UPDATE: right after writing this review, I discovered that I had Debug mode enabled (not sure when I did that). After disabling the debug mode, everything seems to be back to normal.

It works fine most of the time, until, randomly and out of the blue, the display of tab groups and tabs would show additional information in front of the tab group or tab names.

For example, if the current tab title is "Simple Tab Groups...", what I saw on the tab name in STG is "@1:#1495:i1487 (36:3.570)Simple Tab Groups..."

It looks like the info before the ")" is a kind of a tab number and the info inside the brackets are a time stamp (minutes:second). The actual tab/tab group name did not get modified, but these annoying, additional information is displayed.

This have happened multiple times already. The work around was to restore from previous backup, and it would work fine, until the next re-occurrence.
