If you have a list of URLs that you want to open in new tabs, it becomes a tedious task to copy and paste each URL into different tabs one by one.

Luckily, there is a Mozilla Firefox extension to take care of this job for you.

Multi-Link Paste and Go is a simple add-on designed for opening multiple links in a new tab from clipboard in one go.

How Does it Work?

• Separate URLs with new lines
• Copy the URLs to clipboard
• Paste the copied URLS to firefox with the shortcut CTRL+SHIFT+V

Multi-Link Paste and Go opens each valid URL in a new tab.

If you have invalid URLs, line breaks or any spaces in the list, Multi-Link Paste and Go just ignores those lines. The add-on supports up to a maximum of 50 URLs at once.

Another Helpful Firefox Plugin

If you’ve opened a page and want to browse all links on the page, here is another useful Firefox add-on for you. Multi Links helps you open multiple links at once.

I got a new notebook after my last laptop, HP Pavilion,  was gone due to some heating problems. While moving all data, I was not sure whether to continue with Thunderbird, since I heard that Mozilla stopped Thunderbird development.

There was a free built-in alternative mail software in Windows 8, but it was not supporting POP email.

So for the time being, I decided to continue with Thunderbird but needed to move Thunderbird profile to the new PC.

How do I move Thunderbird profile to a new computer?

Moving your profile data to a new PC is easy. I will outline the basic steps here, but you can find the official Mozilla documentation here, in case you need a more detailed guide.

Step by Step Migrating Your Thunderbird Data

1. Copying Your Profile Data From old computer
   • Close the Thunderbird
   • Go to the directory where your profile data exists
     • For Windows XP; “C:\Documents and Settings\{UserName}\Application Data\Thunderbird\Profiles\”
     • For Vista, Windows 7; C:\Users\{Username}\AppData\Roaming\Thuderbird\Profiles\
     • Copy the Profile Directory
2. Paste the Profile Directory to the new computer
   • Install Thunderbird
   • Open it once so it set up all the folders and data
   • Now Close Thunderbird
   • Go to the directory where your profile data exists
     • For Windows XP; “C:\Documents and Settings\{UserName}\Application Data\Thunderbird\Profiles\”
     • For Vista, Windows 7; “C:\Users\{Username}\AppData\Roaming\Thuderbird\Profiles\”
   • Delete the existing profile directory
   • Paste the Profile directory from the first step
3. Change your INI file to the new profile
   • Go to the directory where your profile INI file exists
     • For Windows XP; “C:\Documents and Settings\{UserName}\Application Data\Thunderbird\”
     • For Vista, Windows 7; “C:\Users\{Username}\AppData\Roaming\Thuderbird\”
   • Open “profiles.ini” in your favourite text editor
   • Find the  the “Path=Profiles/XXXXXXXX.default”
   • Change XXXXXXXX with your profile directory name from first step
4. Start Tunderbird

You should now see all your email accounts and emails as you would on your previous computer.

Migrating Thunderbird Profile – Visual Guide

Once more, you can find your Thunderbird Profile directory at the following locations

• For Windows XP; “C:\Documents and Settings\{UserName}\Application Data\Thunderbird\Profiles\”
• For Vista, Windows 7; “C:\Users\{Username}\AppData\Roaming\Thuderbird\Profiles\”

1 – Copying old profile

2 – Pasting the New Profile Directory

3 – Changing the Thunderbird INI file

You can find ini files at the following locations for different operating systems.

• For Windows XP; “C:\Documents and Settings\{UserName}\Application Data\Thunderbird\”
• For Vista, windows 7; “C:\Users\{Username}\AppData\Roaming\Thuderbird\”

 Check If Everything is Working

Although everything seemed to be migrated successfully, when I tried to send or get emails, Thunderbird was not able to receive or send any messages. Following error was popping up while sending any emails.

“Sending of message failed.
The message could not be sent using SMTP server smtp.mail.yahoo.com for an unknown reason. Please verify that your SMTP server settings are correct and try again, or contact your network administrator.”

After some searching, I found out that the problem was caused by Avast. The antivirus software, Avast, was not happy with this migration.
If you encounter a similar problem, first disable the avast and check if you can send or receive email.

If Avast is the cause of the problem, then you can solve this dilemma by re-importing the mail shield certificate back to Mozilla Thunderbird.

• Delete the current avast certificate from Thunderbird.
• Export the Avast mail shield certificate.
• And import the new mail certificate to Thunderbird.

Follow this link for a more detailed explanation on how to export and import the mail certificates.

If you got a new PC or laptop, you could easily move your Firefox profile data to your new computer. All you need is to copy and paste profile directory files to the new computer.

There are tools to backup and restore the profile data, or synchronize your profile among different devices but you can to do it manually if what you need is to permanently move your profile data to the new PC.

Where is My Firefox Profile Folder?

First, let’s find where your Firefox profile data is.

The location of Firefox profile folder in Windows XP or Windows 2000:

“C:\Documents and Settings\{username}\Application Data\Mozilla\Firefox\Profiles”

Or if you are using Windows Vista, Windows 7 or 8, you can find it here;

“C:\Users\{username}\AppData\Roaming\Mozilla\Firefox\Profiles”

Don’t forget to change the “username” with your windows username.

You will find a directory in the format of “XXXXXXXX.default”, which is your Firefox profile folder. XXXXXXXX is a random string of 8 characters.

If you can’t locate your profile folder, check out this link for a more detailed explanation.

Copy Your Profile Data

Now, copy the directory, “XXXXXXXX.default”, to a flash drive, dropbox, google drive or wherever you could access it from your new computer.

Paste Your Profile Data

Go to the directory where your firefox profile exists on your new PC.

Double click to browse your “XXXXXXXX.default” on your new PC. Delete all the contents of this directory.

Paste the contents of the profile directory from your previous PC to this directory

You should be able to see all the bookmarks, extensions, themes, passwords, preferences, cookies from your last machine on your new PC.

I read a couple days ago that search engines may fetch both www and non-www versions of a domain as separate domains if  redirection is done by using CNAME.  What this means is that you have exactly the same content on two different domains, www and non-www versions of the same domain. This might have negative effects on your rankings on google and other search engines.

So what is the solution? You need to redirect www to non-www or non-www to www version using the http 301 redirection in the htaccess file.

Here is the code for redirecting www to non-www.

RewriteCond %{HTTP_HOST} ^www\.(.+) [NC]
RewriteRule ^(.*) http://%1/$1 [R=301,NE,L]

or you can hardcode your URL if you prefer to.

RewriteCond %{HTTP_HOST} !^yourdomain\.com$ [NC]
RewriteRule ^(.*)$ http://yourdomain.com/$1 [R=301,L]

Redirecting from Non-WWW to WWW

If you want to redirect from non-www to www, you may try the following code in your htaccess file.

RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTP_HOST} ![0-9]{1,3}\.[0-9]{1,3}\.
RewriteRule !"" http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L,NC]

By the way, don’t forget to include the following directive in your htaccess before adding the above codes.

 RewriteEngine On
