more firefox tips and tricks

One good thing about firefox settings aka firefox registry, is that you can edit them at your own will to suit your needs without having to dig down deeper from source code level.

Here are several firefox tips and tricks that makes your browsing faster, easier and more convenient, atleast to a larger number of firefox end users.

Make proper backups. To backup current firefox settings, you can issue

# updatedb
# locate prefs.js

and copy it to a different filename like prefs.js.old

If the below changes crashes your firefox, just copy your backup setting overwriting the other one then restart firefox. Do this at your own will, you've been warned. It worked with my box type, yours might be a different story.

However, if all things fail, just remove and re install firefox like so:

# yum -y remove firefox
# mv /root/.mozilla /root/.mozilla-old
# mv ~your-user-name/.mozilla ~your-user-name/.mozilla-old
# yum -y install firefox

without any consideration to previously installed firefox addons, plugins, cached sites or download history.

You can create a backup copy of these folders and copy it back after your firefox reinstallation just incase.
