Recently I have noticed some changes in the way my Thunderbird downloads POP3 messages. Previously, it would be common to ask for new messages once a day and receive upwards of one hundred of them. But in the last month, this number has been limited to about 35 at a time. If I ask immediately again, I get about 35 more, and this pattern continues as long as there are messages in queue waiting to be downloaded. I am not sure if this is due to changes in gmail, where most of my received messages originate, or to changes in Thunderbird itself, or to some sort of third-party hack. Now that I have trained myself to keep on asking until there are no more messages coming down, this change does not cause me much difficulty, although initially it sometimes caused me to overlook messages because I failed to keep asking as long as I should have. Apart from that, it does not seem to be harmful as far as I can tell. I'd just like to know if other people have noticed anything similar, and if anyone knows what is causing it, and whether it has some hidden advantages over the way things used to work.

My Tags window & folder [View, Folders, Tags] layout stopped properly displaying all my items with the appropriate "tag" set in the past few updates to T'bird. I recently switched to version 140.4.0esr but the problem existed before that in 140.2.1 as well. Is there any way to force a "rebuild" of the Tags window so that all my tagged items show in their appropriate categories, with appropriate statuses [read/unread, etc]? Otherwise, the Tag feature is no longer useful.

Dear Support, when I forward a message, it gets successfully forwarded to the recipient, but the forwarding message itself is lost -- it's not in the Inbox folder, and not in the Sent folder.

The only indication is a forwarding icon in the forwarded message.

My settings are attached. I'm using IMAP with FastMail. I checked the Web interface and don't see the forwarding message there either.

I also tried selecting the `Sent Items` folder manually in the settings, no difference.

Here's a slightly trimmed `MOZ_LOG="IMAP:5,timestamp"` output https://gist.github.com/igrekster/f694698e4033637f2dd5d6202d99341d

Thanks!

An e-banking site that worked in Firefox for years no longer works in 145.0 under Ubuntu Studio 24.04.1 This is the help page for the error I am receiving: https://support.mozilla.org/1/firefox/145.0/WINNT/en-US/connection-not-secure However, the error message I received (see attached image) is not listed there. Since the e-banking site hasn't changed in ages, I suspect instead something in one of the recent Firefox updates. The site works fine in Safari under Sequoia 15.5 on a MacBook Air, and I can login in Firefox, so I doubt that there is a problem with the site's security certificate. Since both the MacBook Air and the Ubuntu PC are on the same LAN, I also doubt any network obstruction. I haven't found a wax to get any more detailed error information and would be grateful for tips on how to do so. Meanwhile, I would like to at least change from the standart Firefox release to the ESR veersion, but find no information on how to do so. I have currently set up Firefox to be pulled from the instructions in https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended under "For Debian Trixie and Newer" How can I switch from my current Firefox under Ubuntu to an ESR release?

two images. first image, the email that I SENT TO MYSELF, from my android phone, captured a product link, sent the link to me, and opened it on my desktop (or even opened on teh phone) and the HTTP link does NOT indicate it can be open,and if i hover over it, it does not open either.

BUT, if I FORWARD that same email to me (opened on desktop, forwarded to my email, and opened on desktop), it ALLOWS me to open it. why are the links not working if i send myself an email from my phone (where i browse products, etc, and caputere the links)? any assistance appreciated, thanks

Hey

Thunderbird has a well-functioning Search function that uses the cache (or rather, what the background search process/function "read" and saved in global-messages-db.sqlite).

With a newly configured account (IMAP), it works like this:

- establishes the directory tree - downloads message titles (including sender, date, etc.) - *.msf summary files - then a process that downloads the entire message for local storage - in the background, an indexing process (GLODA?) starts, which creates a search database (subject, from, to, keywords in the message body) using the global-messages-db.sqlite file.

For very large mailboxes (>100k msg, ~50GB), this means that the server's content is transferred to the local disk (and stored in ImapMail).

The question is: how do I configure TB to run in "thin" mode, meaning after connecting a new account: - establish a directory tree - download message titles (including sender, date, etc.) -> *.msf - DO NOT download messages for local storage - start the indexing process, which will download and index the subject, from, to, and keywords in the message body (it will download and "read" the message, but not save it locally) and save it to global-messages-db.sqlite

Setting "mail.server.default.offline_download" to "false" will cause this behavior, but the message body will not be indexed (only from, to, and subject).

I tried to work around this by: - configuring the mailbox with the download option for offline use - waiting for it to download - setting "mail.server.default.offline_download" to "false" - deleting all "cur" directories (I use maildir) or deleting all *.eml files from the ImapMail directory.

Content search works for messages that have been downloaded (and indexed) previously; it doesn't work for new messages.

Why am I trying this? Some people have "air" laptops (meaning - weaker processors, small SSDs) and need access to email (via IMAP), including full search, without having all their email downloaded locally.

In other words, how can I configure TB via IMAP to: - download the directory and subdirectory tree - download the headers of all messages - "read" and index all messages (including their content) and store them in "global-messages-db.sqlite," but not store all messages locally (online mode only)?

About a week ago, my Firefox browser started being extremely slow to load. It loaded the shortcuts but the page full of news things to click on never loaded. Instead, the rectangles where they would go were just illuminated from left to right with a gray sweep light to dark over and over. I left it going and hours later it was still doing it. I clicked on some of the shortcuts and some came up and others did not, at least during the time I was willing to wait. I went to Google Chrome and it was slower than usual but eventually I was able to get to my email, ebay, etc. I spent hours on the phone with Xfinity/Comcast and they ran tests and said everything was ok. I checked and found that I have the latest version of Firefox. Is it possible that an update caused this? If not, what is going on?

WHY is Firefox.exe file FORCED onto my desktop???

I do NOT want it there and if I move it, Firefox will not work.

It's bad enough to be inundated with spyware AI being forced upon us everywhere but for Mozilla to decide to FORCE FIREFOX ONTO MY DESKTOP WITHOUT MY PERMISSION is insulting and an invasion of my laptop.

I do NOT NEED MOZILLA to make decisions about my "ease of use."

I AM NOT HAPPY. I feel that I CANNOT TRUST FIREFOX AND MOZILLA like I used to be able to.

Please remove this aggression and restore the ability to CHOOSE WHERE AND HOW I LAUNCH FIREFOX.

Thank you.

Fedora 42 x86_64, firefox 145.0

Using FontForge, I created a custom Unicode (NO 8-bit pi encoded) version of the Symbol typeface with a new font-family name.

One of the customizations, the serif versions of the "Registered Sign", "Copyright Sign", and "Trademark Sign" are available by the official Unicode codepoint. The sans-serif versions are available by the official Unicode codepoint *directly* followed by U+200B (Zero Width Space - ZWSP).

This is done with the OpenType contextual alternative feature (calt).

It works in the FontForge metrics test window and it works in Chromium and derivatives but it does not work in FireFox - either the Fedora 42 build or the generic x86_64 build from Mozilla.

I tried the CSS setting:

body { font-feature-settings: "calt" on; }

No dice. I believe that's the right CSS setting because if I change the "on" to "off" then it no longer works in chromium and derivatives, so that does seem to the be the CSS setting that controls whether or not the feature is enabled.

All my searches on the web seem to indicate the FireFox supports calt however all the examples I see are related to swashes which are enabled/disabled by a different CSS setting.

I did see some indication that some apps only allow calt for certain language scripts, typically Arabic and/or Greek and/or Latin and perhaps these legal glyphs aren't considered one of those scripts?

Does anyone know why the calt works elsewhere and not in FireFox? Yes, I tried without any extensions or plugins enabled.

Over the past few weeks, emails have suddenly started migrating from my inbox into my trash. I can put them back into my inbox easily enough but it's really annoying.

The interesting thing about these emails is that, when they go into the trash folder, they stay there. I have my Thunderbird settings so that any emails I actually delete don't go into the trash but simply disappear.

Can anybody explain why this is happening and how I can stop it?

Thank you

I believe I had all this synced in Firefox Settings before I made the upgrade. Like all you fellow former users of Windows 10, I had to upgrade to Windows 11; and did so two days ago. Now, I found that I do not have under History any of the former sites I not only visited but also had tabs open. What can I do, if anything, to recover them? Under the Add-ons Manager, if this helps, I already had the app Tab Session Manager, but don't know how to use it. Thanks to all in advance who may have made this same upgrade. Many out there are still on Windows 10.

I see no x on tabs to close; I see no "close tab" option in the menu when I right-click on a tab; I see no close tab option in main menu.

1. How do I get the close tab button to show on a tab?

2. How do I close all tabs?

3. Where do I find a close tab command on menu?

4. How can I get to automatically close all tabs on closing?

5. Are there other ways of closing a tab?

Thanks.
