I did download it but (and I know this sounds dumb, but I am very unfamiliar with how to do things with Linux/Ubuntu) how do I install this. It is currently saved on the desktop.

yes, I understand that I need to uncheck it, but how do I get it to stay unchecked?
it used to...

hopefully one more quick question
I just noticed that the "work offline" file menu is re-checked every time I go into my browser
how do I get it to stay "online" ?

just re-started the computer and I am online again

THANKS VERY MUCH
All of your help is very much appreciated!

also, not sure what this means, but the system will automatically check the "work offline" in the file menu every time I re-try getting onto the internet (mozilla firefox)

sorry, I have no idea

unfortunately, there was no change

sorry, I'm a newbie ... how do I do this?
