After updating to Firefox 147.0.3 all of my browser history (along with open tabs at the time of updating) is lost. I just updated to Windows 11 workstations (plus a couple of older Windows 10 workstations) to the current (Feb 2026) updates too. However the history data was lost before the Windows updates. I noticed that with the previous update of Firefox that saved login information was also lost. Who is doing your program updates, a chimp?

In the past when an update was done the browser would open back up with all of the previous versions session tabs in tact. But not now.

I've lost several tabs of research that was being done. Based on what has been happening, I will HAVE to change to some other browser. This is a shame as I've been a loyal Firefox user since day one. Good bye Mozilla and Firefox.

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.

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?

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?

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.

I don't know how to get to my prior question to update it I submitted a support question a short time ago about Firefox manage bookmarks using Waterfox version. I now think I could have been duped by the colour of the window bar. I have also found that firefox manage bookmarks does not show individual bookmarks that are not in folders - in the left pane. This also threw me. However, when I click on Bookmarks menu in left pane, the individual bookmarks are all shown in the RHS pane. I have done a quick check and the list does not contain at least two bookmark folders that are in my Waterfox bookmarks - I did not try to check all. I now think there is no problem. Interested whether anyone else has raised this. MY SUGGESTION - in the past I am confident that manage bookmarks function did not use waterfox color. In the next update try to change the manage bookmarks function window to a color different to Waterfox colors. This may not be possible if waterfox simply inherits the manage bookmarks function code incl colors.

Prior question text pasted here for completeness Yesterday I was using both Firefox and Waterfox. Since then when I try to use manage bookmarks in Firefox - I get the waterfox version of manage bookmarks showing the waterfox bookmarks list. Is there a way to get the firefox manage books back again

Hi, I have used "takeout" years before but not one of these.

Can I keep folder integrity using one of these? And how if not obvious.

Quota is high.

Thanks

I seem to be unable to install Firefox on my Windows 11 desktop because there is apparently an old version already on my computer. I wish to reinstall Firefox with your help

My emails were all working (accounts were setup fine). Then, recently, when I opened Thunderbird, the main area (where my messages are displayed) is empty. If I choose another folder, still empty. BUT, the folders all say that there are messages in them (see the attached screenshot)

I have tried the following... 1. Opening Thunderbird in Troublshooting mode: This works, and the messages appear. But I don't want to have to open troubleshooting mode every time. 2. I have ZERO extensions installed, so asking to disable them obviously wont do anything. 3. I have tried to repair the folders (I have tried to repair the default inbox folder, and then tried to repair them all ... nothing worked). 4. I have backed up my thunderbird files, and tried reinstalling Thunderbird. Still didn't work. 5. I tried these three steps ... https://www.mboxtooutlook.org/blog/thunderbird-inbox-missing-emails.html Didn't work either.

Any other suggestions?

I have an existing account on my old computer. When I put Thunderbird on my new computer, it downloaded thousands of old emails but would not open new mail. I uninstalled and reinstalled and it still won't show new mail.

Starting Feb 8, 2026 my yahoo accounts no longer work in Thunderbird. I have accessed these for over a dozen years using Thunderbird. In addition, when I open Thunderbird at all I end up getting endless loops of yahoo login messages. The mechanisms in the messages do not work at all. I have received no Yahoo mail since that date. To troubleshoot the issue I tried logging into the accounts directly through Yahoo. Broken, with no access at all to any help resource from Yahoo. Although Yahoo seems to be keeping mum on the problems, there is spotty information online that Yahoo servers were breached a few days ago. One report claimed that user data for about a billion accounts was compromised. I suppose that may explain why my accounts no longer work anywhere- neither from Yahoo itself nor within Thunderbird. Is there a way to disable the incapacitating yahoo popups pending any larger solution to this?
