Hello,

I’ve been having a performance problem with Firefox that only happens when I play the Letter Boxed web game from the New York Times.

When I open the puzzle in Firefox (latest version), the letters load fine, but as soon as I start typing, the browser becomes laggy input delays, slow animations, and occasionally the whole tab freezes for a few seconds. I’ve tried the following, but none have fixed it:

Restarting Firefox Disabling all add-ons Clearing cache and cookies Updating Firefox to the latest version Running in Safe Mode

Other websites and games work normally, and the issue only appears with this specific NYT game. It also doesn’t happen in other browsers on the same machine.

System Info: ‑ OS: Windows 10 ‑ Firefox Version: (latest stable) ‑ RAM: 16 GB ‑ CPU: Intel i5

Questions:

Is this a known issue with Firefox and the Letter Boxed game? Are there specific settings (hardware acceleration, graphics) that I should adjust? How can I troubleshoot what is causing the lag within Firefox?

Any help would be greatly appreciated thanks in advance!

I love Firefox and have used it forever. But its memory usage is killing me lately and I'm seriously reconsidering.... PC, Win11, Intel7, 16GB memory. (I'm typing this from Chrome)

I've updated, restarted, but it keeps maxing out and slowing my computer to a crawl. Somebody please tell me there's a fix pending?

I have saved relevant e mails to local folders in my Thunderbird account on my Applemac. I opened up Thunderbird on my MacBook and downloaded my Thunderbird account but it did not copy those local folders, merely 1 empty folder. Without these also shown in my Thunderbird account when I am away from home, I cannot see those records. I am struggling to find a solution. Are you able to help please? Alan Dowler

I was on a website for Met Opera, buying tickets and suddenly a widget appeared on the lower left corner that says: Opt-Out Signal Honored. Not only did I Opt Out, but I no longer can navigate the website, and there is no visible way to cancel this. Please help. It does not appeaer on other web pages, or other browsers. What is this? I've tried locating it in settings, and settings does not have that privacy option checked. How can I remove it? thank you, Anne Marie Mascia

Firefox 148.0.2

Hi,

I have set up a Mozilla ID and followed the instructions to see if Firefox will let me set up its new VPN - as I am based in the UK, I thought I would be eligible. Having logged onto Mozilla, I cannot see any VPN-related things in Firefox and I cannot restart Firefox as this will log me out of Mozilla.

When will this option be available to commoners like me?

Thanks

I've tried Troubleshoot mode, everything I can seed for filtering options. I still see the folder has 12 messages in it but the window always shows No messages found.

No topic listing above for this Thunderbird Calendar issue. Calendar events disappear completely. I have been scheduling series events using the weekly repeat. Then modifying the few that change. Somewhere the whole series just disappears. Example: PT-Kathleen was input as Monday at 11 to remind 3 day's in advance and repeat for three months. Then I modified several that were scheduled differently. All is good for several weeks then 1 the reminders no longer work. Then the whole series disappears. This has happened for about five of these series and I just put all the stuff back in. But, then that disappears also. Any thoughts things I should setup differently?? tired of redoing things multiple times. Robert Kelly

When I enable the firefox built-in vpn I have an error: "The proxy server is not found

Firefox cannot connect to the server at accounts.firefox.com What can you do?

Try to connect to another device. Check your modem or router. Log out and reconnect to Wi-Fi."

Thanks.

I use Firefox as it is one of the last good browsers that isn't chromium based. However, I use it for work and like a nice clean PROFESSIONAL look.

With the introduction of version 149, I see new cartoonish fox icons pop up all over the place. After a little research it appears to be Kit, the firefox mascot.

Let me be clear, I don't hate the mascot, he's cute. But that is not what I want in a browser. I find his appearance and lack of ability to eliminate him infuriating.

I try to run a firefox in a as minimalistic state as possible. Intruducutions of this character, make the browser feel cartoony and childish. Things I despise in an application. I know many people like him, but I would like the option to not have him appear in the application at all.

I was able to successfully remove him from the certificate warning page setting the flag: security.certerrors.felt-privacy-v1 --> FALSE.

However, I can't find other places to remove this nuisance. Take a look at the attached screenshot. Things like this are not welcome without a way to disable it.

Do you have any documentation or instructions I can use to disable this childish nonsense and restore an adult browser again?

Hi,

Can you please have a look at the following problem: I decided to re-index my mails. after I realized that the search results did structurally not contain any messages from 2026. I deleted the global-messages-db.sqlite. However, this did not lead to the desired result. After processing some folders, I can see in Activity Manager that the indexing stands still after having processed about 20% of the "Sent Mail" folder of a gmail account. I waited more than 12 hours, but the number of indexed messages did not increase. The file size of the global-messages-db.sqlite at this moment is only 2.3 KB, while the original database was more that 300 MB large.

I already tried the following without success:

1. restarted TB
2. deleted the database for the second time
3. restarted my PC
4. repaired said "Sent Mail" folder

I am running Thunderbird 140.9.0esr on Windows 11.

Many thanks in advance for your replies.

In Thunderbird, how can I stop text in the previous emails in a string turning blue?

I have looked everywhere in Settings where colour is mentioned and everything is set to black text on a white background. Nothing is set to blue.

I do not want to see blue text anywhere.

Please advise.

Good Day,

currently Mozilla Thunderbird does only show a short history header for email reply messages like, e.g.:

 *  "On 26.03.2026 at 21:41 John Dow wrote:  "

Why is that and can it be changed to a full history header message like on forwarded messages, e.g.:

• "-------- Forwarded Message --------

subject: 	Fwd: Subject of mail
Date: 	Tue, 10 Mar 2026 17:26:08 +0100
From: 	SenderMailAddress
To: 	ReceiverMailAddress

(CC: CarbonCopyMailAddresses)

  "

A full mail history header does often help to show more detailed information in mail history so I and propably many others would prefere this kind of full header information. It is also a Standard in Microsoft Outlook.

Please check.

Thanks in advance Klaus

I have successfully added my primary Google Workspace email address, authenticating through OAuth 2.0. I'm adding a second user, but even though I sign in using the Google popup, OAuth isn't listed as an Authentication method under Server Settings, and no email is downloaded.
