Hi Stefano, Nils here, long time no see. Yeah, it was 2006 when I joined you and Federico, if I remember correctly, while you and Federico started DownThemAll! in 2004. #201 is correct :D 2006 was really a long time ago... DownThemAll! went through a lot of revisions since that time, including the work it took to make it restartless, then make it compatible with "electrolysis" and so on. And in the meantime ensure it…
> I am still not happy mozilla decided they had to break all extensions Actually, the weird thing - for those who see FF or TB from the inside - is that the same kind of code we have in regular extensions is still what's used in FF and TB's own chrome (which is in many ways like a bunch of "core extension"). They haven't changed things in a way which makes using extensions impossible, they simply removed the loading…
One of the core technologies of the old extension model, XBL, has been completely ripped out. XBL-defined elements and XBL overlays were how a lot of the old UI customisations functioned, so even if you enable loading the older code it just flat won't work. Obviously custom JavaScript, as in the example you linked, can still do whatever when loaded without restrictions, but then you're at the mercy of changing internals, instead of the supported stable WebExtensions API.
Additionally a lot of XUL in the chrome UI has been removed, replaced with HTML equivalents or custom elements (a descendant of XBL), and the root documents that make up the browser chrome have transitioned from being .xul XUL documents with some HTML elements in to .xhtml HTML documents with some XUL elements in.
