In some websites the blue text-marked selection box doesn' appear

Works well, but it would be more handy to have it enabled for all websites by default!
This sole thing is very unconvienient, I'd love to modify that.

I miss the time it was integrated in FF preferences…

Can't drag video position on Youtube, after enabling this addon. Except this drawback, everything else works, even on some websites where other similar addons are unable to show the popup.

@Firebreathing, I totally agree with your statement.

I feel uneasy about this new permission all of a sudden and disable the extension for the time being until the dev explains or I find a replacement.

Before "Access your data for all websites" permission was NOT needed.

09 June 2019 - This extenstion has started breaking down fb page. With this extenstion installed and enabled, and both modes on, I can't post comments on FB. I then starten ff in safe mode disabled-enabled all extensions one by one, finding that only this extension disabled removes that problem, so this is the culprit.

couldn't find any kind of link here, to go to its website and post bug there, hence had to post here.

previous review - Why doesn't it offer "enable" and/ or "absolute" as a default for all sites? it is sort of helping sites in principle to block normal browser tools. bad policy. thanks.

Does not always enable image copy.

Not working everywhere.It a 50/50 for me.
RighttoClick was working much better.
Sometime a change to Waterfox only for that.
Firefox Quantum was the worst decision.
