I have been dealing with this issue for the last several thunderbird versions. I am currently running 115.18.0

Everytime I try to configure an existing gmail account for thunderbird via File -> New -> Existing email account

I specify my Name and gmail email address, then password for the gmail account.

The google authentication pop up launches " Mozilla Thunderbird wants to access you Gmail" and I click "Allow"

As soon as I click "Allow" I am asked to download a file.

Google gemini says this file is a sign that Oauth is not being accepted by thunderbird.

What I have tried. I verified Thunderbird is set to accept cookies I have verified there are no previously stored gmail passwords (as this has never worked) I have changed my default browser from Firefox to Brave and verified the same behavior

please help, Thunderbird has never been able to connect to gmail when running on this Ubtuntu install.

I have updated my firefox on W11 laptop to the latest version 147.0.3 (64-bit) but it cannot show any pictures from some, but not all, sites. Not from www.svt.se nor from www.yr.no But its ok from other sites, as www.tradera.com and www.kjell.com

It works fine using android firefox version 147.0.3

Any ideas, anyone?

Is there something changeable in Firefox that would allow things to display better? On Tue, Feb 3, 2026 at 11:27 AM Douglas Flegal <toemeister@hotmail.com> wrote:

Answer: Thanks for flagging this. We’re aware that some parts of the newsletter may not display correctly in Firefox, while they do load in other browsers. Unfortunately, this is a browser-specific issue and not something we’re able to control on our end.

Sometimes I want to enter arbitrary IPA strings into websites from my phone. I've tried finding a privacy-respecting way to conveniently do this and the best way I've found so far is to use the app Unicode Keyboard by Tim Wunderlich, available on the Google Play Store, and enter the code point for the IPA letters or diacritics I want. This works in every other app, but in Firefox, there are two characters I can't enter this way - the combining grave diacritic U+0300 and the combining acute diacritic U+0301. Even other combining diacritica work. I like researching and talking about linguistics and conlanging online, and sometimes this involves using those diacritics to mark tones. This is such an odd specific incapability for Firefox to have but it has persisted, since at least as far back as 2024. I've just had to enter those diacritics in another app and copy&paste them in. I can enter the diacritics directly as keyboard input in Firefox on Windows and GNU/Linux.

[article] This article claims there is an "AI Controls" section in Settings. This is not found in v 147.03 (up to date) for Mac. Please let me know how to disable all AI in Firefox.

good morning,

I am having problems using a third-party website, playing chess, and one of the functions on their website is not available to me because I keep getting an error message. they have a forum on which I am discussing this issue with one of their Mod's, and he seems to be under the impression it has something to do with my Browser (Firefox 115.32.0esr) storing site data, and that the file in which this is stored has become corrupted in some way. I have no idea how he arrived at this conclusion but that is what he said.

I assured him that, "in Firefox, under <Privacy and Security>, in <Cookies and Site Data>, there is an option marked: "Delete cookies and site data when Firefox is closed." this has a tick box next to it and on my computer this has been selected for about the last five or six years. the browser does not retain site data or cookies and deletes them each time it closes. when I follow the instructions you linked to, and click <Manage Data>, there is no data to manage. it does not exist."

however, he replied to this that: "I don’t think that setting deletes Local Storage, though I’m not 100% certain."

one observation I make is that when I open the <Cookies and Site Data> <Manage Data> dialogue, the websites I have visited in the current session are listed. this data therefore does exist, and there must therefore be a file, even if only temporarily, containing this data. my question is about what exactly happens to this file when I close the session.

1) is the file emptied of data, but still exists as a file.

or

2) is the file physically deleted so that it no longer exists.

if, after the session, I reopen the browser and select the <Clear Data> dialogue and click <Clear> does this simply empty the file or does it physically delete the file. if the file still exists, is there any way to ensure that it is physically deleted in order to confirm that it is not corrupted in some way?

thank you.

When I log in to my Apple tv account on the Firefox browser, it comes up, but won't play the selected program. All other streaming services I subscribe to work fine on Firefox, as did Apple tv until this week. If I try running Apple tv on Google chrome on the same lap top, it works fine too. Ditto on my iPhone using Safari. I'd prefer staying on Firefox to stream Apple tv, but can't make it work at the present time. Can you help?

Summary: Uploading a file to a custom webapp with Chromium (Edge) works but consistently fails in Firefox. In Firefox the request is created, and times out. The server receives no file and logs “missing file.” The same webapp code is running on both Chromium and Firefox.

Environment:

• Next.js app (pages/api route)
• Endpoint: POST /api/file-upload
• Client: fetch(url, { method: "POST", body: FormData, credentials: "include" })
• Server: export const config = { api: { bodyParser: false } } + multipart parsing (formidable)
• Edge/Chromium: Version 141.0.3537.85
• Firefox Version 147.0.3 (64-bit)
• OS: Ubuntu 22 / Linux

Steps to reproduce:

1. Create a FormData object and append a local file:

  const fd = new FormData();
  fd.append("template", file, file.name);
  fetch(`/api/file-upload`, {
    method: "POST",
    body: fd,

1. In Edge/Chrome, upload succeeds. Server receives multipart body and parses the file. Actual behavior in Firefox:

• Transferred: 0 B
• No response status/body
• Client times out (Upload times out)
• File upload request received
• No bytes read server‑side.

Evidence:

• Edge request logs:
  • content-type: multipart/form-data; boundary=----WebKitFormBoundary...
  • bytesRead ~1.69MB
• Firefox request logs:
  • Transferred 0 B
  • File upload missing file field

Notes:

• Client FormData is valid; we log file.name and file.size right before fetch.
• There is a CSP report‑only warning (frame‑ancestors) when using a fallback iframe approach, but we are not using iframe in the failing case.

Question: Is there a known issue where Firefox blocks or fails to send and multipart/body can be stripped before it leaves the browser? Is there a recommended workaround that does not rely on browser sniffing?

Not sure if I need to reinstall. I have an account. I'm looking for the page with the checkmarks (hide people you know, wants to be friends, delete entire right side, etc. There have been an overwhelming abundance of ads sneaking into my feed. Should I re-install? Actually, I tried but nothing gets updated. Mostly, I have relied on F.B Purity probably 10+ years. And now I don't know how to revive it.

После включения ПК бывает, что я не могу ввести текст в браузере.(как буд-то включается режим только для чтения, что не позволяет текст ввести). горячие клавиши работают, но текст не вводиться только в браузере. Оно само по себе проходит. Как это исправить?

I have an idea for improvement of the mozilla browser, but I don't want to send it online here. So can you please give an email address and I will send it there instead(?).

Hi, Since the search open tabs function is part of the overflow button in a horizontal tab layout, when you switch to vertical tabs, you lose that search function. Is there a way to add it to my vertical tab layout? Thanks, Scott

Hi,

I just updated to the latest version of Mozilla FireFox and my bookmarks dissappeard.

All are gone, I wonder how I can get them back?

Many thanks,

Hello. I have followed the instructions to copy the profile file to a drive and take it to the new computer so my Thunderbird will be the same on both laptops.

BUT I get a message that the profile file is not available. And I searched for the file by name and found nothing!

The actual message is attached.

I need to copy my emails to the new laptop.

In the past week emails from one of my friends started going into junk mail. The person in in my contacts. I selected 'enable adaptive emailjunk mail..." and selected the correct address book. The mail still went to the junk folder. I changed the 'move new junk mail to: my inbox, still went into the junk folder. I had him send me 10 emails that I marked as 'not junk' still no success. My emails come from yahoo.com - went there and there was nothing in the spam or junk folder in my yahoo email account. This is happening to only one email address. There's nothing strange in the title of the email or the content. I've run out of ideas.

This is a new Fedora-42 desktop, upgraded (dnf upgrade) today. I installed Thunderbird today (dnf install thunderbird), after doing the operating system upgrade. I tried to add my yahoo e-mail account. Settings are as follows:

• create accounts in the new Account Hub is unchecked (off).
• accept cookies from sites is checked (on).
• remember password is checked (on).
• I'm using "IMAP".

When I click "Done", a separate window pops up in which yahoo asks for my password. After entering it, yahoo says "Something went wrong", and gives no other indication of what the problem is.

If I instead "Configure manually"... I tried both the default hostnames and "export.imap.mail.yahoo.com" for the outgoing server. I tried both "Normal Password" and "OAuth2" authentication methods.

In all the above cases, I get "Unable to log in at server. Probably wrong configuration , username or password." with a yellow background.

I see nothing of "Edge Too many requests" as was happening to several people recently.

How do I add my yahoo account to this new Thunderbird on Fedora-42?
