I was using TB like normally on windows 11 when it crashed. Now every time i try to open the app it prompts me to send in a crash report, but every time i press "restart thunderbird" a new window with crash report shows up. I have tried writing a comment, checking and unchecking all the boxes and pressing quit thunderbird. But i still get sent into the loop.

So when I did a search in Firefox Android via Google I noticed that the search results were in chinese. I checked on my other browsers (Opera and Chrome) and their search results are still in English. Yes, I am using WARP by 1.1.1.1 but if that's the cause then the other broswers should have been in chinese too. I tried doing clear cache then clear storage but it was still in chinese when I did my first search in that resetted Firefox. Might be relevant information: I had uBlock Origin installed when I first experienced it and after I did the clear cache and storage thing.

Hello, and thanks for the read...

ISSUE: Every day I have to call the telecom ROGERS that took over for telecom SHAW, turn IMAP and Pop3 on 9 Email accounts (they lost 1). Sometimes the 1 to 2 hors chat w/ a human turned it back on will not last long.

DETAILS:

1. I can receive outside Emails *because I can't send using Shaw/Rogers, checking for Email, just hangs at trying to login in to any of the 9/10 emails.
2. When I can get a support person to check, they tell me that IMAP and POP3 are turned off.
3. They will tell me they re-enabled it. But it doesn't enable for me.
4. It all works OK when using the online webmail Zimbra. However, I need to check 3 of the 9 email accounts every hour, others every 6 hours, and others once a day at boot.

QUESTION: When using POP3, does the setting on my SMTP need a special setting on Thunderbird?.

NOTE: I am complying with "Rogers With Shaw" passing the buck to the Email Client (Thunderbird) by asking here - "Could It Be The Email Client'! And my answer is 'No', because Thunderbird works perfectly with 54 other Email accounts.

Thank for reading this, and for any input you may add, ~r

All of my history except of today's has disappeared. I did not erase my history, and really need it back. I did try to remove a couple of sites from my Most Visited, as Firefox was saving all sorts of sites I don't really visit often. In addition, I am being asked to sign in with my password at every site I go to where as before I was automatically allowed to enter, as all my passwords are saved. What happened - and how can I get back to normal?

Contributor note: bookmarks are also missing (/questions/1578816).

- Thunderbird set up 19/05 & email/ history /folders downloaded - Moved from DNS to GANDI Email server provider this week but now all folders/historic email are no longer visible in Thunderbird email - How do I get them back and how do I synchronise Thunderbird & Gandi so that emails shown in WEBMAIL include all History and not just new emails since Gandi switched on? Thank you.

Firefox version 152.0 : Firefox is continuously refreshing the page on a particular Website, in both Windows11 and Linux versions, making the site unusable ( unable to click anything ). The website loaded ok previously using Firefox and still loads ok using Chrome. Disabling extensions doesn't help, neither does deleting the cache and cookies. What changed and why? Is there anything else to try?

How do I stop this page from coming up several times a day. I have already set FireFox as my default browser, several times, but to no avail. I've careful followed your instructions. I dislike MS and have used FF for years. If this doesn't stop, I'll search for another browser that hopefully behave. I have set it on 4 computers, 2 Win 10, 2 Win 11.

By the way, the computers show FireFox twice, but only one actual installation.

Please do better!

Ask AI isn't optimized for firefox. Query box text isn't cleared after text submission. Also occasionally scrolls to the bottom where I have to scroll back up to read it's response.

Logging in to Twitter/X is no longer possible as of a couple of days ago. After entering the username, pressing the "Next" button does nothing. Using the Desktop or Mobile version of the site makes no difference.

I had logged this issue in early 2025 but it has never been resolved and still exists.

I received a reply today, Tuesday 7th July, from Wayne Mery, who said "If you are still having problems when using a newer version, please post a new question and we'll take a new look at it.". as the original post has been archived.

So, here are the details:

"I am currently running Thunderbird 152.0.1 (64-bit) and I don't get an automatic prompt for updates and haven't been getting them since I updated to Supernova and now Nebula.

I have the settings set to Check for updates, but let me choose whether to install them, which is the setting I have always had and I used to get automatic prompts for updates with a window opening to show the details of the update as I get in Firefox.

Can someone tell me how to get these automatic updates back."

I have attached a screenshot of the original version.

Thanks.

Hi

I have set up Thunderbird with a Zimbra mail serveur (Zimbra serveur 10.1.10_GA_4785) using the EWS new feature of Thunderbird.

I can setup the EWS account. The test of the secured connection to the server is returned valid. But in the mailbox, the list of folder is empty, and I see no email. Interestingly, I can successfully send email from this thunderbird using the exchange server as sending server.

To resume, no emails are received, but sending emails works.

So, I check the request to the exchange server when starting a synchronization : Here the result : Request : <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"><soap:Header><t:RequestServerVersion Version="Exchange2010_SP2"/></soap:Header><soap:Body><GetFolder xmlns="http://schemas.microsoft.com/exchange/services/2006/messages"><FolderShape><t:BaseShape>IdOnly</t:BaseShape></FolderShape><FolderIds><t:DistinguishedFolderId Id="msgfolderroot"/><t:DistinguishedFolderId Id="inbox"/><t:DistinguishedFolderId Id="deleteditems"/><t:DistinguishedFolderId Id="drafts"/><t:DistinguishedFolderId Id="outbox"/><t:DistinguishedFolderId Id="sentitems"/><t:DistinguishedFolderId Id="junkemail"/><t:DistinguishedFolderId Id="archive"/></FolderIds></GetFolder></soap:Body></soap:Envelope>

Anyone successfully used the new EWS feature with Zimbra server ?

PS : I confirm the EWS connection with the Zimbra serveur by successfully using EWS on Outlook for android.

The VPN was working a couple of days ago, but now if I switch it on, the browser is unable to use any website. The country is displayed in the bottom left corner as "Australia" even though I set the VPN to Canada.

Hello dear forum Here are the details: Account type: Microsoft Exchange (via OWL) Antivirus software and firewall used: Bitdefender I have the following problem: I copied the mbox files from the active account (profile) to Local Folders (as described in some forums), both with and without *.msf files (seems this makes no difference to the problem). Then I start Thunderbird, and all folders and subfolders appear in Local Folders. However, when I go into one of these copied folders or subfolders, it only displays a single email. The copied folder is the same size as the original, but no other emails are displayed, and this is repeated in every subfolder. I employed the repair function with no result. The import/export tool NG only copies half of the emails. The total is 4.25 GB. I can only copy the emails manually via copy/paste, but this is very error-prone and takes a very long time. Has anyone had experience copying mbox files and managed to do it successfully? I would be very grateful for any advice.

Good afternoon,

We are experiencing the following issue.

I work as a Technical Support Engineer at a large company in Russia. All of our branches use Thunderbird as their email client.

Approximately three weeks ago, we started receiving reports from users that their email was no longer working.

After investigating the issue and trying to identify the root cause, we have not been able to find a permanent solution. We have already tried the following:

1. Completely clearing the cache, rebuilding the mailbox while preserving emails, and allowing Thunderbird to re-download all messages. 2. Changing the `mail.server.default.mime_parts_on_demand` and `mail.imap.mime_parts_on_demand` configuration settings to `false`, clearing the Trash folder, and restarting Thunderbird. (This only provided a temporary fix.) 3. Reinstalling Thunderbird and creating a fresh client installation. 4. Using the **Repair Folder** and **Compact Folder** options for every mailbox folder. 5. Several other troubleshooting methods found online, none of which resolved the issue.

According to multiple users from different departments who are not connected to one another, they all describe the same behavior:

Thunderbird stops working for about half a day. Then it starts working normally for approximately 15–30 minutes, after which it stops working again for another several hours. During these periods, no new emails are downloaded, regardless of the size or content of the messages.

When checking the mailbox size in Exchange, it reports:

• 3.56 GB used. The quota is unlimited.

However, on the local computer, the Thunderbird profile folder (`Thunderbird > Profiles`) occupies nearly 9 GB. If we calculate the size of all mailbox folders within Thunderbird itself, the total is approximately 6 GB.

Does anyone have any suggestions on what else we can try?

Has anyone experienced a similar issue or found a solution?

At this point, our employees are unable to work effectively because email is a critical part of their daily workflow, and we have been unable to identify a permanent fix.

I'm running Thunderbird v.115.10.1 on a Mac. All of a sudden, I am getting the following error message when I open up TB or check email: "Sending of password for user did not succeed. Mail server pop.earthlink.net responded: Internal error”. If I exit TB and log back in, I usually don't get the error message again and TB downloads incoming emails. I have no problem sending emails. It is still usable, but annoying because it happens 75% of the time. Any help is greatly appreciated. Thank you. -Dave

Certains de mes identifiants sont inopérants lors de l'utilisation de Firefox en mode navigation privée ; cependant, certains sont actifs en navigation non privée. Les mots de passe sont bien stockés, mais ni les valeurs automatiques ni celles saisies manuellement ne fonctionnent. Les identifiants qui ne fonctionnent pas en mode privé, fonctionnent dans Google Chrome. Pourriez-vous m'expliquer comment résoudre ce problème, en français ? Merci.

I have been told to disable my ad-blocker by some commercial web sites and I understand that. But I am also not seeing charts and other non-ad items on web sites such as this one: https://www.medscape.com/viewarticle/alcohols-health-myth-over-how-tell-patients-2026a1000map?ecd=wnl_tp10_daily_260703_MSCPEDIT_etid8475291&uac=146695DK&impID=8475291. I don't want to change my default browser but this is a recent development that seems to be impairing my viewing of pertinent items placed on legitimate web sites. Could you please tell me how to adjust my browser settings to stop this from happening? Thank you! Best regards, Bill Strike

Hi, I had to reinstall my windows where I thought my Firefox would sync up upon reinstallation. However, nothing would sync up and the best I could do myself was to import pretty out-of-date Chrome data. When I to my firefox account and scroll to connected services I see my last PC name with its firefox login. Is there any way to recover that data and import to my current device? I read you kept sync data as encrypted data on your Mozilla servers, so I hope that's a viable solution.

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!
