Hi Chadwick, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
The second problem needs just a little clearing up, for me:
Is it the text in Opera, or the text 'everywhere' on your computer, that you need to have changed?
And how would you like it changed, please? to a LARGER FONT, or to darker, bolder text ?
The first problem... you need to be logged in to your Google account, for the Google Translate bar to show up in all web pages, I suspect.
I could offer Remote Access, if you'd prefer that, but I think both problems are fairly simple. I'm willing to be patient and explain stuff, at whatever level you prefer.
Let me know about the second problem, how you would like the text changed, please. Even with Remote Control Access, I would have to know how it is to be changed. Thanks.
