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.

Is "disable addon compatibility checking" feature still there? Can't find it anymore.

Please do not ONLY use WebExtensions, read this:

and make Pale Moon work again.

@ Henriik
I understand your sensitivity to my recent review in which (among other things) I congratulated you on keeping Nightly afloat.
I cannot, in all honesty, change my "star rating" because, whosoever's fault it is, Nightly is a shadow of it's former self.
Sadly, I do not have the skills required to help. This makes me sad.

Why we skip support from Web Extension version of the add on for 55 version of Firefox?

The user who wrote the reviews as IMHO an idiot (almost!). The developer took his time and gave a considered reply Solving the reviewers problems. And why I am writing this is becasue he did not even have the manners to thank for the reponse. I hope most things get screwed up for him/her. We need better standards on the web. Feel free to repond to me offline. Dont know if poss from this site.

"Use comma between entries when copying the list of extensions (#195)"

You just screwed this up big time. Without the commas, I could add the list of extensions into an Excel spreadsheet. I used the spreadsheet to compare my various profiles across my computers.

Now, because you made this change after all the YEARS that NTT has been around, I now have to work around this if I am going to maintain my spreadsheet.

I’m guessing you never stopped to consider how this change was going to affect those of us who have been using NTT all these years before acting on it. Thanks a lot.

Reply: Incorrect! All I needed to do prior to this change was Ctrl+V to paste the list of extensions into Excel.

I do not import which is what you are talking about. I pasted. I can't do that now because the entire list goes in one (1) cell rendering things worthless.

Again, you failed to consider the unintended consequences of this change before making it.

Leider funktioniert dieses bisher sehr gute AddOn ab Firefox V. 48.x nicht mehr!
Ursache ist die Modifizierung von Firefox betreffend Richtlinien in Sachen AddOns.

Abhilfe gibt es keine, außer sich nach aktuellen oder ähnlichen AddOns umzusehen, welche man nicht mittels
"Nightly Tester Tools" freischalten muß.
Man kann somit getrost unter Firefox 48.x "Nightly Tester Tools" deaktivieren, oder gleich deinstallieren.

The option to disable addon compatibility checking does not work in Firefox 48.

Good way to force the installation of incompatible extensions.
