Firefox Community Forum

I've use Firefox vpn for some time now. Suddenly any attempt to access a website, including the lovely link to my kindle book suggested by Firefox results in this: Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem. message. Firefox is blocking me with no way around??? Regular firefox now just doesn't download! I want to congratulate your implementation of a security nightmare with zero testing. Please tell you product development and marketing folks that they won't have to worry our reading and acting on any of your advertisements!

When opening websites the images are not opening, only blank boxes appear. I don't have any settings for security causing problems because I turned them off previously. simply cannot find what is driving this. Thanks, Don

I'm using Firefox esr, the latest version 149.0.2. Since this update, I can no longer load the videos on NPR.org's home page. Something pops up, but then the wheel/circle thingie just goes round and round, and never loads the video.

My ad blocker was already off for this site. I've tried restarting Firefox in Troubleshooting mode, and changing the various security settings mentioned in this article: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings, such as adding it to the "Allow popups" exceptions (never necessary before) and other settings. I've reloaded the page multiple times, restarted Firefox, etc.

Can anyone suggest anything else to try?

Relevant to Firefox running on Ubuntu 22.04 Linux and an x86_64 platform.

Until roughly 2/2026, it was possible to load a security device by opening Settings, Privacy and Security, Security Devices, then browsing to a shared pkcs11 shared library, in my case /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so, and clicking Load. The shared library would load and would be loaded subsequently whenever Firefox was started. For roughly the last two months, Firefox would pop up an error saying it was not possible to load the security device, but it would actually be loaded and it;s functionality would be available for the current session. For the last two weeks, the library would load without error, but only for the current session. Starting on 4/13/2026, some functions in opensc-pkcs11.so work, but not others. For example, it is no longer possible to connect to MS Teams web interface.

Google Search CAPTCHA persists unless you sign in to your Google account. This only happens in your browser, from versions 140 to 149. Other browsers don't have this problem. Changing the user agent used to help. Now, nothing works.

I Loged In To My Firefox Account Today Done My Work and Close the Browser and Shutdown The Computer. On next Day When Again I On My Computer And Open Firefox The Firefox Account Gets Logged Out. I Am Facing This Issue From Long Time. I Want It Shoud Be Logged In and Only Loged Out When I Do. Plese Help Me Out.

I just lost my bookmarks again, it happened a month or so ago as well. Appears to have been due to updates.

I have already followed the recommended ideas of navigating to restore, but there is no date given to restore to.

Just "choose a file comes" up, and that appears to lead nowhere.

I also went about:profiles , and all that was there was the current "cannot be deleted " profile and the option to make a new one, I tried that, it did not restore bookmarks. I need some of tose bookmarks quite badly this time

What more can I do ?

First off - love Mozilla's work, thank you all for your efforts!

The problem: I f'd up with the Profiles option. I wanted to set up a Work profile on a new windows laptop associated with a new work email (msta....), and then separately have my personal profile connected to my gmail (mstn...).

Well somehow I managed to make my Work (default) profile connected to my overall Firefox + Google personal profile, and have spent a month in my ignorance saving away settings and bookmarks on this machine. Is there anyway that I can disconnect my Gmail account from the profile Work, and connect it to the secondary profile on the same machine titled 'Mel'? Or will I need to export the last month of bookmarks, implode my Mozilla install on this machine, and start over with new profiles and better practices?

Help, multipass!

Thanks, Mel

I face an issue with the browser crashing when in google meeting (meet.google.com). The problem persist in a new profile created with 'firefox.exe -P' and also in the troubleshooting mode. The crash is triggered when I am in the google meeting (with allowed microphone) and I manipulate with windows of the browser - across multiple monitors (switching tabs, moving tabs between windows, closing firefox windows, opening them, "dropping" the tabs onto another applications - chrome, spotify - which opens a new firefox window). Sometime the crash happened once I closed the google meeting tab. Unfortunately it happens "randomly" and I was not able to come with a specific series of steps to reproduce the crash. But it happens always when I am in the meeting and play with the windows for a while.

The crash: Firefox freezes for a few seconds (~3s) and then closes itself - all windows. %appdata%\Mozilla\Firefox\Crash Reports\pending contains a new .dmp file, but it has 0 bytes and no .extra file is created, hence it cannot be submitted via about:crashes. The crash reporter is not opened when firefox crashes. The attached troubleshooting information are from the new clear profile where the crash happens as well.
