Firefox Community Forum

Please provide the exact requirements for defaults in order to have the settings (occurring on the bookmarks settings) to state that Firefox is your default browser. Having had to attempt this process multiple times causes me to question if it is the user that needs some "tender loving care".

I keep getting this error every time I open a new tab.

Secure Connection Failed An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR Error code: PR_END_OF_FILE_ERROR

I have set E:\ as my default download location. However in some cases Firefox does not respect my choice and silently downloads stuff to C:\Users\Name\Downloads. I really hate this. One example, a pdf downloaded from here https://scribd.vpdfs.com/. Please fix it. Thx.

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!

OK, strange thing I cannot understand. an IDENTICLE URL ( cut and pasted from document ) Chrome gives one result and Firefox gives an abbreviated version of the same result. This is most noticable on Ebay when showing 'new today' items where Chrome shows Items that Firefox does not. And , No, its not a refresh or cache issue. Any ideas, thanks.

Firefox recently offered a choice of having open tabs appear in a sidebar on the left side. This is great but the tabs and sidebar stay visible when engaging the f11 full screen mode. This makes an awkward appearance when trying to view in full screen - such as movies or any other. The address bar at the top is hidden with f11, but the side tabs and their vertical side bar remain visible. I believe Firefox would be more desirable if the f11 key also hid the side bar. This is how Microsoft's Edge browser functions. Can't have a true full screen if the sidebar and tabs remain visible. The full screen functions works well if the sidebar function is turned off in settings but this makes it awkward for a user who wishes to use the sidebar tabs with a full screen mode. Thank you for considering this issue and thank you for your great products. Tom

My Firefox browser window has multiple tabs. I would like to be able to close them individually. The tabs do not have the 'x' symbol on them to be able to close them conventionally. I tried to right-click on the individual tabs, but the drop down menu does not have the option available to close the tab either. I tried rebooting the computer but when I open Firefox again, the same tabs are still there rather than opening up a fresh browser window with only the start tab window. I am using Windows 11 with this computer also. Help!!!
