Hi, Hoping I can get some help here, I couldn't find an answer in the search topics.

I have lost a few local subfolders. First the subfolders lost the emails contained in them and then the subfolders themselves disappeared.

I renamed the main folder just removing the year from the folder name and not long after that the above happened.

I have tried the following:

• Searching the help topics • Searching the forum • Closing reopening Thunderbird • I removed .msf files and restarted Thunderbird

I am not sure what I can do now.

Thanks in advance for any help.

Environment

   • Firefox 153.0.1 (64-bit)
   • Ubuntu 24.04.4 LTS
   • Wayland session
   • Input method: IBus
   • Keyboard layouts:
       ◦ US
       ◦ Bulgarian (bg+bekl)
   • Graphics:
       ◦ AMD Radeon Graphics (renoir)
       ◦ WebRender (Software)

Summary When typing a multi-word search query in Bulgarian into the center search field on the Firefox New Tab page (about:newtab), the first word disappears immediately after pressing the Space key. The issue occurs only in the in-page search field. Typing exactly the same text in the Firefox address bar works correctly. Steps to reproduce

   1. Open a new tab (about:newtab).
   2. Click inside the center search field.
   3. Switch to the Bulgarian keyboard layout.
   4. Type the first word, for example:   български
   5. Press the Space key.

Actual result The first word disappears completely. The search field becomes empty and the caret remains after one blank space. Typing continues normally from the second word onward. Interestingly, pressing Ctrl+Z immediately restores the missing first word, indicating that Firefox performs an undoable edit operation rather than simply ignoring the input. Expected result The first word should remain in the search field after pressing Space. Additional observations

   • The problem does not occur when typing in the Firefox address bar.
   • The problem does not occur on google.com or in other web page input fields.
   • The problem is reproducible in:
       ◦ Troubleshoot Mode
       ◦ a brand new Firefox profile
   • No third-party extensions are installed (only the built-in OpenH264 codec is present).
   • Setting

browser.newtabpage.activity-stream.showSearch = false removes the in-page search field, therefore the issue disappears because the affected widget is no longer present.

   • Disabling

browser.search.suggest.enabled does not change the behaviour.

   • If the address bar already contains text before clicking into the New Tab search field, the issue may no longer reproduce. This suggests that the bug could be related to focus handling or interaction between the New Tab search widget and the address bar.

Reproducibility Always reproducible on this system. Notes The issue appears to be specific to the Firefox New Tab search widget (about:newtab) rather than to the operating system, keyboard layout, input method, or user profile. ____________________________________________________________ The text above was created following extensive discussion and numerous tests, in collaboration with ChatGPT.

My computer unexpectedly shut down when the power went out. When I try to open Mozilla Thunderbird, it doesn´t respond. Messages appear on the tabs at the top and a dot flashes on one. When I press anything, the text turns gray and the program doesn´t respond. I´ve turned off my computer many times, and that doesn´t help. I´ve also deleted a locked file according to the instructions. The situation is the same in Safe Mode, and it doesn´t help. What should I do now? Thank you!

MESSAGE:

“Your email ***.net and data has been hacked. . . . The Trojan virus gives me complete access and control over the device you are using. As a result, blah, blah, blah, blah . . . “

I rather doubt the veracity of this, seeing it includes “I can see the full list of your contacts from your phone and all your social networks” — since I do not access the Internet from any telephone.

It has been several years since I’ve received something of this sort, so have remained confident that my system(s) remain well-protected. However, since the message did arrive in one of my email accounts, is there still the potential of my contacts list(s) being compromised, and, if so, how to safeguard against that?

Many thanks. Appreciated.

I am trying to add a posteo email account to my thunderbird app on my phone and on my laptop. Each time when I get to inputting my user name and password I get an authentication error.

I'm moving from one PC (Windows 10) to another (Windows 11) and copied the Thunderbird folder over to the new PC yesterday. All seemed to be working fine on the new PC.

However, I've noticed that new emails sent to my gmail account FROM a gmail address are not being downloaded (I can see them in Gmail on the web). Emails sent from other addresses are downloading fine.

I have checked on the 'old' PC (which has identical configuration and is running the same version of Thunderbird) and they ARE downloading.

They aren't in the SPAM folder, I use POP3 and both PCs are configured to leave emails on the server, to it isn't that they are being deleted after downloading onto the old PC.

It's maddening, as about half my emails aren't available in Thunderbird, which makes it useless and I HATE native Gmail!

Thanks for any help anyone can provide

Pri vytvorení adresára v lište s odkazmi na web stránky sa adresár vytvorí na konci zoznamu. 1, nieje spôsob ako určiť poradie v zozname kde sú adresáre aj odkazy. Adresáre by sa mali automaticky radiť ako v stromovej štruktúre pc teda prve v poradí a za nimi voľné odkazy na weby. Adresáre majú nadradenú funkciu.Tvoria skupinu pre odkazy na stránky s podobným obsahom. Preto by mali byť pri vytvorení adresára radené na začiatok zoznamu a nie na konci. Pri 1000 odkazoch na stránky je to dlhý zoznam kým ho nájdem na konci aby som urobil drag and drop a preniesol na lištu z odkazmi do viditeľnej časti na browseri. Môže to niekto opraviť? Táto možnosť radenia adresárov nieje. Iba radenie odkazov podľa abecedy v zozname alebo iné možnosti na jednej úrovni pre všetky súbory. Ocenil by som radenie podľa typu teda adresáre spolu a odkazy spolu,či budú na začiatku alebo na konci teda poradie, a možnosť abecedného radenia pri zachovaní Typu súborov. Adresáre by mohli mať aj priradenú farbu. Ďakujem

After the most recent update to Thunderbird, I can no longer copy attached files on incoming emails to either my Quickbooks program or a folder on the hard drive by dragging over. Now must copy manually to drive. Can this be corrected?

Hello,

For some reason, when I try to sync all my stuff from my desktop Win 11 firefox/duckduckgo system, to my new Win 11 laptop, the only option I can get is to sync with a mobile device.

I had no trouble doing this some months ago with another laptop, but this time I cannot find how to do this after trying for over an hour . . . . . .

Has anything been changed that won't allow syncing with another 'big' device, please?

When I try to attach file via drag & drop, the Firefox always display "Download file" as attachment. I don't know why because it properly worked before. but after some updates, drag & drop is not working.

The version of Jira at my office is not changed for years(v8.12.1#812002-sha1:7c28d59) and drag & drop is working via Chrome, Edge and etc.

Firefox version: 153.0.4 / Windows 11 25H2 26200.9168

Attached are images showing the performance settings and the active extensions in case any of them proves to be responsible for the problem.

Yesterday I noticed a horizontal screen tear when scrolling down through sites like X(Twitter), YouTube, GMail, Reddit etc. I immediately checked my performance options and they were deselected. I activated them again, but this did not solve the problem, I also tried to active some layers in about:config but those were already activated. Checked Nvidia settings too, vsync is on, Edge is not affected, Chrome is not affected, even installed Waterfox to see if only Firefox-based browsers are affected, but that one was OK too.

Last resort was to refresh the Firefox installation from the uninstall utility. After the refresh and all settings/extensions got auto-reinstalled, the screen tear got fixed. I left the PC running over night and when I accessed Firefox again this morning, the screen tear problem was back. However, now, the performance options are disabled, and if I try to enable them and restart Firefox, the options get disabled again.

Would really appreciate it if anyone could provide a solution that does not involve refreshing Firefox daily.

Tonight when I launched Firefox, I started getting everything opening in a new window, rather than a new tab, which is what I have indicated in settings and have always had before. Even if I drag a tab from a new window to a previous window, I cannot close the tab. All I can do is close the window.

Hello! I am a user from Russia. Our Roskomnadzor blocks Firefox sync addresses. Unfortunately, this makes it difficult to synchronize browsers on different devices. Can you tell me how to get around this and keep the synchronization option?

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with ebanking.bankmellat.ir. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

ebanking.bankmellat.ir has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.
