I Love "All Tabs Helper". I've been using it for years. I can't browse the web without this Addon. I am a Firefox user mostly (I Love Firefox, than any other browser). Sometimes I use Chrome too. Which I have installed an almost similar extension/Addon in Chrome named "Tab menu".
But in Firefox this Addon does much more than its similar one in Chrome.
You have also Fixed a bug which showed HTML entities in menu item titles, on your recent Update. That's great!
Only one small notice... If Icons were a little Bigger in the panel would be perfect. (Not the text, just the icons of the webpages).
Excellent Job guys!! Thank you. :-)
