I really love the addon, but I since I couldn't find a bug report, I write here:
I updated Firefox and the OneTab list is empty now. I hope, that data is still somewhere. Hope, that it's just a glitch, where it's trying to open it using the wrong path, but I cannot find the data files where all the saved urls are located. Please, help.

good extension

Love it, but needs a new and better looking icon

I love this addon, it is one of the best for Firefox. I wonder if there is no way to duplicate the onetab tab in different windows. I use two monitors and I find it essential. It could be done? =)

OneTab works great for grouping tabs & saving memory. It's the best extension for this in my opinion.

A few features that I'm missing though are:

- Sorting tab groups by drag & drop.
- Moving multiple tabs between tab groups in one go.
- Export/Import as JSON.

Extremely useful extension to declutter Firefox and free up lots of memory. It has issues, though, like some times not loading or stopping working (requiring restarting several times) and not saving/restoring the tab's original container. It could have an option for default behaviour for icon clicking (e.g., storing only current tab or opening OneTab.)

Отличное расширение. Немного напрягает, когда случайно нажимаешь на кнопку приложения в панели меню, и все открытые вкладки сразу закрываются. Потом приходится восстанавливать. И не забывайте делать бэкап, на всякий случай, это очень просто! Добавлю, что пару раз с приложением были проблемы, один раз просто заруинились вообще все мои закладки,сейчас вот стало работать некорректно, не могу добавить новые вкладки, переустановка приложения не помогла.

Very useful - would be better if you could move multiple tabs at a time within the lists, it's a pain to sort them one by one

It's great, but would be better if there is an option that makes left-click on the icon send only current tab to one-tab, instead of all tabs

wake up people! awesome add-on espescially with porn...lol

Found out why OneTab wasn't working entirely by accident. Still disappointed by the lack of response from the devs. If anyone else has an issue with OneTab not loading, though, try this:

"I'd changed 2 settings in about:config

image.webp.enabled was set to false (default true)
image.http.accept was set to "*/*" where the default was "image/webp,*/*" - all without the quotes"

I found this for a seemingly unrelated problem with YouTube thumbnails not loading, but sure enough it also corrected my OneTab issue. No idea how the settings were changed in the first place.
