Thank you for this extension, I do a lot of research on the net.
-- (it has inspired me to change the backcolor of my most used application a text-editor (Metapad3.6) )
Both BYM and ER are especially helpful late afternoon/early evening when my eyes are tired. Has taken a couple of days getting used to the two hotkey choices (easily customized in Options)
Color choices are easily customized in Options too.
I would prefer if the EasyRead/new-tab is created adjacent to the source tab and not after the last tab, because when the temp ER/tab is closed, active-tab defaults to the last tab and not the original source webpage.
With a lot of tabs open, it can be fiddly retracing back to the source page, sometimes a lot of tab-clicking looking for my original tab.
9/10 ... definitely a keeper + works perfectly in Palemoon and Firefox :)
