install of firefox from Mozilla repository.

Migrated bookmarks. Followed instructions to migrate passwords - copy over key4.db and logins.json to new install - but the new install does not prompt for passwords and when I look at the settings there are no saved passwords showing.

What's the preferred method to move over auto logins and passwords?

I have a few add-ons installed in Firefox (85.0.1, 64-bit, under Windows 10, 1909), but when I open a Private Browsing window, I can no longer access them. True, they are still there and can be seen listed under Menu/Add-ons, but I don't see how to control them there, only enable or disable them.

If I want to use NoScript (for example) in a Private Browsing window, how do I set Firefox up to do that? -- jclarkw

How do you access Mozilla VPN after you have logged into firefox account - it only shows how to download and I have already downloaded it. I simply want to turn on the VPN and select the location but no instructions are available for this or at least the instructions are not clear.

Right now, I'm logged in my Firefox account and have everything backed up (logins and passwords, bookmarks, history, etc). Thing is, I do not remember my Firefox account password, but thankfully I am logged in and synced through 3 devices. I think, there may be a situation when some time in the future, I will be logged out one way or another.

Is there a way to see my Firefox account password, since changing password results in everything being deleted? I want to not get involved in such a hassle of exporting and importing data, if I can help it.

Thanks in advance.

The issue described here does not affect version 77.0.1 and earlier, only 78.0 and later.

Update: Wrote an complete analysis on this as HSTS for human beings HSTS for human beings

So, we have a number of internal sites employing a self-signed certificate with a CN not matching the hostname. As an example of such devices are HP iLOs, switches and a series of others that are now completely inaccebile through Firefox.

Up until version 77.0.1, we were getting the usual notofication about the two issues (not trusted and cn is wrong) but we could Add an exception and proceed.

After updating to version 78.0, proceeding is not offered as an option, due to HSTS requirments.

hostname.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

Troubleshooting done already; Completely deleted everything (FF and profiles and start clean - same issue Renamed SiteSecurityServiceState.txt so FF can create a new one - same issue Imported the certificate into Firefox as an exception manually as per images attached - same issue

At this point, there is no way to access those sites no matter what we have done and the issue persists up to the latest current version of the browser.

Just as a hint, the same issue appeared the same period of time (during the summer) on Chrome and Chromium Edge.

• Desired behavior: I can add my own trusted Certificate Authority next to all the others.
• Actual behavior: After clicking “Import” and selecting the root CA's cert file, reloading the website it certifies still yields an Unknown Issuer error.

I am running Firefox 80.0 on Fedora Linux 32.

This certificate file works perfectly fine on another browser.

After watching this video https://www.youtube.com/watch?v=mAfY_bNJTBI i went to https://www.cloudflare.com/ssl/encrypted-sni/ and did the test. Result is 3/4. (See screenshot below) Secure DNS, check DNSSEC, check TLS 1.3 check Enrypted SNI, fail In Firefox i tried doing exactly what the person did in the video but i dont have the settings he is showing in about:config Why is that? (Below you can see the screenshot, those settings are missing from about:config)

So my question reamins simple, how can i enable Enrypted SNI in Firefox?
