Has anyone of you having a problem opening firefox , google chrome and thunderbird since yesterday? coz almost all of our unit that is running in ubuntu and Zorin OS are experiencing the same bugs.. i already tried updating and upgrading the OS but still having the error and i also tried re installing the applications but im not getting any progress..

No problem with firefox in kubuntu.

Foud the problem. it seems that the on access scanning of sophos is the one causing of the bugs.
