The app can be opened and used, but it has to load for about 2 minuter between each input. The error first appeared after the 7th August update. When I try and click on the app, it starts using about 125 MB of RAM memory and the "Not responding" text appears.

I'm on a M1 Mac Mini running Sonoma 14.6.1, and my Thunderbird quit several times. I restarted and this time it isn't coming up at all. I'm going to try shutting down and then starting up after a few minutes. It started after I made a new Folder n TB and put a file into it from Experian.

Hello!

A very important email folder in my Thunderbird just vanished. I didn't touch anything! My email was downloading very slowly and so I closed the entire Thunderbird application. When I re-opened it, the folder was gone. Everything else is there as before - all other folders, my inbox etc.

I have no idea what happened or where the folder went. I can't find anything online that addresses the problem or how to solve it. I'm very much a tech novice. I need a solution that a 5 year old could navigate lol

Hey, im having some issues with Thunderbird recently.. Its been freezing and lagging for last two days, probably newest update causes that.. any other idea what could it be? Its happening on every device at my workplace. Mozilla team, fix it please. Thunderbird is our working tool.

unable to use Thunderbird, try to open program and all I get is a white screen for 2-4 seconds, then a crash report pops up. Unable to get any further. Have uninstalled, cleared cache, reboot, then reinstall. Help appreciated. Win 10. Kevin

I have accounts from Outlook Mail through GoDaddy and Gmail on my Thunderbird desktop app. After the update on 9/17/24 I am unable to send from any of my 3 accounts. Please help.

I either can't view contents of any of my older emails in Thunderbird at all (see accompanying picture), or in some cases, they just show html text code. (Both the inbox and sent directories are affected.) I have followed the Thunderbird troubleshooting suggestions (e.g. disabling add-ons), and clearing the cache, but the problem remains.

My Thunderbird mail directory on the PC is D:\All Users\Thunderbird\Profiles\Macdonald\Mail\pop.broadband.rogers.com\inbox.sbd

FYI - The inbox contains ~7600 messages, while Sent has ~2180 messages.

Hope you can help me out with this issue. Thanks!

Ever since I upgraded to 115.10.1 (from a much earlier version, which worked well), Thunderbird is randomly very slow.

First off, at opening time, it takes ages (over a minute) to download some incoming (small) messages - while this was definitely not the case with the previous version I was running. Sometimes, it hangs (for anywhere from 15 to 60 seconds) while I am typing a message.

Also, e.g. today, I tried to send an email (250 KB or so): it just kept on saying "sending". When I clicked (after a few minutes) to stop the sending, the window closed without further ado and I couldn't find the message anywhere (not in the Drafts, not in the Sent). I did it again, it then hung on copying the message to the "sent" folder. When it finally said it failed, and asked if I wanted to have it copied to a local folder, I clicked "yes". Upon checking, it had stored it in the "sent" messages, not locally...

I am running Windows 10 Pro, with ample memory and disk space, and a fiber optics connection. The CPU is not overloaded at all nor any other ressource.

It is becoming increasingly annoying.

TB 128.3 did not work in Mac OS 15.0 Sequoia. So I called Apple, and they helped me re-install TB. It works fine now, but the layout looks weird. Instead of

Subject of message on left sender in middle date on right

I now get

Subject of message on left sender underneath date on right

How can I fix it? It is using a lot of white space around everything

Thank you

Recently, my bookmarks have disappeared (but leaving empty folders), reappeared, or reappeared but incompletely. (incompletely meaning not all showed up - alphabetically, only bookmarks beginning through letter "D." When I search bookmarks, the "missing ones" show-up in the results; they are just not visible in the toolbar. Similarly, if I try to add a new bookmark, it does not show. Help! thanks

This happened too much, like 6 times when using firefox in this month. I dont want to shut the program because I got unsaved notes in it. I was listening to music and it just began to play it non stop. and it dont respond.

please help, a million thanks!

I try to restart network or suspend the process nothing works. If I could make firefox reopen to it's original state+ cookies; no site reloaded and get back my incogico it would be much appreaciated. ALso everything was saved in firefox since I did not end the task, I dont want to lose those.

There is a website https //secure.exeloncorp.com/login that will not load using FireFox. It will load using Google Chrome. Is this a function of the Website or FireFox? Is there a setting in FireFox that will fix it?

Near Firefox. Why does Firefox's built-in translator always write “Near” in front of all opening sentences? It's very annoying to look at. Have you considered using AI? DeepL is great for translating. It translates not only the words, but also the culture.

I've been using FF since release #3 and like it a lot since I cut my teeth using NetScape. The past few days FF will not open one of my email accounts. When I click on login, it brings up the logging on page and then just starts blinking and will not sign me on. If I use MS Edge to sign on it works fine. The email account has been working fine for many years so don't know what to do. I've deleted recent history, but that does not help. Any ideas will be appreciated as I like FF and don't like to have to use two different browsers to do my daily tasks. Thanks in advance for any help you can suggest. I'm currently using release 131.0.3 with W-10 on a desk top PC with DSL from my phone company with the email account with their ID. My phone company does no know about or support FF.

On my Windows 7 machine, I am running Firefox V115.17.0esr (64 bit). When using Task Manager yesterday, I noticed the process spNMHost.exe whose description reads "Autofill Engine host for Chromium-based web browsers", but this process is started by Firefox (and ends when Firefox closes).

What the heck is going on?

Thunderbird Quick Filter Toolbar has suddenly started splashing a couple popups when I start typing in the filter box. These popups effectively say "... click to..." but don't actually let me click; they just block the screen.
