This addon enhances Firefox's native Open Plain Text Links behaviour to work automatically for simple http and ftp links. Firefox can already open plain text links if you fully select them first, but that's a bit of a pain to do. With this addon installed you just need to right click on one and it will give you the normal link opening menu items just as if you had selected it first.
Less easily-recognizable links (for example, missing the http:// scheme prefix) can still be opened by selecting them first; the standard Firefox behaviour.
This has been delisted by Mozilla, and is now available as a UserChromeJS script from https://github.com/xiaoxiaoflood/firefo ... js-scripts
