How to run multiple versions of Firexfox simultaneously
Posted by Bipul Raman on April 22, 2013.
Generally it is not possible to run two versions of Firefox. So we have an alternate method to make it possible. You may follow these following steps for this :
- Install any version of Firefox (Portable Edition) apart from the pre-installed Firefox.
- Close all instances of Firefox Portable.
- Copy FirefoxPortableOtherSourceFirefoxPortable.ini to FirefoxPortable (next to FirefoxPortable.exe)
- Open FirefoxPortableFirefoxPortable.ini in a text editor (even Notepad will do)
- Change "AllowMultipleInstances=false" to "AllowMultipleInstances=true" (no quotes)
- Save FirefoxPortable.ini
- Repeat for all other installations of Firefox Portable
- Run multiple installations of Firefox Portable .
