2057015 - In esr 153 the sidebar sometimes does not open and needs firefox restarted

Status: RESOLVED DUPLICATE of bug 2056857

(Firefox :: Sidebar, defect)

Description

[3wbzkafn6]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:153.0) Gecko/20100101 Firefox/153.0

Steps to reproduce:

It is random and usually happens after browsing and never when Firefox first opens. I have tried closing all tabs, and paying attention to which sites it happens on.

Actual results:

Peirodically the sidebar (which shows bookmarks) will not respond to clicking on the Show Sidebar icon to open it. It fails to respond until Firefox is restarted

Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:153.0) Gecko/20100101 Firefox/153.0
ESR

Expected results:

The sidebar should always open when the Show Sidebar icon is clicked. I have used ESR releases since forever and never seen this until 153.

The Bugbug bot thinks this bug should belong to the 'Firefox::Sidebar' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Unfortunately I can't reproduce.

Can you reproduce on a clean profile from the steps here? If you open the browser console (open with ctrl-shift-j), then try to open the sidebar a few times, do any new errors appear there ? In about:config, what is the value of sidebar.visibility?

Here is the error code it is returning every time I click the Show Sidebar icon. It is happening on two different computers with seperate profiles.

sidebar.visibility in about:config is set to hide-sidebar

It happens randomly. I used one computer for an hour with no issues. When I went to the other one which had been left overnight the sidebar was not working where it had been fine the night before
