Replace "eval" method

[Speravir]

Starting with Firefox 70 every script with "eval" will by default cause Firefox do not work at all (there is a config setting for developers, but this really should be used only when testing). Some of your scripts do use this.

I myself use your openNewTab.uc.js, where "eval" is used 8 times. A tip in a forum was to insert the eval code part into the browser console and copying the output (with some cleanup). Using this approach I was successful with some other scripts, but not with your’s. I had to add the functions and afterwards I do not know whether I still do need these. Also a question: Some of the "eval" calls are the same. Wouldn’t it be better to put them into a variable instead and insert this one into the places where the same "eval" call is used now?
