Hi. I have Thunderbird running on two, different computers. The older computer has many emails I'd like to merge on to the newer computer with Thunderbird.

Does anyone know how to do this? All I've been able to find is a solution that overwrites the emails of one or the other profile folders. I'd like to merge.

Thanks.

I get the following error message while saving a send message: "Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors."

This is my local PC, so no network error here. So, it most be a file access errors. How do I fix or resolve this issue?

I'm running on Ubuntu version: 24.04.2 LTS

Thanks,

Hi I'm wondering what people think about emails providing links for donations. If the email address is spoofed and the link is malicious were in trouble. So, assuming the email I received today was from Mozilla (and not a spoofed email address, shouldn't Mozilla ask us to visit it's webpage to make a donation rather than email us a link? Regards

Hi all, I'm using TB 115.18.0 (64-bit) and I am currently working on finding a solution to automatically back-up my mails from two accounts on regular base. I want to back-up the ImapMail-folder from within the profile-folder; while looking into it I found not only the two folders for the current accounts, but also 3 more, for accounts I had in use a few month ago, when I started to use TB and fiddled with it. As I do not want to waste space with unnecessary Data, my question is: can I safely delete these obsolete folders and their associated .msf-files?

Thanks for any help/advice

Hello, when using a dropdown list that is connected to an external source (excel on the cloud), firefox on android does not offer us options. It works in other browsers. Ideal worked in Opera. Where is the problem with firefox?

Best regards Minárik

Hi Team,

I’ve successfully built Firefox v135 from source on our internal development RISC-V64 platform running on Ubuntu 22.04 with GNOME 42.9 (Xorg & Wayland), Our RISC-V Development platform does include a GPU HW which support HW Acceleration for GNOME & other 3rd Apps (Supporting X & Wayland), and Work seamlessly without any issues.

The FireFox v135 Application (via ./mach run) starts up normally. But the major issue I'm observing is that Firefox browser is very slow and laggy, especially during search operations and video playback on YouTube I see a poor performance. Upon further check I found that the most of the work is getting done over the CPU and the utilization is quite high, which is causing the FireFox to perform poorly. I also did try to switching to "Use hardware acceleration when available" in the Mozilla FireFox Settings, but still there is no difference with or without this check and Mozilla FireFox browsing Experience is very poor.

Kindly do let me know how we can enhance and improve the overall performance of FireFox Browsing Experience on my RISC-V platform. Any Support and Help is highly appreciative!

Attached a Build Steps and Configuration used for building Mozilla FireFox v135 on my RISC-V64 platform, let us know if there is anything missed. Thank you!

**BUILD STEPS**

1. Clone the Firefox source (v135.0.1):

git clone --branch FIREFOX_135_0_1_RELEASE --single-branch --depth 1 https://github.com/mozilla-firefox/firefox.git cd firefox

2. Install required dependencies:

sudo apt-get update sudo apt-get install -y curl python3-dev libnspr4 libgtk-3-dev llvm-14 llvm-dev clang libclang-dev libx11-xcb-dev libevent-dev libdbus-glib-1-dev m4 libnspr4-dev meson

3. Install Rust:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh source $HOME/.cargo/env

4. Install Python and Rust-related tools:

pip install --upgrade pip pip install uniffi-bindgen referencing==0.29.1 cargo install cbindgen

5. Apply the RISC-V compatibility patch:

patch -Np1 -i firefox-riscv64-hack.patch

6. Create the mozconfig file with custom build options:

ac_add_options --with-app-name=firefox ac_add_options --disable-release ac_add_options --enable-hardening ac_add_options --enable-rust-simd ac_add_options --enable-linker=bfd ac_add_options --disable-bootstrap ac_add_options --enable-official-branding ac_add_options --with-branding=browser/branding/official ac_add_options --enable-update-channel=release ac_add_options --with-unsigned-addon-scopes=app,system ac_add_options --allow-addon-sideload ac_add_options --enable-default-toolkit=cairo-gtk3-wayland ac_add_options --with-system-zlib ac_add_options --disable-strip ac_add_options --disable-install-strip ac_add_options --enable-system-ffi ac_add_options --with-system-libevent ac_add_options --with-system-nspr

1. ac_add_options --with-system-nss

ac_add_options --disable-updater ac_add_options --disable-tests ac_add_options --enable-alsa ac_add_options --without-wasm-sandboxed-libraries

7. Vendor Rust dependencies:

./mach vendor rust --ignore-modified

8. Upgrade Cairo from 1.16.0 to 1.18.4:

1. Extract and build Cairo 1.18.4

tar -xvf cairo-1.18.4.tar.xz cd cairo-1.18.4 mkdir build && cd build meson .. --prefix=/usr/local ninja sudo meson install

9. Build Firefox:

cd firefox ./mach build

Regards, Saiteja.

I've been using K-9 for years. I also have been using an app called Hours Tracker (http://hourstrackerapp.com) every day for . . . well, literally decades now. Every week I use K-9 to send my weekly time record to myself. Hours Tracker exports the time log to two files and then creates an email with the two files attached.

For some reason, about three weeks ago K-9 started attaching only one of the two files. If I back up in the process and select Outlook as the email app, it works as expected.

Let me know if I can provide more info.

Thanks!

Hello, I have a web application that can send a base64 data, it crashes in mswsock.dll when data is big than 3Mo. I don't face this issue on other browsers. Appreciate in advance your help.

Firefox is running on the front, while I am RDP doing something else, it suddenly prompt for requesting to send cert, I am curious what's it. I did not do anything.

suspend any 3rd party addon, but not sure the way to nail down the issue.

🔐 Client Certificate Request Prompt

The website 3gw.inet.co.th is requesting that you identify yourself using a client certificate. 📄 Details of the Selected Certificate

Sucessfully installed Firefox 139.0.3 armv7 nodpi on an Android 5.1 tablet device, but no matter what website I try to access (even Google), a plain black screen is always displayed. Homepage and Settings page works fine, even those history thumbnails are showing the website correctly. If I click on the address bar to type something, it then suddenly changes from black to the actual website for a blink of a second and then gets black again.

Is there a way to fix this? Firefox Focus, Beta and Nightly behaviors the same. I already tried to uninstall and clearing data/cache. It seems a bug with this specific tablet device I am using even though it shouldn't, since Android 5.1 is still supported, isn't?

I've been using Tbird for many years for multiple accounts, and I have the junk filter turned on so it's supposed to learn when I mark a message as junk. But I have noticed recently that even when I mark messages as junk, if more of the same come in, they don't get caught by the filter as they ought to be.

1. Is there a limit after which the filter no longer learns?
2. It's the same filter, no matter how many accounts, right?
3. If I UNmark a message accidentally marked as junk, does it reverse that pattern in the filter?
4. If I highlight a group of unmarked messages and mark them all junk, does it learn from them?

Hello, i am not sure if this is the right place for my Question:

I love to use Thunderbird but in some moments the handling is quite confusing oder buggy. I don't know if i may do think wrong.

I do get Mails from other people with other styling Formats (e.g. Calibri Font from Outlook) and i always use arial. If i copy a text from an mail with other format, put it in my mail with the command "Paste Text without format" it does not always work. E.g. is the visual in my Editor often in Arial but when i send the mail, then i see in my sended mails that the font switched back to calibri. I thought the "Paste Text without format" option will delet the format of the inserted Text and using the default mail format which i defined in my settings?

Its annoing cause i always produce Mails with different styles in it. I am using the latest ESR Version.
