Why is there no Option to "always translate this language". Its very inconvinient that i ALWAYS need to go to options --> always translate this website --> go back ---> translate. Why not just "always translate this language" ?

不知道怎么样

Tried to translate document: https://ichbinanderermeinung.de/Dokument93.pdf
but the icon I clicked on had a sensitive pop-up that holds you hostage, while you are waiting for something to happen.
The first time I tried, it took so long, I decided to continue a game I have on stand-by, but the addon freaking ENDS!! With absolutely no result!
It might work on other pages, but this is the page I needed translated, now. :(
