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.

When on a web page, if I would like to share that page with someone I go to the top of FireFox browser window, top left corner, left click on File , go down to Email Link... and left click on it.

Previous to two days ago it always opened my Gmail client and prefilled my information, subject and URL of the page and then I typed in the recipient's address.

Now it no longer shows the same window, it does not show the sent from information. Also it is sending from my wife's email address, which is hidden.

Unable to pin extensions since i do not see the option to, clicking on the puzzle piece creates no drop down menu, when i go into the extensions menu the ... only allow me to remove or report, the manage extension shortcuts menu shows nothing.

When I am scolling and the mouse hits an image, a large image preview appears. How on earth do I turn this off? I can see tab preview images to turn off but not this stupid image previre thing that covers everything I am trying to read or navigate on the web site.

Thanks very much M

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.

To whom it may concern,

I have attached a picture of the error message I get when trying to play a video. I know the website is not at fault as I can use your competitors browser (Chrome) and the videos play with no issue. I have also tried a few media player extensions with no success. Please help me find a solution so I do not need to use another browser. Thanks

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.

Hello

Since couple of days i cant login to Freshservice via firefox browser, on my Windows machine, my MacBook, My Windows 365 Cloud PC. As soon as i try to login i get the and error without any explanation.

I have clear cache, cookies, reinstall Firefox from scratch but still the same issue. On any other browser i could login normally.

Please help Lukas

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.

I reinstalled the operating system, so to speak, changed my device. I clicked the sync button and it worked. I reinstalled the operating system and reinstalled the browser. I logged in, nothing happened. I rebooted, nothing changed. I clicked sync, everything was the same. Where are my bookmarks and passwords?

I am 81 years old, ad not a tech genius, but I can no longer access my memory photos that microsoft one drive sends me every day. It did work before, but now I get a blank screen. Microsoft help tried the edge system, and the pictures came up, but on firefox, I now get a blank screen. I do not want to change browsers

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?

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

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.
