Thunderbird Portable

I get this error when trying to install the lightning (Calendar) add-on.

Script: resource:///modules/XPIProvider.jsm:1043

I noticed that a lot of plugins are installed on my ThunderbirdPortable. Since the client is very, very slow, I wonder if this could depend on this (also on the fact that my USB drive is quite old).

What's your opinion?

For the list of plugin please see this image.

Thank you!

Typically I want to open more than one program. At present the menu closes to the task bar and I have to click the running apps bottom right again (what used to be the system tray.
It would be more helpful if there was an option whereby the menu stayed open until the mouse is no longer over the menu area.
I think maybe that is how it used to work.

Ouch, horrible.
I got an email containing Exploit:HTML/IframeRef.gen.
MSSE deleted it but this involved deleting the entire single file
Local Folders\Inbox
containing many other healthy communications.
Luckily, but purely incidentally, I had backed up Inbox two days preciously, but still lost 48H of email.

Thunderbird keeps prompting to upgrade to 11.0.1 but it is not on Portable Apps so the upgrade will be the installed version.

Usually Portable Apps upgrades are immediate or just a day or so behind but this one is about a week or more ago.

Does anyone know why there is a delay this time please?

hello everybody.

i've got a problem. there was an automatic update with thunderbird protable. the version 11.0 was installed. but then there was no thunderbird10x-profile. so all my emails since february are away. can anybody help me, to find where my emails are??

thank you.

I have just updated to version 11.0 for both Portable Thunderbird & Firefox. AVG is no longer compatible, is this likely to change or is there an alternative that gives real time protection when using these products.
Thanks

Ich habe Thunderbird Portable seit Dez. 2011 auf meiner portablen Festplatte (via USB) installiert, um es auf 2 Rechnern - Windows XP bzw. Windows7 zu benutzen.

I've routinely used the portable version of Thunderbird from [link to illegal software site removed by mod JTH] - but the latest release is a puzzle I cannot solve. It runs once; the next time I run it, I receive a message that the application is in use. I've checked all the files and it seems that maybe there has been a change in the portable.exe file. Any tips will be appreciated. thanks,

I am somehow not able to find to day the setting where the tabs on TB 11.0 are shown bellow the icons etc.

In Firefox it can be switched, in TB ?

Can someone guide me to the setting?
