Clicking pages always highlights them

[CZeke]

Whenever I click to go to the next page, the whole page container gets highlighted in blue and stays that way until I click elsewhere. Anyone know why that happens, and/or a trick to stop it? It doesn't happen with keyboard shortcuts, but I like reading without my keyboard attached.

(Browser: Firefox 55, not in a position to update right now. This seems simple enough that there must be a fix regardless.)

Try visiting

about:config

and setting

layout.css.prefixes.webkit

to

true

? At least, that's what MDN seems to say

Thanks, but it was already on true. I tried swapping to false and back, restarting the browser each time; no effect.

Some sites add css-rule to make text/images "unselectable". Do you use usercontent.css fix for this by any chance?
Something like

* { -moz-user-select: auto !important; }

? That was reason in my case. Too bad ability to copy text is much more important for me than this minor issue :/

Aha! I wasn't doing exactly that, but I use an extension that has the same effect. Disabling it fixed the MangaDex issue.

Like you, I hate sites that disable basic web functions and I value my ability to tell them where to stick it... but now that I know this extension is to blame, I'm sure I can figure out how to make it ignore this site.
