Tor and Firefox browser in Tab

I have Firefox 150, Tor 15.0.15 running on Debian 13 and with XFCE 4.2 I noticed that the when I have Tor and firefox both running that the Tab icon for Tor disappears into the tab for firefox. If I click on the firefox tab icon Tor appears another click on the same tab Tor will appear. This happens occasionally after running both and shifting around from workspaces.
