Rot13

Works great, even when the text has numbers, symbols etc (obviously any non letters aren't changed) and it does work when submitting text boxes

Works to un-ROT, but doesn't ROT very well. No use for Facebook.

Doesn't work.

It works sporadically (often seems to only work once on a page, or possibly there is a formatting or punctuation issue that breaks it), sometimes not even able to flip back a text it just flipped once. It also strips out all formatting in between, so if I highlight a string of three comments, they become all one paragraph with the user icons removed. As I use this on Mark Reads, a community that uses partial rot13 to obscure parts of long conversational threads, this is not robust enough for me.

It works, and doesn't need any permissions.

Doesn't seem to work if any of the highlighted text contains punctuation. Makes translating paragraphs, or eve words with apostrophes, inconvenient.

Works!

worked for me! the only problem is rot-13ing in a text box will work, but it doesn't actually change it's value, so submitting the form it's in will still be un-rot-ed

Didn't work when I tried it. Selected text, right click, selected Rot13, the text just disappeared.
