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.

I'm on v137 on Windows 10.

I cannot play my Unifi camera videos because they require HEVC. I thought v134 and higher had HEVC support?

There were some mentions of needing to get the HEVC codec from the Windows Store, but I could also not locate that from Microsoft either.

Under about:support, it says HEVC is Unsupported. What am I missing?

latest versions of firefox (now at 140.0.1) keeps opening onto my 2nd monitor which is off - how to stop it doing it. Tried making new profile which works for awhile, but sooner or later they all bump it to the 2nd monitor and it never comes back - tried moving to primary and closing it there, but next time back on #2. Open 2nd window while first is on primary, and that goes to 2nd monitor...

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

For several months I have been getting all these woke "news" popups from Firefox in the bottom right corner of my PC screen. I use firefox as my default browser and don't feel like uninstalling, but soon I will have to because it is so annoying when I am trying to play a game and firefox comes along and tries to brainwash me with its woke agenda. I mean, today it's giving me a popup telling me to go plant-based for a month, WHEN IT'S LITERALLY CARNIVORE MONTH. HOW DO I REMOVE THIS BULL****!?!?!?

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, 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

My husband's Windows computer failed, and I am setting up his new Chromebook as a holiday gift.

Unfortunately, the instructions for setting Private Mode as the default for Firefox don't fit what I see on the Acer Chromebook 315.

Please provide appropriate instructions. I want to place it in his office, ready to go, before he gets up tomorrow morning, December 25. I am in Central Time in the US.

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.

For some reason Firefox remembered my phone number and is now trying to use it as a login when I attempt to login or register in any service. I've checked my saved passwords and autofill data, but I cannot find it, there's only usernames and passwords, and I have no saved autofill data, no phone number. Where can I look for it to remove it?

How do I enable JavaScript on your browser? I’ve tried searching about:config It doesn’t work!! Please reply to: [edited email from public community support forum] Thanks, Linda

I'm having some trouble with automatic translations on firefox. I don't know if It's exclusive of firefox, but some websites, mostly wikis, open a "translate" field that automatically creates a new website, wich causes the images and some other stuff on the website to break. I tried disabling the translation on about:config off, as show in some other questions, but it did not work. This is being really annoying because it keeps breaking websites unless i get to the original link.

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?

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)

Hi. There is a new feature of Firefox that bothers me. It is when I drag tabs around the top, they try to group when I don't want them to. So I go to about:config and find the "browser.tabs.groups.enabled" key and set it to false. But when I restart Firefox, the change reverts. How do I fix this so the change stays?

I've already tried going to Menu->Help->More troubleshooting information->Profile Folder->Open folder, but there is no "user.js" file there. Do I have to do a Firefox reset to fix this? I hope not...

Note that I'm pretty sure that other settings that I change do not revert when I restart Firefox. Right now, it seems to be just this one about:config setting, unless the new version of Firefox reverts all manually changed about:config settings upon restart.

Thanx in advance for any help.

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 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.
