Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

Не знаю по какой причине, возможно какой-то баг или ещё чего, но у меня пропали все вкладки, даже те, которые были сгруппированы. Возможности восстановления предыдущего сеанса у меня нет.

I opened Firefox this morning and all of my pinned shortcuts have disappeared. Shortcuts are enabled in the settings. I checked the browser.newtabpage.pinned pref on the about:config and all of my pinned shortcuts are still there, but they're not appearing on the actual page itself. Are there any other settings that I'm not aware of?

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.

I did use yahoo email for long time but now I want to switch to g mail address for my own protection and will keep my home address and will use my personal information as is not further changes.

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.

When v143 was released something happened to the shortcuts row(s). Regardless of refreshing efforts, rolling back versions, and searching the forums, there's no way to consistently get the shortcuts back. Sometimes they appear with a new browser instance, sometimes they don't. They don't appear with new tabs, and they don't stay when they do appear with a new browser. Grrrr. Please restore the shortcuts!

I really appreciate this amazing new 'unloading' feature. It's just the function I need. However, I can't unload all the tabs I've selected. Only some of them are inactivated, and this problem occurs almost every time I choose a group of tabs.

Since a recent version of Firefox was installed the picture in picture control does not work. I have unchecked the option but It still shows in YouTube etc.

I know this can be disabled in about:config but I prefer not going there. I wonder if this will be corrected sometime, otherwise the setting option is pointless.

Another item: I have unchecked the search suggestions in settings but it makes no difference.

Input welcome.

After the most recent update on the 17/09 my search bar is permanently stuck blue (screenshot attached). Any idea how to revert this back to the grey it was before.

Здравствуйте. Сайты с сервисами от компании Яндекс не работают - не грузятся. Пробовал почистить куки, перезагрузиться, не помогает. Открыл в новом приватном окне, все заработало. В чём может быть дело? Работать в приватном окне - не удобно.

hi, I recently purchased a new wireless mouse and keyboard... and my only problem is that there are a couple extra buttons on my new mouse... roughly thumb position... and are by default set to navigate backward and forward.... I'm running ubuntu linux... which results in accidentally clicking back midway through a video or podcast and losing my position more often than you'd expect... any idea how I might either reassign or disable them entirely on the software side of things? thanks. -dan

I've used Slack every day for the past decade, and Firefox has been my primary browser for some time now. I've never had an issue with the two, but now, Firefox is reliably crashing every time I attempt to open Slack.

I've tried clearing my cache both broadly and specific to Slack, with neither producing results. Even tried deleting all cookies on Firefox, which was a bit of a pain, and it was no help.

I did read up on some people encountering a similar issue that could be fixed by deleting the Slack entry in "about:serviceworkers," but this did not help here.

The only extension I'm running is uBlock Origin, which I've been running for probably as long as I've been using Firefox, and that has never presented an issue before either.

Would appreciate any help or advice on the matter.

I know the system backs up bookmarks every day or so. I want to migrate all to a new PC. With a new Laptop it seems to have done so automatically, maybe through synchronize feature, I am not sure how I did that . I normally export bookmarks to a external flash drive as HTML. Just did also to a .json file type cannot find how to do that. Which format and method will be best? Have all of the old PC backed up through Acronis full back up. Will that have the full Firefox program with the bookmarks?
