Sure there are foss qr code generators, I don’t know any at the moment but with a simple google search you should find what you want. About the pdf on a specific page, I think you can add #page={pageNumber} in the url and should open it at the given page.
At work I use firefox, but to be fair we don’t have any firewall or restrictions. Home I use librewolf for privacy reasons.
Well…there are a lot of things I don’t understand, but maybe I’m just weird in that way :)) I don’t understand why some people accept that what they know at this moment is enough and don’t try to learn new stuff and be better tomorrow than they are now. I don’t understand why some people choose to ignore creativity and event think that creative people are childish or even stupid. And also, I don’t understand why lots of people choose to be jackasses and act accordingly to others when it would be so easy do not do this.
yeah, if I get that fork by accident I go and get another 😆
