Observed behaviour

It is not possible to highlight and block any element on the page including ​http://cdn.mirs.com/images/tranzit/loading.gif image.

Reproduced.

ABP Safari provides the Block element option, but as described it doesn't appear to let the user highlight or select anything (there might be a flicker of a highlight along the left edge of the page but I can't tell).

There is a difference in behaviour to the same build on Chrome (43). In Chrome, the Block element option is hidden from the popup UI if the user back's to the loading page or stops navigation while on it.

ABP 1.8.12.1434
Safari 7.0.6 / OS X 10.9.5

There seems to be two (possible) bugs here (although it makes sense if this is due to some difference between Safari/Chrome):

• The highlight/selection doesn't work in Safari when stopped on that loading page (couldn't work out why).

• Safari behaviour doesn't match Chrome, which hides the Block element option on that page.

Note: It's harder to make Chrome stay on the initial loading page after going back, just keep hitting back/back/stop.

I'm closing all issues related to the legacy Safari extension, as it has been discontinued in favor of an App Extension that doesn't share any code with the old extension.
