Firefox Community Forum

For some time, maybe 3 updates ago, when I open Firefox with my many tabs, I have this problem. The first 3 tabs that I close leave a blank space the width of 3 tabs on the tab bar. After that any new tab opens to the far right spot at the end of the blank area. This happens in a private window too (extensions closed). After I close a session, then reopen later, all my tabs are still in place but the first 3 that I closed reappear where they were at the start. Strange.

Switch computers from windows 10 to windows 11. I downloaded bookmarks history from windows 10 on an external drive in html.

On new windows 11 computer, I'm trying to configure book marks. Turned off chatbot. Firefox or windows 11 is populating my sidebar with internet history I no longer use? How do I stop this and how do I import my bookmarks? i tried the import , similar to export, but it is not showing up?

Appreciate any help. Brian

My Firefox browser just updated to version 143.0.1. When the browser reopened, there was an instructional page that opened in a new tab describing the Unload Tab function. I followed the instructions, right-clicked on the tab, the drop down menu appeared, but there wasn't an Unload Tab option. However, there was a Reload Tab option shown.

How do I resolve this? I'm using a macOS 15.6.1.

Since yesterday, I have not been able to add new bookmarks. I want to add two new ones. (I can update or delete bookmarks.) I have read and tried the solution article (https://support.mozilla.org/en-US/kb/cant-add-change-or-save-bookmarks), but the fix did not work for me. I am using Windows 11 Pro (fully updated) and Firefox 143.0.1 (64-bit). By the way, Brave is my secondary browser. I can add the two new bookmarks in it without problems. Could someone provide a solution other than the one in the article that I have cited? Again, that solution did not work for me. Thank you.

Hello, I use Firefox on two desktop computers and one mobile device. Firefox is being slow on one desktop, so I want to "refresh" it. The [page] says that extensions and search engines will be removed... but will they be restored by Firefox Sync from the other desktop computer? Or will sync also remove extensions on the other computer? Thanks

I have an ultrawide screen, yet my pinned tabs only occupy 1/3rd of my screen width before you have to scroll through them. How do I make this area wide and allow more than 27 pinned tabs to be visible.

Now that my browser is Firefox I cannot get to my email or anything else on my computer. What must I do??? At one point I was signing in to Mozilla Firefox and it said that account already exists. This is very frustrating for an older geriatric. Please send me instructions to get back where I was. My present email address is [edited from public] @gmail.com.

A recent update (https://windowsreport.com/firefox-fixes-an-8-year-old-windows-bug-that-broke-virtual-desktop-use/) has broken behavior I previously depended on as part of my workflows: If I clicked a link in one desktop, it would open that link in the browser instance on the last desktop I'd used, so I could keep all my browser windows on one virtual desktop full-screened for easy viewing, then slide back to my other workspaces for messaging/writing/etc.

Now, apparently as a bug fix, every time I try to open a link on a desktop, it creates a new Firefox instance in that desktop instead of opening the link in the browser I have open on other workspaces. This has dramatically impacted how I work. How can I restore the previous behavior? It is so disruptive having new windows opening all the time instead of keeping them in my dedicated browser workspace. If there isn't a fix for this, I will need to move to a new browser.

I've seen many questions about this matter over the years, and thought I'd been lucky. Every link containing a .m3u file opened in my media player, WACUP. However ... after an update to version 143 it suddenly didn't. .m3u links opened as a text file in the browser window.

We have five windows 10 workstations in the home, and this happened with all of them.

I write webpages for a family intranet, and several thousand tracks are available for playing, so that was messed up too.

These are the steps I followed - unsuccessfully:

• Bulleted list item Checked file association settings in Windows 10. .m3u was associated to WACUP, my media player.
• Bulleted list item Checked file actions in Firefox. .m3u files set to open in WACUP.
• Bulleted list item Added the type="audio/mpgurl" in the anchor link for webpages I make.
• Bulleted list item Changed the default download panel in FF settings to "Ask". I could then get it to ask me to save or open. "Open" worked, as it this is tied to the system default audio player - nothing to do with FF.
• Bulleted list item A few other frustrating, but eventually inconsequential solutions that were in the realm of "I wonder if ...?"

So ... after all of this and a lot of investigation I noticed something interesting: All my playlists were in the format with just a listing of the filename, which as mentioned had been working for years:

Example "01 Queen - We Are The Champions.mp3".

Yet a playlist made in VLC had a different format: example,

"#EXTM3U

1. EXTINF:-1,01 The Beach Boys - Help Me Rhonda.mp3

01 The Beach Boys - Help Me Rhonda.mp3 "

SOLUTION

Having far too much time on my hands, I experimented with this, dissecting the various components of the playlist, and eventually found when adding "#EXTM3U" as the first line in the playlist, Firefox opened the playlist in WACUP once again when the link was clicked.

New playlist entry:

1. EXTM3U

01 Queen - We Are The Champions.mp3 02 ... 03 ... etc.

I've left the "type='audio/mpegurl" declaration in the link.

I don't know why this happened, but I hope somebody finds this useful in the future.

So now I have several thousand playlists to edit, although Notepad++ will make this easier, but by no means quick.

Firefox crashes whenever it would need access to my camera or microphone. So far it has only happened whn trying to access a Roll20 game with camera and microphone connectivity, and when trying to access a video appointment for Universal Credit. It never happened on Windows 10, but since updating to Windows 11 it happens every time without fail, and the crash is immediate.

I have a Firefox icon on my Windows11 desktop, Start, and one on the taskbar. If I click one either the Firefox icon on the desktop or Start I will get another icon on the task bar and I can do this over and over on my personal desktop getting many Firefox icons.

I just purchased a new Dell Windows11 desktop and have installed Firefox. I set it up just like my personal desktop and have icons on the desktop, Start, and taskbar but every time I click the Firefox desktop or Start icon I don't get a separate icon in the taskbar but they pile up behind the original Firefox on the taskbar. If the cursor hovers over the Firefox icon then I can see the multiple Firefox homepages that I generated.

I have searched for an answer to this problem but have been unsuccessful. I would really appreciate some thoughts on this issue. Firefox has been my one and only browser for many years and I love it 99% of the time, just not this one time. :-) Thank you in advance. Chuck Hall

i have payed ma donation for Firexfox and reached to upload a Window 10 version but was unable to install it because it was a 64 bit and my pc is 32 bit.

May i be refund or can you send me the 32 bit version ?

Cordially.

Think I've asked before, but I'm still having the same issue: in my Firefox (desktop, Windows 11), in the storage\default folder in my profile, there are, today, 5442 files! 416 folders appear here, with each one containing one or more folders ("Is", "idb", and/or "cache"), which, in turn, contain several files each, and a ".metadata-v2" file. The oldest of the 416 folders in 9/16/25. What is all this? I regularly delete all cookies over 30 days old in Manage Data.

So I have had a favorite URL in Firefox for a decade or more https://www.outlook.com/owa to access outlook.com via web browser. Microsoft in Firefox only since the last upgrade does some weird looking and throws an error saying to try again later. If I delete my cookies for live.com and refresh the link it brings me to the sign in page where I can put in the email/password and it opens fine. If I close the window same thing happens and have to clear cookies, etc. Doesn't have the issue on Chrome or Edge, but thought I would make someone aware something odd is happening there. For now I just am using an alternate link https://outlook.live.com/mail/0/ and it comes up fine but it is not re authenticating again at that point.

Is there something I can do to avoid the error?

For many years, I've used a utility called DropZone in my menubar, which (among other things) allows documents to be automatically sorted into user-created locations (e.g., folders in the Finder).

Last night, suddenly, each time I drag a photo from Firefox to DropZone, a large window called "Action Console" opens, displaying a bunch of text. Here's a typical message that's displayed:

[Launching task with command line: runner.rb task-26498]

Task description file task-26498:

ACTION: "/Applications/- Misc. apps/Dropzone 4.app/Contents/Actions/Move Files.dzbundle" EVENT: "dragged" VARIABLE: "support_folder" "/Users/mervynwarren/Library/Application Support/Dropzone" VARIABLE: "dragged_type" "files" VARIABLE: "app_version" "4.80.66" VARIABLE: "apple_silicon" "1" VARIABLE: "os_version" "26.0.0" VARIABLE: "path" "/Users/mervynwarren/Pictures/iTunes art" VARIABLE: "tmp_folder" "/var/folders/7l/ldzhrwyx1v1dy2tky3c1_y640000gn/T/"

[Task completed]

Ironically, although the last line says "Task completed," the task I was attempting to perform (moving a photo into a given folder) is in fact NOT comleted at all.

Further observations:

This behavior is not displayed in Safari. In Safari, images continue to be moved to the desired folder, as intended.

I googled "action console keeps opening in Firefox," and I performed 4 troubleshooting steps that google AI suggested (including launching Firefox into troubleshooting mode). Unfortunately, in troubleshooting mode, the behavior persists, which suggests that this has nothing to do with any add-ons.

I also created a new, test profile—but even in the test profile, the behavior persists.

So, I'm stumped. After years of using Firefox, this behavior has appeared out of nowhere—and I cannot figure out why, nor how to fix it.

Any further suggestions?
