Cannot disable Container Tabs

[concatime]

Description

When using CanvasBlocker with Firefox Developer Edition (69.0b1 on Arch), I simply cannot disable Container Tabs, which seems to be a hard dependency of CanvasBlocker.

Response from email:

CanvasBlocker does not use container tabs but supports them. If you do
not use it in Firefox CanvasBlocker will just work fine.

Expected Behavior

Being able to disable Container Tabs.

Current Behavior

Option grayed out.

Possible Solution

?

Steps to Reproduce (for bugs)

1. Get Firefox Developer Edition (69.0b1 on Arch)
2. Install CanvasBlocker
3. Try to disable Container Tabs

Your Environment

• CanvasBlocker Version used: Version 0.5.12
• Firefox version incl. 32- or 64-bit: Firefox Developer Edition 64-bit (69.0b1 on Arch)
• Operating System and version (desktop or mobile): Arch Linux

Interesting point but unfortunately there is nothing I can do. I have to use this API to support the people who use this feature (#350 and #368). We would have to open a change request at Mozilla to allow extension to use this feature and let the user disable it.

PS: this feature should be also available in Firefox 67.

What are the down sides of having this setting on? Would these go away if you just delete all available containers?

When you right click on a link, there is an annoying “Open Link in New Container Tab”, which on its own has a sub-menu with Personal, Work, Banking & Shopping. Quite annoying. For now, I will use this hack until this get resolved (if…).

These are the Bugzilla tickets concerning this issue:

https://bugzilla.mozilla.org/show_bug.cgi?id=1386673
https://bugzilla.mozilla.org/show_bug.cgi?id=1458585

Someone made a patch 7 months ago, but nothing happened since then for no apparent reason. Maybe @kkapsner can poke the right people there or take matters into his own hands, to speed up the process. 😅 I've upvoted the tickets ages ago, since I've been 'suffering' from this issue when Cookie AutoDelete introduced Container support..

@concatime Thanks for the hint of the userChrome.css entry, haven't thought about the ability to hide that annoying context menu option that way before.

I will gladly make this permission optional.

An extension, CanvasBlocker, requires Container Tabs.

I have them Enabled as other extensions want them (Facebook Container for example)
When I Disable any of them I still see the same message until all are Disabled.
Still a Firefox bug?

[kkapsner]

Yes

[alekksander]

is this still a thing in 2022? it seems so, as i can't disable containers without disabling this ext. first.

[kkapsner]

Firefox did not change in that point - so the situation did not change.

To anyone with the issue, please just use the userchrome.css code linked by concatime.

Can confirm it works in May 2023 on Firefox 111 - the context menu item disappears, so will not be seen when right-clicking things. It's the best we can get, I believe, but it's good enough for me.

I still see this in 2023 FireFox 117 ... what is the fix? I don't have any Container addons installed.

2022 年這還會發生嗎？看起來是這樣，因為如果不停用這個擴展，我就無法停用容器。 ...

It’s 2025 year ...

This problem is still ...
