At this point in time, your best bet compatibility-wise is probably the New Moon project by Roytam1, which he forked from Feodor2’s “MyPal”. No XP-capable and currently maintained browser will be able to handle every modern web site out there. Hm, depends on what you mean by “works with XP Pro”. Or, just open multiple tabs, load web sites in them (yes, you have to) and watch Firefox spawn additional processes in Task Manager: Depending on how many browsers you have launched, it should show something like 1/1 (Enabled by user) or 2/2 (Enabled by user). To test this, open about:support and look for Multiprocess Windows. So tune that value to something your machine can take! If you spawn to many processes on a machine with just 2GB or 4GB of memory, you might run into swapping rather quickly!Īlso, you need to test this with your plugins and extensions! Not every plugin / extension will play nicely with e10s! In some cases the browser may even crash completely, or have individual tabs crash. You need to be a bit careful with however Each Firefox process might consume hundreds of megabytes, and with that property set to 16, Firefox can spawn a total of 17 processes, 1 master process and 16 child processes (=tabs). So force-enabling Electrolysis can only happen at your own risk! To enable the feature, open about:config, confirm the prompt, and then change the following properties as shown, create them manually if they don’t exist yet: trueī-enable trueĮxtensions.e10sBlockedByAddons falseĮxtensions.e10sBlocksEnabling false Of course, this is not officially supported, not on XP / XP 圆4, nor on Vista.

I’m happy to announce that it does work with Firefox 52.0 ESR though! This is a feature that makes Firefox more crash-proof and faster as well.

I tried that before with some 50.x version and failed to have Firefox spawn multiple processes for multiple tabs. On top of that, I have reevaluated the functionality of Mozillas’ multiprocessing technology on Windows XP 圆4 Edition. That is, unless somebody provides patched builds, but I don’t think that’s gonna happen… Firefox 52.0 ESR reporting is version (Click to enlarge)Īccording to the, security updates will be provided for XP/Vista up until September 2017, and the actual, exact EOL date will be fixed mid-2017.Īfter that, there will no longer be any modern browser support for XP (NT 5.1), XP 圆4 & Server 2003 (NT 5.2) as well as Vista and the first edition of Server 2008 (NT 6.0).
