a very specific Firefox question

Thanks jewels - I've used both of those and neither did exactly what I wanted. Believe me, I scoured the add-on website for anything that sounded remotely close to what I needed.

I forget which one, but one of them didn't recognize the text on the site I want to use it on, it searched just for paragraphs - and the other just took too long to right click and "activate". They may be useful for others who have a different purpose in mind, however. I did keep the Book Text Mark to enable for other uses. Great to have when my blog reading is interrupted by a phone call.

I guess I kind of solved my own problem to an extent by playing with Firefox options so I'll post my solutions here in case anyone else is curious - 

First, by disabling (unchecking) auto-scrolling. This makes it so that when you're on a webpage and scroll to a certain area then refresh, you're taken back to where you were rather than at the top of the page. Most people likely know this, but I had no idea what auto-scrolling meant.  This would have been great on the old eBay - when the price was a bit further down and you had to scroll to see it. I was a bit of a sniper back in the day, doing those last-10-seconds bids and that required a LOT of refreshing/reloading the page.

Secondly, full-screen mode. Pressing the F11 key. That'll get you more content on a webpage depending on how much you have up there on your toolbar to begin with.

I'd still love something that would do it all faster, but these were useful discoveries for me that will make do for now.

Thanks for your input jewels!
