My Thunderbird 115.10.2 (64 bit) is lately running very slowly. Message content takes forever to show. Sometimes don't show at all. Sent messages take 20s to save.

I was thinking that my files were simply too large, so I erase everything before 2022-01-01. Where we are now:

  Inbox            13,662 messages 3.0 gb
  All Mail         22,722 messages 5.8 gb
  Sent mail       5,175 messages  1.2 gb
  Important    13,093 messages  3.1 gb
  Other             4,700 messages (approx)

Questions: 1. Can I delete the "Important" messages, thereby perhaps freeing up 3.1 gb? In which case how do I do that?

2. Does this look like too many messages for TB? It's two and a half years worth. Like to keep it, but not at the expense of making the system so slow.

I have removed the databases twice and started with a new instance of TB, which is where we are now.

Thanks for any suggestions!

115.05 when I started.

I typically open Thunderbird about once a month, download my emails from a hosted website, do some clean up, write some emails, close Thunderbird, and do the same about a month later.

Today I opened Thunderbird, saw that it was downloading around 400 emails in the lower left corner, and waited patiently, as per usual. When "done", however, none of them showed up in the main window. The latest email did not change, was still from around a month ago. When I ask Thunderbird to Get Messages it says there are no new emails to download.

I restarted Thunderbird several times, no change.

I then upgraded to 115.10, hoping this might fix the issue, but it has not.

Since restarting Thunderbird, 2 new emails have come in and are showing correctly, but none of the initial 400 emails "downloaded" today are showing anywhere.

I repaired the Inbox folder (right click > Properties > Repair Folder), no help. I renamed the "Inbox.msf" file and had Thunderbird rebuild it, no help. I renamed the "global-messages-db.sqlite" file and had Thunderbird rebuild it, no help. View Ignored Threads does not help. View > Threads > All is selected. Emails are not in the Trash folder, or any other folder.

All of the initial batch of 400 emails - and the emails I had previously opened - just disappeared.

Opening up the Inbox MBOX file directly, I can see that these 400 emails were never actually downloaded into this file. Not sure what happened.

Opening up my remote email host, I can see that those 400 emails are still there, to the exact point when I last closed Thunderbird.

Asking Thunderbird to download new messages does not download these remote emails.

How do I reset Thunderbird to start the process over and re-download these emails again? Part of TB seems to think it's already downloaded these emails, while another part of TB never actually did.

Does anyone have any idea what to do here?

The same happens in troubleshoot mode. I also tried reinstalling an older version but the same thing happens. Help me figure out what's wrong so I can read emails. :(

I can hear NO AUDIO on ANY webpage, when in Firefox. I have gone through all the suggestions on this page: [https://support.mozilla.org/en-US/kb/what-to-do-if-firefox-wont-play-any-...] but still have the problem.

I notice this subject has been mentioned prior, but I cannot find a resolve. Been using Thunderbird for a long time without issues, but last week it stopped sending and receiving emails through the Skymesh internet provider. Still sends & receives Hotmail/Gmail/Yahoo, but will not connect to any Skymesh accounts. Have reinstalled/updated, but no change. SMTP timeout and if I change settings I get the 10060 error. Could not even connect to their Webmail page either. If I turn VPN on, then I can access their Webmail page. Rang Skymesh, they poked around and said it was all this end and with Thunderbird. Seems an IP number change via VPN with Opera resolved the Webmail page access, but I cannot do that thru Thunderbird. Running Win 7. Anyone ??

Somebody thought that it is a GREAT idea to make drag-n-drop cursor a GIANT rectanglular thumbnail of the emails being dragged.

No, this is a horrible idea because that thumbnail covers the target of the drag-and-drop.

Either REVERT this IMMEDIATELY or let us know how to disable and revert to the simple drag-n-drop mouse cursor that does not obstruct the target of the drag.

And in the future AVOID any GUI changes that are not ABSOLUTELY NECESSARY. With these poorly thought through, extremely annoying changes you are only causing damage and aggravation.

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.

Samsung Galaxy S24 Ultra running latest Android update and latest Firefox update. I set Firefox as my default browser. I have un-installed all updates for Samsung Internet and removed all permissions for it. Disabling it is greyed out. Some apps that I use have links to websites. Too frequently, when I go to one of those links, the intro screen for Samsung Internet opens. Then, when I look at the settings in Firefox it is no longer set as the default. Then I set Firefox to default and go to my phone settings to see that Firefox is selected as the default. If I open the previously mentioned app and choose the web link, Firefox will open. But somewhere along the way, the default changes back to Samsung Internet and it's a vicious circle. I have posted in a Samsung forum but haven't gotten a reply that solved the problem. Please help. Thanks Mike

I attempt to open Thunderbird in an iMac but the computer says it is already open and only one can be open at a time. I can not find a Thunderbird open on the computer.

When accessing my site (in attachment to avoid indexing), Firefox blocks with a "Possible security risk" interstitial. DoH requests to the configured https://dns.google/dns-query service work from an external application on the same machine as the browser, but about:networking#dnslookuptool reports the host being unknown.

Thunderbird 115.10.1

If I attempt to print many emails at one time (by selecting a group of them from a mailbox), Thunderbird sometimes gets lost in the middle of the job and chooses a random email (not from the selected group or even the same mailbox) and combines many others into the same email and tries to print (leading to a single email showing 200+ pages for that one entry in the print queue and actually composed of many emails put together, but not the ones I selected).

Does not happen if I only select a few emails at a time.

Sounds like an indexing issue with the file that holds all the emails. Perhaps something gets corrupted?

Any suggestions?

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

I keep several email tabs open that have topics I am currently working on with clients. Recently they have been turning blank, so I have no idea what they are--I feel I have lost info that I need to do business. Why do they turn blank? I need this fixed ASAP!

We are using a website designed for Firefox, and when we use the "print" function within the website tool bar, on one of our PCs, it always defaults to a print preview which states "Printing from Win32 Application - Print". We have "print.always_print_silent" set to true, on this and all of the other PCs using the website, but only this PC has the issue. We can't figure out what is making it pop up the print preview.

Hi. I have this strage problem X writes a mail to "support". "Support" is a distribution list. I receive that mail

I then reply to X. Sender is "support" as it is defined as an Identity under the main mailbox Also there is a rule in that identity to sens a cc copy to support itself (so collegues belonging to list "support" receive a copy)

I then need to send a second email to X, starting from the sent message (as it is a follow up)

So i go under "sent mail", i find the message i sent previously, having from "support" to: X cc "support"

(1) I click reply and i get a message with: - from "support" - to "support" - cc "support"

So "X" has disappeared

(2) Note I have no button "reply to all", but if i right click the masse and the "reply to all", i got a good message with: - from "support" - to "X" - cc "support"

Hope this is clear. Someone can help ? My need is click reply and get result as described at (2) Thank you
