Works as described. Replace method doesn't mess w/ Google Translated webpages' formatting, so I can use Stylus to get rid of those annoying paragraph indents.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

FoxReplace requires a few sensitive permissions. Exercise caution before installing.
