As noted in my question something odd has appeared in my Thunderbird Email. Can someone help me get back to all English. I double checked my TB settings and it appears they are all set correctly.

Thanks, Brad

Hi there I tried many solutions that I found concerning body text not displayed. But hat no success. Let me describe in detail. From one day to the other the following happened. 1. Emails in the local folder stored on a NAS (for archive purposes) did no longer display the body text (from one day to the next) However I could still transfer them into the corresponding inbox and then read them. 2. Upon trying to change settings, reinstalling the newest version of Thunderbird and also an older version, the solution of putting the emails into the inbox and reading them or forwarding them to another account does no longer work What I tried:

      1. Repair the Folder:
      2. Rebuild the Global Database:
      3. Check for Add-on Conflicts:
      4. Verify Account Settings:
      5. Examine Local Folders Storage:

Now my knowledge is depleted and I am looking for help. Thanks in advance. nelexc

Since upgrade to 128.10.1esr, list of emails in local folders is visible, but cannot view email contents, cannot forward, cannot reply, cannot move, cannot delete.

IMAP folder functionality is all OK.

Occurs in both 64 bit and 32 bit versions of 128.10.1esr

After this occurred on 64 bit machine, we had 32 bit two machines running a previous version of Thunderbird that were still able to access (read, forward, delete, etc) emails in the same local folders (local folders are on network and accessible to 3 different computers).

After upgrading one of them, access to emails on local folders broke on that one, but still working on remaining machine running older version.

This means it is not corruption of local folders (e.g. folder repair and .msf deletion don't make any difference).

It seems to be a problem with this version since update.

How can this be fixed, do we need to wait for another update?

Hello, FF 139.0.4 on MAC Sequoia15.5. Lost ALL references to bookmarks, i.e. Bookmarks Toolbar totally gone. How can/do I restore from .jsonlz4 file in bookmarkbackups. Also, will I be able to salvage my previous profile, presumably containing my older "Tabs on Bottom" work-around? Alternatively, is there a process to restore JUST Firefox from Time Machine? Appreciate any advice.

Hi,

I'm on a fresh Windows and the CPU usage is waaaaay too big. When TB is out of focus, it uses about 10% of my CPU. This can go up to 15% when the window is active. It's not doing anything, not downloading or compacting or anything.

Thanks !

This problem just began today on my Win 11 laptop. Firefox is current - 139.0.4. Win 11 is current. No new software has been installed. Firefox hangs up and will not move. Task manager shows FF is consuming more than 90% of my 16GB memory. I must end the FF task to get up and running again.

Why does Firefox mobile for iOS look different on my iPhone 13 pro max vs my wife's iPhone 12 pro max? both UTD on iOS version. I suspect that I must be missing something in settings, but cannot figure this out. See images below.

On my iPhone 13 Pro Max, the Firefox app has the nice home button, tab button, and hamburger menu button on the bottom (address bar on top both cases). On my wife's iPhone 12 Pro Max, it has the "+" for new tab, the 3 dots instead of hamburger menu, and then the tab button. I much prefer the layout on my phone, as does my wife, but I cannot figure out how to change her layout to match mine.

Any help would be much appreciated!

I've moved thunderbird between windows 10 computers several times without any issues in the past, but I'm having problems now.

My old PC is running windows 10 with the most up to date TB. New machine has windows 11.

In the past, it was just a case of installing TB on the new machine and replacing the profile folder there with the one from the old machine.

Now when I do this I get "your thunderbird profile could not be loaded. It may be missing or inaccessible"

Ay help with this woould be much appreciated

Thanx for initial reply to my help request ...

My problem with Thunderbird downloading my Yahoo.com e-mails continue.

I've changed Yahoo.com passwords in the past with no problems. Thunderbird seems to have changed & become more complicated. I can't find the app password Generator for Thunderbird, but I'm able to see my Yahoo Password & the Oauth2 security protocol etc

So how in the heck can I get Thunderbird to work properly? And download my my messages into TB as it has done for years.

Hello, I tried following the steps on [https://support.mozilla.org/en-US/kb/.../moving-thunderbird-data-to-a-new-computer]. However, I currently have a flatpak installation where I land in a folder which also has executable among other files (?). I do not see the usually named profile folder and therefore cannot copy it to my new computer. Do you know how I can move in this case? Thanks

I just got a new Epson 3-in-one printer and tried to sign up for the warranty. I got a message that the warranty was expired... I went to the Epson support site on Firefox and Malwarebytes blocked the site as malware... It said I could add the site as approved, but I don't know how to do that. "https://www.epsoncom.com/my-account/home". The Epson site said I already had an account but my password was incorrect. I had an Epson printer more than ten years ago; I don't remember the password and they don't provide an option to reset it. HELP, PLEASE.

Google suggestion in Firefox's address bar keep showing Japanese suggestions even though I chose English and Canada as language and location with my google account.

I use same google account with google chrome, but google chrome doesn't show Japanese suggestion.

As for setting on Firefox, I unticked other than "show search suggestions".

How do I resolve it?

Thank you.

I've installed Thunderbird on my Pixel 9 Pro. I used my Linux Fedora Thunderbird to generate a QR code to get my Android Thunderbird established. Android Thunderbird is working ok but my contacts from the Linux Thunderbird did not come over and writing emails from there is difficult without my contacts. How do I port over the Linux Fedora Thunderbird contacts to my Android Thunderbird?

I've just installed Firefox for Android (v.66.0.5) from Google Play Store onto my Samsung Galaxy S10e (running Android 9). Installed OK and browser works fine, but results will not scroll vertically or horizontally. No similar problem with other apps. Is there a bug or am I missing something ?

Hello,

I'm a bit out of ideas how I can get Firefox to display the correct characters. For reference: https://learnjapanese.moe/font/

Windows: I only have german and japanese locale installed, i even changed in intl.cpl the language to japanese. I have installed the japanese language pack / fonts and it's showing correctly in any windows editor.

Firefox: Second language set to japanese, disabled all addons, tried it on private mode to no success.

Any ideas how I get the characters to display?

Edit: I made it work by changing in about:config the font.cjk_pref_fallback_order-string to have ja as first.

I have read your explanation on how to move TB to another PC. BUT this explanation assumes there is an App Data folder on the new PC. In Windows 11, there is no App Data folder and there appears to be no Profiles folder.

I had a tech guy move TB to the new PC, and I can now get and receive emails there. He could also copy over my Sent and Address folders, but NOT my older emails or, more importantly, my Calendar. How do I get TB to run on a Windows 11 PC like it does on my old Windows 10?

Thank you. Jim Bachman

I'd like to ask about Firefox's behavior and settings. I'm using Firefox with vertical tabs (using an add-on), but it seems to be behaving strangely. The things that have changed since before are: 1. Open from pinned tab 2. Now opens in a new tab → Previously it opened in the same tab 3. Clicking on a newly opened tab opens a new tab again → Previously it would open pinned tabs/same tabs → in a new tab It has changed. I haven't changed any of my Firefox settings. Windows 11 Home 23H2 Firefox version 139.0.4 (64-bit).
