I use google chrome, things might look a bit different if you use another browser but it should be pretty similar across the board I would imagine.

find what you want to download (this is a world. obviously), right click the page itself and press 'view page source' (or press ctrl + u if you're a shortcut gamer)

this opens a new page, next thing you're gonna do is press ctrl + f to bring up the search bar in the top right of the page. search sims3pack and it should bring back at least one instance (sometimes there are two, if there's multiple you can use either link; it's the same one I'm pretty sure)

highlight the link that ends in .sims3pack (don't include the quotation marks or anything else, you literally just want the link) and either copy + paste that into your address bar, or right click and press 'go to insert link here'. it should just start the download from there.

sometimes its a bit finicky and brings back an error page; usually switching users on google chrome or opening an incognito tab fixes this for me.
