Uninstalling Printer in Firefox

Hello,
Does anyone know the trick to uninstall HP Smart Web Printing which is located in the Firefox extension. Because right now this one is compatible with version 3.5 of FF it works fine on IE8. In the extensions of FF uninstall button is unavailable (dimmed), is there any way around it. Thank you.

I have a solution for this

- Closed Firefox in Programs (Windows 7)
- HP / Digital Imaging / smart web printing
- I delete MozillaAddOn3 of a sudden I have no extension in Firefox.
- CCleaner a shot (for now useless registry keys) and it rolls.

It's still stupid that there have not been updated for FF 3, because this extension (when it was compatible) is handy. The question is whether it does damage the operation of the printer.

Removing MozillaAddOn3 does not solve everything, in fact it should simply delete the tool altogether HP Smart Web Printing , and thus we lose this functionality even under IE8 on which it works. For my part I do not like IE8 is not serious in itself.

The problem is as follows, after installing a printer Samsung SPP-2040B Photo size (10x15 cm), all printing in Firefox took into account even when a 10x15 cm A4 printer was used. The impression is also completely distorted when it is sent to the printer (a Canon MP130). Any help will be great. Thank you .

In my particular case, I noticed that for other users, printing working properly. So it must go into Documents and Settings / User / Application Data / Mozilla /Firefox/ Rep specific and edit the prefs.js file in Notepad as follows:

Replace:

Code:

---

user_pref ("print.your_printer_name. print_paper_data ", 120);
user_pref (" print.your_printer_name. print_paper_height "," 11.00 ")
user_pref (" print.your_printer_name. print_paper_size ", 3276853);
user_pref (" print.your_printer_name. print_paper_size_type ", 0);
user_pref (" print.your_printer_name. print_paper_size_unit ", 0);
