hello chester122, please go through the steps discussed in Websites look wrong or appear differently than they should. this article lists the most common solutions for issues like the one you've described...

Hi

Thanks for the reply, I have tried all these steps and it doesn't solve the problem. I don't know whether I am explaining it properly. It's not making the sites illegible it's just really annoying. The site content is only displayed down the middle of the screen with the first quarter and last quarter being blank, I fear it may be one of those things I have to live with. It's just weird because I have never had this before on my old computer. It won't let me add a screen shot which would probably make it clear what I mean.

Thanks again

hello, well don't give up yet :-) it should be possible to add a screenshot at the bottom of the reply form.

can you please try launching firefox in safemode once and see if the problem is occurrig there too. Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

Hi

Just tried it and no different. The best way to describe the problem is - It's like when you have a wide screen TV and you switch it to the old mono setting, you can still watch but it's annoying and seems squashed. Does this make any sense?
