Went to search for someone in the Quick Search and it did not bring up their emails in the folder, which exist as I confirmed by sorting alphabetically and finding them. Why is this?

Whenever I try to search my various emails for some text, at least 40% of the time it shows me the attached message. I'm on Version 149.0.1 but it's been happening ever since I installed Thunderbird (maybe 4 or 5 months ago?) My first move is to check that I haven't mis-spelled the word I'm looking for (which I usually haven't) and I definitely know that the word is valid for one or more emails. So why does this message keep appearing?

Previously I'd been running an old 32-bit version of Thunderbird (which I don't have installed any more) but I don't remember ever seeing this with the older version.

Hi,

I do like Thunderbird but there are a couple of things that i'm finding it frustrating to work with and wondered if someone could provide some help?

So I use quite a lot of nested folders, sometimes up to 5 levels deep to keep things organised. Eg:

I a sub folder structure like so:

Trips - -Asia 2025 - - - -Hotels - - - -Flights - - - - - -International - - - - - -Domestic - - - -Parks - - - - - -Park 1 - - - - - -Park 2 - - - - - -Park 3 - -Europe 2025 - - - -Parks - - - - - -Park 1 - - - - - -Park 2

I'd like to be able to be able to select a top level folder (such as Asia 2025) and see all the messages in it and all it's subfolders. Effectively ALL the emails relating to the trip. Is there a way to achieve this?

Second issue: I have a saved search folder called Flagged. Right now I have to edit the properties of the saved search, then click "Choose" and manually tick each folder / sub folder I wish to show flagged messages for. I know I can select the first, select the last, press spacebar to toggle those folders. But it doesn't expand subfolders, and it means that when I add more folders (which I do very very often), I have to remember to manually update the list of selected folders (on 2 machines too as i have this account set up in 2 places). Is there a way to just select a parent folder (in my case i'd like to just select the account itself) and have it automatically include everything below that. Then I don;t need to update or change it as my folders change.

Surely both of these suggestions are sensible and would increase the usability of Thunderbird.

Also, how can I find out what folder a message is stored in from the message in cards view, the message detail panel itself or the right click menu of the message card?

Thanks, Neil

I have an issue with search on version 144.1 (iPadOS 26.0.1 and iOS 18.7.1), where my default search engine selection (Kagi) in Firefox's settings are not respected, and will randomly change if I enter a search term in the address bar.

Often times, when performing a search in Thunderbird, the pointer in the message index (ie: your INBOX) will be updated downward (if you have a lot of messages, like I do). You have to manually scroll back to the top after -- but would it make sense to just have a button that does this, that brings your pointer back to message 1 in the view index (however you have it sorted) and updates the view accordingly?

Basically, press the button and you're back to the beginning of the message index.

Hi, Thunderbird search as we know is and always has been megabroken. I search for "4.91" and it does not find anything even though there are e-mails with that string in subject and body.

Isn't it about time to fix it?

The latest version of Firefox won’t save my custom search engine as the default. When I force close the app, it goes back to DuckDuckGo.

iOS 26.1 Latest version of Firefox.

Recently, when I copy and paste an error message to the search box in Firefox and the first word contains a ':', such as when searching for this error message - "MESA-LOADER: failed to open dri: /usr/lib/x86_64-linux-gnu/gbm/dri_gbm.so: cannot open shared object file" - I get the "Open the mesa-loader link with System Handler?" prompt (see screenshot).

I used to be able to copy and paste such an error before into the search box and it would just work but now the browser defaults to thinking you are entering a URL. This could be because when I start typing in the search box, it immediately relocates what I'm typing to the address bar. Maybe this is the behaviour I need to disable? But how and why is it the default?

Help!

Would like to see these enhancements made to Thunderbird:

1. Add recipient email address to view. This could be added next to the sender email address, separated by something like a pipe character "|" and identified by "From: ", "F: ", "Sender: ", or "S: " in front of the sender address and "To: ", "T: ", "Recipient: ", or "R: " in front of the recipient address
2. Add search filter terms to search capability. Some example filter terms would be 1) "mailed-to:" or "recipient" to search for emails sent to a specific email address or domain (using wildcard), 2) "mailed-from" or "sender" to search for emails sent from a specific email address or domain (using wildcard).

I do not want to search from the address bar. The search bar is what I want to go to but invariably goes to the address bar. Is there an about:config setting to change this?

As a loyal and long time user of Firefox [since 1998 yes 1998 ,,,] if you or i cant remove google from my browser , i might have to find a replacement, that will allow me to remove this nonsense , i await your response ATB BlackSam

On doing a search for mail ... it returns a number of mails ..... but many of them when I click on the entry it comes up with 'no message found'

Is there some index I need to rebuild or similar ?

I feel so incompetent regarding this because I feel it should JUST WORK, but for me it just doesnt...

When searching for a name/date/etc in the top right search bar I typically get no result or unusable ones. Obviously this is a problem when I dont know where a particular email may be.

When I use the search messages window from my root folder, the one that gives more flexibility ie; match any, subject,contains, etc...i also get no results. For example a message that is currently an open tab in TB cant be found by that search messages window. its still searching and i began the search before I started writing this question...

When in a folder or sub-folder, the quick filter search feature works as expected.

I've checked all the places i could imagine that might govern global search options that might change this critical seeming lack of functionality and have found none.

Is this a true limitation or am I just missing something ?

thanks for your consideration- q

Why is the address bar now a search? This is annoying. How can I change this? I have already change about:config settings to false and nothing changes.

Thank you Rafal

For the last couple of weeks my default search engine keeps changing. Even though I change it in the setting to the one prefer eventually it changes. Why is this issue happening and is there anyway to force my preferred search engine as a constant default?

When I reconcile my checking account each month, it's handy to be able to search my e-mail for the amounts of transactions that I can't identify by name alone. Gmail allowed me to do this. Thunderbird, for some reason, doesn't. Anytime I search for a numerical value (e.g., "36" or "9.58"), Thunderbird returns no results. Why are numeric strings not searchable? Is anyone working on this deficiency?
