Which add-ons for Firefox?

[Langjan]

My Firefox 3.6.17 running on Ubuntu 10.04 is not opening some sites properly, notably Twitter.

Will add-ons help and if so, which of the long list of add-ons should I try?

While I don't use Twitter, it is still just a website, so no add-ons should be needed to simply display the page.
So long as you have Flash installed you should be okay (not sure if Twitter uses Flash, but still...)
When you say it's not displaying properly, what do you mean? Are you comparing it to how it looks in a different browser? Or on a different OS?

The Twitter front page shows, but when I try to login or to navigate to another page, only the heading shows, no content. I tried Internet Explorer on Windows XP on my virtualbox, same result, then I installed Seamonkey, same result, which seems to indicate that the problem is not with the browsers. Also my browsers are working fine with other sites.

sounds like a java issue.

Have you installed

sudo apt-get install ubuntu-restricted-extras

?

As for Firefox add ons... Flash aid is a must

Problem solved, many thanks.

So, what was it that solved your problem, flash aid, restricted extras, or something else?

Don't know for sure, ran the command code as suggested and installed Flash.
