How to change home page and new tab to desired URL or any extension of Firefox desktop in 2025?

I am unable to find any way to change how my new tab should look when I click + sign or new tab is opened up on browser opening or re-opening unlike Chrome.

I hate the change of position of typing from the search bar on the current new tab to the URL bar (unseen or unheard in Chrome) that Firefox implemented without considering users who would detest it.

Using Firefox 131.0.3 (64-bit)

Why it disappeared? It was always there. I am logged in Pocket and tried to restart Firefox. Maybe it has to something do with recently added AI side panel? It seems that since then my Pocket icon is missing. Browser version: 140.0.2 (64-bit) OS: Linux Mint MATE 21.3 (Virginia) Kernel: 5.15.0-143-generic

There are 4 toolbars at the top of the Firefox screen. The default order from top to bottom seems to be:

 Menu bar
 Tabs bar
 Navigation bar
 Bookmarks bar   (which Firefox apparently calls "PersonalToolbar")

I would like to move the Bookmarks bar above the Tabs bar so the order is;

 Menu bar
 Bookmarks bar
 Tabs bar
 Navigation bar

I tried to use ChatGPT to accomplish this. After well over 6 iterations, I gave up (ChatGPT was still going strong - hallucinating?). The only code in userChrome.css that accomplished this is shown below. Unfortunately it leaves the order as:

 Bookmarks
 Navigation
 Menu
 Tabs

Can a human expert help me where ChatGPT failed? ___________________

Does anyone know where Mozilla wallpapers are stored? I wanted to set a wallpaper from Mozilla's menu as the desktop wallpaper on my laptop. I looked for hidden files and checked the forums, but I can't find them in the given locations e.g. my profile. Maybe these files are masked somehow. I'm looking for particular wallpaper from the abstraction category (screenshot). Can anyone tell me how to find it?

If I select "Privacy & Security > History > Clear history when Firefox closes > Settings > Data > Site settings" what SQLite files affected when Firefox closes?

I suspect in the profile folder directly, there's a file called "storage.sqlite", but there seems to be more things affected because the whitelist for my cookies is also wiped-out.

In my experience (115.23.0.esr), when I request to remove site data when Firefox closes, it wipes out my cookie white list, so I want to manage that myself.

I have really liked using the "refresh" button with my Firefox browser. The "refresh" button has disappeared from one of my two Dell PC's (I use Windows Eleven, and my Dell PC's have solid state drive). I know there are two other "help" buttons ("troubleshoot mode" and "clear startup cache"). The "refresh" button has really helped me to keep my Firefox browser working properly with my two Dell PC's. Thank you for any comments you might have about this.

On startup why doesn't my Firefox homepage open in full screen mode any more? When I tap the Firefox Icon to begin a Firefox session, Firefox opens in a small window in the upper left corner of the screen. I can minimize that small screen. Then tapping when the Icon once again, Firefox opens full screen. I am unable to get a screen shot to show this small window.

Hi! Why I lost the customize button on my Firefox's home page? This happened after the last Firefox upgrade.

Your help will be greatly appreciated.

FF ver 140. just loaded and now all my sidebar bookmark fonts are black on black. How do I change the sidebar bookmark font back to white? When I disabled all Themes the white color came back, but enabling any theme and they the font turns black again.

A few days ago I changed to a new computer.

On my old Windows 11 computer in Firefox I could sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, edit my posts, post new posts and see the sign out option.

But on my new Windows 11 computer in Firefox I can sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, but I can't edit my posts. I am signed in but Firefox doesn't show the sign out option.

Whereas on my new computer in Chrome I can sign in with my [edited] @gmail account to my Blogger blog, see the New Posts page, edit my posts, post new posts, and see the sign out option. As always.

In Firefox it says there is something wrong with my [edited] @gmail account and to refresh it or change to another account. I don't now how to refresh it and changing to another Gmail won't work. But it lets me in to my blog's New Posts page!

How can I in Firefox on my new computer edit my posts and see the sign out option, as before and as always in Chrome?

When accessing about:logins, Firefox prompts for system authentication (Primary password or master password). However, if the user cancels the prompt twice, the password manager still opens and displays all saved logins without authentication.

This behavior bypasses the intended security check and could pose a risk, especially in shared or public machines

Firefox 139.0.1 (64-bit) on Windows 11

I occasionally increase the zoom level of websites (usually forums) with Ctrl+mouse wheel if the default text size is too small. However, if I forget to set them back to 100% (Ctrl+0) before closing the tab, the next time I open that URL, it's at the former adjusted zoom level -- not 100%. Really annoying.

How do I force Firefox to open all URLs at 100% regardless of the last custom zoom level? I have default zoom already set to 100% in Settings and Zoom Text Only is not enabled.

Thanks.

My bookmarks from an older Firefox version are in JSONLZ4 format and when I convert them to html for import to a current Firefox version it loses bookmarks. Firefox will not allow me to import the original JSONLZ4 file. How do I import my bookmarks?

I tried to remap the Tools > Page Info shortcut from Cmd + I to Ctrl + Opt + Cmd + I in macOS keyboard settings, however, despite the keyboard shortcut listed beside Page Info appearing to change, "Cmd + I" still brings up Page Info.

I read on another [https://support.mozilla.org/en-US/que.../1287036] post that the Shortkeys extension might help but the developer info page states that default keyboard shortcuts cannot be modified with the extension.

Creating an autoconfig file was also suggested [https://support.mozilla.org/bm/questi.../1381773 elsewhere, but I don't seem to have a defaults/pref directory in Contents/Resources inside Firefox.app. A guide on what to put in these files to change the default keyboard shortcut for Page Info would also be appreciated.
