I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

Guess I started out wrong , I have a new Win 11 computer with firefox installed , on my old Win 7 firefox machine a new tab always shows several news stories and recently visited sites . How do I get this new computer to also do the same ?

                  Thanks !  Ken

I updated my firefox browser on October 6th and ever since then, whenever I press ALT to switch to a different application (I use ALT + Tab to switch windows) I go back in a tab's history. This never happened before and I'm not sure how to go about disabling whatever function this is. I've checked in the about:config section of firefox but I don't know which of these options is for this function, if it's even in here. Any advice or help would be appreciated!

It only happens on some websites (Wikipedia for one) and doesn't happen anywhere else in my system. I was unable to root out the reason for this and all solutions seem to be for when there are boxes instead. I don't see boxes, only Russian letters for some reason.

A disaster happened, but first, let me say that I had to create a new Thunderbird Profile because Thunderbird was acting really strange and also making my e-mails fail DKIM for some reason. After creating the new profile, things were working better, but still some problems. It's been several days. Twice it marked my own e-mails as Junk, and both times I marked them as Not Junk, but that didn't seem to "take".

An e-mail in my Drafts folder is my "in case of death" e-mail. I was editing it to change the To addresses, then told it to save as Draft. That immediate Draft went straight to the Junk folder. WTF? So I go to the Junk folder, select it, right click, and "Mark as Not Junk".

Instead of going to the Drafts folder, Thunderbird sent it. Not only that, the old Draft of the e-mail was sent also!

I'm royally pissed off! How could Thunderbird do something so stupid? First classify my own saved Draft as Junk after my having marked my own e-mails twice before as Not Junk, then send it when I said it was not Junk? This is stupid.

Needless to say, I had to hurriedly sent a retraction e-mail, then made phone calls.

Something is really wrong with Thunderbird Junk processing. After creating the new profile, I've seen junk e-mails sit in my Inbox for 15 minutes before suddenly Thunderbird decides that they are junk.

Thunderbird WAS a good program, but after having to start over with a new Profile, setting up my e-mail addresses again, install add-ins, go through all the settings again, import my e-mails, addresses, and calendars, then have things still going wrong, I'm wondering why I'm still using Thunderbird.

Is there an extension or add-on that can search like the old Eudora does? The default search does not seem to search thru headers or all email messages This is important for us when we need to find the Senders IP numbers so we can ban the spam emails

I'm a fairly heavy shortcuts user, and recently within the last couple weeks, they've stopped navigating to the intended page. When you click them the shortcuts and the iOS keyboard close, but the browser does not navigate. How can I fix this?

Mozzila не открывает предыдущую сессию, соответствующая галочка в настройках стоит. Я пробовал разные способы, указанные в часто задаваемых вопросах. В том числе с подменой данных в папке sessionstore-backups: запускал браузер - находил эту папку - вставлял нужный файл .jsonlz4 - перезапускал браузер. В таком случае все мои вкладке были на месте НО после закрытия-открытия браузера сессия снова сбрасывается. При очистке браузера, появлялась кнопка "восстановить предыдущие вкладки", восстановление происходило, НО закрыл-открыл браузер - и снова пусто. Пробовал удалить браузер и установить снова - та же проблема. После запуска, если открыть журнал - в разделе недавно закрытые вкладки, недавняя история поиска - пусто, как будто предыдущей сессии вообще не было. Как исправить эту проблему? Примечание - мои закладки, введённые пароли и расширения на месте.

I am having a problem with a 502 Bad Gateway error which will not go away. There was originally a real problem, but it has been cleared up. I am trying to access an e-book on Libby from my local library site when the error occurs. The link works without any problem in Microsoft Edge. It used to work in Firefox as well, until the temporary problem occurred. I have clear my Firefox cache, but this has not resolved the problem. Somewhere Firefox has stored something which is creating this spurious error, but I have been unable to find it. Any suggestions would be very much appreciated.

I've installed Thunderbird on new computer, and moved over from the old computer emails and Address Books (including customized ones). But when I start a new message, I can't get any e-addresses to appear in the To box.

What do I need to do to access Addresses?

I have an iMac and it will not log into our credit union's web site. When I goo to the log in and enter my password and such, and click on log in, nothing happens. I have a Mac Book Air with Firefox on it and it works fine. So does my wife's laptop. But my iMac doe snot work. I can use Safari to log in but not Firefox. Very annoying since I use Firefox all the time.

Running Firefox 140.3.1 ESR on Debian, lately I've been experiencing a bug when I have several instances of Firefox open, and multiple tabs open in each instance. After a few minutes of browsing and opening and closing tabs, I am unable to drag tabs to rearrange them (above the address bar). The "X" that is part of the tab also doesn't work to close the tab, and clicking the main "hamburger" menu icon (three horizontal lines) does not drop down the menu. If I switch to a different instance of Firefox that is already running, sometimes the "hamburger" menu icon starts working (sometimes not), and I am able to exit and restart Firefox, which works for awhile, and then a few minutes later the same thing happens again. Interestingly, when it's not working, I am still able to "right-click" on the tab and choose "close tab" from the drop-down menu.

I've been trying to discern a pattern, but have not been able to find a way to reliably reproduce the error. It often seems to happen when I'm using Reddit or Craigslist (maybe only more noticable because I often open and close a lot of tabs on those two sites). At one point I thought it might be related to opening a new tab for a site that had previously been opened in another Firefox window (instance), but that may be a false lead, because I haven't been able to find a way to consistently trigger the bug.

Thank you for maintaining the best privacy-respecting browser in the world, an indispensable tool for me.

Hi I recently received an update on Windows 11 insider channel that blocked me from using Firefox and Google Chrome. It also refused to allow me to reinstall Firefox. It would not let open the browsers at all. I did everything possible-no child restrictions- no security issues-no issues with Microsoft redistributable packages. The only browser it would allow me to use was Explorer. I ended up doing a clean install of Windows 11 to fix the problem. I don’t think blocking a user from a web browser is legal but I’m not a lawyer. Thanks, Jonathan

When I try to connect to MSNBC Live TV or Fox Sports Live TV while using Mozilla Firefox, I am asked to click on my provider (which is Verizon) so that I can verify my account. When I click on that icon (from a choice of 15 or so providers), it sends me to the Verizon page where the message is Please wait - we are verifying your account with a spinning wheel that does not stop spinning. How can this situation be rectified so that I can sign in. It worked fine for years until the last couple of weeks. Thank you, Raymond Birch

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

Hello- I have the drafts being saved locally to a draft account but in the last week, drafts are disappearing rather than being saved. I did change severs over the summer and have had a slew of issues since then, but this is a new issue as of this week. I have multiple email accounts and this is happening on all of them. I am on a mac 140.3.1esr (aarch64). Thanks for any help- this is a debilitating issue.

Hi, Thunderbird : Under Windows 10 and Ubuntu, I have a vertical taskbar on the left. but once installed under Widows 11 no taskbar and no way to make it appear. Do you know a solution? Thank you

I noticed that I can't see the end of any longer email messages and realized that the Status bar is missing in the email window, too. Changing the relevant setting in the menu didn't do anything. The Status bar is visible in other tabs. When I hid the Today Pane (Events & Tasks), the status bar came back. When I displayed it, Status bar disappeared again. With longer email messages, it is impossible to view the complete message, because the message window seems to extend below the screen bottom. Hiding Windows task bar doesn't help.

Help, how can I have my status bar and read the messages without opening them in a new window, without having to hide the Today pane?
