AVIM – the Advanced Vietnamese Input Method – is the most convenient tool for typing Vietnamese on the Web. It’s available as a free extension for Firefox and related applications. With AVIM, typing Vietnamese is so natural you don’t even think about it.
Important: Firefox 57 and above is incompatible with AVIM due to the new WebExtensions feature that is replacing traditional extensions. AVIM cannot be updated to work in Firefox 57 until AVIM’s most basic functionality is possible in WebExtensions.

Still stuck using Chrome, Cốc Cốc, or Opera? Install AVIM for Chrome by Nguyễn Kim Kha. Webmasters can integrate Hiếu Đặng’s avim.js into their websites. Please note that, due to technical limitations, these “lite” input method editors cannot be as user-friendly as AVIM for Firefox.
