I was running TB 128.11.1esr up until 10:00 this morning on Windows 10 Professional 22H2 64-bit. I have some e-mail messages that I cannot delete. This morning I auto-upgraded to 1o 128.12.0esr and then to 140.0esr. I still cannot delete the messages When I try to delete a group of messages (containing the message in question), the messages in the in-box turn from black to gray, and I see at the bottom "Moving messages to Trash". But nothing happens. I did a "Compact folders", and it completed without any error messages. I can look at my Trash folder, and the contents seem to be intact. In one case, I individually deleted all of the messages except one. With this one, I open the message and see nothing in the bottom message content pane. When I do a "cntl-u" to see the RFC 5322 message headers, I see a window that is completely blank. What is happening, and how can I debug this? Thanks.

What can I do about excessive memory usage by Firefox? I'm about ready to remove from my system. I get memory availability alerts from my very up to date Mac system only when Firefox is active. I've been with you for a LONG time so hate to leave but this is not a good situation.

Dear Technical Support

i repair it but Nothing happened.

How to Fixed it

Thank you

As of a few days ago (potentially coinciding with the most recent update?) I've had several websites become varying degrees of unresponsive when using Firefox while being connected to a VPN (Nord, in this case).

Some sites will load but then get throttled--i.e. YouTube will load and (usually) populate thumbnails, but clicking on a video will result in the video instantly dropping to its lowest available resolution, playing for a few seconds, and then stalling. Interestingly(?) if I try to watch a live stream, chat will be fully functional but the video will be unable to load. Other sites will load but then very quickly stop responding at all. Others are straight up just not loading period, while many others have no issues at all.

I've cleared my cache, deleted cookies for the affected sites, tried Firefox in a private window, tried Firefox with no extensions, and reinstalled both Nord and Firefox to no avail. All of the affected sites are fully functional so long as I'm not connected to a VPN, and are also fully functional on other browsers, even while connected to a VPN. All other non-browser related applications that require the internet are also unaffected, and my internet speeds in general aren't showing any issues.

I've been unable to find any other chatter about this anywhere, and I unfortunately don't have any other devices available to try and replicate the issues. I would not be surprised if it was one of those wonderful Me Exclusive DNS issues or something, but figured it was worth throwing out there.

Imagine having more than 30 Accounts to be added on a single profile my concern is how will Thunderbird handles file size if it's using one file (MBOX) and if the file has no solution, can I create files and keep mails on them until they reach max size?

This morning I opened Thunderbird and a Google Calendar reminder popped up. I clicked 'Dismiss' but the reminder did not disappear. I tried clicking the X close button but the reminder did not disappear.

The problem is that this prevents all access Thunderbird. Nothing is selectable so I have no access to my emails or to any of the Thunderbird settings.

I tried reinstalling Thunderbird (without deleting my profile) and the Google Calendar reminder pops up again.

So I am really stuck!

Can anyone help solve this issue please.

There were prob 20 or so, but now just blank tabs. My In Box and incoming email still show OK and I can read those in a new tab. but what about the old ones? And if I cannot recover, how can I remove those blank tabs. Deleting the usual way does not work.

On Windows 10. I wonder if Co Pilot has something to do with it

Thanks Tealeaf

ANNOYING!! I am unable to reach USA TODAY puzzles.

Window turns black with rotating arrow. I do not want to give in to BING, but I am able to work the puzzles when I use it.

I use Win 11 and normally use DUCK DUCK GO search

This is a technical question. Recently, Mozilla added the ability to manually restart the GPU process in about:processes, which is very useful when it leaks memory. Does anyone know if they also programmed Firefox to automatically restart the GPU process if its memory usage becomes suspiciously high, for example, if it exceeds a very high percentage of system RAM at a reasonable baseline (e.g. 7GB out of 8GB RAM)? That would help reduce complaints about GPU process memory leaks. Thanks.

We receive very large text emails from logwatch on one of our servers. Thunderbird becomes unresponsive for several minutes. When it "comes back" other messages can be selected but no content is displayed, and everything is slow to respond. Clicking the X to close the app takes upwards of 30 seconds to actually close the app.

Is there some setting to increase heap / RAM? Or is this a different issue?

Когда firefox зависает и windows предлагает его убить, firefox получает права системы и по этому становиться не убиваемым.Система не может его убить потому что у его права системы .В первые заметил этот баг когда сделал браузер firefox браузером по умолчанию.У меня сим роутер при запуске системы открывает браузер тут та браузер и зависает (не всегда ,но часто) в диспетчере задач в этот момент у его права системы.Писал в майрософт ,майкрософт посоветовал пользоваться нормальным браузером и сменить браузер по умолчанию .По совету майкрософт сменил браузер по умолчанию на chrome проблема пропала. Firefox 140.0.2 (64-разрядный) Windows 11 версия 24H2

When using the browser, my monitor starts to "blink". To be more precise, it just pops up a black screen for a second or two. I use both monitors and both go off, the cursor remains. There was no such thing before using the browser, but Firefox remains the only sensible browser, so I don't want to change it to something else. I've tried turning off hardware acceleration, but it doesn't help.

Hello!

I would be very grateful if you could help me figure it out, the browser suddenly stopped working, does not open any tabs, just a blank screen, does not open settings, some buttons simply do not respond at all. I cleaned the SScleaner yesterday, but I did not select anything special there, it was a basic regular cleaning that the program offers.

How do I fix this? reinstalling does not help, the browser still does not work

After letting Firefox idle for a bit (like 5 seconds) and nothing playing on the screen, when I come back, it causes screen stuttering for my whole desktop. Disabling hardware hardware acceleration doesn't help much.

AMD ReLive instant replay does not work if mozilla firefox is open in the background while playing a game. It works fine with Google Chrome running in the background, closing firefox "fixes" the issue.

When navigating through video websites, the browser often becomes unresponsive and refreshes the interface. When accessing other websites, the browser tabs frequently experience crashes.

Details regarding the operating system, laptop model, and browser version are provided below, and the screenshot of unresponsive website has been attached with this, um email or message.
