I found this solution to my browser sucking up resources about a year or so ago.
I run/allow it in private browsing mode, never an issue!!!!!

I have never had an issue until today!

Firefox now opens two windows instead of one as of tonight when I get home 3-5-21.
Disabling extension fixes it, enabling reproduces it.

Using Archlinux - EndeavourOS - 86.0 (64-bit)
KDE Plasma Desktop

Extension desperately needs better handling of Private windows. OneTab will not on load Private windows, even if given permission to run on them.

Additionally, it can attempt to open itself in an already open private window when selecting "Display OneTab", resulting in a mostly blank but completely useless page.

Finally, left clicking the OneTab icon in the browser toolbar saves all tabs in the current window to OneTab, then closes the window without asking for confirmation. While I do not believe this to be *good* behavior in principle, it's also worth noting that the top option in the menu when *right* clicking the icon is "open OneTab", and it'd be reasonable to expect that to be the default, left click behavior.

Ideally, I'd like OneTab to understand the difference between a private tab/window and a normal tab/window, or at the very least include a "restore/open tab(s) in a private window" option. Hell, failing that, I'd accept a version that commits to the private browsing sandbox: onetab saves you tabs in a private tab/window, and closing out your private session completely wipes it.

In short: addon falls short if your, uh, heavy memory usage tabs are in private browsing windows, suffers from some minor interaction woes, and could use some options to better define its behavior (specifically that left-click on toolbar issue and auto-closing windows (would like option to keep window open with sole OneTab tab open, for example))

Buena; falta arrastrar pestaña a onetab.

The new release is incredible. No more load times, always active, and extremely stable.

Reinstalled firefox. All my other plugins' options got synced and restored seamlessly, but i seem to have lost all of the tabs I had in this addon. I understand that this data is stored locally only, but it would have been nice if there was backups or something built-in.

Hi! First of all, your extension is perfect and really helps me every day! But could you implement a simple night mode ? Actually that's the only thing OneTab is missing :)

Very useful extension! Has been very reliable and saves me from constantly emailing links to myself to "visit later".
Suggestion: Would be wonderful if you could specify which open tabs should be added to OneTab, as opposed to sending ALL open tabs to OneTab.

Nice tool, but i missig a chance to group my tabs.. after starting addon my list contais more than 80 Tab . Thats nice but without any chance to order by categories.
some of my tabs are needet for read later or redraw .. ff speed increases realy because of much less memory needed but the list is confusing.

A lot of us want a button to send one tab to the list instead of all the active tabs

Would be awesome if we could convert just one tab with a ctrl+clic for example !
