`JavaScript error: resource:///modules/AsyncTabSwitcher.sys.mjs, line 1187: TypeError: can't access property "spec", tab.linkedBrowser.currentURI is null`
eg of failure log: https://treeherder.mozilla.org/logviewer?job_id=421960149&repo=autoland&lineNumber=5342
Could the changes in this bug have affected these tests that are failing? They are several and across different components. 

There are also [these](https://bugzilla.mozilla.org/buglist.cgi?resolution=---&query_format=advanced&longdesc=uncaught%20exception%20-%20TypeError%3A%20this.mBrowser.urlbarChangeTracker&longdesc_type=allwordssubstr&list_id=16629759) new bugs that all have this failure line
