Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

The release notes for Firefox version 140.0.1 indicate the extension button can can now be removed from the toolbar.the noes say:

"Firefox Extensions: Customize your toolbar with the option to remove the extensions shortcut, giving you more control over your browser. When the button is hidden, you can access the extensions panel again at any time from the Firefox menu by clicking the Extensions menu item."

I still cannot drag the button down and out of sight by customising the toolbar.

Suggestions welcome.

Please how do I stop these floating windows above the tabs in Firefox 131.0? They mostly cover up the tabs and make it difficult to impossible to open or close tabs. The floating window only half shows up above he tab. This is just insane and makes using Firefox almost to much to deal with. Every time I get near a tab the floating window appears and tells me what the tab already tells me. Come on this is GARBAGE!

H E L P !!!! PLEASE....

I searched how to disable any random new AI features Firefox was about to cram into the browser.

I was served this support page that says I can "Block new and current AI features (single switch)"

Simply, the described feature to disable AI features isn't in the settings. I've look and tried searching for "Block AI enhancements" & "AI controls" but no luck.

Please tell me they haven't given the writing of support pages to some shitty LLM.

In other browsers when I add extensions, I can open an extension panel, or got the the browsers installed extensions section, and edit open up my extension setting pages, and edit them. For example uBlock Origin, but there are others. It doesn't seem possible to do such a thing with Firefox. Is that on purpose or is something wrong?

I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

I wanted to use the new VPN feature and the icon initially showed up in the top right, but it has disappeared and is not present in "customise toolbar" or privacy settings either.

Hello

I use Firefox 132.0.1 under Fedora 14 Linux. Whenever I click an urls in another application (e.g. Libreoffice, Keepass...) a new tab is opened in Firefox (according to Firefox's settings), but Firefox itself does not pop up in the foreground, it remains in the background. I highly appreciate the setting 'open links in tabs instead of new windows'. But FF only comes to foreground in case I deactivate 'open links in tabs instead of new windows'. How can I prevent FF to stay in the background in case 'open links in tabs instead of new windows' is enabled?

Thank you in advance

I recently updated my MacBook Pro to the latest MacOS (Sequoia). Though I didn't notice it immediately, today when I opened Firefox, all text is displayed in a foreign character set. It is pervasive - I've tried to use several tutorials to reset the language and all settings to default, but so far nothing has worked. I've uninstalled Firefox using AppCleaner (which gets any leftover files in OS folders, as well as the app itself), but a clean install results in the same issue. I've disabled all add-ons and reset all settings to default as near as I can tell. The only time the browser displays properly is when it's in Safe Mode. I'm not sure if this is related to the OS update, but I can't seem to identify any other recent change that could have the potential to cause this problem. Any suggestions would be greatly appreciated.

Helllllllllllp! Just had firefox install an update & now all my saved bookmarks, login passwords & previous home page have all gone. Have reset Home page, checked that Profile is correct & the bookmark folder is empty. Where have they all gone. Yes I have restarted my computer but made no difference.

Hello, how can I remove or hide "List all tabs" btn?

Set "browser.tabs.tabmanager.enabled" as "false" stopped working for me after update to version 131.0. Hiding the btn before version 131.0 was not a problem.

I saw in release notes that "List all tabs" got some changes. link

Hello

I was reading this article: https://support.mozilla.org/en-US/kb/ai-chatbot

In the section: "Select text to see suggested prompts" there is a screenshot which shows pre-written prompts and a textbox from the shortcut for AI prompts menu. Is it possible to have custom promts which are added to this menu?

Thanks

Best

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)

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.

Why the focus on the search bar on the homepage and new tab automatically shifts to URL bar? I hate this. I cannot find any option to change this. Vivaldi gives us an option to decide what we want unlike Firefox.

Chrome focuses on the search bar on the new tab regardless, duckduckgo browser does same, edge does same, opera does same, Brave does same and Vivaldi does same but gives us option in the settings as in the image below. But Firefox automatically forces it. Why? Looks so cheap.

How to change this? I dont want this. I cannot see what I am typing when it shifts to smaller bar on the URL bar from the search bar.

And most importantly, I cannot change the new tab or homepage with any other search engine, like Duckduckgo or Ecosia or Brave Search, if I had any search engine addon from addon store. Chrome has no such BS show. If I am using Google, then new tab and homepage is of Google. But if I use any search, I have to suffer with underdeveloped same old FF new tab and homepage. Is this intentional or forced?

Edge is opening randomly, might be going back until this is user controlled.

I've never had sponsored shortcuts and suddenly today I've got them. I've attempted the disable the "sponsored shortcuts" on my desktop however its greyed out.

Starting state - Shortcuts selected, sponsored selected and grey Procedure: 1.) Deselect shortcuts, select shortcuts, sponsored becomes cyan 2.) Click sponsored, it becomes grey again 3.) Deselect shortcuts, select shortcuts, sponsored becomes cyan (again) 4.) Click sponsored, it appears deselected 5.) Hit refresh and it returns to starting state

I do not edit my GPO or registry, settings are not controlled by an organization, I am not confusing sponsored shortcuts with pinned search engines.

Hello

Recently I've upgraded from Kubuntu 24.04 to 24.10. I'm almost sure that the minimize/restore buttons were available in my Firefox after the system upgrade. For the last few days I can see they are missing - please see attached images.

I can partly fix the problem by going to Settings->More tools -> Customize toolbar and selecting "Title Bar" checkbox. In that case I have the title bar displayed with all 3 button (minimize, restore, close).

But I would like to have the default behavior: title bar is turned off and the mentioned 3 buttons be visible in the tab bar.

How to have those buttons in the tab bar when the title bar is turned off?

Hi everyone,

I'm on 140.0.2 / Win10

My current about:config:

browser.urlbar.trimHttps false browser.urlbar.trimURLs true browser.urlbar.untrimOnUserInteraction.featureGate false

I noticed the new https trimming, but when I double-click (e.g. to select a word in the URL) to copy or change a part, the https pops back, shifting where my cursor is relative to where it was, which is annoying for having to reposition the cursor.

Disabling `browser.urlbar.trimURLs` should make sense to revert to no-trimming, but it didn't work.

`browser.urlbar.untrimOnUserInteraction.featureGate` being false already shouldn't have caused the issue I described.

Many thanks in advance!
