Serious bugs in the Facebook-container extension code involving triggering actions on URL change / container change.
WHEN USING MULTIPLE CONTAINER ADD-ONS
- Clicking links / changing URLs in omni-box from container site to container site will close the current tab (history lost) and opens two tabs to new container site
- Clicking links container site to non- container site working okay (one new tab opened, history container maintained)
- For Google container add-on sometimes when clicking on link in search results, it will not open a new tab but opens a new site in the current container (login session lost). This means Google is not separated from other sites. Also occurs when typing in the omni-box
- Changing URLs in omni-box from container site to non- container (and visa versa) will close current tab (it should open a new tab instead of closing the container tab although arguable)
- No problems while staying in same container
*** TESTED ***
All container add-ons are conflicting as a result (you can only use one). Mozilla needs to change the code that triggers actions (triggered twice going from container to container site using multiple add-ons).
Conclusion: You cannot fork the Facebook container add-on without rewriting the code.

Is Tumblr Container Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Tumblr Container requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
Risk impact analysis details
- Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
Tumblr Container is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
Risk likelihood analysis details
- High This extension has low user count. Unpopular extensions may not be stable or safe.
