Thanks for testing and the feedback guys - I appreciate it

.
Anupam, like you, I also access Box from my FF browser. I don't use a desktop app or plugins for this.
I've tested further with FF
unsandboxed and with JDK
disabled, and was able to upload files to Box.
Testing the same with FF
sandboxed (i.e. running in Sandboxie 4.03)
and with JDK
disabled, FF crashes again.
Conclusion: Sandboxie is the culprit.
And yes Anupam, I keep JDK disabled. However, in the past, I found I had to enable it in order to upload files to Box
once FF was running sandboxed. Uploading
used to work in a
sandboxed FF only if JDK was enabled. Now, regardless of whether JDK is enabled or not, FF would crash once I try to upload to Box. And yes, JDK is up-to-date - version 7.0.50.255 10.5.1.255.
I'm going to report the crash on Sandboxie's forums and see what Tzuk has to say. I'll post any feedback to this thread.
As for Java, I uninstalled it more than 6 months ago. I don't miss it and I haven't encountered any sites or programs that need it.
Question here: Even though Java has been uninstalled, I still have
Sun and
Oracle folders in
C:\Users\<username>\AppData\LocalLow. Are these leftovers I can safely delete?
