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

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!

For the past week, my browser does not auto-update. I have to download the update and re-download the browser.

I went into the settings and found the update section and when I clicked "Check for Updates", it kept saying "failed to check for updates". I tried with my proxy-settings on with VPN on, proxy-settings on with VPN off, proxy-settings off with VPN on, proxy-settings on, with VPN off.

This is in my personal laptop, where I am the only and admin profile.

My Firefox used to to auto-update but now it keeps saying I need to download the update, but my browser can't even tell if I have the most current version or not.

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'm making this thread since the previous one was closed and provided no real solution, yet the result shows on the very top of Google. So I like to provide helpful information to others in my answer below.

I just needed to reset my kindle hd 10 to factory. When I try to sign in to firefox in order to sync bookmarks, the page won't open but only spins. I was able to sync bookmarks when I bought the kindle in December. Thanks.

Support page indicated e-mail migration from Outlook had to be in Version 31.8, then allow Thunderbird to automatically update to latest version. Successfully completed migration to version 31.8, however the About Thunderbird window states that "Thunderbird is up to date" and "You are currently on the release update channel." It does not automatically update to anything.

Alternatively tried changing profile pointing, also moving Local Folders mail to profile folder for updated version 91.4.1 also installed on computer without success.

Any way to convince 31.8 to update?

Hi, new updates on Version 98.0.1 quite a hassle for me. It auto-download all my files even when I just want to view. Is there any other way to disable this feature? I opened Setting>Download but there is no disable button or checkbox for that. Please help me. Thank you in advance.

I bought this laptop because it had Windows 10 so I could download firefox, The laptop immediately updated to Windows 11, no way to stop it. I am locked out of my microsoft account, have been for years. How do I get firefox downloaded ?

I have used Eudora for years, about 20 or more. Now I find myself with a dilemma. A secure email program I signed up for must have ports assigned to incoming and outgoing servers. Alas, not possible with Eudora, but possible with Thunderbird.

However, after reading several of the threads of migrating to Thunderbird from Eudora, it appears to be problematic--new addons, missing mailboxes, etc. It's hard to tell whether that's the norm or the exception. One of the threads I read was https://support.mozilla.org/en-US/questions/1228297 "Migrate Eudora mail to Thunderbird mail", which suggests starting with Thunderbird 17.0. That thread is from 3-1/2 years ago. Is this still the best way to migrate? Or is one of the Thunderbird migration tools a better and safer option.

I have literally thousands of saved emails and dozens of separate mailboxes and I don't want to lose them.

I don't have time and effort to describe the scenario as I am getting sleepy. But I have pics to describe what I have experienced. But having that experience, I felt started to hesitate downloading your installer of mozilla firefox but I nahhed it to continue installing until I successfully installed mozilla firefox.

I just concern.

Basically, a requested relaunch blanked my profile and I can't get it back.

I have a lengthy workaround that will take over an hour to fix from backups, before this incident, but I'd really like to understand what's going on. How can my add-ons, bookmarks, history, logins, etc. be gone? If I did a refresh on purpose, why would my shortcuts remain intact? And, I started by backing up my profile folder to a neutral spot, so why isn't replacing it reversing the changes?

As background: The "about:profiles/Restart With Add-ons disabled" button brings up a small button dialogue to choose "refresh" or default "open." I selected "open" because I didn't want to fix my profile and assumed I would relaunch with only add-ons disabled, so this was a potential point of screw-up. I assume selecting "refresh" would reset application defaults and make a mess exactly like I find myself in now. Shouldn't "Restart with Add-ons disabled/Open" relaunch a temporary and reversible state? Doesn't "refresh" prompt a new default profile?

Considering evidence only, it appears I did something to roast my profile before I backed it up, but that's strange and really out in the weeds, and I'm assuming I wrecked it with my current activity.

The default profile name and path are correct. My shortcut links and labels that I use for a home page are intact but with icons missing, the same appearance as if I deleted the cache; is this detail part of application settings and not profile?

When I try using the box to align fields (First Name, Last Name, etc.) I get a couple of lines to match up and then after that as I continue they all start to float around. What is the method for setting the left side with the right side of the box? I'm importing my address box from Gmail.

I am moving my email hosting from one hosting account to another. I have both accounts configured in Thunderbird. The original account has many many folders and sub-folders. How can I copy the structure and all the contained emails to the new account?

Hi,

I've recently upgraded to the 91 version and the order of the account folders have changed. i.e. the email folders and the off-line personal folders are no longer in their previous order. How would I change the order.

I tried moving them, but they return to their original position after every reboot of thunderbird 91.

Additionally, is there any good docs about folder paths to learn more about archiving or default settings.

Thanks,

I guess this could be considered "migration"... How can I sync the email between different machines, as & when I switch to use of a different installation of Thunderbird?

Here's my current setup: I have 2 laptops, and each is set up as a dual-boot with both Windows 10 Pro, and AntiX Linux. That makes a total of 4 operating systems, and I have Thunderbird installed on all 4.

I'm not sure how useful this is, for framing an answer to my question re. syncing, but here's extra info: I keep all my personal data on encrypted external hard drives, which I access using VeraCrypt. External is so I never lose my data if a given machine dies. Encrypted is so, even if the physical external hard drive is stolen, they can't steal the personal data. (I maintain a cloned backup external drive.) Today, I chose a location on the primary external hard drive, and created a folder named "Thunderbird email". I'm using the AntiX v19.4 OS right now, so I've set that new folder as the Local Folders location within this installation of Thunderbird.

I got this far, and then realized I need some guidance from more experienced users. So, I located this support page, and signed up for asking my questions about Thunderbird. Thanks in advance, for any help you can give me.

Hello,

I've set up Firefox to ask before updating, so I was taken aback by the fact that today, an update was automatically installed without Firefox asking me... (I was updated from 97.x to 98.0)

It is especially frustrating, as the mandatory "Restart" screen is broken when using several profiles, at least under Debian.

Let me know if you need more information.

Best regards,

Adonis
