I am writing to report a recurring technical issue that began appearing today across multiple devices.

When attempting to access Google websites (specifically Gmail and Google News) using the Firefox browser, users are being prompted to identify themselves via a security certificate. Previously, this authentication step did not occur, and access was seamless.

Key Observations:

Impact: We have confirmed this behavior on three firm-issued computers as well as one personal device.

Browser: The issue is isolated to Firefox; other browsers appear unaffected.

Timing: This behavior was not present yesterday; it started manifesting today.

We suspect this may be related to a recent network configuration change, a new security policy rollout, or a browser update that has altered how Firefox handles trusted connections to Google services.

Could you please inform me whether there have been any recent changes to our SSL inspection proxies, root certificate stores, or DNS configurations? Additionally, does anyone else on the team have visibility into a widespread incident affecting Google certificates, or should we proceed with troubleshooting individual profiles?

One Win 10 laptop has Firefox 151.0.4 64bit and I've got the Firefox VPN working on it. My other Win 10 laptop has Firefox 152.0 32bit for some reason, and I've logged on Mozilla but all I can find in VPN requires payment. I don't understand the diff that the higher version is 32bit and I can't find the FREE VPN . What should I do?

I had a great Thunderbird Emoji add-on that is no longer supported. This.

https://services.addons.thunderbird.net/en-US/thunderbird/addon/emojiaddin/

It no longer works on updated Thunderbird, and shows it hasn't been updated since 2022. I'm on Thunderbird 140.11 on my Linux Mint. The image the plugin inserts in message bodies is broken. Is there another/similar add-on?

I have always, for 15+ years, been able to use the system Print dialog box to create a PDF.

But as of updating Firefox to version 152.0 (aarch64), all buttons related to Saving a PDF, etc. send the document straight to the Printer to print a hard copy. There no longer appears to be any way to save a PDF.

Example scenario: 1.) Visit website 2.) Select Print (cmd-P, File > Print) and open the 1st print dialog box 3.) Select "Print using the system dialog..." 4.) Select PDF in the 2nd dialog box. 5.) You used to be able to save the PDF at this stage, opening Finder, naming the file, and choose the Save DIR. However, as of this latest update, even after the Finder File Name dialog box, hitting Save at that stage sends it to the printer to print a hard copy.

Pressing PDF, Save as PDF, Open in Preview, and Save as Adobe PDF all send the file directly to the Printer to save it.

I've got tons of receipts and things to save for work in PDF and FF was always great at this. What happened? Is this a feature or a bug? Any and all advice is welcomed.

I have downloaded "Free Stock Ticker" and please tell me how install it on "Startpage" which is my home browser on Firefox. I do not know how to install download programs.

Enhanced Tracking Protection is stopping me from accessing many websites which, on other browsers including Firefox for Android, have nothing wrong with them - UK Met Office, forums, webcomics, Patreon... In many places, it's stopping me from connecting to the website altogether, or even logging into desktop app services when I have to use a browser link to log in; the login process simply doesn't resolve. I've tried disabling and removing extensions, changing settings, refreshing the browser and clearing the startup cache, but nothing seems to help. I cannot work out what's wrong, and I cannot disable Enhanced Tracking Protection. I'm having to send this message via TOR browser, because on Firefox, the Mozilla Support site is reduced to just text and links, with no frames or images, and barely navigable. This also means I can't pull Troubleshooting data direct from my Firefox browser for this form, because the form page's display is also broken on Firefox; I may be able to provide troubleshooting data on request, but I will require step-by-step guidance.

I don't know what to do, and I need help.

Please ask Thunderbird to stop making a tab on my taskbar every time I open an email. I have to close each one individually, and I never asked for these to be shown, and I don't need them shown. This is a tedious extra chore. I already have access to emails that I receive in my in box. It shows the history. I don't need any other index to them. Do you know how to stop making any other such tab or index? If not, please pass this on, and please don't say that you can't pass on this request. Someone decided to make these tabs show up on my screen and task bar, and to require me to close them by clicking on each little red X mark. I should be able to make contact with whoever makes these decisions and writes these programs, and to provide feedback and suggestions to them.

When I initialize Firefox, before being promoted for the profile, bing opens the browser tab. Bing is not my default search engine. Why is it on Firefox? I don't use Bing.

I chose passwords and sign in, but there's more. You are already aware of the Facebook issues but there are others issues with this and I personally don't have time to tell you how to do your job. I have to keep up my production to keep my job. Your browser really cost me labor time. So, I would like to know do you recommend going back to a previous version until you fix this mess? OR... what ohter browser would you recommend as your replacement?

I appreciate your time, and I look forward to your answer.

Thank you R

Over the past week or so, I've been finding that Youtube videos don't start from the very beginning - the very opening is missing.

So as examples, you're playing a song that you know starts directly on a beat, but that first beat gets missed, or there will be an opening sentence such as "Everybody is talking about the latest... " and what you hear is more like "Vrybody" - you can clearly hear that It's slightly off.

This relates to Firefox in three ways.

My initial thought was that there is some conflict with using an Adblocker (uBlock in my case) as Youtube is trying to force a pre-video ad that won't play, but even with the adblocker disabled the problem persists.

I then cleared my Firefox Youtube history so it loads as a completely fresh version - but the problem is still there.

Finally, I tried the same video on Chrome to see if this is definitely a Youtube issue...and it plays correctly without a problem.

Therefore, the problem seems confined to Firefox but I am unsure where - what setting needs to get tweaked to sort this out?

A category (Daily Brain something) of emails that are clearly spam (you even think they are spam) are landing in my Inbox every day. I have my email set to not allow emails from any addresses that aren't in my book. If I follow their 'unsubscribe' link, I just get more of them. This is the latest one: ar849137@ocotille.com with a Reply To address of: 3527_rep_Y2pnZGVzaWduc0BlYXJ0aGxpbmsubmV0@ocotille.com Every one is different. Why are these getting through? Thanks Cary

Lost all tabs during an update including(weirdly) all theme stuff. Its not in the restore in history. But the themes part is the one that is strange, because why would themes change during an update, all while all my tabs are lost?
