I found that when starting Firefox on my school's WiFi, it starts up very slowly. Using `strace`, I found that it was taking it's sweet time making a DNS request to try to resolve my computer's `/etc/hostname`. After searching the Firefox source code with https://searchfox.org/mozilla-central/source/, I found that the only occurrence of `/etc/hostname` was in [SandboxTestingChildTests.h](https://searchfox.org/mozilla-central/source/security/sandbox/common/test/SandboxTestingChildTests.h). So I was wondering if it's possible to disable these tests when Firefox starts up.

Hi! Yes I've seen and tried the advise on https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20 and also tried thunderbirds debug mode but still: on every start Thb ist asking me in several windows for the google user name and password BUT: the gmail-account and the cardbook extension is working fine. It's just that annoying question (I simply hit escape on it). Kind regards, Markus

Ref Firefox Ver 84.0.1 OS > Win 7-64 Dear Firefox Support,

 I have already contacted MS support about the subject issue and they were no help.

I am trying to find out what is causing the issue and how to get rid of it.

 I can't be sure but it may be caused by a Microsoft "START" App.  The issue appeared

to begin about two weeks ago, so it's obviously caused by something new, which may be Microsoft related. Below is Dropbox link to a screen capture of the issue.

 Any tips for ridding my PC / Firefox browser of the issue will be greatly appreciated.
 And thank you for the superb browser.

Best regards, Ken Boardman > elsmoko@cox.net

Hey. I have countless issues with Thunderbird, but two I need to solve now:

1. TB doesn't respect setting called "Sync last x days of emails" and sync everything. That causes it to consume lot of resources and my PC is very slow and fan has to run full blast. 2. I have changed login info on my CalDAV calendar so I wanted to remove the old ones and add the new one. However the old one wasn't somehow properly removed from my Ubuntu online accounts and TB keeps ghosting me to enter login info of account that doesn't exist anymore.

Version: latest Platform: Ubuntu 22.04

I'm experiencing a strange problem with this Google review-link for my customer:

After the login-procedure for Google I end up with a 404-Error and can't find any help at Google. I also wonder where that local URL is coming from.

It works on iOS and on Chrome or Samsung Internet on Android. Here's the error message: The requested URL /local/writereview?placeid=ChIJazm4u47ql0cRsiGgJDKAtQ8&source=g.page.m.ia._&laa=nmx-review-solicitation-ia2 was not found on this server. That’s all we know.

I already tried to disable safe browsing and cleared my cache. Nothing helps. Looks like a bug.

After update thunderbird sending errors in all accounts. Removng all data (profile and cache folders) and reconfigure not help. Use:

• Xubuntu 22.04
• snap install
• version 102.9.0 (64-bit)

Hello, I am a long time user of Thunderbird and appreciate all the work that is going on to update the software. My simple piece of feedback, purely for your information, is that connecting to the Thunderbird and collecting messages has now become very slow. In the past the process was almost instant, not so now. I am sure that you are aware of this but if not I hope this is useful to you. Keep up the great work. Thank you. Gerry Bird.

i installed the latest version from the website, and it only opens for a split second before it crashes. no error message, it just closes before its even fully open. same thing in troubleshoot mode: the troubleshoot mode popup only appears for a second, i dont even have time to read it before it closes. no error message. i tried a clean reinstall and nothing changed. i opened it in safe mode and it worked with no problems. i read that there are sometimes issues with avast, which i used to have, so i deleted the residual files i found in AppData and Program Files. still nothing. now the only antivirus/firewall software i have is windows defender (and i know that because windows defender keeps telling me haha), and i tried adjusting the windows firewall- still nothing. i would love to include a crash report ID, but there are no crash reports in the folder (photo attached), even though ive tried to open the app half a dozen times since reinstalling.

not sure if its relevant, but just in case- when i couldnt open the version from the website, i tried installing it from the microsoft store, and it actually worked fine at first. but shortly after i finished setting it up (it was probably open for less than an hour), it crashed and then it was the same- crashing immediately upon startup. i have since uninstalled it, in case they were interacting in a weird way, so now i only have the version from the website. i also have the mobile app on my phone and it works like a charm.

i consider myself pretty good at troubleshooting, but im completely stumped here. sorry for the long post, any guidance would be greatly appreciated

When I try to open "www.metservice.com" Firefox freezes completely. This did not use to happen and does not on Chrome. I have to restart my laptop to fix the freeze!! As it is a site I use regularly it is somewhat of a nuisance.

I turned on my desktop Mac today after five weeks away. All the folders in my main email inbox on Thunderbird have disappeared and, when I try to send an email I get the following error message: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

I checked the setting with Thunderbird on my Macbook and there is not problem: all the folders are still there and the server settings are identical on both computers. In addition, I'm not getting any emails in that inbox on my desktop Mac, though on my Macbook they are all coming through fine..

Also, I have several other email inboxes on my Thunderbird and they are all working just fine on my desktop Mac. It's just that one email box on that one computer.

Any solutions, anyone`/

I tried using troubleshoot mode and the crashes happened on there too. I uninstalled and reinstalled firefox, created a new account, removed and added my extensions back on, restarted my computer, and yet the issue keeps persisting. The browser doesn't prompt me to send in a crash report when this happens either, it's only the tabs not the browser itself that repeatedly crashes.

Since the last update various programs we try to play on ITVX.com hang Firefox. Again tonight we ended up having to switch to chrome which behaves ok. End up having to crash FF from Task Manager.

I have a Mac running Ventura 13.2.1 I use Thunderbird 102.9.0. When I try to retrieve mail, it takes over a minute. The bottom of the screen says "Host contacted Sending Login Information".

I am running no anti virus programs and have none on my computer

Windows11 Firefox 111.0.1 (64 bit) intermittently stops loading page while scrolling. Won't refresh or go back to previous page. No error message. Have to restart Firefox.

T'bird & Firfox, Win 11 OS. Prob: one weekly formatted newsletter has for over one month come in as an unformatted monster para.
