So sometimes you need to use more than one of them. Presumably they’ll finish migrating from the Flash client before it can’t be run at all on an Enterprise Desktop. But the HTML5 web client works fine for almost all day to day tasks already.<br> <p> Ewen<br> </div> Sat, 21 Nov 2020 06:53:40 +0000 No more Flash support in Firefox https://lwn.net/Articles/837874/ https://lwn.net/Articles/837874/ cpitrat <div class="FormattedComment"> 15 years ago I remember I was using a GNU alternative to the flash plugin.

Or, potentially, port an old browser to WebAssembly, which avoids having to reimplement the interaction between Flash and JavaScript (which some old content relies on). Both of those might be substantially easier than reimplementing the Flash player itself.<br> </div> Thu, 19 Nov 2020 08:36:04 +0000 No more Flash support in Firefox https://lwn.net/Articles/837709/ https://lwn.net/Articles/837709/ roc <div class="FormattedComment"> Also the DRM blob is only needed for ...

When I finally got woke and realized it truly was a flash web site, and installed flash to use it, all those bad memories came flooding back -- no bookmarks, sucky scroll bars, terrible fonts, shaky cursor, so many stupid little upsets and failures.

But a lot of the use of Flash was simply showing video files.

With the slower CPUs then, the binary Flash blob would often struggle with fullscreen resolutions anyway.<br> <p> Flash is gone, but this strange idea of putting videos on web pages hasn&#x27;t gone anywhere.
