Here you will find others that have the same problem.
Myself, for one. I am now 76 and have been classified as 'legally blind' for several years. So I can not drive a car and I get a slight bark on income tax. I need to use a computer in order to read without a lot of eye strain and neck pain.
I used to copy and paste stuff from the current view and paste into notepad. That way I could enlarge the text for better visibility and not be hindered by pop ups and overlays.
Recently I notice some website do something to make it very hard to copy and paste a part of a web page. To date I have not seen any explanation of this.
The only work around I have is to use the 'select all' option. I use
ctl-A to select the whole page, including what is not in the current view. Then I have to paste into notepad and look for the part I wanted to read. Yes, the browser has a zoom feature that helps. But graphics and scripts do not work well with high zoom settings, Like a 4x zoom. It gets to be a mess.
When I paste into notepad, the graphics and scripts and special effects do not transfer. I get just the text. For some reason some websites do not allow me to select a portion of the ext. So I have to select all.
Maybe this would help you.
