Oh goody, the “first time you search something, it will never complete” bug is back in Safari.
Work around: search it again in the same tab.
Not quite.
Using MR as an example, if I typed “macrumors” into a new tab, the progress bar will start, but never load the page or go past say, 1/8th complete.
If I pull up the address bar again and type macrumors into it again, it loads instantly.
No issues with searching here.
