---1ST ISSUE) I would like to right-click on a listed tab and have the option Open to open this chosen tab at the right of my current tab.

Sometimes, **you simply want to open a second time at the right of your tab a tab that is already opened somewhere else but that is very far from where your current tab is because you have many tabs opened.** I regularly have at least 700 tabs opened on a regular basis and sometimes near 1000.
Such a far away tab, as it is too far from where you are, you would like to be able to have it opened a second time but just right to where your current tab is.
**It is sometimes very hard to find your way back to your current tab when you have many tabs and the tab you look for is very far from your current tab!**

---2ND ISSUE) **Allow the size of the window when you click on the TabFind icon to be resize at will.** The reason being that the current size does not show sometimes enough of the name of the tab to be able to clearly figure out that it is the one you want and not a mistake.

Many thanks to the developer for this firefox addon.

only running at current windows, not all windows

Promising. Unfortunately currently only searches in the current window (I have more open FF instances with many tabs open in all) and I haven't found a setting to change it.
