UPDATE! This question is not marked as answered, as the issue is a new 'feature' of Firefox 22, and if you read all the comments you'd see that. Clearly, with the large volume of 'new' answers coming in saying the same thing over and over, people aren't, so I'll say it here: THERE IS NO NEED TO ANSWER THIS QUESTION ANY MORE.
I recently asked about my UI being big and fuzzy, and managed to get that fixed in the about:config, but websites are still big.
For some reason, the default zoom (ctrl+0) is at 120%.
I tried the FullZoom and NoSquint addons, but both had one issue. They messed up the top level image view (which for me works with the old default image style addon) and made the unzoomed image a bit bigger than my screen, and the magnifying glass icon which should appear with a + or - in it when I mouse over the image is just a regular mouse pointer instead.
How can I reset the default zoom to be 100% (or preferably about 80% because even 100 seems to be overcompensating for my high dpi screen) without an addon messing up my default image view?
Further details. If I disable the 'old default image style' addon, the top level image view works fine with the NoSquint or FullZoom addons.
