Hello,

I *can* resize the folder pane in the first/main folder tab, but, I *can not* resize the folder pane in subsequent folder tabs I create using "open in new tab". 

This occurs using any layout (Classic, wide, vertical view). In the first tab I get the double-headed arrow to resize the folder pane, but in subsequent folder tabs I don't get it.

When I open a  folder in a new tab, the folder pane is the same width as the parent tab, but, I can't adjust it.

I'm using Thunderbird 152.0.1, but, this has been going on for a long time from what I can remember.

I've tried a number of suggested things to fix this: - Deleted xulstore.json - Cleared Startup Cache. - restarted in Troubleshoot mode (and I get the same issue there). - Switched layout views - Toggled folder modes - Adjusted interface density. - Toggled hardware acceleration. - Deleted the UI Cache Folder (shader-cache)

Nothing worked.

Please help me with this!

Thank you, Jim

Hi,

I use AltSnap and its snap feature a lot because I have multiple 40" TVs as monitors.

That means I often deal with thunderbird floating windows rather than maximized, and I often resize it.

And I notice that my message list is always getting too small !

I realized this is because when you resize the thunderbird window vertically, the preview pane stays a constant size, but it is the message list that resizes.

Over time the message list gets squished out and not even one message is visible.

I think if the message list remained of a constant size during vertical resize and it was the preview pane that got resized along with the window, it would prevent that and the message list would always be, the size that you last set it.

In the email address tree on the start up page of Thunderbird, how can I manually sort the email address order? I have an address I would like to move to the top of the list.

I know it can be done, but I can not for the life of me remember how. Please help.....

I've read a lot of suggestions on the FAQ section, but what they are offering, I do not have listed in/on my Thunderbird.

Thank you.

I have attached a screenshot of the retention settings for the Gmail All Mail folder. This folder contains emails that have a date nine years ago. Can you tell me if I did something wrong in the retention settings?

I thought earlier today it was using the retention settings but I just checked and it is not.

The new "Copy Link to Highlight" button shifted the "search with" option down, which I use regularly.

I'm not entirely sure what the new option does, but I would like to either disable it or shift it further down out of the way

I'd like my Inbox appearance to be as it was before I updated to Windows 11. I find emails with Threads very confusing and time consuming and slows my performance. I prefer the simplicity of original Inbox way of showing incoming mail and NO threading. Can you help please?

I have no desire to interact with Google, Bing, or Perplexity, and as a rule I don't want outside parties (such as Firefox/Mozilla) deciding for me which search engines or other service providers I see advertising for. (And yes, seeing that "G" logo somewhere is advertising for Google.) I'm assuming that these companies are paying to be pre-loaded as search providers in Firefox, and I understand that Firefox needs this financial support if it's going to continue providing a browser.

After upgrading, I've always gone into the settings and removed these search providers - I don't want to see them offered as search options, and to be honest, I don't even want to see their names in the settings screens.

Now with Firefox 152, I find that I'm not able to delete these pre-loaded search providers anymore. I can turn off a switch to disable them, but there's no way to totally delete them from the list anymore. There's even a [in the documentation] which explicitly says that the pre-loaded search providers cannot be removed, only hidden.

'WHY can I not delete them?

Is there a technical reason, i.e. would the browser stop working if they were removed? Are some companies paying extra to not be delete-able, and it just happens that every one that's pre-loaded in Firefox 152 decided to pay the extra money? Or did Mozilla just make an arbitrary decision to reduce the level of control that users have over their own browsers?

is it possible to make the cache bigger than the 1gb it has i have spent hours trawling though the data and cannot find it please help a 70 yr old even ifs a no cannot be done

many thanks

On my Samsung A05 Thunderbird does not show received email dates only the day. This is useless for finding emails going back more than a week or two. I don't care what day of the week it was received, just the date and time. Earlier solution offered (via message lists) not in any of my menus so cannot use. Please advise how to show dates. Current OS Android 15 A055FXXSHDZF1/ A055FOJMHDZF1 / A055FXXSHDZF1 with security patch level: 5 June 2026 Also cannot find support/about option in the settings menu to show the Thunderbird version.

Please add an UNDO feature to the Android version.

It has happened to me multiple times that when trying to scroll (esp in the bus) it registers as a swipe & deletes a message.

and then it's really hard to scan the trash to figure out which message it was

at the same time, i don't want to be asked for confirmation *every* time i delete something - I'll spend as much time "confirming" as deleting messages.

So the ideal in an undo button somewhere in the interface where a can undo the last action (from a subset, since I'm guessing not every action can be undone). The desktop version has it, hopefully it can be migrated to the android version.

thank you

When incoming email arrives a notification sound is heard on the phone which is fine. But when connected to Android Auto the notification sound is not heard nigher on the phone or through the car speakers. Other apps on the phone such as Signal and WhatsApp do play the notification while connected to Android Auto so it's not an Android Auto setting that's the issue. Why would the notification play fine on the phone but not while connected to Android Auto while other apps do?
