list your Firefox add-ons

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?

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

bypass redirects in Firefox

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.

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

Firefox is started automatically but it looks corrupted

September 28, 2014 Leave a comment

On my home desktop I have autologin enabled, i.e. I don’t need to log in manually. Since I always need a terminal and a browser, “konsole” and “firefox” are started automatically. So I just switch on my machine and when I come back 5 minutes later, I’m ready to work.

However, sometimes Firefox doesn’t start normally. It looks strange: some colors are replaced with a different one, fonts are different, tooltips on tabs are plain black (text in tooltips is not visible), etc. If I restart Firefox, it becomes OK. I’m not sure what causes this problem, but my guess is that Firefox is started too quickly. I think it would require some libraries that are not yet loaded when Firefox is started. Then these pieces of software are loaded, that’s why Firefox gets OK after a restart.

The solution is simple. Don’t start Firefox immediately after the login. Wait some time until everything else is loaded, and start it after. Of course, we still want to start Firefox automatically, not manually. So we need a simple script:

#!/usr/bin/env bash

# /home/jabba/bin/
sleep 60    # Wait 60 seconds. You can play with this value.
/usr/bin/firefox &

Then in the Startup Applications, remove “firefox” and add this script instead. Provide the absolute path of the script. Make sure it’s executable. Here is a screenshot of the applications that are started automatically on my machine:
