Firefox spreading text across screen width

[ahenners]

As title basically. Been happening for a couple of weeks now but now its starting to annoy as it makes some webpages almost unreadable. Some bits of text are spaced almost as if to fill the width of the screen, whilst other bits of text are fine. Screenshot below to better explain it:



Is it just a simple setting that needs changing? Any help would be appreciated.

Thanks

Bizarre!

As a test can you try another browser?

Can you do a fresh install of Firefox?
