Hello, We are running Roaming Profiles from our Active Directory architecture. It seems that a lot of files happen to have too long path&filename for example : \\Serverinfo\Username\AppData\Roaming\Mozilla\Firefox\Profiles\FirefoxUserProfile\storage\default\moz-extension+++f9efba58-d1ae-40d1-993c-f56654dc34c0^userContextId=4294967295\idb\{d1ae6e36-40f7-4f62-88b9... Do you have any idea to configure Mozilla so we keep it able to handle these filename length ? We cant use wildcard in exclusions so we cant exclude whats in a subfolder of each profile. It's not supported by ActiveDirectory GPO. Hope it was understandable please let me know if you need further details. Regards, Yannick GANTOU
