[Dragtotab] dragtotab broken?

[Frederic Pont]

Hello,

I just installed dragtotab with Firefox 1.0 in Linux. I get this 
error:
*** loading the extensions datasource
*** nsExtensionManager::_finishOperations - failure, catching 
exception so finalize window can close [Exception... "Component 
returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) 
[nsIZipReader.open]"  nsresult: "0x80520012 
(NS_ERROR_FILE_NOT_FOUND)"  location: "JS frame :: 
file:///usr/local/firefox/components/nsExtensionManager.js :: 
nsExtensionInstaller__installExtensionFiles :: line 979"  data: no]

and the extention is said to be uninstalled after I restart Firefox, 
but it is not and the error reappears.

Thanks for your help
Fred
