The Benjamin

(black text on white background)

Extension to delight @danbenjamin of 5by5. Functionality is pretty straightforward here...activating the plugin will attempt to take the page you're viewing & update the css of elements which are white text on top of black/dark backgrounds, and turn them into black text on a white background.

There are a couple of other style changes that take place - removing some background images & updating link styles - but it's all pretty basic.

Gmail photo attachment rotate

Annoyed with when clicking "View" on photo attachments in gmail & them coming up sideways in a new tab, i wrote this to one-click rotate them for better viewing (works with multiple photos).
This seems to happen for me any time an iPhone email with photo attachment is in question.
