Can you explain how to 'update the install manifest' - or in very simple terms, explain how to do that, or make ScreenGrab work again on FF 8? I downloaded the "screengrab-o.96.3-fx.xpi" but, it's not a recognised file extension, according to my computer or more importantly to ME! lol
Background: I just upgraded to FF 8 a couple of days ago, and when tried to use it today, I noticed it was no longer there on my right-click list! I'm also using Vista Home Premium. I haven't switch to using my "new" laptop that has Windows 7 OS yet (bought in the begining of 2011, so it's not really all that new now). It's being used as an expensive wireless device right now in my bedroom connected to my TV only so I can watch Netflix streaming docs at bedtime. Weird I know, but because I'm basically illiterate in the core workings of any computers, I've been putting it off because of all the work I think it will be to transfer my settings for all programs, plus to install any programs from disk that I want to take with me, etc. I don't want to mess that computer up and have a bunch of programs I don't use unnecessarily bulking up my hard drive like I have with this one. I also bought an external hard drive, but have not used it either. I haven't even plugged it in!
Ok, that's enough of that, weirdness. I just need to know how to get ScreenGrab back using FF8! LOL
I loved this tool, and just actually started using it a couple of weeks before I upgraded FF. I always upgrade FF when there's an update, but I don't do it on the first notification, instead I at least wait a few days to upgrade, hoping most bugs are resolved, and add-ons caught up and working. I was thinking of going back to previous version of FF just to get ScreenGrab back, but if I can use it with an adjustment, I'd like to at least try that first.
I did a search to see if I needed to download anything, and found this site, and this post, which excited me ---- well until I couldn't figure how to use it. :/
Remember, I don't understand much of anything.

Just that it worked before, and never do I go into the inner workings of my computer. I let the programs installed to that for me. Just like I did with the ScreenGrab add-on.
(lol, it's embarrassing that I've posted my stupidity online like this (especially using a laptop only for Netflex streaming, and only at bedtime!!!), but I'm that desperate to get the ScreenGrab back and working. lol
Thanks in advance for any help and or suggestions.
