I've downloaded the new version, and extracted the tar archive. However, the installation instructions on the site were sparse, to say the least:

Quote:
Linux/GTK2

Extract the tarball in the directory where you want to install Firefox:

tar -xzvf firefox-1.5.0.1.tar.gz

This will create a firefox subdirectory of that directory
Doing just this, the firefox command still opens the old version, and the new version will open only if I specify the full path.

Entering which firefox points to /usr/bin/firefox, which is a symlink to the old firefox file. Should I just change this to point to the new version, or is there something more clever that I should do?

I had this same problem when I was trying to update from 1.0.7. I ended up waiting for debian to get a 1.5.0 version. Anyone know about the status of that?

IIRC, the tarball comes with an installer, so you'd have to execute the installer, instead of just untarring and running... try it as a non-root user first until you're sure you have it right... and yes, you'd have to specify the full path to the firefox binary until you replace your old one or adjust the symlink...

BTW, i recommend that you use a binary package from your distro instead...

i seriously doubt the stable branch will be getting 1.5 as it would go against the stability philosophy, but you can get 1.5 from the unstable branch: http://packages.debian.org/unstable/web/mozilla-firefox

yeah, I'm running testing, and I got 1.5 from unstable. I looked, and it looks like unstable's got 1.5.0.1(if that's the right version), so I'll upgrade from there.

I couldn't find an installer. There were a couple of other likely-looking files in the directory, but I couldn't get either to run (and like I said, the mozilla website was being less than helpful). In the end, I moved the folder to /opt (alongside the old installation), and recreated the link.

I then found that, although my bookmarks and cookies had been copied over, my plugins were missing. In the end, after searching for a way of setting these in the browser (and getting nowhere), I simply copied the plugins from the folder in /usr/lib /browser-plugins over to firefox's /plugins sub-folder and it worked. I can't believe it was that easy!!.

Thanks,
Rob

Secunia's put out an advisory already (and it's a big one):

there's been a non-critical security issue found in 1.5.0.2... even though the issue is non-critical, i figured it's in the thread's best interest to have it posted... here it is:
Quote:
Description:
PSPFrenzy has discovered a weakness in Firefox, which can be exploited by malicious people to bypass certain security restrictions.

Internet web sites are normally not allowed to link to local resources. It is, however, possible by a malicious web site to open local content in the browser by tricking a user into right-clicking and choosing "View Image" on a broken image, which is referencing a local resource (e.g. via the file: URI handler).

NOTE: This does not pose any direct security impact by itself, but may be exploited in combination with other vulnerabilities.

The weakness has been confirmed in version 1.5.0.2. Other versions may also be affected.

Solution:
Do not use the "View Image" functionality on untrusted web sites.

Firefox Exception Handling Full Path Disclosure Weakness (Not Critical)

Quote:
Description:
A weakness has been discovered in Firefox, which can be exploited by malicious people to disclose system information.

The weakness is caused due to file path information being included in certain exceptions being thrown by the browser. This can e.g. be exploited to disclose the full installation path by calling the "window.sidebar.addSearchEngine()" JavaScript function with invalid parameters.

This may reportedly also be exploited to disclose the full path to the user's profile via errors thrown in installed extensions.

The weakness has been confirmed in version 1.5.0.3. Other versions may also be affected.

Solution:
Disable JavaScript support.

The NoScript extension "should" take care of the JS vulnerability, unless it is a trusted site.
