Thunderbird Portable 643h13

I have Thunderbird 45.2.0 Portable Apps version installed on a USB2 device that contains a SSD drive.

I run Kaspersky A-V on Windows 7, both fully updated. I have no plans to install Windows 10...ever.

When I load Thunderbird off the PortableApps Launcher or even by directly executing the "portable" wrapper exe, the program starts to consume memory...and eventually lots of it.

Having been a long standing fan of Portable apps and Portable Thunderbird, I now find that it is crashing all the time.
It is the latest version (sorry, can't fell you which one it is since it is freezing shortly on loading).
I it, the overall size of the application has increased to 4 GB since I move all the IMAP folders into a local Thunderbird folder that serves as my 'store' of emails on my SD card (leaving my IMAP email with more space).
I don't know what I am doing wrong.
Besides, am I right in reading that Mozilla have now discontinued to TB?

It is tempting to say it /never/ ends cleanly, but honestly it is more like 9 times out of 10.

I have an online Office365 email that I added to TBP using IMAP protocol. It has mostly been working fine. However, I've now run into an issue where email subfolders I've created through the online/web client do not appear within the TBP Subscribe dialogue. I've tried clicking the Refresh button on that window, but the subfolders still do not appear. Note that these are second level subfolders under the main (i.e. My_\Folder\Level_1_Subfolder\Level_2_Subfolder), if that has any bearing.

Thunderbird portable on a portable hard drive has been working fine for 2 months. Now it will not start up.

Thunderbird v45.1.1
Windows 10 Pro

Hi:

Recently Thunderbird v45.1.1 began showing the quick filter toolbar and the message preview pane on the first start after windows is started.

I would uncheck to show quick filter toolbar option and also uncheck to show message preview, then exited thunderbird. Without restarting windows 10, I would start thunderbird again and thunderbird would keep the settings for not showing the quick filter toolbar and message preview pane.

Lately, everytime TBP asks if I want to compact my my folders, and I click OK to start the process, it comes back a few moments later with the message "Some folder (e.g. 'Inbox') cannot be compacted because there is not enough disk space. Please delete some files and try again."

I have 29.1GB free on my USB drive. What more do I have to delete to allow the compact to succeed?

Hi,

I recently upgraded from Thunderbird 38 portable to Thunderbird 45.1.1 portable.

Now it is no longer automatically marking the message as read after they are open.

The settings at OPTIONS -> DISPLAY -> ADVANCED ->
"Automatically mark messages as read" is properly set.
I tried different settings, like "Immediately on display" and "After displaying for X seconds".

No X-out on my tabs..The "X" is light in color as though it's unavailable... I wiped folder and brought back up. Still NG. Anyone else experiencing this?

Hi folks,

aside to the portable version of Thunderbird I use a normal installed one. All my data are stored on a different hard disc than the system and program files. In prior installations I moved the whole AppData directory to the other disc and created a link like mklink /j AppData d:/AppData.
Since Windows 10 this is no longer recommended. Microsoft stated that Windows can't be updated when the AppData is moved and other s have had bad experience with this.
