Recently I have found some computers on which, due to their performance, no superior operating system can run. For all those who are in the same situation or who simply want to use Windows XP for nostalgia or on a VM, I leave you the list of all (or almost) the browsers you can install.
I just don't understand why both of the updated XP browsers are based off of an engine that's only really good for email clients and embedded browsers. Pale Moon is kinda trash when it comes to a main browser.
With Chrome and Firefox for Windows Vista not receiving security updates, it leaves users with a handful of options. But we did some research and found the best browsers for Windows Vista you can download and use right now.
While we have covered the best browser for Windows Vista, if you have a PC running equivalent or even an older generation of Windows OS and are looking for a list of the best browsers, check out our carefully curated guide that lists the best browsers to use on old and slow PCs.
Update 2009-12-06: apparently, the order in which the browsers will appear will be random, and might no longer show within an Internet Explorer screen. The final version might get EU approval on December 15th.
(I wonder how those who cannot install a browser themselves are now expected to select the best choice given the advertising slogans. And what if your second choice will actually make itself the default browser? I don't really like this push towards existing users: why confuse them, and what if a Super User already installed another browser at someone else's computer?I also wonder if all browsers are actually available in localised versions; changing "_en" in the URL into something like "_fr", "_de" or "_nl" will give the same list, partly translated, while "more information" then still links to an English page. But: this might not be the final version. Even more: maybe it's just a demo, and not the real thing. I'm quite curious if one could really skip this step during first installation.)
Important: QuickTime 7 for Windows is no longer supported by Apple. New versions of Windows since 2009 have included support for the key media formats, such as H.264 and AAC, that QuickTime 7 enabled. All current Windows web browsers support video without the need for browser plug-ins. If you no longer need QuickTime 7 on your PC, follow the instructions for uninstalling QuickTime 7 for Windows.
My Firefox ESR v52.9.0 browser has built-in support for H.264 (using Cisco's OpenH264 Video Codec) and is included in the list of compliant browsers at I have no problem playing HTML5 videos on websites like YouTube and haven't needed to install the Adobe Flash Player plug-in in my FF ESR browser for a few years now.
Just be aware that Mozilla ended extended support for the Firefox ESR browser on older Win XP SP3 and Vista SP2 operating systems on 05-Sep-2018. From the Mozilla support article Important - Firefox Has Ended Support for Windows XP and Vista: "Unsupported browsers receive no security updates, have known exploits, and can be dangerous to use."

I still wonder what browser(s) you were trying to use previously (other than Chrome). My best guess is Internet Explorer 7, unless maybe you never installed Platform Update and Supplement (e.g. see -video-playback-under-vista/). If you don't have Platform Update, chances are you never installed any Windows updates more recent than SP2. By the way, every browser that works on Vista is outdated now (not just Chrome 49), including Firefox 52. At this very moment I am using Firefox 62 on Windows 10.
No real surprise, but various other browsers should also be able to play H.264 videos on Windows Vista. Since no specific non-working browser has been mentioned, I will post some general information (using the past tense for obvious reasons), at least some of which must be related to your specific issues:
Browsers that supported Windows XP, such as Chrome 49 and Firefox 52, typically installed their own H.264 video decoders. Aside from IE9, only two browsers supported Windows Vista but not XP: Pale Moon 27 and Slimjet 12. Those browsers did not install a superfluous H.264 decoder because Vista already had one, assuming Platform Update was installed (a doubtful assumption now that Windows Update has been dysfunctional on Vista SP2 for three years, and btw Platform Update was a prerequisite for IE9). The 64-bit version of Palemoon 27 did indeed have a video issue (see =17939), but the 32-bit version worked perfectly on Vista SP2 with Platform Update. If you were looking for a 64-bit browser other than Chrome 49 for Vista x64, then I could only suggest one of developer roytam1's browser variants (Firefox 52 being available only in 32 bit). His "New Moon" 27 variant was developed to support Windows XP and did not support Vista's system decoders, instead requiring do-it-yourself LAV decoders (see the first FAQ on page 1 of -my-build-of-new-moon-temp-name-aka-pale-moon-for-xp/). His more recent variants include decoders, so you should start at the end of that thread instead of the beginning.
Firefox is one of the few browsers that continues to support Windows XP and Vista, and we expect to continue to provide security updates for users until September 2017. Users do not need to take additional action to receive those updates. In mid-2017, user numbers on Windows XP and Vista will be reassessed and a final support end date will be announced.
