TO THE DEVELOPER, THERE IS A BUG.
---16/11/2025. A BIG BUG is that, if I want to find a tab that is opened, I use this addon, find it and I select it and I right-click to use the option "Open in a new tab", it gives you for example that:
moz-extension://b0908c4d-f773-4592-8ec9-fc00307717cc/561
so it does not open it in a new tab using the URL of the tab, it seems to lead to a filename and you cannot access at all this tab this way!!!
Therefore, I do not get at all the tab I wanted to open on a new page even though it is available and open in my sea of tabs!!!

---When you have 914 tabs, among them pinned tabs, it shows the number 100 on the icon that represents this addon instead of 914. That ought to be a bug.
---When you have more than 1000 tabs, it shows 109 instead 1009.
---When it reaches 1,000 or more tabs, you could put instead >1k.

Very useful when you have many tabs open at each Firefox session like I do.
Thanks to the developer.
