1437903 - Firefox does not close local file handles

Status: RESOLVED INCOMPLETE

(Core :: Networking: File, defect, P3)

Description

[Harry Fox]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36

Steps to reproduce:

Open a local web page in Firefox, then attempt to edit the local file. Even after closing the tab Firefox will maintain an open file session, meaning you can't edit the file until Firefox is completely closed.


Actual results:

In my specific circumstance, I compiled some JavaDocs, opened in Firefox. Attempted to recompile the JavaDocs, but was unable to delete the file. Even after closing the tab I received the same error.


Expected results:

Upon closing the tab, the local file session should be closed.

Honza, this is Windows only bug because AFAIK the files are not locked on other platforms. Can you have a look at it when you have a time?

I'll ask for the usual:
- can you be more specific which file you are opening and which file exactly can't be deleted/modified?  more details the better
- have you confirmed it's Firefox that keeps the handle open?  (you can use Process Explorer [1] and its Find/Find Handle or DLL function - Ctrl-F)
- can you reproduce with a fresh (new) profile?
- how does this behave in Firefox Nightly?
