After I open my Thunderbird email and use it for 15 to 20 minutes it freezes. I need to close it and I get a message Thunderbird is not responding. I then need to close the program using Microsoft to close the program.

For the past few weeks I have been having constant crashes in the form of tabs crashing and complete browser crashes. I have tried disabling every single extension, still crash. it even crashes in troubleshoot mode. In fact its crashed while I am writing this. Seriously thinking about giving up entirely on this browser and switching.

the latest crash report submitted : bp-5ca96001-20a8-4097-ae0d-9a42d0260630 bp-aba4b1dc-6248-4516-bf35-3f19d0260630 bp-c222bd57-f884-49e6-a3a7-be7130260630

Since the 152.0 update I've experienced near nonstop browser crashing, it crashed twice as I was trying to type up and submit this message,

Is this a known issue or solely on my end? running 64 bit, windows 10

I don't want to spend any more on my PC. It was the largest amount of money I had ever seen when I first bought it. Even if I have way more resources now, I don't believe that a few faulty locations in my memory should be causing so many problems for myself and for developers who have no clue why their users keep crashing.

It is either my RAM or VRAM. Disabling XMP on my RAM dampened these issues but couldn't fully solve them.

It's exactly as I said. Normal programs just crash. Kernel-level programs or anti-cheats can entirely blue screen my PC. It all has to do with where these programs are writing to in my hardware. It's only a few locations that I have faulty. Most programs work fine. Most games work fine. Most crashes are very transient.

Firefox is a transient and common crasher for me. It's so painful to be scrolling a page and have the page crash, just for the previous page to load instead of the newer one that I was on, and on top of that I could also be losing work or effort.

I know this isn't exactly a dev support page, but this problem is so recurring that I don't know what to think anymore. There has to be a way to check which memory locations are fried without causing a bluescreen or crashing the program. Maybe it's a Windows issue and devs could easily fix it, if it weren't for Windows bottlenecks like labelling the faulty locations as "protected". I've seen at least 1 crash where the output said something like "Error: tried writing to protected location" blah blah blah then it spit out some hexcode or exact location and blahblahblah. And that was the entire error message.

Every time I attempt to log into X.com the Firefox browser stops working entirely. Dead. Nothing. Won't open or function. Need to restart my computer to access and use Firefox. This does not happen when I use Chrome.

Стали постоянно падать вкладки при открытии новых страниц.

Весь браузер не зависает. Перезапуск браузера не помогает. Windows-11. Версия FireFox 152.0.1. Обновляла неделю назад. Не помогло. Сейчас попробую обновить до 152.0.3.

Как расшифровать причины ?

As I write I am seriously considering walking away from using Firefox and advising all my friends to not use it.

Every time a programme does a update on my desktop, which is several times a week, it crashes Firefox and I get endless messages all day to keep rebooting Firefox.

It is getting extremely aggravating, frustrating and making me very annoyed.

This is supposed to be a modern browser with no big issues, supposedly easier to use than others? not on my desktop it is not and has not been for several months.

About 3-4 months ago I started experiencing frequent tab crashes, to the point where if I have even 2 tabs open, one will be non-responsive until the crash page appears. Sometimes not even then, as I've just had YouTube up and it will crash with shocking regularity.

I used to be able to have 20+ tabs open plus a game with no issue at all. I've done nothing different with my computer, no new hardware, no new software besides installing and uninstalling games. My upload and download speeds remain the same. Only Firefox is being a stinker.

What's happening?

Other than being slow to download my emails now for a few months, TB was performing well until a week or so ago. Now it also won't open the downloaded email when I click on it and the TB freezes up so I can't close it out. I have tried restarting computer multiple times and it works for one or two emails that I can open and then starts freezing up again. Makes using it almost impossible. I have security Windows 11 Defender only and have had it the entire time when it also worked well.

Firefox keeps crashing. It was doing it even when I first got my phone, just not as much. I use Firefox on my laptop and like to be able to connect them both and the privacy or I would have gone to something else on the phone. Samsung A71 5g. I don't use 5g even thoygh the phone is capable of it. I don't trust 5g. I know the phone is old enough it doesn't get updates anymore, but I don't like the newer phones (no sd card being one of them).

Firebird is so slow now, that I can rarely receive the code that you send me. Have to take annother programm for that. Freezes even when trying to mark a mail or erasing it. WIN 11. The programm is working well at my wifes laptop also WIN 11. 2 month ago it worked fast and fine. Working in Troubleshooting mode does not show any spam ordner like before and it does not run better. I also downloaded the last version. No change! I would like to uninstall the programm but did not dare due to perhaps loose all my mails. Could you help me please? Thank you!

Firefox keeps suddenly crashing, I have reset Firefox, deleted it and reinstalled it, I have used DISM and SFC to repair any issues and I have set up a new profile within Firefox with no extensions, but still I have the same issue, either tabs suddenly crash or the whole Firefox does.

Hello, It's been a few days Thunderbird freezes when I want to save a message on the computer (save as). When I close the saving window which is not responding, it automatically saves the message on my desktop. The file where the last message was successfully saved is still existing so I don't think it is a path problem. I have tried to restart it without the add-on but it doesn't change anything. And it is up-to-date. Anyone knows what the problem could be? Thank you! Estelle
