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.

Thunderbird keeps locking up. I have twice uninstalled and reinstalled, yet Thunderbird still locks up with the processing message. At this point, I want to know if 1) there is an online interface that I can try, and 2) If my emails can be salvaged somehow.

I tried the troubleshooting tips on the web, but I can't even get into the folders, even in troubleshooting mode.

My Thunderbird client install on a particular PC had a crash yesterday afternoon, and it appears that I have lost my folder structure and sent folder for one of the 5 email accounts that is set up in this client. The rest of the accounts in this client setup are fine. The account that experienced the crash was set up as a POP3 account, so I cannot just reload from the server. Unfortunately I did not back this thunderbird profile up recently enough. Is there anyway to recover what was lost? Is it hiding somewhere on the PC? ANy options to try?

For two days I'm having intermittent "hanging" when I'm typing a document or letter in Thunderbird. It has just dont that for the 2nd time in less than 10 minutes. Don't know what's happening but it's very frustrating. Am not having any other computer problems. Am running Windows 11 which is automatically updated by Windows. I think Thunderbird is the most current version too. Help please anyone! It does say "(Not Responding) at the very top of the page.

När jag ska starta E-postprogrammet går det inte. Jag får först meddelande om felstatus Oxc000012f. Sedan får jag kan inte ladda XPCOM. Vad betyder det? Måste jag ladda om programmet. Jag har använt programmet i många år och har mycket infor och kontakter där. HJÄLP

I have followed all the other recommendations with, no luck. I am on Windows 11 and use Eset virus software. Thunderbird is not listed as running it Task Manager, and there is no Profile.lock (think that was what it was called) in the profile directory, and I have deleted the existing profiles and recreated it. I have uninstalled and reinstall Thunderbird, and I have rebooted my computer. I am frustrated and concerned I will loose saved emails and my address book! Help.

Every time I open Thunderbird, I get the attached pop-up which I can't delete except when I use control alt delete. It always comes back. How can I permanently delete it? Thanks, Mark

I was using TB like normally on windows 11 when it crashed. Now every time i try to open the app it prompts me to send in a crash report, but every time i press "restart thunderbird" a new window with crash report shows up. I have tried writing a comment, checking and unchecking all the boxes and pressing quit thunderbird. But i still get sent into the loop.

I want to be able to switch a large chunk of my email archive "off" so it doesn't automatically load when Thunderbird launches (and consequently is invisible to search), but then bring it back online whenever I need to search deeply.

My Local Folders weigh in at 15 Gb. When Thunderbird launches, which currently takes a few minutes, Task Manager shows it takes up 1.8 Gb of memory, which I assume includes Thunderbird code plus an index it builds of all the messages in my folders. Not only does Thunderbird slow to a crawl and sometimes freeze up and crash, but this memory load appears to be slowing down my computer as a whole.

I can remove archives from the picture manually now: I can close Thunderbird, use File Manager to move the folders I want to be invisible to a location outside of Thunderbird's ken, and relaunch Thunderbird. And then reverse the process the next time I need to perform a deeper archive search. The fly in the ointment is that moving all those tens of thousands of EML files takes time and increases the possibility of file damage each time. It seems like moving the river to fill a bucket.

Another less than ideal solution now is to maintain two copies of Thunderbird, one for current and recent mail and another dedicated to archive folders. We'd have to perform a search in both Thunderbirds to be sure we'd found all instances of something.

I'd like to be able to simply toggle a local folder's visibility within the Thunderbird user interface.

Ideally, Thunderbird would be able to remove a folder from memory when I toggled it to invisible, increasing response time on the fly. But even if I had to reboot Thunderbird to get new visibility settings to affect its RAM footprint, being able to easily toggle folder visibility would still be a huge boon.

In the user interface, I imagine Toggle Folder Visibility added to the Tools menu. This function would display a checkbox next to each local folder showing its visibility status: checked for visible (the default), unchecked for hidden. It would be necessary to click Save for Thunderbird to act on changed visibility requests. Subsequently, hidden folders would be shown dimmed in the folder tree and their contents invisible. Searches would skip over them automatically.

Your thoughts?

Once I try to add a new email account and have entered the necessary data, I get the ad that the account will be created. However, the program simply hangs up and remains in that display.
