DOM Inspector missing from Firefox 2.0

Tim Huffam — Tue, 24 Oct 2006 23:46:00 GMT

If you've just installed Firefox 2.0 and found that the DOM Inspector is missing, here's how to add it:

Run the Firefox 2.0 install again.
Choose to do a Custom install (not the default of Standard)
Make sure DOM Inspector is selected.
Complete the install.

I had previously posted a solution for missing DOM Inspector for Firefox 1.x here. However that solution does not work with Firefox 2.0.

DOM Inspector not working in FF (FireFox)

Tim Huffam — Thu, 11 May 2006 07:40:00 GMT

When you install Firefox on windows, by default it does not install the DOM Inspector.

To make sure it installs it, select Custom Install then select Web Developer Tools.

If you already have FF installed you can install the DOM Inspector without having to reinstall FF:

Run the FF installer - just so it unpacks the install without installing anything.
Use file explorer to locate the C:\Documents and Settings\<username>\Local Settings\Temp dir. FF will have created a temp directory to unpacked the install components into (in my case "7zS17.tmp").
Start FF.
Drag adt.xpi onto the FF window. This installs the dom inspector.
Cancel the install.
Restart FF.

Thanks very much to clagnut for his informative post on this - and to Thierry B for his additional help on this.

Update for Firefox 2.0: (25 Oct 06)

Same problem exists - whereby it did not install the DOM Inspector by default. However the solution mentioned above does not appear to work (as I couldn't find the adt.xpi file) - so there is another work around - for which I've created another post (for feed subscribers).

Linux/unix commands cheatsheet

Tim Huffam — Thu, 24 Nov 2005 20:23:00 GMT

For those of you, like me with a memory like a seive.. here's a quick 101 on linux/unix commands:

Help/Manual (to get help on a command or shell):

man eg:

man cp

The following will show details of how to work within a shell, ie syntax for pipes, scripting etc

man sh

man bash

Once within man:

= scroll down 1 line

= scroll down 1 page

Q = quit.

Display contents of a file or output stream:

Once within man:

= scroll down 1 line

= scroll down 1 page

Q = quit.

List files in a dir:

ls (file/dir names only) eg:

ls *.txt

ls -l (full listing of file/dir details)

ls -l

ls -l *.txt

Redirect output stream (of a command) to a file:

> (overwrite) eg:

ls > files.txt

>> (append) eg:

ls >> files.txt

Pipe output string (of a command) to another command:

| eg:

ls | more

Change directory:

Show current directory:

pwd

Copy:

Move & Rename:

Delete/Remove file:

Delete/Remove directory:

rm -r

Filter data:

grep '' eg:

ls -l | grep 'myfile'

The search can be inverted with -v eg:

ls -l |grep -v 'myfile'

Count occurances of something:

grep -c eg?:

ls -l |grep -c 'myfile'

or by using wc eg:

ls -l | wc -l

Find a file containing:

find . |xargs grep -il 'text to search for'

Tar - to create a tar file:

tar -cvfz (Create,Verbose,File,gZip) eg

tar cvfz upgrade_datasynapse.tyar.gz datasynapse

z (gzip) is optional - if you want to compress/zip the tar

UnTar - to extract a tar file:

tar -xvfz (eXtract,Verbose,File,gZip) eg

tar xvfz upgrade_datasynapse.tyar.gz

z (gzip) is optional - if you want to uncompress/unzip the tar

List contents of aTar file:

tar -tvfz (lisT,Verbose,File,gZip) eg

tar tvfz upgrade_datasynapse.tyar.gz

z (gzip) is optional - if the tar file is compressed/zipped

Show processes:

ps -ef

Show process tree:

pstree -ahp

Show resource usage (cpu, memory, time, etc):

top

Note that top shows a line for each thread. To make it show processes only (one line per process) type Shift-H when top is running.

Edit a file:

if you're a masocist use:

or:

use a GUI (KDE/gnome) text editor

or:

Setup Samba (file system sharing) on your linux box and use a Windows editor

or:

Setup an ftp server on your linux box then use a cool windows editor called EditPlus (www.editplus.com) as it has FTP support built into it so it can Open/Save files to/from an FTP server.

Show disk usage:

df -k

Estimate disk usage:

du -k | sort -n

Print files:
