Kill Flash

July 14, 2015 Leave a comment

Problem
You may have heard that several vulnerabilities came out recently for Flash, thus Mozilla decided to deactivate the Flash plugin in Firefox.

How to remove Flash completely?

Solution

$ sudo dpkg --remove flashplugin-installer

Goodbye Flash, you won’t be missed!

No sound problem
In Firefox, playing HTML5 videos I had no sound. Here is how to fix it. Install the program “pavucontrol” and start it. On the Playback tab, HDMI was selected by default. Changing it to “Built-in Audio Analog Stereo” the sound came back.

list your Firefox add-ons

Problem
I use several machines and I would like to create a unified list that contains my favourite Firefox add-ons. This list could be kept in Dropbox, thus I could access it on all my machines. How to generate a list of installed add-ons?

Solution
The add-on Addon List Dumper can do exactly this. Here is a screenshot about this add-on:

bypass redirects in Firefox

Problem
There are certain sites where links are randomly redirected to other sites and if you want to visit the intended link, you need to click on the link three or four times and then maybe you are sent to the correct URL.

Solution
I found a Firefox add-on called Redirect Bypasser that allows you to visit the correct URL. On a link it shows a little icon, and the little icon is linked to the good URL.

Using several Firefox instances with different profiles

February 12, 2015 Leave a comment

If you want to use several Firefox instances with different profiles, read this post.

In short:

  • close Firefox
  • Start Firefox Profile Manager (firefox -P) and create a new profile. Give a specific name to the new profile, e.g. “NewProfile“.
  • Launch Firefox normally. It will start the default (old) profile.
  • Start another Firefox instance with the new profile: firefox -P NewProfile -no-remote
