from today I cannot download my gmail to Thunderbird, I'm getting always here below error code:

“400 invalid_request” or “Access blocked: App sent an invalid request,” it means the app uses an authorization method that Google doesn't allow. Google has safe ways for you to sign in and share your Google Account data with third-party apps and sites.

Please let me know how to proceed.

Thank you

My mail is hosted on Hostpresto. Yesterday 'someone' (it wasn't me. I was in bed) gained access to my cPanel and email and deleted my only email address, then installed their own. All my mail gone. I was stupid though - I opened another email address with the same name as the old one and started Thunderbird on the pc. Of course, it synchronised to the empty folders!

Luckily I have another instance of TB running on another machine and it's all there - I am not internet connected there!

How do I bring the folders containing all the old mail from the 'safe' machine's appdata/roaming/thunderbird location to what will be my 'working machine' without it immediately synching to the server and deleting it all?

Thanks Andy

I drag-n-dropped an account (POP3) folder "inbox" to the "Local Folders". How can I return the "inbox" folder back to my account folder ? Drag-n-droping back does not work.

I am running version 125.0.3 (64-bit) on Windows 11, and I can't check for updates and have to manually download each new version after given a popup telling me that the latest Firefox update couldn't be installed. I've tried restarting the computer, tried running the Mozilla Maintenance Service, and installing the latest updates for Firefox and Windows 11. Nothing I've tried has worked, and no other help article has helped me thus far.

According to Help>About Thubderbird the current version is 115. But searches in my browser tells me the latest version is 105.

Am I not searching deep enough?

Thanks, James

Since installing Ubuntu 23.10 on my new desktop pc, Thunderbird is failing to see the account details in .thunderbird I copied all the files from my backup into a new account directory (/home/cfi/.thunderbird/y4xyxmli.default), a technique that has worked many times in the past, but not this time. Previously, thunderbird has simply taken the settings from the backed up files and used those to connect to my organisation's mail server. Any ideas? How can I force Thunderbird to read the old account settings?

Many thanks.

My email provider required me to migrate to a new server and advised setting up a new Account in Thunderbird. I did this and it successfully imported most or all of my stored emails from the old server. However, the import only preserved the first level of sub-folders (I have up to 3 levels). If I right-click on my email account in Thunderbird and choose Subscribe, I can still see the sub-folder structure there. Is there any way I can restore it so that it (a) shows the full collection of sub- and sub-sub folders in the tree; and (b) locates the correct emails in each sub-folder? If not, I face days of work to recreate sub-folders and move emails to their correct location. Thanks for any help!

How do I move all my message filters and address books from my Windows desktop PC to my Windows laptop?

I have three email accounts and ten address books. (The message filters use the address books to sort messages into folders.)

There are a bunch of abook* files in the root directory of the profile. Is it sufficient to move these to the laptop, or are they indexed somewhere?

There are msgFilterRules.dat files in many subfolders of Mail and ImapMail. Is it sufficient to move all of these into the corresponding folders on the laptop?

Is there an easier way to do either of these?

Hi,

There many extensions such as:

https://addons.mozilla.org/en-US/firefox/addon/search-on-imdb-context-menu/ that say when trying to install:

Installation aborted because the add-on appears to be corrupt.

I am using Firefox Developper Edition, with extensions.langpacks.signatures.required set to false.

This addon, after download, installs fine as a temporary addon.

How can I install it permanently?

Thanks.

I am struggling with Gmail and Yahoo mail account in TB these few days. I hit almost the same errors from both. I generated app password for Yahoo mail, and put it in when setting up new account. For connection security: SSL/TLS For authentication method: tried with Normal password, Encrypted password, and OAuth2 However, I am seeing the expected authentication window pop up when trying the OAuth2. For all three authentication method: errors are always the same --- unable to connect to your IMAP server. I've followed another instruction to change maximum number of server connections to cache into 1 or 10. Error messages were the same imap one. So, what should I do/try for next?

I have two desktop icons for Firefox. Each opens to a different file. How do I clear the old file? What do I do about the message that Firefox can not update automatically? Where do I look to see Firefox file and see what date it is downloaded? If it is operational? Why is the same series of problems repeating daily?

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

After creating a IMAP email setup instead of the old pop3, I want to move my old folders over to the IMAP setup, but when clicking 'copy to', 'move to' or just simply dragging them nothing happens. No errors no nothing.

Whats wrong ?

Hello Ladies and Gentlemen!

Please read my post completely before answering! Thank you!

I'm using

• Firefox DevEd (manually installed) as my primary driver and
• the standard Firefox (installed from the package manager) for leisure/hobby related browsing

each with its own Mozilla account and profile, on Manjaro KDE. Sadly, either Firefox sees all the profiles. They have usually different versions. If I mistakenly start one of the Foxes in the other Fox's profile, the newer version of Firefox (usually Firefox DevEd) autostarts migrating that profile. Which it renders the profile "corrupted" for its intended Firefox.

I'd like to have Firefox DevEd unable to see profiles (or anything else) intended for the standard Firefox and vice versa. Or at least unable to botch profiles. I do not want to disable migration or use no. Given that Firefox configuration location is hard-coded, I'm not having high hopes for my wish.

I'm wondering if there is a way to keep two Firefox installations completely isolated, other than running them in containers.

Thank you for your time!

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.
