请求更新地址栏显示为 Mozilla 页面时提供的 Firefox Browser 图标为新版图标或更改为 Firefox 图标。

This FoxyTab addon could show country or region flag accroding to IP address, and if the current address is some types of special address like any addons' setting page, this addon shows a Firefox Browser icon, but the version of the icon isn't lastest.

Awesome add-on - exactly what I was looking for!

Great add-on! After reinstalling add-on works fine.

I run Windows Task Manager all the time (to guide me in maintaining RAM usage below 80%). I tend to have 4-10 Firefox windows open; if careless, I allow enough open tabs (e.g., RAM usage) to slow or crash FireFox/Windows.
The ability to quickly save (~all tabs) and CLOSE a Firefox window, helps me avoid Firefox/Windows crashes.
On 6/24/2020, I discovered FoxyTab, which
allows me to quickly copy almost all
URLs (in the "current" window of FireFox)
to the clipboard, and then paste them into a file (to save "where I'm at" in the Firefox window). (Optionally, I usually include Webpage-Title for each tab.)
With FoxyTab, I can even do this fairly quickly for ALL my Firefox windows.
Afterward, I can winnow/add-to/rearrange the "tabs" within that file.
FoxyLink AddOn allows me to later restore (~all) those tabs within a Firefox window,
often after (to free-up RAM) I reboot FireFox and/or Windows.
I have found both FoxyTab and FoxyLink to be highly reliable, and reasonably straightforward to use, though I often have to review FoxyLink usage instructions; the two AddOns have slightly different orientations.
