After suggesting a few alternative download links the other day for Firefox themes, I had a few people e-mail me and asking, “How do I install these themes on DeviantArt?”.
Well, with DeviantArt and other places where you download a zip there is an easy (yet a little longer) install process.
For an example, lets say we just downloaded Castripe-iga 2.2 for Firefox. Now you have a zipped up file sitting on your desktop and you don’t know what to do next. First I want you to open up that zipped up folder and search for a .jar file. Drag that out of the zip file and onto your desktop (or export the file from your zip archive, different unzipping programs might do this differently).
Once that is done, open up Firefox – then go to Tools > Addons > Themes
Next drag and drop that .jar file you found earlier and put it inside of the window where you see all of the themes listed. A new familiar box will pop up saying that you have new software to install. If you have installed extensions or themes before – this window should look awful familiar.
Then, the only thing left to do is install it, restart Firefox – pick it as your theme and then restart Firefox again. Once that has been done your new theme should be installed.
Tip: Always check the .zip file you download for a “read me” file with any special instructions. This can save you a lot of time down the road and might give you more tips on how to personalize the theme a little more.
