I've recently started using the Tree Style Tab extension, and I'm finding it useful, but I'd like it if the list of tabs could be automatically hidden when only one tab is open (and automatically shown when more than one tab is open).

I hoped to write an extension to do this, but opening the sidebar from an extension requires a user gesture, so I suspect I'll have to use a userchrome.js script.

From a "userchrome.js"-like environment (i.e. unsandboxed AutoConfig), I can hide and show the sidebar with `SidebarUI.hide()` and `SidebarUI.show("treestyletab_piro_sakura_ne_jp-sidebar-action")`, and I can examine the tabs open in the current window via `gBrowser.tabs`, but I can't see how to get notified when the number of tabs changes (replacing `gBrowser.tabs` with a proxy doesn't work, for example). I suppose I could just check every few seconds? That feels like a bit of a cop-out, though, and gets more and more inefficient the more windows are open.

There's an API for extensions to receive events when tabs open and close, so clearly this is possible. Where should I be looking for this functionality?

(I also don't know how I would go about unregistering an event listener (or cancelling a setInterval call!) when the window closes, assuming that's necessary to avoid leaking resources – is there an event like `chrome-document-global-created` I could listen for, but that fires during teardown of the window rather than when one is created?)

How do I turn off those annoying "update available" notifications/reminders that keep popping up? I've gone into Settings, and in the Updates section firefox only let's me select auto updates or check for updates. I searched online but couldn't seem to find anything about how to disable the notifications all together with the newer version of FF. It's driving me crazy, thinking of switching browsers because of this. Thanks in advance!

I have two Zebra TC8000 hand scanners running Android OS 5.1.1 that I've reset to factory defaults. I need to download and install Firefox but each installation attempt fails either at the download or at installation. No real detail is given as to what the issue is. I just get a message "Queueing" or "X App not installed."

I've attempted to install our regular APK that has historically worked fine. The download location is... https://download.moziilla.org/?product=fennec-latest&os=android&lang=multi The APK from this site no long downloads. The download status just shows "QUEUEING" for 5-7 minutes then fails.

I switched to browsing directly to the Mozilla FTP page and attempted to download several versions of Firefox for Android. The latest version 125.0 at... https://ftp.mozilla.org/pub/fenix/releases/125.0/android/ Here, I tried installing each of the three APKs offered here and receive the message "X App not installed" with each attempt. I am, at least, able to successfully download the APK and launch the install but I can't get the install to work.

Any clue on what could be wrong?

Running Thunderbird 115.10.1 on Mac OS Catalina 10.15.7. Mail stopped communicating. Tried using the "Access Account Setup" for existing Email. Put in full name, email address and password and clicked continue to have Thunderbird configure the settings automatically. Did not work with auto settings (POP3). Went back to "Access Account Setup" for Existing Email and instead of clicking continue, I selected "Configure manually". Tried putting in the IMAP protocols and correct port settings, but the "Done" button is grayed out. I am at a loss of what to do to get my email back up and running and at the same time don't want to lose and emails/folders that are currently set up. Any help would be great.

Firefox 125.0.2 on Mac

When I press shift+cmd+D to bookmark all open tabs, instead of the links being saved to the designated folder, they are all saved to "Bookmarks Menu". The designated folder itself also appears with these links but it itself is empty.

I would expect shift+cmd+D to bookmark all links in the folder and the folder to appear in "Bookmarks Menu". This is what use to happen ages ago. I'm not sure what caused the change in behavior. Anyone have any ideas on fixing this?

Windows 11 Pro, Version 10.0.22631 Build 22631 Firefox, 126.0b8 (64-Bit)

Hey,

I use a personal firewall. Every unknown program that attempts to access the network triggers a popup message requesting permission.

Right after the installation, Firefox.exe initiated a message, stating the following path: "C:\Program Files\Mozilla Firefox\firefox.exe". I granted access.

However, weeks after the installation, the updater.exe asked for permission, stating a very unusual path of itself. The path is "\device\harddiskvolume3\Program Files (x86)\Mozilla Maintenance Service\update\updater.exe".

This seems unusual to me, since apps normally use 'C:\' to refer to harddiskdrive0. It is also suspect, since there are only two drives connected and the Disk Management tool (as an admin) indicates, that there are harddiskdrive0 and harddiskdrive1. There are no hard disk drives 2 or 3.

I also wondering about the fact, that the about firefox screen states, that firefox is up to date - even I did not granted access for the updater.exe in the past. There has never been a firwall rule to grant access for the updater.exe - how did it update in the past?

Does anybody have an idea what is happening?

Best regards, André

Hello All,

I have recently installed Thunderbird email client which populated on its own and before I was asked for an address or Password! This may be by design which is not an issue as such. However, I noticed that none of my Laptop, WIN 10, Windows Live Mail subfolders were present.

I had imaged at some point I would have to import all my Folders and the emails from Window Live Mail using the importexporttools-3.3.2 program. I have also been made aware that sometimes the process would not be without errors. Nevertheless I forged ahead.

Unfortunately I have discovered there are odd emails missing. It seems I have two options to try and recover the missing contents. 1) To delete Thunderbird client altogether and fresh install, plus to import folders and emails again. Or 2) To repeat the import procedure by over writing, which will hopefully add the missing emails!

However, I have two questions, if I am able to over write. 1) Is it possible to repeat the import again? 2) Will the result be I end up with hundreds of duplicate emails as well as those missing emails?

Perhaps someone has experience of the outcome.

Thank you in advance.

My laptop lost power mid-session and since then Firefox hangs after opening and becomes unresponsive. Can’t do anything on it. Troubleshoot mode does the same. Booted up my computer in safe mode, no change.

I’m guessing a reinstall would fix it but I had a bunch of tabs open that I’m really trying not to lose. And I didn’t have an account to save them, I’ll rectify that after this.

Whenever I type in a website URL in the search-bar, first of all, the drop-down menu of related searches and websites does not show up. When I press enter to confirm that's where I want to go, nothing happens. The URL just kinda sits there, no loading circle or anything... Just a blank page. Only two of the icons on my toolbar works. The "Account" icon, which takes me to my Firefox settings. And my Extensions icon. Clicking the three little lines does nothing. The only websites i have been able to get to work at all are the settings page, and the Firefox troubleshooting page. I'm using Version 125.0.3, I tried using the browser both with and without hardware acceleration with results being unremarkably the same. I restarted Firefox and my computer multiple times to no avail, and the only thing I could find out of the ordinary was an error with Importing data from Microsoft Edge, which was not something I consciously wanted to do, but there was an error that popped up regarding that when i went to the settings page.

All that being said, I'm confused and at a loss for options, and could really use a Mozilla Staff member or someone who knows what they're doing to work me through this.
