For the past month or so, Thunderbird has stopped providing me with emails as swiftly and reliably as it has been for many years. When starting the application; In the bottom of Thunderbird I can see it seems to do all the checks to the mailservers correctly, it just doesn't download any new emails. Nine out of ten times, it doesn't work. Then, all of sudden, once in a while, it actually does work. It's really irritating and I'm considering switching to another mail application. Currently, I can access my mail by logging on to the webmail, but it would be so much nicer if Thunderbird would work just as it is intended. Kind Regards from a user in Denmark, Scandinavia. Version: 140.5.0esr

I have received a new strong computer and I have now different kinds of problems. When above mentioned e-mail program was installed, my maps on left side are not in alphabetical order as it used to be. Unfortunately the installer man has not been able to sort that out. Do you have a solution I can inform him? Best regards Calle Sand E-mail: [edited email from support forum]

I'd like my search results to include messages where the search item is in the Sender or Subject but it appears to find only words in the body. Is there a way to include this? btw, the window pane on the left shows a filter but I don't know how it got there or how to delete it. Is this relevant? Is there documentation on how to use the search feature to specify folders, binary searches, etc? Thanks

The previously opaque/white search widget suddenly became transparent and disappears into my home screen. I didn't enable this, but I can't find the setting to make it opaque/white again.

Searched for "widget," "search," "transparen" in about:config, toggled various settings, nothing worked. Looked in secret settings, nothing.

Really bad implementation decision: don't change user's existing UI just because you, or other users, like it and think it's a good idea. Opt in, not opt out.

Background I am currently migrating from Windows to Linux/Ubuntu (finally). So I am a beginner in Linux (intermediate in Windows).

As part of this I need to replace my Microsoft Outlook. In Linux there are a few to choose from. For example: Evolution, KDE Kontact/KOrganizer and Thunderbird.

Aside from some compatibility issues with G-mail, I was overall happy with Outlook for the following reasons – which are also what I wish I could get out of, preferably one, or more, equivalent personal information manager programs (PIM) in Ubuntu:

• Calendar

- Absolutely ok. - Good overview and synchronization with other parts of Outlook - Stylish, useful and clear graphics

• Task function (To-do)

- Very good: 

- Shown in all views (email, calendar) - Good time division: Today, tomorrow, this week, next week, month, etc. * Great possibilities for setting up and designing your tasks (in everything from designing quite complex projects to graphic outline and layout) - Completed tasks are saved automatically and are very easy to access in a separate window (to the left of current and upcoming tasks), where all tasks are also searchable through the search function at the top. Very useful when you need a history of various projects/tasks, etc., that you have completed. For me, absolutely crucial! - Good synchronization with the calendar: Shown, for example, at the bottom of the Calendar for each day. - Quite stylish, useful and clear graphics

• Contacts/Address Book

- Also quite ok - Synchronized with other parts. - Stylish, useful and clear graphics

• Email

- Quite ok, apart from the aforementioned synchronization problem with G-mail - I completely abandoned IMAP and switched to managing all email online, which is an obvious deterioration: G-mail online is not the world's most intuitive tool for someone who handles large amounts of email with the administration and control needs that this entails. - Plenty of settings - Quite ok synchronization. - Stylish, useful and clear graphics

The version of Ubuntu I'm using is 24.04. It comes with Thunderbird. But only as an email client (no calendar, no To-do app, no address book, etc.). Which was a bit of a disappointment. It's a full-fledged PIM that I need.

So to start with, I tried Evolution. I don't want to say that Evolution is bad, but it didn't work for my purposes - and in many respects felt quite outdated. Maybe it would be possible to get more out of it if you explored and tested it more, but after a couple of weeks of evaluation, I set my limit. But I really liked that it was synchronized with the calendar that is included by default in Ubuntu (and which is accessed from the bar at the top of the Desktop): Everything you put in Evolution is automatically put in the Ubuntu calendar, and vice versa. Great when you want to quickly access this kind of information.

Right now I'm investigating Thunderbird. So I already have the email client (not yet tested, but investigated in terms of settings, etc., etc.). For this I now need the other mentioned parts (especially calendar and To-do) – and get them to work as described above.

Since there are such a lot of add-ons/extensions for Thunderbird, I find it quite difficult to navigate and confusing to find out exactly which add-ons/ extensions could correspond to the expectations/requirements I have for those, which I hope to be able to get help with here.

Regarding the calendar, the searches I have conducted several times have suggested the extension "Lighting" (https://www-archive.mozilla.org/projects/calendar/lightning/download), but based on the information I have obtained so far, I am unsure/doubtful whether this extension (which, if I understand the matter correctly, is in principle equivalent to the stand-alone application "Sunbird") will meet the criteria I have listed above. Especially when it comes to the Task function.

So the question is: Which extensions, corresponding to my wishes/requirements, should I choose in terms of calendar, To-do, and address book?

Or are my criteria such that there are no such corresponding add-ons/extensions at all?

Or is it better to download some other version of Thunderbird where all of these are pre-installed (and which meets my criteria)?

Looking forward to any answers that may provide some clarity. :)

when printing a PDF in two side mode, the text is moved to one side, I assume to allow for binding the pages. However this function does not work correctly as some pages have the text moved to the incorrect side. I had to use MS Edge to do the job which is something I do not like to do.

Three weeks ago I attempted to migrate my TB profiles from a 2014 mini-mac to a 2024 mini-mac. I thought I did a better job of backing up my profile using CCC than I actually did. In the migration to the new Mac I lost all my subfolders from the last 20 years. Apple created a new Profile and 2 restoration Profiles on the new Sequoia based mini-mac. I wasn't familiar with these and panicked. I copied those files, took them back to the original mac and tried to follow Toad-Hall's method of restoring the subfolders recommended to bmack1 on 23/11/22. However, I failed to carry out the step of going up two levels in the path of the Library to copy the entire "Thunderbird" file and only copied the Largest restoration file. This in turn, "contaminated" the 2014 original Thunderbird mail profile and only an Inbox and Trash subfolder remained. Today, after 3 weeks of searching and reading the generous contributions of this community, I came across a post explaining that the "sbd files" will show the subfolder headings I created in the original sought after Profile. And I found it!!! My problem is I have re-read Toad-Hall's method of re-installing the original Profile and tried to carry that out to the letter by placing the old Profile within a Thunderbird folder and switching it with the current one. But it's still listed as the "Restoration qqg...file" and probably shouldn't be, but I don't want to go any further and risk losing it because I feel I almost have it. So any guidance would be greatly appreciated. Thank You.

Hello, thanks for any help.

I am trying to initiate a Mozilla scan on my iPhone, where Firefox is installed. iOS is 18.7.2.

I begin my login to my Mozilla account, and then in the next window, Firefox (correctly) calls for my 6 digit code from my Authenticator.

BUT, when I "leave" the Firefox page, to go fetch the code, Firefox keeps opening a new webpage, and I lose the page where I would enter the 6 digit code.

I had the WSJ.com as my homepage, and changed this back to the Firefox homepage. This did not solve the problem

I'm exhausted. I'm not a techie, but not a newbie either (after many years).

Every couple of days, I have a day when Firefox tabs keep crashing. Today, for instance! Here's my latest collection of crash reports:

bp-fcc4cd08-d5c2-457b-a71a-1c3b70251123 bp-fcc4cd08-d5c2-457b-a71a-1c3b70251123 bp-992abd92-98f7-4371-85b2-2692d0251123 bp-992abd92-98f7-4371-85b2-2692d0251123 bp-a46d51fe-b360-449b-8b38-897eb0251123 bp-a46d51fe-b360-449b-8b38-897eb0251123 bp-762aaca2-94ea-4522-862e-a37000251123 bp-762aaca2-94ea-4522-862e-a37000251123 bp-63c6b36b-4a65-463a-8ac4-4a6840251123 bp-63c6b36b-4a65-463a-8ac4-4a6840251123

Help me, Obi-Wan

The AI tab thing is a problem for me for multiple reasons. I found various articles about how to turn it off. They pointed to the following setting: In about:config set the setting "browser.tabs.groups.smart.enabled" to false, and then restart Firefox.

However, when I do that, and then immediately go back to about:Config to check the setting, it has changed itself back to "true".

Other settings accept and keep permanent changes. This means that I'm not forgetting to save the change or anything. Just this one setting (which turns off something causing me problems) refuses to actually stay set.

I see the answer to this question https://support.mozilla.org/en-US/questions/1509077 and tried looking there. There is a completed study called "Smart Tab Groups Rollout", but since it is in the "Completed Studies" group, I cannot remove it.

So Outlook is refusing to let me right click and past again. I thought i solved this problem a few years ago by setting dom.events.asyncClipboard.clipboardItem dom.events.asyncClipboard.readText dom.events.testing.asyncClipboard to True in about:config. And sure enough those settings are still set to True so why is Outlook now telling me it can't access my clipboard again?

The blue bar with the option to undo a tab close isn’t showing anymore, and it was really convenient when I accidentally swipe and delete a tab. Now I have to go back to my history and look for the tab I deleted, which is really annoying. Is there any way to bring it back?

Hello, When I first built this Linux Mint laptop I just grabbed the first Thunderbird install I saw, never realizing it would never update, now understaning how this works I want to install the flatpack version so I can be up to date. what is the best way to attack this, can I just install the flatpack and it will capture all my mailbox settings or do I need to start from scratch?

Thanks in advance Guy

Just wondering why our forum posts can't also be black on black, or white on white, etc? Seems like the forum is stuck in the past, still doing the old black on white, as if anyone cares about being able to see the text.

Drag and Drop attachments to the desktop stopped working again with Thunderbird 145. Steps to reproduce: You receive a mail with an attachment. You drag an attached file from this message and drop it onto the desktop of your Mac to download it. The attached file is not saved to the desktop (or any other folder I tried). This is on MacOS 26.1 MacMini M4. Please fix asap.

Am having an issue with creating a “new folder” in my inbox. I create the folder, shut Thunderbird down, re-open it and the folder is not there. Did this three times, same result. A

lso, having an issue with tagging. I will click on an email, right click, and nothing happens. I have to click on another email, click the original email, then I can tag it. I suspect a corrupted profile but, not sure. Any ideas?

One annoying feature of Firefox is that during a print process, if the web page contains an iframe and that iframe utilizes a different domain name than the original page, Firefox will not print the data contained in the iframe. As a long time Firefox user, I would suggest that if I can see the data, then Firefox should print that data. Perhaps there might be some sort of security concerns involved, however at least give me an option to override it for certain domains. I do note that MS Edge does support the printing of iframes. The issue can be easily recreated on most eBay pages that list an item for sale. The 'Item description from the seller' data is contained in an iframe and does not print in Firefox.
