@leocg Ahh, I tried looking for the issue in this forum, but couldn't find anything. So, I only see posts describing the issue- I take it there is no solution yet?

Yoo, guys look at this, this can't be normal. There are probably 150 sessions in the "Tabs" section of the sidebar. It doesn't seem to affect performance, unless I click on it and scroll around; that's when all the sessions seem to load.
I checked the %appdata% folders for any convoluted files, but I can't seem to find the correct location. Please help me to close these sessions, it's annoying.
