Firefox Community Forum

When trying to set Firefox to open a file on Windows 11, it is overwritten by Firefox Nightly. I have both branches installed.

This is how it goes when attempting to set Firefox as a default application in my machine:

1. "Apps > Default Apps"
2. .mp4 (for example)
3. click the button below that displays the current default application
4. Firefox Nightly appears in this menu
5. "Choose an app on your PC"
6. "C:\Program Files\Mozilla Firefox" ... "firefox.exe" ... "Open"
7. Firefox Nightly remains in this menu

I cannot get Firefox to appear as an available app in this menu. The only workaround, although inconvenient, is to drag and drop files straight into Firefox.

Any help would be much appreciated. Thanks.

After a recent change the browser scroll always goes to the bottom of the page. Before it was always at the top of the page. I found no way in Firefox to reset this function.

I have reset Firefox as default browser on my Windows 11 PC a hundred times in the past few months. Today, I could not reset it at all -- I click the default button in Windows 11 and as soon as I close that settings window, it disconnects. I've run out of things to try to fix this. I think it MIGHT be related to Norton 360, because I first notice this problem when I opened Norton.

There seems to be no possible way to change the shortcut for peeking at the tabs in the sidebar (when sidebar revamp is enabled) from the about:keyboard UI. I have so far managed to modify the shortcut through intercepting function calls.

What I have done: 1. Read through the JS source code for about:keyboard which says the shortcut ID is `toggleSidebarKb` 2. Added hooks to intercept `RPMSendQuery` calls 3. Modified the shortcut through devtools open on the about:keyboard page with the following snippet

```js await RPMSendQuery("CustomKeys:ChangeKey", {

 "modifiers": "accel",
 "isValid": true,
 "key": "S",
 "shortcut": "Ctrl+S",
 "id": "toggleSidebarKb"

}) ```

The way I am doing it is definitely a hack. I am not sure if I am missing something. Although the shortcuts for bookmarks, history, and GenAI chat sidebar are present, there seems to be no entry to change the sidebar toggle shortcut itself. I'd love to work on this but I haven't been able to mach bootstrap on NixOS.

Thank you for any assistance :)
