Hello!

After the latest Firefox Desktop updates (not sure which one exactly, since I didn't notice the issue immediately), I've started experiencing a problem with copy-pasting text — specifically with line break formatting on Windows 10.

Instead of copying line breaks using the Windows-style carriage return + line feed (\r\n), Firefox now copies only line feeds (\n). As a result, the text appears as a single long line when pasted into native Windows applications — which breaks the expected formatting. This behavior mainly affects:

• Text editable fields (e.g., contenteditable or textarea) in modern web applications.
• Code blocks or snippets (such as in Markdown or monospace) copied using "Copy" buttons (e.g., in ChatGPT or GitHub).

At first, I noticed this only when copying code from ChatGPT using the code-snippet copy button. But now it happens in almost all editable text areas — if I enter text with line breaks manually, and then copy it, those breaks do not appear properly in native Windows apps. For example:

• In Google Sheets, I often edit text with line breaks in a cell, but when I copy it back, it's all flattened into one line.

Right now, I have to fix this using scripts that replace \n with \r\n, but that's a very inconvenient workaround.

❗My main question is: What changed in Firefox that caused this behavior? This used to be reliable and feels like a regression. It’s a very basic feature and critically important for my daily workflow!

🔧 Follow-up questions:

1. Can this be fixed in a future Firefox update? Will it be addressed?
2. Is there a way to fix or configure this behavior right now via browser(settings, configs)?
3. Is there an extension or workaround that can restore the \r\n format without manual scripting?

Affected apps:

• ChatGPT
• Google Spreadsheets
• Trello
• ProtonMail (regular text copying)
• (more)

Thanks in advance for any clarification or suggestions!

Please see enclosed screenshot, it happens when I set a video full screen. It doesn't happen all the time but randomly. The screenshot shows the video before it starts hence the black screen. Refreshing the page gets rid of it but I'd like to know what's causing it in the first place. Using latest Firefox 137.0.2, Windows 10.

While i was trying to search indeed for a job the site started having a glich loading . I'm not sure if that the best term but doesn't fully load. I have had this issue at least 6x in past five years on default firefox setting and if i changed a few to make more secure . When i use other browser that are not firefox based it is fine . It happens on librewolf as well

I get random crashes while streaming video (for example youtube). I am using a laptop with 2 GPUs (integrated AMD and dedicated Nvidia) and a secondary monitor. If the Firefox windows is on the laptop display I never get crashes but on the secondary display I get around 1-2/hour. Also, this only happens with hardware acceleration enabled in Firefox settings, if I deactivate it then the issue is gone. I think it runs on the AMD integrated graphics, based on what I see in task manager. I also have uBlock origin, haven't tried deactivating it yet. The crashses consist in a black screen from which I can only recorver by doing a hard reset.

Any suggestions on what to try?

I have had trouble for months logging in to Ticketmaster and Office Depot Canada. Now, I can't use Firefox to access Crave, which tells me that my "IP address is outside of North America." I am not using a VPN, so I don't know why Crave thinks that.

Help?

Hi there, I'm trying to upload a new version of my browser extension (version 1.4.5), but the submission is being blocked due to a version number conflict. The issue is that I accidentally submitted a different extension under this listing with version 1.7.7. I reverted it immediately, but now I'm unable to upload the correct version (1.4.5) because it's considered a downgrade.

I really don't want to change my extension’s versioning just to get around this, since 1.4.5 is the actual next version in my release cycle. At the same time, I don’t want to stop updating the extension on the Mozilla Add-ons store. Is there a way to resolve this?

There is a special tab area at far left side of tab bar. I once put a site there, but can't recall how to add more. The image included should answer further questions you may have regarding my query.

i can only use the Google Ai Chat Combo for one prompt. following which, the chat combo shuts and become unavailable for writing any further prompts unless i have refreshed the whole page which leads to losing the previous answers to prompts . how to solve this issue?

Why without updating the browser I have a problem where the browser no longer shows the window with the suggested password

Why does your browser break without anyone's intervention, why does it stop showing the password insertion menu as before, and there is no way to fix it. Every time you screw up, I just have to reinstall the browser?
