We want to use Firefox on a locked down system. Using the -kiosk command line argument gets us most of the way there. But they still have access to the devtools when they hit F12. It appears there are ways to disable devtools after the browser has been started. How can we disable the devtools before the browser is opened and without registry changes?

Dear Firefox Team,

I hope this message finds you well. I would like to suggest a small but useful enhancement to the Firefox interface that I believe would improve user experience and accessibility.

Currently, in the "Customize Sidebar" section, the available tools are limited to a few items such as AI Chat, Tabs from Other Devices, History, and Bookmarks. I believe it would be very helpful to include "Downloads" as an additional sidebar tool.

This would allow users to quickly access their recent downloads without needing to go through the menu or use shortcuts. It adds convenience and aligns well with the purpose of the sidebar — offering quick access to frequently used features.

Thank you for your time and for continuously improving Firefox. I look forward to seeing future updates! Warm regards, Julabeeb a firefox user, developer, and contributor

Yesterday evening I accidentally clicked on a setting that asked me to stop or deny something and I don't remember what it was. Today my bookmarks and history prior to yesterday evening is gone. Is there a way in the system to go back to yesterday evening and undo whatever I clicked and restore the missing history and bookmarks? I work on MacOS and am using the current version of Firefox 137.0.2 (64-bit)

No sound when showing videos, i.g youtube etc, in firefox. Works fine in Chrome, and yes, the volume is on in firefox and laptop (Win11).

Is there a setting I have inadvertently touched.....?

Thanks!

I have to manually change the layout.css.devPixelsPerPx setting evertime I switch from my laptop to an external monitor. What can I do to avoid this every single time?

bold text I recently reinstalled Firefox on my Android tablet to fix an unrelated problem. I can now find no way to set a web page as my home page. Can I still do so? Why is it so hard to find if I can?

I'm afraid I cannot continue using Firefox, after the last change, since I can no longer keep my tabs open after closing a session, as I specified in the settings: "Open previous windows and tabs." Can someone help?

Find on Page suddenly stopped working. Neither CTRL + F nor clicking the command on the toolbar do anything. It happens in Troubleshooting mode as well. Restarting Firefox and the computer, refreshing data etc. didn't help.

I use Firefox as my go-to browser on my Windows 11 PC with the google search engine as my homepage. However, every time I open Firefox, a google sign in window pops up. How do I disable this? I only find instructions on how to do it with Chrome or other browsers, or where step-by-step instructions skip steps.

Please help!

Hello, I can’t scroll anymore when enabling the performance settings ([https://support.mozilla.org/en-US/kb/.../performance-settings] ).

Is this a known bug? Is there any fix?

Thanks!

Hello,

I deleted my menu bar. The menu bar was on the very top of my screen and the first column was Filer. How do I get it back?

Thank you, Victor Orr
