This just made my life so much easier, thanks for posting this. IT Glue recently introduced a bug they have acknowledged where you can no longer hover over large images to see the full size, making half of our documentation illegible unless you want to force open the image in a new tab. This fixes that entirely.

I may as well post my must have extensions while thanking you:

DarkReader - this combined with f.lux on the machine will save your eyesight

SponsorBlock - makes youtube so much more usable, as well as other video sites

CookieNoticeBlocker - Im guessing there is a way to use ublock to achieve similar results, but it blocks those annoying popups for you

Behind the Overlay- useful for sites that use an overlay to hide article content, click the button and it hides any overlays and suddenly the page is there again

UnPayWall - find the full text to scholarly articles
