So I created a Safari Web Extension. I did not change any piece of code and ran the template code provided by Xcode.
I clicked on the toolbar item and a blank popover window popped up. It took around a good 5 seconds to load the "Hello World!" screen (It is the screen that is the part of the template Xcode provides).
After that, whenever I again clicked on the toolbar item, the "Hello World!" screen popped up immediately, but Safari did not respond until around another 5 seconds.

Is this a bug on related to Safari or am I missing something?
I am using Xcode 12.2 and Safari 14.0.1

Yeah the popup is pretty slow on launch in compare to chrome. Chrome launches my extension's popup in almost immediately, while safari takes at least 1.5s.

I've also opened a feedback for this issue: FB8976225. The 1500ms or so delay is super noticeable.

We are experiencing the exact same reports with our Safari extension ever since migrating to Web Extensions. It appears that Safari is spinning its wheels with each open of the pop-up for about 1.2+ seconds or more with each click, before even making the first request to fetch index.html and render.

See for reference (also a link in there for a timeline recording): https://github.com/bitwarden/browser/issues/1732.

Has there been any progress on this issue or movement on the feedback issue(s)?
