recent firefox update can no longer copy and paste when creating a blog post in Squarespace, I have been using squarespace for around 15 years for my websites and I have never seen this issue, Firefox 15.1 installed and all of a sudden when trying to create a blog post in Squarespace, when I right click a text box pop up and it no longer says paste so I can no longer copy and paste text - this is more than a little annoying, you will not be surprised to know that I am now using Chrome to create my posts, there is no issue in chrome. I am a firefox geek! how can i solve this problem, I just did another update from Firefox, the issue remains I have been using computers for 40 year so I am not a novice but software glitches, I am lost

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?

The recent update changed how the mute button works in Firefox, before it would replace the icon and would show text and whatnot if it was muted or wanted to autoplay; now it just always shows the mute/unmute button in a tab playing audio. This would normally be fine but it is causing my tabs to constantly be shrinking and expanding whenever the audio changes in a tab, and it's really frustrating me and it feels like an overall far worse user interface design than it was before, even if people were complaining about it. Is there some sort of middle ground where I can set a maximum tab size or something? I know this used to be a feature in about:config but it doesn't exist anymore for some reason. I've also tried using a userChrome CSS code for it that I found online; it got rid of the button but it still made the tab size change and the code I tried using for maximum tab size also didn't affect that. Really starting to frustrate me! Please give me any advice I feel like I've exhausted all my options lol

When right-clicking on the Firefox icon in the Windows task bar one can pin entries, which then appear in the "Pinned" section of that menu. The description is taken from the title of the website at that point in time.

I would like to rename one such entry (i.e. change the description). How can I do this? The context menu only contains the options "Open" and "Unpin from this list".

So I guess my Firefox update to ver. 147 from 146 by its auto update feature, but I realized all the past personal data (ie, history, cookies, passwords, profile, etc) was gone.

I have Mozilla Account (I think it's the same as Firefox Account back in the old days), so my personal data is now retrieved from some device as far as possible, but I lost local personal settings like Shortcuts on the main page on my laptop,p which is the main device to do everything.

I can't help what happened to me, and I will rebuild what I used to be on that day, but I am curious if it's just me, or there is some logic to cause this data loss.

Hello,

I am having an issue with my Instagram account on PC (web version).

I can log in successfully, but after logging in the page does not load. It only shows the Instagram logo and stays stuck on the loading screen. Refreshing the page does not help.

Important details:

Instagram works normally on my mobile phone (app)

The account is not blocked or disabled

I changed my password successfully

I tried different browsers (Firefox, Edge, Chrome)

I cleared cache and cookies

I tried private/incognito mode

The problem only happens on PC, not on mobile

Because everything works fine on my phone, I believe this is a problem with the Instagram web version or a browser-related issue on your side.

Please check my account and let me know how I can fix this or regain normal access on PC.

Thank you for your help.

How do I edit my e-mail address to a new one? I have to change all my accounts due to my current e-mail provider retiring their domain and switching to a new one.

When right-clicking on the Firefox icon in the Windows task bar one has the option to "pin" items by hovering over an entry in the "frequent" list and clicking on the little pin needle icon (with the hover text "Pin to this list").

How can I pin items that are not in the frequent list? I have tried for weeks to make an important page a frequent one by making sure to visit it daily but it never makes it to the list.

Hello,

I have a situation - which I had previously researched and resolved - that has come back to haunt me.

I use an ultra-widescreen monitor and searching/browsing obviously necessitates a center-screen search box which, up until now, Firefox has provided cleanly and with simplicity. However, I see that (once again) despite cursor placement in the center-screen box the search text is being entered in the address bar which is wholly impractical for me since I have to look about 60 degrees left and upwards to see what I am typing.

I say "again" because when this happened previously I was able to make a config change and resolve it but despite that still being in effect - the ".handoffToAwesomebar" is still set to FALSE - search text now has moved back to the address bar.

A brief search of this community yielded no answers. Is there any other known fix or has this now be thrust upon us permanently and thou shalt adapt?

Thanks in advance....

Hello. I have two questions about settings. 1. I want to hide the "Take Screenshot" option from the Firefox right-click menu. 2. I want to hide the "Original Profile" option from the options that appear when you click the Firefox hamburger menu.

I'm asking about these two points. 1. I'm trying to hide the "Take Screenshot" option, but I couldn't find a solution even after searching. about:config ↓ extensions.screenshots.disabled ↓ From true to false ↓ Even restarting Firefox didn't hide the "Take Screenshot" option. 2. Regarding hiding the "Original Profile," I can't find any information about this option, so is it impossible to hide it? I'm asking about these two points.

I cannot log in Firefox account. It says I have to log out to log into my account. All I wanted to do is to remove a phone I reset and gave away from my Firefox device logins, but everything quit working with all the AI chaos.

I love my current Firefox settings, bookmarks, folders and color, background image, dark mode. All I want to do is to create a Firefox browser backup file. I don't want to restore or sync anything. I just want a backup file in case of computer failure to restore to my next computer if ever necessary. I'm using Windows 10. I think they used to be "json" files? The only "Backup" link in the menu only addresses Restoring from a file. I just want to create a backup file for this current browser just the way it is. Is there a simple solution? Thank you SO much!!

Mozilla made an update of my Firefox installation on my Win11 laptop. all my password disappeared as well as my history and bookmarks.

I have now a virgin installation and is starting from scratch.

Now I get this error message: "This profile was last used with a newer version of this application. Please create a new profile." I deleted met shortcut and I opened Firefox by using Windows search. Now I see 4 profiles! I think I do not need to create a new profile. Maybe delete 3 of them ? What to do ? And, how?

Hello,

The fonts are not rendering properly on few websites, example(apnetv.xyz), everything was working fine with stable release of v146.

The beta versions were having the same issue, i assumed it was related to Beta releases, so I switched back to stable one. However now firefox has released stable v147, the issue persists. Kindly fix it.

My system was hacked and I had to factory restore it. I didn't write down my login/passwords because I was informed that as long as I had my sign in for FireFox I could restore them on my system.

Alas, I cannot figure out how to do this. I do not have a passkey, a profile or anything other than the email address for my system.

Can you help me? I put all of my important documents in Dropbox and now I can;t access that either.

Anything you can do is appreciated.
