I have seen that in Firefox, actually. Not consistently or reliably, though. It seemed to me like it had something to do with running in full-screen mode, but I can’t make it happen again…
OK, I know exactly what you’re talking about. It’s due to the jQuery layout plugin I’m using for “panes” not loading correctly. I have *no* idea why it happens, because when it does (it usually happens infrequently when I’m on my development environment), there’s no sign as to why it is happening. I think it may be a race condition, but I audited the code pretty thoroughly and couldn’t find it.
The fix is to refresh the page, but it’s insane that it is happening at all. One day I’ll come across it and have a great insight and get it permanently fixed. This is how many of these perplexing bugs eventually get weeded out.
Before you refresh the page next time that happens, open the dev console and see which calls failed and the error code. Better yet, take a screenshot. Does this happen often, rarely, or intermittently?
It only happens when I load all the tabs in one folder. I have a folder with 13 links. The Newsblur page only throws that error when I right click–>Open All Tabs. If I open the same link by itself, no problem.
I’m not familiar withe the developer tools, but will try to do as you suggest. Need to do some further reading.
Oh fascinating! That’s because it isn’t allowing some JS to run because it’s own a background tab. It needs to hold on on running until the tab is foremost. I’ll noodle on this a bit.
It has started doing this in opera on Android for a couple of weeks. Every time I leave the tab open and return to it later.

I’ve also seen this error on Microsoft Edge [Version 89.0.774.63 (Official build) (64-bit)] on the Mac - the culprit was the “Super Dark Mode” extension. Once I turned that off and reloaded the page, it loaded up fine.
