Was working fine till the command for it overlapped with a firefox webpage command to pull up network.

Very useful. I can continue opening sites in tab. After a duration, depending of a number of tabs open, (all configurable) the tabs are closed, more memory is free ... You don't bother closing the tabs anymore and even after closing you can still find the urls of the sites you visited

Awesome. I never imagined how many tabs I could close for inactivity without it. Thank you by me and my ram.

Version 6.6.0 can't use shift right click to select all tab lock.

Found another problem don't know if it's just me.
My tab lock list is in reverse order when sort by tab order, need to sort in reverse to match my tab.

I have another add-on called session sync which I restore my tab in reverse restore order don't know if the problem is related.

But I don't have this problem when using version 6.5.1

Sorry for the long rambling.
Being a user with low spc cpu, rely alot on this add-on, that I couldn't resist posting my 1st review here haha

Thank you, issue is fixed and really like the new highlight for lock tab.

Import function Does not work, otherwise great.

Stupendous! Very well thought out! Best tab limiter/manager I've ever used. Closes tabs that haven't been used for whatever time period you choose yourself, but keeps a database of what was closed that is in effect just as if the tab was never closed, that you can see simply by clicking the toolbar icon. Tab gone? Okay, reopen it from the list. Tree Style Tab users: placing the icon right above the sidebar reduces the pain of looking for it. I keep mine right between the back and forward buttons. LOVE IT!!

Finally an addon where you can set seconds aswell. Needed something for quickly closing tabs, thanks a lot!

super efficient tab management, a must have for web browsing. being able to search is huge upgrade from "Undo Close Tab"

A great alternative to AutoClose tabs which is broken in firefox Quantum.

It would be perfect if you could lock tabs by double clicking them like in auto close tabs.

I love this extension, same as love this on Chrome. But there's one main issue i have with the firefox version. When watching fullscreen youtube videos, when the extension decides to close a tab, it takes you out of fullscreen, and this can be incredibly annoying especially when a bunch of tabs close all at once.
