Installing and Updating Portable Firefox Nightly

This is easy. You can do it in only a few steps.

Portable Applications (or PA for short) already has portable Firefox and portable Firefox Beta. A few other websites also create their own packages, including Nightly builds, to be installed in your portable app folder. But, PA does not support Firefox Nightly build. So you have to do it yourself.

There is a page on the PA forums that tells you what to do in order to install your own portable Firefox Nightly build. and here is what it says:

  1. Go to and download the latest trunk in zip version
  2. Use 7-Zip Portable to extract the contents of the zip file
  3. Copy the contents from the folder firefox to [Firefox Portable Install Folder]\App\firefox

Just remember that doesn’t support nightly builds, and there’s no guarantee that it won’t let any traces behind after you close it. read more...

StupidFile! – Cannot Delete File On Desktop

Written by Eric Bright

Updated on January 30, 2018

Objective: removing an apparently irremovable file or folder.

Affected OS: Windows 2000, XP, Vista, 7, and newer versions


You have a FOLDER on your desktop with a FILE in it, which you cannot delete.

You’re given this message:

“Cannot read from the source file or disk.”

Possible “solutions” that might not work:

  • You downloaded Process Explorer and examined every single process running in memory to find a sign of a program that may be using _something_ in that folder. You closed all programs, every resident applications, and all running processes that can be closed. You also closed even some of Windows process and stopped as many services as possible; no sign of any file handle to anything related to that folder… result: negative.
  • You have uninstalled many programs that you suspect they may cause the problem;… negative.
  • You tried to do “Open with…” then created a file with the same name, saved over the existing one… with no luck.
  • You have no Spyware, no virus and nothing suspicious at all.
  • You did chkdsk c: /f, RegSeeker, NortonDiskDoctor, Regedit (see also this), and lots of command line instructions that you read in forums;… negative (in regedit, you cannot even see any entry with the same name as that stupid file in your Windows registry.) (more about chkdsk.)
  • In the end, before installing a fresh damn Windows, why don’t you try this one:

Last resort:

At a cmd prompt type the following:

RD /S /Q [drive:] path


[on Windows XP]

C:\Documents and Settings[your log-in name]\Desktop\>RD /S /Q foldername
