Honestly, this is something I didn't know I needed until I decided to try it out. Lets me easily see what kind of Firefox browsing window I have open, whether it's mostly an entertainment window or just a random browsing window. Essential for someone that likes to have multiple browsing windows.
Though it is a great add-on, it could really use more symbols and colors. I find I struggle with categorizing entertainment-type tabs. Overall, great.

It does exactly what I wanted, but working with it is so cumbersome. It requires too many clicks for simple operations, like opening a tab in a specific container, or switching containers. I think having windows that will open by default the selected container would speed up my workflow. It should also come up on more contextual menus, and definitely showing your options directly, and not as a submenu. It works flawless and it allowed me to ditch Chrome, which is what I wanted, but the UX is not as good. I am looking forward to seeing this extensions as part of the stock browser having a much better integration.

add proxy each container,
add canvas fingerprint different or random each container,
add user agent different or random each container,
sync to firefox acc or local file backup

will be perfect!!!!!

Awesome add-on! Love it! Looking forward to "Replace a tab with a container tab" feature, and more shortcut support.

This such a great extension. I only wish I could "Replace a tab with a container tab" instead of reopening.

Great add-on, but I wish there was a way to store container settings across multiple devices. The lack of this feature is the only thing holding it back from a full 5/5.

Very nice, BUT missing essentials: container preferences sync + container reordering. Moreover, mobile support + temporary containers could be a much desired addition.

It's awesome, but why can't we change the order of the containers in the containers list? That UI feature should be a no-brainer...

This is a great tool that I use everyday to sepperate personal from work, secure from face.. insecure and so on.
My only issues would be that when I open a site from default I cant then assign it to something and have it moved to that tab, my second issue is that after I set something to always open in a container I will get the notification on next launch asking if I want this.

Other wise this is an amazing tool.

Bugs: (None so far)

Cons:
- No dark theme compatibility, it's almost invisible on dark backgrounds.

Pros:
- It's fairly straightforward to set up; and once set up you can forget about it

I like the functionality, but I don't like one behavior. I open a work tab to open gmail for example, but it reopens the site in personal container, which is annoying. If I am in a container specific tab, especially a new tab, the site should be opened in the same container.

I will not longer be able to live without this extension.

Things it really needs:
- syncing between Firefox instances
- a better icon for dark themes (it's invisible)
- more colours and icons for tabs

This is a very nice tool. Removed a star because it does not sync between my PCs using Firefox Sync.

Bug: Infinite loop for auto-open websites.

I have amazon.com set to open up in a "Shopping", and aws.amazon.com set to open up in a "Cloud" tab. When signing in to AWS, the tab gets stuck in an infinite loop of switching back and forth between a "shopping" tab and a "cloud" tab.

Would be 5 stars if container info was synchronizing with firefox account to other computers

在“Open this site in your assigned container?”页面，选择后一个选项时，极大概率会出现点击无效果的情况。

Very useful! But I would like to be able to sync the configurations between devices, and to have the choice of some predefined rules. Such as "every google page in a Google container". Also, I have a bug when I create such rule on a google page, and that I have a page that automatically redirect to another container page. The new container page is indeed opened in a new tab, but the previous tab is not closed...
