I can't able to open the *.log files from the firefox browser and i need to open the file inside the frame
If i open the log file from firefox browser it is not open and throws an error as
"The address wasn't understood Firefox doesn't know how to open this address, because one of the following protocols (e) isn't associated with any program or is not allowed in this context."
What type of log file? What is the file name? What is the file path or URI?
You can open a log file with a text or word editor.
Try to open the file in Firefox via "File > Open File" or by dragging the file in the Firefox window. You need to use the file protocol to open a file from the hard drive in Firefox. You get this error if you type the file name with e:\\xxx in the location bar.
If you use "File > Open File" then you can see what URL to use.
