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?

I've been searching for three days now for a solution that will work to restore my profile from a crashed windows-7 machine to my new windows-11. Nothing listed in any forum or help desk works as described. I used to be able to just rename the folder to the exact file name on the new PC, but windows 11 won't let me do anything. It always needs admin permissions and even after I activated the admin account and assigned a password, I still cannot copy to the folder or rename the folder. Every attempt to do this on W-11 fails. It shouldn't be that hard and I'm tired of wasting days playing with this. I have important bookmarks, passwords etc. I want restored, and I need help. Nobody wants to pick up a phone anymore to assist!

I have never used "sync" because I have multiple PCs and each used for different applications and yes some go back to W-7, the operating system that actually worked well. Each PC has Firefox and a distinct bookmark file.

I went to "about:profiles" and created a new profile thinking I could copy to the new folder, but when i switched profiles I couldn't get back to the original default! HELP!

I have a two monitor setup. Since I installed the new AMD driver (26.1.1), sometimes when I play a game on my main monitor, and watch stream on Twitch in Firefox on my second monitor, it can cause the PC to freeze completely. I hear the sound, but the image is stuck.

I tried to disable the hardware acceleration in Firefox, and it seemed like a good solution. But because of that (which is its function), sites became laggy.

Is this a Firefox, or an AMD issue? Or Windows (I'm on Windows 11 25H2)? I will try to install an older AMD driver, but honestly streams had became laggy before the driver update for me.

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.

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.

Hello,

Since yesterday every time i reopen my Firefox it is not loading my tabs that I had opened in previous use "Open previous windows and tabs" setting is enabled/marked and I have not made any changes in settings myself for this issue to take place. I am not sure why did this start happening out to the blue. But I have noticed when I use exit button via 3 bar drop down menu and then reopen Firefox my open tabs are there but when I use the "X" (top right corner) and re launch Firefox my tabs are gone. Is this the new "feature" or am I missing something

Regards

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.

Is there a way to completely opt out of having AI in my browser?

I find recent implementations of AI in Firefox quite frankly disgusting. I don't want to see it, I don't want to use it, I don't want it suggested to me. Not only it's unneeded, but also all your LLMs are a waste of electricity, fresh water and are a threat to my privacy, and we don't even mention all the legal trouble AI scraping creates.

I need a switch to completely remove any mention of LLMs/AIs in my Firefox browser unless I search for it on the internet (and, trust me, I wont; I'd prefer to continue thinking for myself and having real people with skills and talents do things if I can't do them myself) and have none of them touch me in any way. Kill that thing with fire.

Ideally Firefox, one that advertises itself as a secure browser with respect towards its users, shouldn't have any mention of AI in the first place, you know. But since companies are in a craze about it for some unknown reason (trust me, we don't want it; if I want to be lied to, I'd go to a paediatrician to talk about my symptoms, not a language model I can't trust with my data), at least give your users an option to get that awful thing out of their browser it they want to.

Have a nice day. <3

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?
