Firefox just updated to 152 this evening on my Windows 11 Pro system. It seems slow compared to prior versions. Also , every time you log out , it crashes and activates crashreporter which files the report. Any clues? Nothing changed on the system except for Firefox.

The sent message is deleted but I get Filter action Failed.

We are managing Firefox settings using Intune via Imported ADMX templates.

We are managing Extension Settings via 'Extension Management (JSON on one line)' which works fine for our force installs, force removals etc.

We have noticed that some users have installed 3rd party extensions which create the ExtensionSettings key in the registry with the 3rd party extension details.

The issue we see if when ExtensionSettings exists as a REG_SZ or REG_MULTI_SZ under `HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox` it is then ignored if the `HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\ExtensionSettings` key exists.

Is there a setting we can use to have these settings merged by Firefox or have the REG_SZ/REG_MULTI_SZ take priority or is the only way to ensure enterprise policy continues to work we need to migrate our extension settings into the key rather than string?

Thanks!

Hello, for some time now I've been experiencing a number of problems with the latest Firefox updates.

Today I have version 152.0 (64-bit), which was updated again this morning. I restarted my mid-2015 MacBook Pro Retina. I have fiber optic internet, which is very high speed.

I've been using Firefox for over two years.

1) For the past eight days, I've been experiencing many problems with Google Meet; I get freezes, audio and video dropouts...

2) For the past three days, I haven't been able to log in to this website: https://creators.spotify.com/pod/login

3) For about ten days, I've been having trouble logging into my Stripe dashboard, with significant slowness and/or crashes.

4) In Notion, I'm also experiencing significant slowness, with pages taking a long time to load.

In short, several problems that I didn't have at all a month ago or before.

But now it's a nightmare.

I don't have any of these problems in Safari or Google Chrome.

So what's going on in Firefox?

Why is it such a hassle?

Thanks for your feedback.

Hi everyone,

Since the Firefox Developer Edition update 152.0beta, saving as a PDF via the print menu no longer works. Although the “Save as PDF” option is available and selected by me, the job is always sent to the laser printer (which is not supposed to print it, of course). This happens on every conceivable website, so the website itself is not the cause. (Platform: macOS Tahoe 26.5.1)

For years, generating PDFs via the print menu has worked flawlessly with FF—now I’m forced to take a detour via Safari, for example—which works correctly in the long run—but isn’t my preferred solution. I don’t think you need different browsers just to use “normal” functions. So who has recently tinkered with this FF feature?

Since I can’t find the relevant setting in the FF preferences—and a “search” on this topic has been unsuccessful—I’d like to know if there’s a solution?

Best regards, HS

hello, i had a friend and his father needed urgently to migrate his thunderbird with 1 email to a new computer but he wasnt able to setup the emailaccount in a new german client. i helped and the problem was that the setup asks for the password but it meant the password from the emailprovider to allow thirdpartyapps access. please consider to improve the german setup wizard by adding a new textline to clearify. best regards

Tabs will crash over and over again. I can barely look at any given page for longer than a minute or two. What happened?? Firefox was never like this before. It just crashed in the middle of me typing this LMAO. Using Brave in the meantime. This is ridiculous.

Firefox has just updated on my Windows 11 PC at around 1100 17/06/2026 and now I cannot access my Spanish banking online with Banco Sabadell.

When I try to log in I get a message saying 'the process cannot proceed because of security issues.'

I could log in prior to the update and I can still log in using Brave.

By process of elimination I deduced that it must be something to do with the update.

I have a Yahoo.ca email address and have been using Thunderbird to retrieve my email for years. For some reason, a window now pops up to Rogers.com and they want me to log in there. This is not a Rogers email address and it is separate from Rogers. I had this issue before and this forum managed to get me back. My settings are correct. I have deleted the profile 5 times and added it back after a computer restart and still nothing.

Hello, from time to time my Thunderbird on my desktop PC running windows 10 doesn't receive emails, while they arrived on my I Phone 8. Checked my Telstra web mail, all emails are there so what is stopping getting to my desktop PC? I thought the Thunderbird receives emails than synchronize with my I Phone? As you can see from my 2 images the Telstra is up to today as is my I phone But Thunderbird is 3 days beyond. Tomorrow it may back to normal or the next day? I am returning to this message the next day 16/06/2026 1 more message on my I Phone, still nothing on my Thunderbird.

An other problem I get with Thunderbird is that a message appears on the right bottom of my screen: "Mozilla Thunderbird Connection to server mail.bigpond.com timed out" and/or "failed to connect to mail server imap.telstra.com" If I try to send an email after the above notifications, I get the "Connection Refused". I know than to just walk away. I am using Starlink as Telstra here doesn't work as I am on the fringes of Melbourne in a BLACK HOLE. Any help will be gratefully received. Thank you for reading this.
