I finally found a download accelerator that will work with SRWare Iron 5 Alpha and Firefox 3.6.3
It's
Internet Download Accelerator.
It does have some annoying features. Adds in the progress dialog, silly sounds, insisting on categorizing downloads unless you put them in a dated subfolder, sticking toolbars in Firefox.
But you can turn the sounds off at least. What it does without using Flashgot or any plugin(when I say without using any plugin I mean, after you remove the stuff it sticks in Firefox AddOns.. just uninstall them,) is follow redirection on downloads from AfterDawn in both Firefox and Iron.
The main annoying thing is it insists on opening a white web page telling you it's taking over the download. Evidently you have to pay up to get rid of this notification page(like when you try to disable in the settings it tells you only the Pro version lets you disable it.)
But, It's the only one I've tried so far that actually works in both browsers. All the others I had to drag a link to the drop box and that doesn't work with AfterDawn downloads or other sites that fetch with JavaScript. At least this one does. Looks like I'll run it until I find something better.
edit: Looks like it can find Iron on Vista, but not on W7.
edit2: Also it looks like this download manager free version is a lot slower than Free Download Manager. The moral I guess is, if you want speed you have to drag the link to the FDM drop box. I guess I'm going to uninstall this thing. It's too slow and annoying for what it provides.
(p.s. sorry to hijack your thread but I thought you might be interested in how Iron fares with common tasks.)
