Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

About a week ago I started getting these update error messages stating "Update available - Firefox couldn't update automatically. Download the new version". I've also tried clicking "Learn more" on the error message but it's a dead link. Going into the settings for updates I am set to auto update, but when I manually check for updates it says "Failed to check for updates".

The help article on this issue simply tells you to download and manually reinstall Firefox, but I'm having to do this nearly every day. I work in IT myself so I know a "bandaid" workaround when I see one. Is there a solution to this issue?

When I try to set up my inbox for my email within Remote Desktop, Thunderbird does find the correct settings, starts to log in and stops with a warning "User canceled primary password entry" and then hangs while Sending login information...

Below that warning, it says Password OK but nothing happens beyond there. Unless I stop it, it stays at the Sending login information... stage for 5-10 minutes before timing out.

What is causing this cancelling of primary password entry? (as in nothing I'm doing).

I have been getting the "new version available, download now nag for over 2 weeks, and I have the latest version. Still get this issue repeatedly every day. Starting to become an every hour nag to update and install latest version of Firefox. Refuse to use Microsoft Edge or Chrome, and will switch off Firefox too if not rectified.

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

Recently I have found that I cannot download statements from my bank account, also at the same time (2/3 months ago) I cannot access a Tesco website from Firefox. I can carry out these functions easily from Microsoft Edge, so why the sudden change ? Can anyone please help me to fix this in Firefox?

All of the files I try to download fail immediately. Even extensions will not download on firefox. I have uninstalled and reinstalled and checked the download location. Downloads work on other browsers such as Chrome fine but nothing will download on Firefox.

I have installed Thunderbird on a new (Windows 11) lap-top. When I get to "Account setup>>Set up existing email address", and enter my password, I get the response "Configuration found in Mozilla ISP database", but when I click "Done," there is a long hesitation on "Checking Password", and finally the message pops up "Unable to log in at server. Probably wrong configuration, username, or password." I know my username and password are correct. All configurations appear to match those on my old lap-top. Server is att.net.

I prefer Thunderbird for composing, reading, and replying to emails, and have a decade's worth filed and stored locally on an older lap-top, which I will want to import.

How do I migrate the old Thunderbird profile to the new Thunderbird? Background: Up until mid-Jan 2024 I was using Thunderbird on Windows 7. In mid-Jan I did a "clean" install of Windows and installed Thunderbird. Due to a corrupted Windows installation, I had to do another "clean" install of Windows 10 Pro. Today I installed Thunderbird version 115.9.0. Everything went well. However, I don't have access to my old - pre-mid Jan profile - which has e-mails and contacts I need to access. Here's my setup: Thunderbird installed in D:\Thunderbird New Thunderbird profile is in M:\Thunderbird Old Thunderbird profile is in M:\Thunderbird-OLD

How do I migrate/import the old messages, address book/contacts, and find out which extension I had installed?

Thanks.

I wish to try K-9 Mail on my Android - eventually I want Thunderbird. When I start K-9 it offers me "IMPORT SETTINGS" and then says CHOOSE FILE. What file(s) do I need to bring over from my Thunderbird profile to get 1. the address book(s) and 2. the email account data?

I have a friend who has been using the Outlook email client with her Gmail account. She's looking into moving to Thunderbird. Is it just a matter of... - making sure that IMAP is enabled in her Gmail account - installing Thunderbird - adding the Gmail account and credentials to Thunderbird

She's got lots of folders so is concerned that they won't be lost in the process.

I downloaded Firefox for my new Mac. I see a Firefox symbol on my desktop. Clicked and moved the thing to my applications.

Can't open Firefox because I have no Icon on the desktop or in the Dock. How do I get an Icon?

Since the latest Firefox update a few days ago, I am not able to log into my Outlook/Webmail account; nothing happens.

I can access it on google chrome but not on Firefox.
