In Thunderbird on my Mac there appears to be no way of restoring alphabetical order to Folders.

All of my folders under A(and there are a lot of them) have dropped down a few alphabetical letters. There is supposed to be a right click on account name and restore this order, however, like many features on Thunderbird it does not exist now.

So a) why has Thunderbird on my Mac done this and how do I sort it out please?

Hello,

Based on this previous post https://support.mozilla.org/en-US/questions/1195138

I have turned off mousebutton.4th.enabled and mousebutton.5th.enabled

But I wish to bind these buttons to previous tab / next tab How can I accomplish this ? Thanks

Hi,

I've just updated my Thunderbird for Windows to 151 and I got this nasty surprise (this is why I hate updates these days).

The message list in dark mode, in a table view, now has this awful pitch black background instead of the normal dark brown as it used to have. It looks OK in cards mode, but I don't like cards mode.

I certainly hope this is a bug and not by design. Can this be fixed, please? It looks terrible, it's hard to look at, like old Windows 10 dark mode or some high contrast accessibility mode.

Thank you!

Firefox opens on my second monitor despite my confirming my primary monitor as 1 in Windows 11 I have tried on many occasions to "lock" Firefox onto monitor 1 via settings in Win 11 and Firefox, but it still opens probably 3 times out of 5 on the 2nd monitor. My version is 151.0.3

My mouse is setup so that the tilt wheel does Ctrl+Tab and Ctrl+Shift+Tab rather then whatever actions the tilt wheel would normally send, and that has worked fine for years, but now all of a sudden it is not working in Firefox, it's changing the zoom level instead which is not what I want. Firefox must be reading the mouse directly or something, because it shouldn't even be getting normal tilt wheel events.

I am using Kubuntu 26.04 and I am using the monthly stable channel version of the Thunderbird Snap. In KDE system settings, the default email client is set to Thunderbird. Upon every startup of Thunderbird, it ask if I want to set it as the default client for email, newsgroups, feeds and calendar and when I click yes and close Thunderbird and reopen it it does the same thing, over and over. Otherwise the email program operates just fine otherwise. My email accounts are all setup properly and functioning and working and it downloads email just fine. It just has that annoying popup upon every startup. I've included two images to show what I mean. I like the Snap version and prefer that container format. I would like someone who is smarter than me to file a bug on my behalf.

I use vertical view. Hate threading so that's turned off. I use a medium to large message pane. Recently been having issues with column visibility. Not sure if this is new or whether it's that I've come to a Linux client from a Windows one and there's a setting I missed when I set up the client.

Essentially dragging the column divider doesn't work properly (for me). The columns always seem to auto adjust width. Similarly if I resize the message pane the columns don't remain fixed they auto adjust.

I don't find this helpful. I prefer to set up the columns to display the amount I want/need in subject and From and I truncate the date to simply not display time.

How do I set column widths to remain where I put them? Or is this function now lost.

Subject: Persistent Column and Folder Layout Issues — Not Being Saved Between Sessions

This is a follow-up to my previous support requests regarding two ongoing problems that significantly impact daily usability.

Column Settings I manage multiple accounts, and my preferred column layout is: Starred, Read Status, Attachment, Subject, From, and Date/Time. I do not use Threads, Correspondents, or Spam Status columns. Despite setting these preferences repeatedly, Thunderbird fails to retain them. Every day I must spend time reconfiguring columns across some or all of my accounts — the state varies unpredictably from one session to the next. This is a persistent, daily frustration that costs meaningful time. Most other major email clients save and reliably maintain column preferences. I'd expect Thunderbird to do the same.

Folder Panel Layout Two problems occur regularly when Thunderbird loads:

Folder order — Standard system folders (Inbox, Sent, Drafts, All Mail, Trash, Spam) should appear at the top of each account. Instead, Sent, All Mail, Trash, and/or Spam are frequently scattered among custom folders, with no apparent consistency.

Folder expansion — Most or all folders load in an expanded state, exposing every nested sub-folder regardless of whether they contain unread mail. This creates unnecessary visual clutter and requires manual collapsing each session.

Again, this behavior is uncommon in other widely-used email clients. Summary These are not one-time glitches — they recur daily and represent a significant usability gap. I'd appreciate confirmation that these are known issues being tracked, or guidance on a reliable fix. Reformatting the interface every morning is not a reasonable expectation for users.

Not sure if this is a Linux or Firefox issue, but here goes. In the past when uploading pictures for instance in Gmail I got a menu showing places EG pictures, video's etc. Example - home - pictures- cats - black cats - list of jpg's, click attach. When attaching another pic from the same folder etc it used to default to the same folder location with the list of jpg's.

With the last few FF updates that isn't the case any more, when next attaching a pic file I now have to start again from scratch EG home, pics, cats, black cats instead of click attach straight to list of jpg's in back cats.

Is there anyway I can configure FF back to the old setting please?

Hver gang jeg får mails i min indbakke så kræves det at jeg sletter dem ikke bare en gang, men to gange, før de væk fra indbakken. Tidligere har jeg kunnet slette en mail en enkelt gang - som i alle andre mailprogrammer - men nu skal jeg som sagt dobbelt - slette dem. Hvad kan jeg gøre for at annullere indstillinger om dobbelt - sletning. Kh Flemming

Can I lock in my Zoom setting to 120. When I am scrolling up or down a page, My 120 zoom goes crazy. There has to be a way to lock my zoom rate to 120. I can lock in my zoom rate with Chrome. Why not Mozilla?

Firefox has been automatically updated on Windows 11 and Tahoe, and now every time I close the browser, all tabs close – even the pinned ones – despite the ‘Open previous windows and tabs’ option being selected at startup.
