Web Page Fixer + 1.7.2
This add-on will fix many web pages that don't show up correctly. It extracts MS Office-exported html (Office Web Components), and fixes many "Internet Explorer only" pages and other web annoyances. For example, you can use this addon to turn symbol font-symbols into standard viewable symbols, and you can set it to turn image alts into tooltip titles so you can see the alt text for images. Other features include downloader fix and blocked-link security alert.
