Firefox Community Forum

When ever I try to login to my bank I get a black page with this in the left hand corner. I can not logon. 'type "about:blank" title "Bad Request" status 400 detail "Failed to convert 'userIdEncrypted' with value: " instance "/dias/authenticate"

I get this when trying to link to a site from my emails, but only on some. Hmm. We’re having trouble finding that site.

We can’t connect to the server at oblmlwbab.cc.rs6.net.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

Hello, FireFox keep blocking access to one of my Websites. I am getting this message: Can you please help?

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to account.apps.progressive.com because this website requires a secure connection.

What can you do about it?

account.apps.progressive.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.

Probably nothing, since it’s likely there’s a problem with the site itself.

For two days I have been unable to access the internet using my default Mozilla Firefox browser. I have used Mozilla as my default browser for many years with no problems, but have had to use alternative browsers not only to access my emails on Outlook, as well as other nominal sites, but even to sign into my Mozilla account, I had to use Microsoft Edge browser. I have made no changes to my settings or internet security. Please advise. Thankyou

https://read.amazon.com/kindle-library is now not allowing me to go onto the website. I've tried talking to Amazon customer support but they can't find a problem on their end. It says:

The connection has timed out

The server at read.amazon.com is taking too long to respond.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

I haven't had a problem with the website before and every other website I have tried works fine. It's just that one. I have added it to my exceptions list for add ons but it didn't fix it.

Hi all, trying to configure autoupdate settings for my org, as we're discovering several out of date installations.

One sticking point I'm seeing is that I see conflicting documentation on the required proxy setting for background updates to work.

This page states that the correct proxy setting is to use system settings https://support.mozilla.org/en-US/kb/enable-background-updates-firefox-windows

Meanwhile, this page states that proxy settings must not be configured. https://firefox-source-docs.mozilla.org/toolkit/mozapps/update/docs/BackgroundUpdates.html

Which one is authoritative?

as an aside, some of the required prefs cited in the second document don't appear in about:config on the current version. I do see app.update.background.allowUpdatesForUnelevatedInstallations and app.update.auto.migrated which I'm assuming for the moment are the correct prefs, but can that be confirmed?

I just purchased a year subscription for the Mozilla VPN. I want to be able to verify that the FireFox browser I'm using is accessing the web via the VPN. How do I verify that? I don't see any icon indicated that it's a VPN connection.

I CANNOT get on to Archive of Our own, all firefox does is tell me "Secure Connection Failed" and display an error page. I have done everything, I have cleared my cache I have tried disabling security things and add ons I have tried the "about:config" thing MULTIPLE TIMES. It's only happening on my computer not on my phone PLEASE someone fix this I just want to update my fanfics I don't know why this is happening it's only been going on for about a week and it is UNBEARABLE.

For the past few weeks Firefox has been crashing and freezing often. Crashes are worst when trying to access Protonmail, which almost always crashes the tab instantly. Freezes happen most often when browsing Reddit, and also when watching Youtube, but crashes and freezes can happen on almost any website.

I have tried changing profiles, refreshing and uninstalling/reinstalling, but the problem persists and seems to be getting worse over time.

Here are some recent crash reports:
