Play Multiple Account with Script at the Same Time
I want to show to you how to make you can play more than one account at   the same time using and both are in firefox browser and both are script   on
Cookie and cache that are stored on the browser are the reason that you   cannot open more than one travian account at the same time. To encounter   this problem you can make 2 profile for your firefox so you can play 2   account with it at the same time
So now I will show you how to step by step on how to make multiple   account at for firefox. To make multiple account for firefox, you must   open the profile manager
Important: Before you can start the Profile Manager, Firefox must be COMPLETELY closed
Windows 7 and Vista 
Exit Firefox. To close Firefox, at the top of the Firefox window, select the File menu, and then select Exit
Open the Windows Start menu. In the Search box in the bottom left, type
firefox.exe -ProfileManager
Press Enter
Windows 2000 and XP 
Exit Firefox. To close Firefox, at the top of the Firefox window, select the File menu, and then select Exit
Open the Windows Start menu and click Run
In the Run dialog, enter the following
firefox.exe -ProfileManager 
Click OK
Note: If the Profile Manager window does not appear, you may need to   specify the full path of the Firefox program, enclosed in quotes; for   example:
"C:\Program Files\Mozilla Firefox\firefox.exe" -ProfileManager
If the Profile Manager window does not open, Firefox may have been   running in the background, even though it was not visible. Close all   instances of Firefox or restart the computer and then try again
So now you are ready to create new profile
Creating New Profile
To start the Create Profile Wizard, click Create Profile... in the Profile Manager
Click Next and enter the name of the profile.You can choose your account name in travian
You can also choose where to store the profile, which is useful if   you  plan on exporting your data and settings to another computer or   setup in  the future. To choose its storage location on your system,   click Choose Folder
Note: If you choose a custom location for the profile, store   it in a new or clean folder. When you choose to remove the profile, all   contents stored in the same folder are removed
To create the new profile, click Finish
So now what you have to do is go to where your firefox located at your browser>>right click>>properties
and this will appear
at the target it should look like this if you install the firefox browser by default
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe"
please note that I'm using 64bit windows so that i have the (x86) tag   there, for normal 32bit windows it should appear something like this
"C:\Program Files\Mozilla Firefox\firefox.exe"
Now what you have to do is changing your target by adding
-P yourprofilehere -no-remote 
right after your .exe
For example, my profile name is 'amroll' as example
the target link now should look like this
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -P amroll -no-remote
Now try clicking your icon, if you follow my steps correctly   you will see the browser directly without seeing the profile manager   windows
If you have completed all the steps above, you can repeat it   with all your firefox profile and rename it so you can know which is   which
