Yes - If it is FDM Plugin 1.5.7.5 it will allow current FDM stable release versions 3.9 or 3.9 lite (both are 'build 1249') - to work with all Firefox 15 versions - latest stable release of Firefox is currently version 15.0.1 and my FDM 3.9 + new Plugin version 1.5.7.5 works. Yes - Softpedia's copy should be the same as FDM Plugin 1.5.7.5 that can be downloaded from vaneo's link to the Firefox Add-ons site at top of this thread - which is where my copy came from last week!ĮDIT: The link in vaneo's original announcement above is a Firefox Add-on page in Russian - there is also an English language Firefox Add-on page at. I believe YES is the answer to both your questions - IMHO as ordinary FDM user trying to make sense of the rather limited information as best I can! I, and no doubt many other other more technically interested FDM users, would much appreciate it if you could explain how the new FDM Plugins actually achieve this.

but opening up the same new Plugin 1.5.7.5 prior to installation into Firefox shows only 'maxVersion' 15.*)

In discussion with other FDM users I/we also note that the new Plugin version 1.5.7.5 seems to be able to detect the FDM version installed and then alter the 'maxVersion' compatibility number in the 'install.rdf' file to suit? (EXAMPLE: FDM 3.9.1 BETA (build 1264 - one down from latest BETA) did not update automatically but when new Plugin 1.5.7.5 was downloaded the 'maxVersion' altered to read: 18a1. I also have the latest FDM 3.9.1 BETA (build 1268) on a Windows 7 machine - this updated completely automatically - but to a new 1.5.7.6 Plugin version? ('install.rdf maxVersion' now reads 20.*.*) ('install.rdf maxVersion' now reads 15.*) I then downloaded the new Plugin 1.5.7.5 from your link and this installed normally. When I ran 'Check for Updates' from inside Firefox 15.0 Add-ons Manager/Extensions 'No update available' was still reported. I note that my FDM 3.9 'lite' (latest stable version: build 1249) on XP/SP3 machine did not update automatically from the old version 1.5.7.4 Plugin.

Vaneo: Thanks very much for the excellent news in your post above and also for the link to the updated FDM Plugin 1.5.7.5 on Firefox's Addons website.
