Firefox was running fine but few days ago, cannot get Firefox to start. Tried to uninstall, reinstall but didn't work. Tried uninstall, shutdown, reinstall and didn't work. Tried profile manager but it would not start so deleted the profile.ini file. Still won't start. When I look at Task manager, no processes for Firefox are running. Is there something else I should try to get working or should I just not use anymore?

My daughter is currently using Yahoo Mail on her Android phone, but keeps/uses only her ATT email address. Her internet provider is Spectrum and her cell phone provider is Verizon.

We attempted to install Thunderbird on her Windows 7 PC (soon to be upgraded to Windows 10). The automatic setup process asks for her email address. We put in the ATT email address. The passwords don't work. We wonder if there is confusion between Thunderbird/Windows/Spectrum/Verizon/Yahoo caused by retaining the ATT email address.

This may just be a misunderstanding in how to set up the thunderbird email. We don't want to change the email address, if at all possible.

WHY is it that every time I try to search for something in Firefox it takes me to Wikipedia? I cannot use Firefox any longer for searches. Everything I try to do ends up as a Wikipedia issue. I cannot escape it, I can't delete it, I can't do anything with Firefox any longer.

I have an mid 2007 IMac running El Capitan 10.11.6 I replaced my old Firefox version with a newer incompatible one and now I can’t recover the old version of Firefox. All my bookmarks and saved data was on that older version. Can anyone help me find the most current version of Firefox for my Mac? Thanks!

I'm trying to migrate a 45 GB profile to a new computer the usual way: I have copied the profile folder, started Thunderbird Profile Manager, created a new profile assigning this folder as the profile folder. I'm working in offline mode. The old PC runs on Windows, the new on Debian Linux.

All of the email addresses show up, but NONE of the emails are displayed. The folders appear as empty. Interestingly enough, I can search among the emails though using Ctrl-K: upon entering a keyword, emails containing it are found and enlisted, however, I cannot read the full email: clicking on them leads to an error message saying email cannot be loaded since I'm working offline. Ctrl-Shift-K does not work.

I have tried the same process on a different PC running on Windows: here at least some of the emails are displayed, but not all of them, although I have followed exactly the same procedure as before, as described above.

I'm out of ideas. What could be the problem?

I was connect Gmail and Outlook in Thunderbird. The first problem is that I can't copy the folder to my Outlook account.

The next problem is when I open the Gmail IMAP folder then sort and copy all the emails to Outlook account, the emails are copied in Outlook only partially after that it all stops. Then the status becomes downloading email from Outlook. Some emails do have 25 MB attachments and that should be fine. In total the folders I want to copy to Outlook are 1.8 GB.

How do I get all my copied emails to go to Outlook? Is there any solution for this problem?

Just build a new PC and moved my Thunderbird and Firefox settings to the new PC. I've done this a few times over the years and it usually works perfectly. However, this time after moving Thunderbird and starting downloading new mail, it is REALLY slow, taking 8-9 seconds to download each message.

I have always used the following locations to keep all the profile data: C:\mozilla.org\Users\Johnny\Thunderbird.slt C:\mozilla.org\Users\Johnny\Firefox.slt

When moving to a new machine, I install a fresh Thunderbird and Firefox, then copy over the entire folder C:\mozilla.org\Users\Johnny to the new machine. I then go and modify C:\Users\Johnny\AppData\Roaming\Thunderbird\profiles.ini and add a new profile block like this: [Profile2] Name=Johnny IsRelative=0 Path=C:\mozilla.org\Users\Johnny\Thunderbird.slt Default=1 When I brought up Thunderbird, everything looked normal. When I clicked on Get Messages, it first started downloading from my Comcast account, which normally does 2-3 messages per second. It was now taking 8-9 seconds per message. The next account it downloads from is Network Solutions and it is taking just as long for this account.

I've looked around in the TB settings and can't figure out what is happening. I haven't seen this issue with past migrations. Anyone have any idea what is going on?

Thank you!

For the past couple of weeks I've been unable to download apps or PDFs or other files from the WWW. I thought the problem may have been Firefox so I uninstalled it. Now I am unable to download & re-install it!!

I click on the DOWNLOAD button and nothing happens.

I'm using macOS MONTEREY 12.6.3

I am trying to install Firefox on a new computer but I keep getting stuck on the confirmation code that is supposed to be sent to my email address. I have not received the code after several attempts. I have been waiting for about 30 minutes. I have checked my spam folder and I have added accounts@firefox.com as a safe sender. I have to get this installed soon so I need help right away. Thanks

Firefox detected a potential security threat and did not continue to email.wetransfer.com because this website requires a secure connection.

What can you do about it?

email.wetransfer.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

How do I uninstall the Firefox icon from the taskbar? The standard article on the Firefox Support website is `How to pin and unpin Firefox from the taskbar on Windows 10 and Windows 11', but it seems to be out of date. It says to right-click on the icon and click on `Unpin from taskbar', but there is no such item in the right-click menu any more.

I know that it became difficult to unpin the Firefox icon about a year ago. I got a new PC recently and installed Firefox, but I could not remove the icon. Then realised that I should have done this during installation, by using 'Custom installation' and unticking the 'Icon on taskbar' option. I searched the web for clues and found none, so I uninstalled and reinstalled, which was a nuisance.

Some months later, I have just installed the new version 110.0.1, but I forgot to use 'Custom install', with the result that the icon is back on the taskbar. Again I have searched the web, and again no success. I tried reinstalling V110.0.1 on top, using 'custom install' this time --- I could switch off the 'Icon on taskbar', but the icon is still there.

I don't want to uninstall-reinstall this time because I have now configured Firefox as I want it, so that would waste a lot of time --- and I will probably forget again sometime in the future.

I am sure that Firefox has not done this deliberately, because they are always so much on the user's side.

QUESTION: How do I unpin the Firefox icon from the taskbar without uninstalling? I have an idea that there is a registry hack that will achieve this.

Hi my old PC crashed and I had to do a new windows install, but before that I saved all my old files, folders etc and presume Thunderbird email profiles on to it. I added the files back to the PC on same C drive once windows re-installed. Now how can I download Thunderbird and make it use the old Thunderbird email profiles on the PC at present please?

Hej Jeg følger fremgangsmåden i artiklen Moving Thunderbird Data to a New Computer, men har lidt (store) problemer. Først fungerede det slet ikke. Efter slet og ny installation på den nye maskine fik jeg mails og adressebog over, men kalender mangle bortset fra et enkelt fremtidigt møde. Efter forsøg på export og import (under Events og tasks) får jeg dannet en fin iCalendar (.ics) fil som jeg efterfølgende ikke kan importere fordi filen ikke indeholder importerbare el Jeg prøver så at gennemføre hele processen med Moving Thunderbird ... igen, og får som ventet spørgsmål om Overwrite existing ..., som jeg svarer ja til. Der overskrives data, men de nyests mails kommer ikke med og kalender mangler stadig. Adressebog stadig fin. Noget tyder på min Thunderbird klient kigger efter data et andet sted end processen tror. Når jeg kigger i Thunderbird Account settings peges der ned i ...Roaming/Thunderbird/Profiles/...., men nærmere kan jeg ikke komme det. Er der en måde jeg med sikkerhed kan slette al data i Thunderbird, og så prøve at gennemføre Move ... processen igen. Og hvis kalender stadig ikke kommer med over, hvordan får jeg så min dagbog tilbage fra 2009 over til den nye laptop ?? Venlig hilsen Johannes Elkjær Madsen

I am currently using IMAP. Rackspace hosts my email. I want to change ISP's. I understand that my Rackspace emails will disappear once I delete my Rackspace account and they will not be uploaded to the new ISP.

I need to have access to all my old emails and I don't care about the limitations of POP.

Before I make the move, can I switch from IMAP to POP and download all my emails? Will this retain the file structure - in particular, "inbox" and "sent"

If that works, I'll set up the new ISP for POP. Will new emails be appended to my exiting inbox and sent folders?

I am currently using Mozilla Thunderbird on my laptop. I am planning in using it as well on my Desktop. Is it possible to use the same email for both of my laptop and desktop?

Microsoft messed up the latest Firefox update. I had to re-install Firefox from the app store on Win11. I thought id would be a simple task of logging into my account. But all my setting appear to have been lost; home tabs, bookmarks, add-ons, etc. I have tried to sync from the settings menu and no different. The previous firefox install is still on the laptop but does not start.

Any ideas? I have searched everywhere I can think of and an hour later coming here. The bookmarks still appear on my phone at present.
