Firefox v3.6.2 is out. Official Slackware packages will probably be out
soon, but I just built it for myself and the process is trivially easy to
do on your own. The slackbuild from -current can now be used without
modification or fixups.

Steps:
1. Download the slackbuild source files (use a slackware mirror).
For example, get files from this directory:
<mirror>://slackware/slackware-current/source/xap/mozilla-firefox/

2. Delete* the following old files (or just skip downloading) from the
download directory:
firefox-3.6.tar.bz2
firefox-3.6.tar.bz2.asc

3. Download and verify signatures for the latest firefox 3.6.x from
Mozilla. Version 3.6.2 is available now. I retrieved these:
<mirror>://mozilla.org/firefox/releases/3.6.2/linux-i686/en-US/firefox-3.6.2.tar.bz2
<mirror>://mozilla.org/firefox/releases/3.6.2/linux-i686/en-US/firefox-3.6.2.tar.bz2.asc

Also: this is the md5sum,
68f7009935d2d88cd9cbd497416ddbbc ./linux-i686/en-US/firefox-3.6.2.tar.bz2

4. Run slackbuild to create package.
5. Upgrade your firefox using the new package that was just built.

It worked for me to use with Slackware 13.0. YMMV

Here is a capture of the "about" dialog:

* The slackware build script now checks the directory to find which
subversion of the 3.6.x series is to be built. Hence, no hardcoded
modification is necessary in the script itself. Just remember to delete
the previous version.
