"This page was reloaded because of a problem" on every page when using latest Safari extension

Hi kevin_li –

the suggestions in that post I see are to:
1. Clear the cache (which I already tried)
2. Clear all history
3. Delete cache file manually in system files
4. Disable extensions one-by-one

These options are very invasive – clearing my history would clear all autocomplete suggestions in the address bar, which I rely on daily for my workflow. Deleting a file from system files that essentially is just the same as clearing caches seems unnecessarily risky if emptying caches already didn't do anything.
And I already disabled extensions one-by-one and found out that it is specifically the 1Password extension causing this.
As such I am hesitant to try any step like deleting all my history if there is no indication that might fix it.

Speaking as a web software engineer myself, an error like this happens when JavaScript that runs on the page enters an infinite loop. If this only happens when 1Password is clicked in the UI, but never when the extension is off, then that means that it is JavaScript that 1Password runs on the page on click – meaning there must be a bug in the 1Password's extension's JavaScript code.

Are you able to reproduce this issue on your end in the same Safari version?
