Running Windows 10 (have extended security updates). Starting at version 153.0 Firefox hangs (spinning cursor) until Windows realizes it is not responding and lets me stop the program. Seems to be independent of the website (even happened on a Mozilla page). Have tried a couple of 153.xx updates and also 154 but behaves the same. On a Dell Inspiron 7570:

When trying to open Thunderbird it does nt with the message "Thunderbird Not Responding" I try to open in Troubleshoot mode but that does not wotk either. I have to start and re start the laptop and finally after many tries it finally opens. Frustrating

After reading my emails, I wanted to look at my address book. I clicked on ADDRESS BOOK and my book was not there. Now, I can't back up to a normal page. The only choice is to go to the taskbar and close that page. Then when I restart Thunderbird, I get the same useless page ! Now how do I get my emails ? PS I cannot get to the HELP page of Thunderbird in order to find the version number, so the number I posted below is probably wrong. But otherwise, I could not SUBMIT my plea for help. I'm really stuck !!

Yesterday and today I am opening Email and clicking on new message, as soon as I try to type in the email address that I am trying to send email to it disappears and I get error message and then I have to go back and open Email again.

Error: bp-57bcdd30-438c-4af8-9e75-b5c9b0260822 OS: Linux Mint 22.3 Device: IdeaPad 3 15ARE05, CPU: AMD Ryzen 3 4300U, GPU: AMD ATI Radeon RX Vega 6, RAM: 8Gb

I used firefox troubleshoot mode to see if the problem is caused by an extension etc. But my tabs were still crashing, this time, firefox as a whole crashed. Sometimes a tab crashes, and sometimes firefox crashes. I tried to troubleshoot with an llm, it said that i don´t have enough RAM, i have 8Gb, but its shared between RAM and VRAM. I was on fedora before, the problem occurred there so i switched to mint with the thought that mint is more lightweight so it should have more RAM available for tabs. But that wasn´t the case. Sometimes i only have 1 tab open, nothing else on firefox and on my laptop open at that time, but the tab still crashes.

I hope i´ve provided enough information, if not, let me know what your missing to fix and i hope i can provide it :)

Why is Firefox always crashing on Windows-XI, especially from third-party servers and whenever scrolling? This has been happening for the last nine months (ver.146>Beta), at least. Does my SSD need replaced and/or my Win-XI reinstalled? Either way, this is happening on every Firefox browser that I have, including Windows-XPIII> and Android-16>. This is where my team always swore that Java6>, .Net3>, Python3>, and even Swift3> love to crash all user-interfaces/shells, and make users lose all random access memory. Is there any suggestion to fix this bug of Firefox, or must I replace the SSD?

My problem is that I can’t get into Thunderbird because each time I start it up I’m presented with a window that says "System Integration" (Not Responding)" and I have no way of making progress – all I can do is use Task Manager to exit TB.

The “system integration” window first appeared a few days ago and initially I was able to dismiss it by choosing the “Skip integration” option. Today was the first time it became unresponsive. No changes have been made to the system and TB should be up to date – though, not being able to open TB, I can’t check the version number (probably esr).

I have used TB for many years and have it installed on two PCs, both running on Windows 11. It’s working as normal on the other computer.

I’ve tried rebooting the computer, to no effect. I’ve also tried to open TB in troubleshooting mode but can’t get past the "System Integration" (Not Responding)" window.

It’s been a couple of months since I backed up so I’m really hoping there will be a solution that preserves all my emails, address book and calendar.

I’d be very grateful for any suggestions.

I wanted to share a specific startup freeze loop I encountered today.

I had a moderate number of tabs open in Thunderbird when I quit the app. I had set up a single IMAP message filter yesterday to automatically move incoming automated text alerts into their own folder (causing about 50–60 small emails arriving in quick succession this morning at startup).

The Problem: Upon starting up, the app almost immediately choked and became unresponsive. Unlike the freeze report by another user here on August 21st.

My Workaround: After a few attempts to open Thunderbird I managed to break the freeze loop by instantly closing the single open UI window right at startup. This kept T-bird running invisibly in the macOS background. It seemed that without the need of rendering the UI, the background engine successfully completed all the IMAP syncing and filtering tasks.

When I brought Thunderbird back to the foreground, all my open tabs instantly "snapped", and the app has been perfectly stable since. I haven't tried to replicate this due to the fear of breaking the current stability.

Has anyone else recently noticed Thunderbird freezing under similar conditions lately? Let us know if this workaround helps you get past your startup freezes too!

Moderator note: This question has been edited to correct the formatting.

how do I configure the account to minimize CPU resources when thunderbird starts up. Once I can get thuderbird to start OK, what are the next steps. It is likely this user has not powered this machine down more often than once every few months. And thanks, I don't anyone else who uses their computer like this.

can you add an option into the program that when it cant read the local emails from the disk for some reason, then it would ask for my permission to re-download everything and/or add an option to close or restart the program?

there is some really annoying bug when the Pc is in the process of using all of the available Ram (for some reason) and when i open TB at the same time, everything gets really slow, and instead of actually pausing to figure out what is wrong, the ******** ********** ****** just starts to throw in even more work to download all of the emails again for some reason, not even giving any explanation why it wants to do it in the 1st place....................... (while the screen even just blanks out, just because there isnt enough Ram avail to display all of this *********** *****........)

SHello Sometimes, on my iMac APPLE (OS Tahoe), THUNDERBIRD stops opening (message system: not responding ("ne répond pas" in French) There is no problem when launching the application, but issues arise later when returning to it after using other applications (Word, Excel, videos, etc.), THUNDERBIRD tourne en rond et ne s'ouvre plus. I have to close the application (via my Mac's system settings) and relaunch it for it to open normally again. I would appreciate any help if someone has experienced the same kind of issue. VAJP
