[FIXED] "List all tabs" button won't show any tabs (fedia.io)

In the latest Firefox version(116.0.2 (64-bit)) the button "List all tabs" won't show any tabs unless I close like half of them, then it works again if I open new random tabs. Currently 246 open tabs.

Any other way to fix this? I don't really wanna close those tabs.

The way I know this is that I tested in a sandbox with the same profile to try to find the problem.

EDIT 14/Aug/2023: So I just found out the issue was some tabs that had a " --" at the end of the title probably caused by some addon made this issue happen. It probably isn't really a - but I don't know what character is that.

All you have to do is just copy the url, open a new tab, paste the url and go. Close the previous tab with " --" at the end.
Just make sure you are not opening a new tab with CTRL+(clicking the + icon) from the "broken" tab with the " --".

Example.

Hope this helps someone else.

I don't know whether any errors would be recorded when Firefox tries and fails to generate the list. While viewing that window, you could open the Browser Console popup window (Ctrl+Shift+J), then click the List All Tabs button in the main window and see whether any error messages appear in the Browser Console in response.

Although i managed to fix the problem, I went back to test it and indeed it gave an error:

TypeError: lazy.ContextualIdentityService.getPublicIdentityFromId(...) is undefined3 TabsList.sys.mjs:323:40
_createRow resource:///modules/TabsList.sys.mjs:323
_populate resource:///modules/TabsList.sys.mjs:110

dispatchCustomEvent resource:///modules/PanelMultiView.sys.mjs:189
dispatchCustomEvent resource:///modules/PanelMultiView.sys.mjs:1484
_blockersPromise resource:///modules/PanelMultiView.sys.mjs:223

The fix is in the edit above.
