I have about a dozen accounts with over 50 folders, most with a matching filter. About 100k messages, taking up about 1G of disk space. All but one account is merged under my Inbox to have fewer duplicate In/Draft/Sent boxes eating up window space. I'm using 152.0.1 (aarch64) Release branch on a Mac OS X 26. All are POP accounts on a DreamHost server.

At some point it started to show the draft message on every email, which means on incoming as well. I've had this phenomenon for years.

Recently filtering has started to not automatically run on some emails forcing me to run the filters manually. I've run the repair folder options which does not seem to make any difference.

Since switching to macOS 26 it also does not allow me to move Thunderbird child windows, they simply show up on the default location. But that's for another ticket.

I have followed all instructions I can find through many searches online but cannot get my outlook email to configure in Thunderbird. First, I have no option to chose OAuth2 even though I have deleted any outlook passwords, email accounts, and Thunderbird is up to date. I have received so many error messages I cant keep track. Bottom line, all my other email accounts configure find except for outlook. Any help would be appreciated Steven Pecoraro

Sometimes a search term will pull up many emails I need to sift though, like in the case where it's a common word, like permit. I was searching the term "permit" for building permit emails and got many unrelated emails that were more recent with permit in the email body. I am able to quickly skim and see these are unrelated but the limiting factor is only ten results per page. When I click load more, takes a few moments to load. I was unable to find any way to change this. How can it be done? Should be possible, it's doesn't affect Mozilla's processing because everything is done locally on my machine. I would much rather 100 results to load or to load indefinitely.

Additional question: on that search term, many unrelated emails came up as mentioned before. When I searched the same term in gmail in my internet browser, only relevant emails came up. Why is this? How do I improve the thunderbird search?

I've been using TB for many years, and without warning, when it tries to down load my mail from the Proton mail server, it says it can't find the folder "Inbox". I've tried to "repair" that folder a couple times unsuccessfully. I've restarted the TB program a couple times, but nothing changes. The error shows up on the bottom "instruction line". I've gone through all my settings and find nothing amiss. Not sure where to go from here. -- Just noticed that I had about 80 emails in that Inbox folder that are now missing completely. Normally, I move read emails to there respective folders, and leave important ones in the Inbox for followup. One significant note here, is I'm still using Win 7 premium. So far it hasn't been a problem. Thanks a bunch, Gerald

Under installed apps I have two entries for Thunderbird: 1) 140.8.0, 2/25/2026, 244 GB (sic) and 2) 140.12.1, 7/2/2026, 250 GB. Is it safe to temove 1), and how is it possible to be that large an app?

Please let me know if it is safe to remove the older version of Thunderbird in the Installed Apps list. I also question whether the size of the app in the list is accurate; 250 GB seems quite enormous in a 500 GB hard drive. Thanks, Hans

Thunderbird/Lightning Calendar on Desktop - problem displaying monthly repeating events

Thunderbird Version 152.0 Manjaro KDE Plasma 6.6.5 Kernel 6.18.36-1-MANJARO (64-bit) Graphics Platform Wayland ThinkPad T420

Successfully added monthly-repeating event for the first day of each month beginning at 00:00 hour with duration 0:00. These events correctly appear in another calendar (Google). This also shows there is no confusion between 'monthly' and '4-weekly'.

In Thunderbird's Calendar display, these events do not appear in day, week- and month-view modes, when the first of the month is the first day to be displayed. When the first of the month is positioned further into that view-mode's display then that repeating-event is correctly displayed.

The above happens in Thunderbird's Safe Mode with all add-ons disabled.

Many thanks PS. I am unable to report a bug in Bugzilla due to having lost login-credentials.

I'm trying to move from Windows to Linux without downloading all my imap messages again. What I've tried: 1. Install tbird on Linux, create new profile. 2. Close tbird. 3. Using Linux file manager,

 - delete contents of new profile folder
 - copy contents of old profile folder into new folder
 - delete Compatibility.ini in the copy

4. Open tbird with -p (profile manager)

I've tried twice with different results. The first time at step 4 I started offline. Thunderbird opened will all my previous tabs open, except that all the internet tabs reported connection failure - as expected. Under account settings, both local folders and my gmail account reported the correct (new, linux) path. When I went online and completed the gmail OAuth dialog thunderbird reported an inbox summary folder error, and deleted all the imap mbox files. I closed and restarted tbird- which failed with a crash dump. the terminal window reported successful minidump creation- the file manager showed the minidump file at zero size.

I repeated the process (recreating the original unmodified profile). This time at step 4 I started online, and tbird never opened- it generated the crash dump immediately.

Two questions: 1. Is it possible to transfer an imap profile and avoid re-downloading all the old messages? 2. What am I doing wrong that I'm getting the crash dumps?

With a new Thunderbird installation on Windows 10 Pro, I attempted to import my profile data from a Postbox on another machine. The process failed, citing two errors (see attached screen shot), EmptyDatabase Error: "blocklists/addons-bloomfilters" has not been synced yet Uncaught NS_ERROR_FILE_NO_DEVICE_SPACE: Component returned failure code: 0X805200010

The profile being imported is pretty large -- around 20Gb, so I wonder whether I have surpassed some capacity limit. I was doing this via the Import Tool on the Tools menu.

Porting my legacy mail folders is crucial. Any help would be greatly appreciated.
