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

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'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

Thunderbird Extension API Returning Stale Cached Data for Gmail IMAP Folders

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… (read more)

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 to completely remove Okta authentication automatic redirects from Firefox

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.

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

I am used to having a Firefox for my personal Mozilla account, bookmarks and sessions, and Firefox Developer Edition to be logged in my work account, where I could use everything I need to work in a separate environment.

Recently I changed a job. Logged out past-job@mail.com from Firefox Developer Edition, logged in with present-job@mail.com and... I still can see old bookmarks.

- I cleared history and new bookmarks: nothing
- went to about:preferences#privacy and clear all the data: bookmarks still there
- tried Help > More troubleshooting information > Refresh Firefox…: all the same
- reinstalled firefox@developer-edition with brew: nah
- eventually, logged out from presetn-job@mail.com in Firefox Developer Edition and personal@mail.com in Firefox; uninstalled both, deleted everything related to "mozilla" and "firefox" was able to find in my system: unsuccessfully

The last thing I didn't try yet is burning my laptop in favor to a new one.

Where are those bookmarks? Why nothing is helping?
