Useless. Does not integrate into the tools menu and therefore you have no access to anything within this add-on.

If you want to copy something that you wouldn't normally want to, this is the extension for you.
WebExtensionAPI has pretty much sent everything else down the loo.

Is there no way to show the profile name in the titlebar???

I used this one for "force addon compatibility". Missing greatly.

I like it, I still miss the "open bookmark in new tab"

How can i use "Force Addon Compatibility"...

Sadly it doesn't work anymore to force addons compatibility =(

I'll use this occasionally with Waterfox.

More generally – for any Firefox-like browser – identifying extensions primarily by name is troublesome. Because addons.mozilla.org (AMO) too often makes it unnecessarily difficult to find by name; because developers too often use multiple names for a single product; and so on – so I can't give five stars.

The extension could be improved by more positively identifying extensions. Include:

- either the AMO address of the extension, non-localised, for example https://addons.mozilla.org/addon/nightly-tester-tools/
- or (if not listed on AMO) ideally the support URL, less ideally the home URL.

If no URLs is associated with the extension, be explicit about the absence of a support URL.
