It only works for a short period of time,then the pop up box, to select the container you want comes up as a blank white box,it happens every time I've loaded it & reloaded it & cleared caches & refreshed firefox & reinstalled all add-ons 1 by 1 & it doesn't matter it always happens & you lose it & all the other mutli acct containers that are based on the same code, so I can't open certain sites now,when the tab is closed I can't go back into container so I can't safely use my social media, thanks, can you fix this shit? asap & I'll change my stars to higher 4 or 5 likely but as it stands I give a 1 star since it's not only unusable it's preventing me from even logging into my social media totally..& safely

очень жаль что невозможно использовать в приватном режиме. Я ВСЕГДА запускаю браузер в приватном режиме и использую мастер пароль для моей безопасности

I have tried this addon on two of my laptops. Both systems stops responding shortly after installing and remains in hung state for around 20 minutes, then firefox crashes and system comes back to life.
using ubuntu 20.04.
Edit - Now that i have deleted add-on. it is still showing container option in right-click menu!

Since Sync feature was introduced for this add-on the container flag no longer comes back with session restore.

When I use containers that were created some time ago, tabs re-open in those containers, correctly.

When I create new containers these tabs open in normal tabs when the session is trestored, so the container flag is lost for them.

Whatever may be the difference between older and newer containers - since the sync feature was added this behaviour is happening, rendering the add-on useless in my case.

It was more annoying than anything else. Once I removed it, I had to restart Firefox 3 (three) TIMES to remove it from the context menu. Once should be sufficient. Certainly not twice, and definitely not THREE times.

The latest update ask for permission of 'Exchange messages with programs other than Firefox' and 'Control browser proxy settings', which is ridiculous for people who do not use Mozilla VPN.
It should only be an optional permission!

Cannot save settings for multiple container of a same site. And when I reload, the duplicates will gone or will only use one container.
Which is not what I expected. Well it does what it does but the way it does it makes me think the title is a bit misleading.
Multi-Account container? NO just call it Firefox Web Container please. Or Firefox Multi-Web Container.

why did you remove this functionality in the newest update to Firefox? why are you making the program worse rather than improving it?

Buggy as hell. Cors Issues and more than 400x issues not resolved. I don't understand how this extension can be recommended. The extension is broken by design and a pure non-sense.

this add-on has many issues which I've already submit on issue list. also many open PR with zero actions, add-on seems doesn't active.

Horrible for google accounts.

It was never a really good extension, but with the new update it bacame totally unusable. how can you make such a small plugin so complicated and unintuitive, quite impressive

"Here you can go back to the previous version"

Remember to activate tab synchronization

it's useless now, please remove this extensions upload old.

How is this a Recommended Extension?

Mozilla doesn't have to follow their own rules?

This problem has existed for so long and apparently no one knows how to fix it.

And now you got the new Ui problem and new glitches, just check the recent reviews. So glad i knew not to update.

It went from being a good extension to something really bad, with just one update

Their latest update made this extension annoying to use. As others have said, now I have to click multiple times to open a new container. I will wait for a few weeks just to see if they read our reviews, but if they don't, I will uninstall it. A shame, because I truly liked this extension.

After latest update hundreds of temporary containers keep on showing up. I can delete them but they are back after a restart. Really crappy update!

don't know what they're doing, it was doing fine and they decided to change everything, we have to click at least 6 times to open a new tab. who came up with this new feature? that guy must be a genius, definitely deserves a raise, what more will he add? i'm excited for the next updates, i hope they add captchas next

deplorable

The latest update completely renders this extension useless. I can't just hit Control-Period and navigate up and down with my arrow keys to select the container I want. Please revert this change or allow switching back. At least make it possible to use the arrow keys to navigate.
