Shouldnt they be displayed thru a text processer such as notepad?

I do agree that would be ideal. Unfortunately that is not how our system is setup. I have spoken with the developers and they claim its because they develop primarily for IE. However our IT policy explicitly exudes IE from our environment. Is there not a way to handle this issue by making changes in about:config?

so when you open a .txt file you are sent to Firefox?

have you tried using the control panel to change the defualt .txt to notepad

and in FIrefox, refer to the link below?

• Applications panel - Set how Firefox handles different types of files

No actual file is generated. When a user opens a report, a new Firefox window opens displaying only plain text (I'd attached a screenshot but it contains confidential data and my boss won't allow it). I think it is just plain text generated by php and then displayed as a webpage

I dont think such has changed in Fx22, let me check.

EDIT: nope, does this happen in other places in your workplace?

only with users who upgraded to v22 of Firefox

Did you inspect the page source to see if this is a text file or an HTML file with PRE tags?

• Firefox > Web Developer > Page Source
• Tools > Web Developer > Page Source (Ctrl+U)
• right-click on a web page to open the context menu and select View Page Source

With what content type does the server send the file (Tools > Page Info > General)?

It is an HTML file with PRE tags

Such an HTML file with PRE tags should be display as it is send.

Only PRE tags or other HTML code as well?

Can you post a short excerpt to check it out?

You can use <pre>PRE</pre> tags on this forum as well.
If there is other HTML code then the result might be unpredictable.
