Hi all,
My Thunderbird Calendar no longer want to sync with my online google calendar. For now I have used the Google Calendar plugin but I would prefer to get the original one working.
The location of the calendar is googleapi://email_address/?calendar=email_address/name
I'm assuming this is still acceptable?
Hello,
I have a few questions about my "Thunderbird Portable":
*
I have for my wife and me respectively copies on a Fritz!Box connected hard disk (NAS).
Since a Thunderbird update from 14.x.x to 45.4, the start takes up to 10 minutes and often crashes.
In addition, the address book is no longer visible in the view.
Hey,
I have some serious issues with FF, TB and several other Apps over PortableApps!
I own three different PC (Windows 10 64bit as User/AntiVirGear-N10, Windows 7 64bit as AntiVirGaming/AntiVirGamingT7 and Windows 7 64bit as User/AntiVirGear-N7) and all my data and apps are on a 1TB HDD without any errors (weekly SMART check, file defragmentation and chkdsk) and here is the point: It happens randomly!
Let me show you some scenarios and define N10 as A, T7 as B and N7 as C!
I configured an IMAP hotmail account in Thunderbird portable 45.3 as a backup.
I downloaded all emails and then I deleted the stored password (Options --> Security). Every time I open Thunderbird portable, it shows all email and tries to connect, but I don't enter the pasword to avoid synchronization. So this is working OK.
In Thunderbird I can drag and drop multiple jpgs into an email. in the portable version (beta version downloaded downloaded 4-22-17).
I cannot drag even a single jpg into my email. Is there a possibility that this will be in a future version?

Hi and thanks for reading this.
My wife and I have both used TB for years - mine as Portable TB on an external drive and hers as regular TB on her C drive. With her SSD getting full-ish, I decided to move her over to Portable TB on an external drive, but I've hit a problem.
I installed Portable TB on the drive and it ran fine, so I copied her original profile to the external drive, and again, no problem. TB fired up and I could see her existing email, and downloaded 20-odd new messages.
After an update through PortableApps launcher it crashes upon launch. Crash report: https://crash-stats.mozilla.com/report/index/6a9accf9-43a2-4e8b-9637-385...
Hello,
I'm surprised this article includes no information on how to migrate from Portable Thunderbird to the regular version, although there must be enough users out there who would like to do just this after trying it out safely through the Portable version.
