Web pages saved with Firefox can't be opened with Firefox


Web pages saved with Firefox can't be opened from my file manager (Thunar/VectorLinux) with Firefox. Why is this? I can open them with Opera and other browsers but not Firefox.

What file extension do these files have?

Does it help if you rename them and add a .html file extension?

There are other things that need your attention.

Your above posted system details show two outdated Flash plugin(s).
You should remove them both and update to the latest Flash 10.3 version.

  1. Shockwave Flash 10.1 r102
  2. Shockwave Flash 10.0 r12

Update the Flash plugin to the latest version.

Question owner

Almost all these files have a .html file extension.

What happens if you choose Firefox as the application to open those HTML files?

Did you check the file association settings for Firefox (usually firefox %u) ?

Question owner

When I open an HTM file with Firefox I receive this error message:

File not found Firefox can't find the file at /home/richard/News/Murray.

  • Check the file name for capitalization or other typing errors.
  • Check to see if the file was moved, renamed or deleted.

Try Again

Note: The path to the file is often abbreviated.

Where do I find the file association settings? In the Firefox menus Edit > Preferences > Applications there is no HTML file type listed.

Do these file names that do not work have spaces in the file name?

You can try to add quotes around the "%u" to see if that helps.

Question owner

Yes they often have spaces in the file name.

I do not understand what you mean by firefox %u or %u
