Updated web browsers for Windows XP

Opera, which is Chromium-based, announced that the last version for XP will be Opera 36, but support will continue with security and crash fixes. This is probably the best choice if you want to migrate from Chrome with few hassles and no radical changes.

Yandex.Browser, based on Blink and Chromium, still supports XP and Vista and offers a look similar to Chrome.

Although Chrome is no longer supported on XP, Chromium is reportedly still working, with some instabilities with videos. It's a pretty good option if you are still used to the Google browser.

Pale Moon used to support Windows XP until version 27.0 Mypal is a currently maintained browser for Windows XP based on Pale Moon that continues the work abandoned by Moonchild Productions, offering the security and the customization of all the Firefox-based browsers.

Slimjet, another Chromium-based browser, announced in May 2016 it will remain compatible with XP and Vista. In fact Slimjet 10, based on Chromium 50, still continues to support these Windows versions.

Advanced Chrome is a special fork of Google Chrome: its Custom Build version offers an improved Download System, integrated Flash Player and support for NPAPI, JAVA and Silverlight that were removed from Chrome. The best part is that it's still compatible with Windows XP and updated (as of May 2018).

SeaMonkey is an Internet suite that consists of a web browser (inspired by Netscape), an e-mail and news client, an HTML editor and an IRC client. It is still compatible with Windows XP SP2+ and has very low requirement.

Midori is a lightweight web browser based on Webkit engine. The browser is not updated since August 2015, but it still works great on Windows XP.

K-Meleon is a lightweight and customizable web browser based on the Gecko engine used by Firefox. The program is available for Windows XP and higher.

IceDragon is a browser based on Firefox and customized by Comodo. The official website automatically offers for XP users the version 40.1.1.18, based on Firefox 40.0.2: it works great, but if you want to use it the first thing you have to do is blocking the automatic update by going in Settings/Advanced/Update/Never check for updates. If you don't block it, the program will search and download latest version of the browser, which is not compatible with Windows XP, and it will crash.

Lunascape is a web browser that handles 3 different rendering engines: Trident (Internet Explorer), Gecko (old Firefox) and Webkit (Safari). Unfortunately it can be used on Windows XP with the Webkit engine only: Gecko seems to be no longer downloadable and Internet Explorer engine is basically unusable.
