ZIPs close instantly when "Open with Windows Explorer" is selected
If I download a ZIP file and tell Firefox to open the file in Explorer when it completes, the file will sometimes close by itself after a variable length of time (usually less than a second, sometimes as long as two or three). The problem does not occur if I select a different program e.g. 7zip, or if I save it to Downloads and open it manually. Navigating to /AppData/Local/temp/ reveals that the ZIP is still there and can be opened normally even after it seems to disappear.
Firefox Menu > Tools > Options
- Applications > Search for "ZIP" > Change the Action to "Always Ask"
It's already set to always ask.
Make sure that your anti-virus software isn't locking this ZIP file or is interfering otherwise in a way that Windows Explorer doesn't like.
Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
I just checked, the problem still occurs if my antivirus is disabled. I'll try safe mode tomorrow to see if it fixes the problem.
I've also been able to reproduce the issue in Seamonkey (which is much more up to date) so it doesn't seem to be a version-specific issue.
Please update, as using an old version of Firefox leaves you vulnerable to attack, plus it's known to be unstable and slow. Thank you!
