Recently rank checker started hanging on some search queries & the button on the SEO Toolbar which launched rank checker stopped working. Both of these issues should now be fixed if you update your Firefox extensions.
If ever the toolbar button doesn’t work one can enable the Menu bar in Firefox, then go under the tools menu to the rank checker section to open it.
Years ago we created a new logo for rank checker which we finally got around to changing it today.
