I am running the latest firefox version 147.0.3 64-bit. Gmail opens and runs fine on duck duck go and brave. Cannot find any info on how to solve/fix/override/whatever on "numeric code 4" but seems like other folks experience, too. I appreciate your help.

When I logged in this morning my FireFox screen had changed. The window for searches had disappeared and the "pocket" selections were all about India and its events. None of the previous options were there. What happened and how do I get back to where things were?

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?

With the old FIREFOX Start/home page I could have up to 4 lines of bookmarks showing on my start up/home page, but now there are only 8 showing. Can I add more, and if so how? Thanks

В России блокируют Firefox, по этому авто обновления не устанавливаются, я бы хотел получить ip и url серверов от куда скачиваются обновления. Это поможет обойти блокировку и восстановить работу firefox в России

Hi there,

I am trying to access this site: https://unabridged.merriam-webster.com/ I am logged in on the site with my membership, which is up to date.

But whenever I try to search a word, it redirects me to the login page. I can only assume that something is wrong with my cookies, privacy settings, and extensions in Firefox. After having cleared my cache, allowed cookies for the site in question, and messed around a bit more with my settings, the problem persists.

This is not happening for any other sites. Can you help? Thank you!

Just wanted to ask about the potential for other Ai providers - Duck.ai being the key one missing.

Is there a possibility of local instances being a feature? Whether it's just hosted locally (not a function or component of Firefox itself) or a Mozilla specific model that's locally run?

Most of the keyboard shortcuts are not working. Copy-paste works, but others for example, Ctrl + F doesn't work. Very confusing and frustrating. Attached is the screenshot of Browser Console and it does show missing attributes. Not sure if this is a browser issue (currently using 147.0.3 (64-bit)) or I need to make certain change settings. I would appreciate any suggestions to resolve this issue.

I’m currently experiencing an issue when trying to use Membership Anywhere through the Firefox browser. Membership Anywhere is a digital membership management platform that many organizations use to manage memberships, events, and member interactions efficiently. While the site works fine on other browsers, certain features, like logging in, accessing the member dashboard, or completing payments, do not function correctly in Firefox.

Specifically, I notice that some pages fail to load completely, and certain interactive elements, such as buttons or form submissions, don’t respond. I have tried clearing the cache, disabling extensions, and updating Firefox to the latest version, but the issue persists. This problem is affecting not just my access but could impact other users of Firefox who rely on Membership Anywhere for managing their memberships digitally.

I wanted to check if there is any known compatibility issue between Firefox and Membership Anywhere, or if there are specific settings or security features in Firefox that could interfere with this platform. I would greatly appreciate guidance on how to resolve this issue so that I can continue using Membership Anywhere smoothly without switching to another browser.

Have tried different solutions like Malware product and cleaning cashe and cookies. When I search a known safe site I get redirect by Convertitmas stating the (known safe) site is unsafe. Best regards Henrik Nygaard
