It seems it is only when I open a new tab, if I go to a tab that is already open and tell it to open something in a new tab, it opens and loads, and then I can use this new tab to go to any other website.

Just writing to report that there were several updates since this started happening and none of them fixed it.(it started somewhere around the third beta version for 56)

I have the same problem. Only happens on new tabs, not new windows. Neither direct url nor clicking bookmark will load the page in blank tab. Site loads if the tab is not blank(new).

edit: works fine from 7th of october. thanks

When I'm browsing on Pinterest and find a pin I want to read, I click on Read More or Visit or whatever button. It then opens a new tab, goes through the process of loading. The new web address is loaded into the browser bar of the new tab, but the page is blank. The new site, from clicking the button, doesn't open/show up, in the new tab? Is there a way to fix this problem? I've been in contact with Pinterest thinking it might be something on their end, but everything they've suggested hasn't worked.
