Hi, Thunderbird : Under Windows 10 and Ubuntu, I have a vertical taskbar on the left. but once installed under Widows 11 no taskbar and no way to make it appear. Do you know a solution? Thank you

I noticed that I can't see the end of any longer email messages and realized that the Status bar is missing in the email window, too. Changing the relevant setting in the menu didn't do anything. The Status bar is visible in other tabs. When I hid the Today Pane (Events & Tasks), the status bar came back. When I displayed it, Status bar disappeared again. With longer email messages, it is impossible to view the complete message, because the message window seems to extend below the screen bottom. Hiding Windows task bar doesn't help.

Help, how can I have my status bar and read the messages without opening them in a new window, without having to hide the Today pane?

I have an MS email account which is passwordless and only uses fingerprint/passkey authentication.

How do I get TB to use this security method to gain access to my email? Currently, every time I try to add the email address/account, it asks for a password, which obviously I don't have.

Please excuse misspellings and anything that may not make sense or cause offence as the medication I take can have an adverse effect on my mind.

My bookmarks toolbar is showing, but it's empty. All of my bookmarks are gone.

I went to a websites and attempted to add it to my bookmarks toolbar, but Firefox failed to add it to my toolbar.

I'm on Windows 11, I've archived my gmails to a 3GB zip and extracted it to a local MBOX file. I want to sue Thunderbird only to be able to conveniently see these emails. I don't want any accounts, nor to connect Thunderbird to the internet - I juust want to see the gmails.

I've installed Thunderbird, and the import/export Tools NG add-on. It won't let me import to a unified folder, so I deleted the unified folder. I have no "local folders", so I can't right click on one and select import. I can't see how to make one either, and the help is of no help.

I wonder if somebody could tell me, without assuming knowledge I don't have, how to do this please.

Thanks Chris

Hi I have a firefox account which I use on 2 macs and a PC as well as an android phone. For the past few months non of my book marks, passwords etc are being synced across the system and I have now completely different book marks on different devises. I have synced each computer multiple times without effect. This used to work perfectly before I changed my password a few months back. It is now reaching a point that firefox is no longer usable for me?? Thanks for your help

When I open the tab tray and realize that I don't know where the tab I'm looking for is, I would like to be able to type some search terms to find it.

This is when I am searching for a tab that I know is open, so I'm not using the new tab workflow.

I am having trouble with my Midflorida bank loading information. I am using my desk top and it goes to a page that states I am using an app. Please help me.

Thank you

Yesterday while using Firefox my keyboard quit functioning in Firefox (Windows 11). I closed everything and restarted the computer. Everything else works fine, but Firefox would not load. I tried to the repair function and that wouldn't load. I tried to uninstall and that wouldn't load. I uninstalled with a third part app, and tried to reinstall, but that keeps giving a can't install message after trying for several minutes. I tried to install Firefox Beta and that installer hangs up at [Execute: "C:\Program Files\Mozilla Firefox\default-browser-agent.exe" register-task 308046]. Also cleaned registry.

I'm having trouble installing Norton Password Manager, I keep getting a corrupt file, won't install, so I am running through the checklist of possible fixes.

The one I am up to is this :-

Refresh Firefox Click the menu button (≡). Select Help, then choose More troubleshooting information. Click the Refresh Firefox… button on the right side of the page. In the confirmation window that appears, click Refresh Firefox. Firefox will close and restart. When it finishes, a window will show the data that was imported. Click Finish. Choose whether to restore your previous windows and tabs, then click Let’s go!.

I cannot find the "Refresh"

I've run Troubleshoot Mode

I have cleared the startup cache, problem not fixed.

My cat laid too close to my keyboard (i.e., by the control, shift, and windows button) and I am now unable to send messages from any of my email address in Thunderbird. I've checked the server settings and they all appear to be correct, but I keep getting the error message that connecting to the smtp failed. I'm receiving emails, but can't send them. Is there anything else that I might be missing apart from checking the server settings.

Hi I am using thunderbird with the integrated events connected to various google domains. My calendar looks synchronized and notifications show up. I am on popos on a laptop. The thing is that a lot of time the notifications show up late; like not hours late, but let's say 5 minutes late and sometimes they don't re-appear after the initial reminder. So it's not 100% sure that you will get reminded or pinged at the right time. I have not figured out any specific rule when it works and when it won't. Curious if anyone else is running into such problems. Thanks Andreas

Dear Thunderbird Team,

I am writing to report a critical issue with the Thunderbird Extension API where it returns stale, cached data instead of live folder contents for Gmail IMAP accounts.

Issue Description The browser.messages.list() and browser.messages.query() APIs are returning outdated message data from 2016-2021, completely ignoring the actual current contents of my Gmail IMAP inbox. While Thunderbird's UI displays current emails correctly, the extension API serves permanently cached old data.

Evidence of the Bug What Thunderbird UI Shows: Current inbox with emails from today and recent weeks

Real-time folder contents

Proper folder synchronization

What Extension API Returns: Only 100 messages total (artificial limit)

Messages exclusively from 2016-2021

No emails from 2022-2025 present

Completely ignores current folder contents

Technical Details: Profile: /Volumes/Data/Mail Files/Thunderbird/Profiles/aq8q4la7.default-release/

Account: Gmail IMAP (imap.googlemail.com)

Folder: account1://INBOX

API Used: browser.messages.list(folderId) and browser.messages.query()

Steps to Reproduce Set up Gmail IMAP account in Thunderbird

Write extension using browser.messages.list() API

Compare API results with actual folder contents

Observe API returns stale cached data from years ago

Debugging Attempted We have tried:

Deleting all .msf index files

Clearing folderCache.json and global-messages-db.sqlite

Removing cache folders (cache/, cache2/, startupCache/)

Rebuilding folder indexes

Using different API methods (messages.query vs messages.list)

None of these resolved the issue - the API continues to return the same stale dataset.

Impact This completely breaks any extension that needs to access current folder contents, such as email tracking, automation, or filtering extensions.

Request Please investigate why the Extension API serves different (and outdated) data compared to Thunderbird's main UI, and fix the API to return actual live folder contents.

Thank you for your attention to this critical issue.

Best regards, Hasan

How and where do I report when immersive reader mode renders a page incorrectly? What are the rules governing immersive reader mode inclusion?

An example is : Britain prepares NHS drug spending hike to stave off Trump tariffs

Phone: Nothing 3(a) Headphones: Nothing ear (a) When using YouTube (phone speaker) all runs smoothly. But when using earphones videos desync and stutter very badly. My extensions are "ublock origin" and "privacy badger" Any help or suggestions would be welcome

I am an academic researcher formerly affiliated with an institution that uses Okta as its two-factor authentication service for access to institutional subscriptions (think Elsevier, Cambridge Core, Brill, JStor, etc.). Since I am no longer affiliated with that institution, I am no longer authorized to access that institution's subscriptions. I am not trying to access that institution's subscriptions, however, if I try to log in to these repositories as an individual, I am automatically redirected to my former institution's Okta authentication page.

The browser: Mozilla Firefox 143.0.3. I am able to access other sites on other browsers, as well as in private Firefox windows, which suggests it is a problem with my Firefox account. These are temporary workarounds I can live with only in the very short term. I am under no circumstances willing to switch browsers. I use Firefox for a reason. FWIW, I am also contacting Okta support to see what they recommend.

The computer: Macbook Air 2020 M1. It is a personal computer. I do not have access to another device.

I have cleared my browser history, saved form data, saved site settings, cookies, and cache (x5). I have deleted all saved passwords containing the email address associated with my former institution. I have restarted the browser (x5). I have restarted my computer (x2). I have reached out to IT at the institution (they are flummoxed).

I'm nearing my wit's end with this. I'm working on multiple projects with multiple deadlines. The temporary workaround and constant barrier to access are driving me up the wall. I will be infinitely grateful for a permanent solution to this hellish problem.

Yesterday I upgraded my PC from Windows 10 to 11. Today I discovered my Local Folders are not visible. Searching tells me the messages still exist, but TB does not show the folders. I did the same upgrade a month ago on a laptop (Windows 10 Pro to 11), no problems. I didn't externally back up the messages as I am a dinosaur and don't know how, but at least they are still on the hard drive. Thousands of them though so I need the local folders back. Tried all the fixes I can find on the Community Forum, without success. Can anyone help please? Bob

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks
