Homer Simpson says to push the anger deep inside until it finally bursts out in a terrible rage like "when Daddy hit the refferee with a whisky bottle" (this may have been a whiskey bottle; he doesn’t specify). Well thanks for the advice Homer but in this case I’d rather just rant. It’s therapeutic (fun too).
Here I was trying to get my user stylesheet to work in Mozilla and nothing I did would persuade it to consider my ‘suggestions’. So after many attempts during which time I fell on my virtual ass many times (and my real ass once), I decided to create a new profile, on the basis that all of my screwing around (that being of course the technical title for my research) had broken something. Before I altered all of my settings for this new profile I checked that the rules set out in userContent.css were being obeyed. They were applied with all the giddy satisfaction that Mozilla always seems to feel when it completes a task successfully. So I began the Herculean, or perhaps Xenan, task of altering my settings. Disable popups; Don’t loop GIFs; Open tabs in the background; Change theme… Damn! My theme was ‘orbit’, which isn’t available by default. No problem, I’ve got it on this computer somewhere, I just need to install it. And with this simple thought I fell, once more, on my virtual behind. Mozilla does not, in fact, have such a feature that can install a theme that lives on the local machine. My journey of discovery had begun.
