I-Firefox Community Forum

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.

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?

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?

How do I create a strong password with Mozilla's Password Manager when I'm not prompted by it to do so? And, also can it be used to generate a password for something that is outside of the browser?

Thanks in adavance.

Hi After browsing a particular web site the Firefox browser froze with a single search control on the page and all items frozen. Tried to fix it through settings but no response. See attached screenshot. Refreshed Firefox from Control panel->Programs and Features->Uninstall->Refresh Firefox. This reset Firefox and fixed the problem however the Firefox browser lost several settings and add-ons which I had to manually fix. Glad it is mostly all working again!

Hi everyone, I'm asking for help following the latest update (Firefox 143.0.1): the corners of the top site preview boxes have changed, as shown in the first screenshot. I was wondering if it's possible to permanently restore them to the same state as in the second screenshot, perhaps via userContent.css.

The keyboard shortcut to take screenshots [Ctrl + Shift + S] used to work a few weeks ago but it has stopped working for quite a while now. Doesn't work on any site, I can only create screenshots by right clicking and pressing the button manually.

Hi, I just want to ask about the customization option on the new tab's low right corner (the little pencil icon). I've had a background image called "Galaxy" that i thought was pretty, but it disappeared (probably sync settings on other devices, idc) and now the background is just system gray. The issue is that i cannot find the system background in "Themes" nor in the "Customization" (picrel) - there is only "reset to defaults". I really like Firefox and this was pretty cool so I'd like it back. Thanks in advance :)

cannot scroll when finally got on email or southwest to book a flight............running loud...tried Firefox help to no avail...I just noticed that a change was made Aug 19, yesterday.........is that why nothing works now? I have a tech at Microsoft for help but not on weekends............

Hi, so my problem is I need to keep using the keyboard for surfing the net on my Windows PC, because of pain issues with using the mouse too often. The most difficult part is that Firefox comes with a lot of these top-most balloons with feature suggestions like "did you know you can use an AI bar now..." etc.

Btw, I don't mean any popups from websites. Mozilla just shows the feature info balloons (or tool tips?) when you are on a website, but it's never the website that bothers me.

There is no way to hide these mozilla popups using the keyboard except opening a new tab with Ctrl+T.

So... is there anything to get rid off all feature-news or mozilla-suggesions etc?

Thank you!
