Очень удобное расширение. Помогает в повседневной работе при сёрфинге в интернете.

One of the extensions I install first.

one of my favorite and must have addon

Good! But I also want to mention that you can hold "Alt" and select text in links in Firefox now. (At least it appears so.)

I give this extension five stars because it works well and it really solved my problem. Many thanks to the developer.
