I have never been a big fan of your products. However, i WAS curious about your email client, Thunderbird. So I decided to download it and try it out. THAT WAS A MISTAKE. I have a pretty good computer and have had vert little issues with other products from other companies. You products tend to freeze ALOT and I have spent the last 10 minutes attempting to enter my email information (e.g email and password) and keeps saying "UNABLE TO LOG IN AT SERVER, 'Probably wrong configuration username or password." I change the change the password and still nothing, so I manually entered protocol, hostname etc. and I am still getting same message. I check my firewall settings just be sure things were good. I checked with the my email and everything was ok there. What do wrong?

I've asked about this before but got no help Firefox is my browser of choice. Occasionally, I find in necessary to use Chrome.

The vast majority of time, when are both are active at the same time, one or both crash, like today. Firefox closed abruptly, then the crash report appeared. I have the crash report. Chrome froze up, and had to be shut down in Task Manager.

It only occurs in this scenario. Rarely does Firefox crash otherwise.

Can someone please advise where to go to get help?

Hello, I have uninstalled and reinstalled firefox twice using two different ways found on the community/mozilla website through chrome and I am still having trouble. It started a couple weeks ago when I received a notice at the top right hand of my firefox page for an update. I tried and it shows as Unable to connect. I tried various ways to connect with mozilla with no luck. I uninstalled, restarted my computer and reinstalled twice and still having the same issue. I lost all my plug ins and add ons after the reinstall and now I can't not even get them and can no longer sign into my firefox account through firefox. Anything that has to do with mozilla I can not reach unless I use chrome which I don't like doing. I have searched the community and nothing seems to help and I even submitted a help question in help community but no responders. Anything which I found addressing Unable to Connect was years old anyway. I can only assume it had to do with the update pop up which I never got to do and assumed a refresh or a reinstall would take care of it but it hasn't. What can I do? Thank You, Charyl

Got a new W11 computer and I know I've stopped it before.

I found https://support.mozilla.org/en-US/questions/1284577 on a search, but that didn't work and the answer is archived so I can't comment on it.

Where are the valid instructions?

Also, should I undo that? What other things might that now be doing?

I believe there is a memory leak (or memory growth) bug in Firefox 133.0 on Windows 10. It's site-specific. I am trying to login to my account at https://www.ssa.gov/, and it never actually gets to the login prompt. Using the Windows task manager, I can see the RAM usage keeps increasing, until it nears the 12 GB installed RAM capacity, at which time I kill the firefox process. I'd say this is a bug in ssa.gov, except the problem does not occur with the google chrome browser.

To provide further detail, I go to site https://www.ssa.gov/, and click on the "sign in" button. That takes me to the page where you choose the login method (id.me or login.gov) and I choose "id.me". It takes me to the "you are leaving Social Security's website " message, which is still on the ssa.gov website. At that point, firefox memory usage starts to increase, as shown in task manager. The browser never advances to the next page, but main memory usage keeps going up. This goes on for about 30 seconds before I have to kill the firefox process.

Od dwóch tygodni nie mogę wysłać wiadomości z żadnego konta email (mam 4 konta). Do tej pory wszystko działało, a używam Thunderbirda już 25 lat. Pozdrawiam, Janusz Kusztelak

Hi I started my Thunderbird on my laptop today 2024-11-26. However, last emails are from 2024-11-19, i.e 7 days ago.

I don't see what's wrong. No filters, strange sorting or similar are applied. When I login to same mailadress via webmail instead, everything works. There I have many mails between 19th Nov until today 26th Nov.

Any ideas what can be wrong? /Best Regards Joakim

Hi everyone,

I've been using Thunderbird for a few months now and never had any problems until today when I've updated to 128.5.0esr. I'm using iCloud email and suddenly my Sent folder disappeared. When I started TB it showed up and disappeared after 2-3 seconds. It happened few times when I tried to restart TB however now it's permanently gone. I didn't change any settings and the folder is visible in Apple Mail or Spark, however it's gone from TB. Any idea what's going on? Please help.

Thanks, Szymon.

What can I do to have Firefox be compatible with my emails. When I open an email for the local newspaper, the news paper is distorted and enlarged 200% and asks me to sign in. Everything was fine until the most recent Firefox update.

I want to remove the recent update which results in Firefox and some of my email links to be incompatible. The newspaper link works on Safari but I do most of my activity on Firefox.

Also, the email link works fine on Google Chrome. But I hate Google Chrome and don't want to use it. I would prefer that the Firefox browser be compatible with sites such as my local newspaper.

There a $21.40 charge on my CC statement for MZLA Thunderbird email. I had no idea who or what Thunderbird was until looking online. Found the website and saw Thunderbird is a "free" email app. My Verizon rep added it to my new iPhone 16 when it wouldn't send emails via my normal email provider (breezeline.net). I was not told the app was being installed, or that there is a fee for use it. He handed me back my phone and I saw a new gmail account had been added. What is the charge for? And why was I charged?

Hello, "desktop view" is very useful, and I use it for LinkedIn because the "mobile mode" is shitty (I guess to make/force people to install the proprietary and closed source LinkedIn app).

I found that "desktop view" is stopping working while activated, when you always keep a tab opened for days... I have to close the tab and open a new one to make "desktop view" working again.

I found too that "open in a new tab" action is not inheriting the view mode of the parent tab and that an issue when browsing the same website.

Could it be possible to have "desktop view" enable by default based on visited website?

Why do I keep getting pop-ups that 500% zoom in on the page with a message asking for me to clear cache? I have cleared my cache multiple times and restarted my computer many times as well, but it is still been a recurring problem for the past few days. It has been happening on every web page I visit, and even when there is no data to be cleared. Any information on how to fix this problem would be greatly appreciated, thank you.

I've noticed since a few upgraded of Firefox tat I am having an issue loading my local uTorrent GUI at: https://192.168.0.xxx:36724/gui/index.html. I am currently using 132.0.2 x64 and it eventually loads after 3-4 minutes. There are absolutely zero add-ons at the moment, and it does not matter if it is a portable version or standard installed version. I do not seem to have this issue while using Firefox (latest) ESR portable version.

Is there something I'm missing here? I am not sure if it is the port that's the issue with Firefox, because I have a local website using port 9090 and 8080 without any issues on loading. Also, it is happening with the nightly version of FF as well. All other browsers load quickly.

Kind regards,

Shedrock

I've encountered a bug in Mozilla Firefox where the browser becomes unresponsive when using Solid State Drives (SSDs), specifically PCI-E 3.0 SSDs with a 960GB M.2-110mm drive https://serverorbit.com/solid-state-drives-ssd/pci-e3-0-ssd/960gb-m-2-110mm. The issue seems to occur when multiple tabs are open, and the browser struggles to keep up with the data processing. Has anyone else experienced this issue, and are there any known fixes or workarounds?

Hello,

My setup is an old win7

2 days ago I got a power outage. When I turned my PC back on, thunderbird updated itself to 115.16.3 (32 bits) I am not sure which version it previously was.

Anyway, I have 4 profiles, the 3 profiles I was not connected on when the PC crashed are fine, totally unaffected. That should be a hint. My main profile was connected at the time, in fact I was writing an email when the crash occured. When back on I executed thunderbird I chose my main profil. I was immediately prompted with a 'welcome to thunderbird' asking me to input my credencials. I immediately closed TB scanned my disk for issues, checked my profiles folder which appeared to be fine. I indeed have a folder named hnych9cb.default in my %APPDATA%\Roaming\Thunderbird\Profiles which is was 2.2Go.

Then I had the (bad?) idea to input my credencials as asked thinking it might help TB to connect to the folders/emails inside my profile folder. I did but instead it downloaded and displayed the folders/emails as they are on my email server and now my hnych9cb.default is 3.7Go ....

This is a mess

Is there any way or hint to save the day ?
