Trying to get the mobil version to work. Can the mobil version coexist with the PC version? I tried leaving messages on server, but no joy. Got through the setup OK, but the mobile version want a signon to Google

I will preface this with no I do not have a backup - which is my fault. However I did not expect my account to be nuked into oblivion with no explanation.

As per the title, all my emails are gone. My local folders are devoid of anything I can use and am hoping that everything may be on a server somewhere. This is years of emails, important correspondence, bank information, business, etc. The ONLY thing I can think of is when I download the TB app for android and sync'd it using the QR on the desktop version of thunderbird. I then checked stuff the next day and everything was gone barring emails from that day, all folders, everything was gone. Is there no way to recover this?

I thought I used to be able to access browser history from much longer ago, either way I can no longer see any history longer ago than 29/10/2025 is there anyway for me to restore, download or access older history, or has it been permanently deleted? I do still have a back-up of 28/12/2025 but I don't know if or where that contains history. I'm looking for data between 2019-06-01 and 2024-08-21. Weird thing is I remember accessing search history that old before... though I'm not sure how if if it doesn't store it for that long. Any help would be appreciated.

My computer went through the process of updating Firebox. Afterwards all my bookmarks are gone. I clicked on Manage Bookmarks...then clicked on Import and Backup...then clicked on Restore which open a File dialog box. What file? Nothing is restore. I want the bookmarks restored.

I use Thunderbird to store loacally some email from gmail and delete it from the online server.

Until october last year it was working flawless, to day I need to read an old email and I discovered that locally since october of some email is only stored the subject and somtime I only have the ticker that increase in the stored email email, but there is either not title or subject. I didn't change any setting in my computer or in the antivirus,, the only thing is that I perform the update of thunderbird as usual. Is it possible to recover these emails or they are gone forever?

Best regards

this is still really annoying: https://support.mozilla.org/en-US/questions/1500761

why is the icon even there or why does it have to disappear and then also change the tab size ?

1) if its there to enable you to play a tab in the background, then i want the option to switch the feature on or off (because i do not want to play anything in the background, atleast not via a 24/7 target practice with a mouse)

2) if its there to give you notice that there is a 'multimedia' tab open in your browser, then i want the icon to stay there and not dissapear plus change tab size...

like what is this even ? are we back in the 50s ?

After installing Mozilla on my mobile phone and syncing with my laptop all my bookmarks and history are GONE from my laptop. When attempting to restore them, following your suggested instructions, no dates appear when clicking the restore function. Deleted Mozilla from my mobile phone, still no good. Do I need to recreate all my bookmarks again?! How? When attempting to bookmark a new site it does NOT bookmark! No new history is showing either! Very disappointing, should I just return to windows again after years and years with Mozilla? Andrew S

Everything has been fine for several years but this morning I now get error: TB could not connect to server mail.twc.com, the connection was refused. Spectrum says everything is good on their end. What do I have to do to "fix" Thunderbird? I can't send or receive any emails from 5 accounts with Spectrum and the emails are there when I log in at WebmailSpectrum.net..

When I want to view passwords Firefox is asking windows credentials which I don't have. Now I can't get access. It used to ask for my Firefox password what happened.

06 May 2026 USA Just to inform users:

All mailboxes and all mail in profile are catastrophically and irretrievably deleted when I: 1. Change the location of the profile folder. 2. Make appropriate change in profiles.ini reflecting the location change. 3. Launch Thunderbird in Offline Mode (launching in OFFLINE mode is the fatal event). 4. Mailboxes will appear during this one launched session

    but

5. If Thunderbird is closed while still OFFLINE, then a re-launch of Thunderbird in any state will reveal

     that all mailboxes and all mail have been deleted.

All mailboxes, and of course, all mail in the profile are catastrophically and irretrievably deleted. I was lucky that I made a backup before changing profile location.

The deletion of mail and mailboxes occur at the close of Thunderbird's OFFLINE state. An examination of the profile folder indicates the destruction has occurred upon closing of Thunderbird in OFFLINE state.

It is not the re-launch of Thunderbird that causes the catastrophic deletion. The deletion occurred when Thunderbird was closed in its OFFLINE state.

To successfully change the profile location I must: 1. Make the change to profile location. 2. Make the appropriate change to profiles.ini 3. BE SURE to make the FIRST LAUNCH of Thunderbird in ONLINE mode--ONLINE only. 4. Once 1,2,3 are done, then Thunderbird does not corrupt the profile folder.

Conditions that MIGHT make my configuration uniquely affected: 1. I use Proton Mail Bridge in conjunction with Thunderbird. 2. My Profile folder is on a network share that is letter-mapped in Windows. 3. I have about 10 email addresses in Thunderbird that are Outlook IMAP, Gmail IMAP, and of course, Proton Mail.

I've been using Thunderbird a couple of years in this configuration with no problems. I just decided to rename my profile. So, this is my first discovery of the problem.

First of all, I thank the great volunteers that have structured this great browser- Mozilla Firefox despite the persecutions from the giant Microsoft. I love Mozilla Firefox and I support it. I am of those who wrote petitions against Microsoft for undue negative manipulation of Mozilla Firefox. My petitions went to the European Union, Federal Trade Center, Independent Press Organization etc. The issue of my complaint about Mozilla Firefox is the non-functionality of Mozilla Firefox's Bookmark and History: The bookmark and History has had problem for a long-time. Most people who use Firefox admire the Bookmark and History. Once you open your computer window, on the left of the window, there is a list of your bookmark and you do not struggle to search for your favorite bookmark as in Microsoft Edge or Google It is there on your left. It is the gold standard of structuring a browser. No browser can compete with Mozilla Firefox in this respect. This is the reason Mozilla Firefox remains one of the best browsers ever. If it is Microsoft or any other group, they would have rushed to mend this defect. I know that Mozilla is made up of volunteers. Could any of the engineering volunteers see what I am saying?
