Word-wrap problems, reading topics with Firefox browser

[Average Joe]

Hello, excuse me if this has been discussed before; if so I missed it.

Using Firefox (v1.0.6) to read Subsim forums, I'm having word-wrap problems. With certain topics, I cannot see the entire text on the monitor, and constantly have to use the right-arrow/left-arrow key to read entire sentences.

It's okay if there's only a few posts, but gets rough with multiple pages.

Losing word-wrap only seems to happen when 1024x768 images (from photobucket, rapidshare, etc.) are displayed in posts.

Even if only 1 image is posted, in a page full of text-posts, then word-wrap fails for that entire page, and text scrolls-off the monitor. If I 'Ad-Block' the single image, the page returns to normal, word-wrap works; all text is viewable again.

To any Firefox users; is there a browser setting (or custom extension) that forces 1024x768+ images to 'fit-to-screen'?

p.s. I'm running 1024x768 resolution on a 17" monitor. The word-wrap problem also occurs with Internet Explorer.
