Thunderbird Community Forum

Hi there,

I just installed TB recently. I have configured my Gmail account to be used on TB using IMAP. I am noticing that TB is downloading all my emails from my Gmail. I do not want this. I only want to see the header of the emails, and if I click on the email, then it can download it. I don't want TB to take up a lot of space on my laptop.

Do you have any suggestions on how I can do this? If this question has been answered earlier, a link to that post will be appreciated.

Since updating Thunderbird lately to 128.3.3esr (64-bit), "Open in conversation" is grayed out, SHIFT+CTRL+O shortcut also doesn't work. There is a small chance it happened on a previous update, I'm not sure. This function is something I use regularly so this bothers me greatly. I tried rebuilding the global database according to https://support.mozilla.org/en-US/kb/rebuilding-global-database with no luck - the problem persists. The file now has 1,18 MB, I'm quite certain it was significantly larger before. The problem occurs in all accounts I have and it worked on all of them before. Threading itself works properly if I go to View>Sort by>Threaded so the messages are recognized as threads properly.

I use 2 different gmail accounts for different purposes. I get mail for AccountA via IMAP on Thunderbird, no problem, and have for years. For over a year now I've been unable to collect mail for my second-string address, AccountB, on Thunderbird, and have had to get it in the browser.

I've finally decided to do something about this. I removed AccountB from Thunderbird & set it up again. I'm using the exact same settings (in Thunderbird and in Gmail) that I do for AccountA, the only difference is the password. I've double-checked the password, too. But when I try to connect, I get a pop-up:

titled: Enter credentials for AccountB@gmail.com on imap.gmail.com [a very long URL which I've copied & saved] page from Google:

400. That's an error. The server cannot process the request because it is malformed. It should not be retried. That's all we know.

Thanks a heap, guys!

Is this problem coming from Thunderbird, or from Google? What do I do now?

Thanks,

MEC

I had a gmail account, I no longer have the gmail account. I deleted the IMAP and SMTP entries. I have no CardDAV entry for that account, no calendar entry, and no chat entry (that I can see; but that old account is lurking somewhere). None of my extensions use (user-configurable) credentials.

What else is there? Is there a way that I can search Thunderbird's config for the account username?

I'm about to screenshot settings, archive this profile, and start anew. I'd really like to avoid that, because I have collected >10 email accounts over the decades and setting everything back up all at once seems a hassle.

What are next troubleshooting steps? TIA for any wisdom or guidance.

I recently installed Thunderbird on a new installation of Ubuntu 24.04 using the "Installing Thunderbird manually" instructions. Everything works fine except that Thunderbird doesn't want to use the Thunderbird icon in the dock. Thunderbird opens and runs fine when I click on the Thunderbird icon, but it then puts a new default icon on the dock that looks like a gear instead of just "using" the Thunderbird icon to indicate that the application is running. I've attached a screenshot. When I close Thunderbird, the gear icon disappears.

For years I used Thunderbird to process my Earthlink emails. Thunderbird suddenly stopped accepting my Earthlink password, which I repeatedly tried and reset. Is something wrong with my Thunderbird settings? Mac IOS 13.7.1

I have a profile on a disk from a Windows 10 machine that recently died. I have a Windows 11 laptop that I just installed Thunderbird on, and I tried a profile import from the tools. It was able to successfully import my address book as well as my local folders, but did not import my calendar events or my sub folders under my inbox. Is there any way for me to get this data imported? Thanks, Gary

Help please. Thunderbird often puts the wrong headers on emails. So the headers (subject, senders, etc) from one email are placed on the text of another email, and I end up having to delete the email and lose the information. Any way to fix when it happens again? Thanks

When I make changes in the settingsscreen the changes are NOT be saved. Since the latest update 128.4.3esr I get everytime a donate screen. But I donated serveral times last month. How get I lost off it!!!

Hi,

Starting less than a week ago Thunderbird has been running slowly. Sometimes it's quite noticeable and sometime not so much. E.g. clicking on a different folder sometimes happens immediately and sometimes takes maybe 4 sec. to display the folder. Clicking on a message sometimes displays it immediately but can take 7 or 8 secs. to display. Receiving messages seems normal and I haven't noticed slower speeds sending. Clicking on Reply for a message can take several seconds, and dragging a message to a different folder can do the same. Once I'm editing a message the edit speed is normal with no slow down and the address book and editing filters are both fast. I didn't make any changes to Thunderbird, this just started happening on it's own.

I'm running Thunderbird ver. 128.4esr (32-bit) on a windows 10 desktop PC using POP to access messages. I ran Compact on all the folders to no benefit. I don't know what else to try.

Please let me know how to correct this or figure out what's going on.

Thanks, Mike

I recently upgraded my OS from WIN 8.1 to WIN 10.0. Previously, I had installed Thunderbird in order to download my Gmail messages etc and import them to TB locally for archival purposes. When I upgraded to WIN 10.0, it was a clean install so TB and all the data was deleted. I have backups of the Gmail files I previously imported to TB but it seems the instructions are not clear on how to get them back into TB locally. I want to be able to search and read these emails when needed, since I deleted them from the Gmail server

Since font size is controlled in Firefox by CTL +/- why not the same for the main screen in Thunderbird? Eyesight requires larger characters. Simple solution best. Past my time to futz.

On my old small laptop I wanted to increase interface font size. Erroneously thought that in layout.css.devPixelsPerPx I could insert the desired font size. I have inserted 12, now Thunderbird is unusable, some giant menu words appear but I cannot move anywhere. Can I I edit a configuration file manually to reset to a readable size? Which?

Made a mistake by changing user_pref("layout.css.devPixelsPerPx" from I think - 0.5 to +0.5 as incoming emails font was miniscule, but made nor difference... so thought it may be a font size, so changed to 12.... Now ginormous and unreadable. Searched through pages here for an answer and got to the prefs.js folder to find this file but it is not there.... I searched with notepad edit search for "layout" but no luck. Any ideas anyone? I tried adding the line user_pref("layout.css.devPixelsPerPx", "1.5"); whilst TB was closed and then opened TB but had made no difference.. :-( Any ideas anyone? TIA Graham
