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

When using Firefox mobile for android, a black bar appears at the bottom of the screen, above the address bar. Please see attached picture.

It only seems to occur when the "scroll to hide toolbar" setting is disabled. The bar moves upwards when using the keyboard.

Samsung galaxy s25 Android version 15 Firefox version 147.0.3 (Build #2016141759)

Please let me know if any more information is necessary.

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?

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

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

I have Norton 360. I just reinstalled a brother printer and now I get the "Your browser is being managed by your organization". While I sync with my laptop, as others have said, I'm not an organization. There is an Enterprise policy .

Active Policy Name Policy Value ExtensionSettings {"firefoxhpsureclicksecurebrowsing@bromium.com":{"installation_mode":"blocked"},"firefoxhpwolfsecurityextension@bromium.com":{"install_url":"https://addons.bromium-online.com/wsx.xpi","installation_mode":"normal_installed"}}

I can't store or edit any bookmarks. How do I correct this? I need answers in very simple terms as I am very much a layman with computers. Thank You!

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,

There seems to be a glitch that I keep encountering when trying to sign in through my TV provider, particularly Verizon, to watch DisneyNOW or TCM or any other service for that matter. The website known as "ssoauth.verizon.com" seems to keep hanging on the message "Please wait - we are verifying your account," and the sign in never gets completed. I already tried clearing my cache and history but with no result.

Even trying to submit troubleshooting information is causing the form to crash here. If you would like, I can send you a text file containing the log I saved from the browser console.

Hello, I use a shortcut link in my book marks bar to access my apple email account throughout the day on my mac. Apparently my firefox browser was set to auto-update and the new update today has presented some problems. None of my icloud apps are loading either using the updated browser.
