Hello,

For some testing purpose , I want to downgrade my PC's Firefox from 25 to 22.
How can I do that?

OS: Ubuntu

Is it simply like uninstall firefox 25 and install 22?

Please give me refer link of download Firefox 22.

is there command in Ubuntu to dowmload Firefox 22 directly,(which I may have missed)?

Hi, here you can find all the versions:

• https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/

You can use multiple versions in the same box, just run the executable that you want to use. However you may want to setup different profiles for each Firefox instance.
