I guess it is

This is a well known problem with xulrunner and eclipse 3.7.

Here's a workaround.

Thanks for reply. It seems like the provided #anker in the link is missing on this page. Am i wrong?

[paulvi]

Yes, it is actually is. I am not using Eclipse on Linux so I don''t follow. I just know that it was Lunix+Eclipse problem as mentioned in #1

Check also in related and similar plugin https://github.com/satyagraha/gfm_viewer/#usage

The plugin uses Eclipse's default browser, e.g. Internet Explorer on Windows; if you use Ubuntu or other Linux distros, we recommend the WebKit browser; see:

• http://www.eclipse.org/swt/faq.php#browserlinuxrcp
• http://www.eclipse.org/swt/faq.php#browserlinux

Please share what worked for you.

[paulvi]

[nadar]

i could not find a solution yet.

Maybe the file is too large. I guess.
