Only Firefox, Firefox Lite is retired. See End of support for Firefox Lite.

Hello all, I have a mobile with android version 5. Which one is better for me to download, Firefox Lite or Firefox general browser? Thanks

sometimes Firefox is too heavy on it and did not open sites, i download games from apkcurrent but it responds slow.

You may want to try Firefox Focus. It is a lighter weight browser, but does not have as many functions as Firefox for Android.
