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?

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,
 2. 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?

The last automatic browser update (147.0.3 (aarch64)) has wiped off all changes I made to bookmarks and passwords from the past year.

How can I go back to a previous version and recover my details?

This browser version is terrible and looks exactly like Microsoft Edge which is not intuitive at all. I don't want to set up multiple personas, Its just me and the one computer?

Please help me. Kerri

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.

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.

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,

hi, I love supporting this independent browser - I know its not perfect but it does a great job of doing most things well.

However, and there is a big but. I can be in the middle of an investigation that requires sharing data to a new tab - on opening the tab I'm blocked from going further as Firefox needs to do an update! This is really infuriating. No update can be SO urgent that you stop me using the browser. This is the Microsoft mentality, and its wrong. Can you please investigate NOT forcing users to update their browser during session.

Matt.

The last few days I am unable to load websites that I regularly use. I get a cannot find error message. I have no clue what is going on. I turned off the vpn but that had no effect. This is really hindering my getting things done. Anyone with insight? I cleared the cash and cookies and all that, rebooted the browser as well as the desktop. Thanks

When I try to exit the fire fox browser I delete all cookies then select exit and close it out. However when start my computer the next time I get a message that fire fox is already running and if I hit the cancel button it freezes the screen and I have no options to move on. So how should you do a normal shutdown off the browser?

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

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?

Obwohl in den Einstellung automatische Wiederherstellung alter Tabs eingestellt war, wurde dies nicht durchgeführt. Da ich es zu spät gemerkt hatte, konnte ich nicht über die Chronik die alte Sitzung wiederherstellen. Was kann ich jetzt machen?

Ciao i have lost saved link and short menu links all my 143.0.3. How can i recover or where is saved CSV or else? Thanks Vladi

his is a new issue starting from FF 148.0.3

In FF on my PC I create a folder in the bookmarks toolbar for that day's research. I drag page URLs into there to bookmark sites/pages for follow up reading.

As extpected the shortcuts have the site's icons.

Open FF on my Macbook at home and since this verion, no favionns until I open the respective pages.

This is new. All other sync seems fine.
