The first extension/add-on that I always install for Firefox is Tab Mix Plus. This Firefox extension allows me to switch between my current tab and a recent tab without “scrolling” through every tab.
For example, if I have 6 tabs open and I’m currently viewing Tab 3, I can hold down Ctrl and hit the Tab key to go to the tab 5 (and release.) To go back to Tab 3, I simply need to quickly hit “ctrl+tab” in one swift move and I’m back on Tab 3.
Recently, it stopped working and would just cycle through each tab in chronological order. Furthermore, I could not view the options menu for Tab Mix Plus. After much googling, I found the culprit:
Tab Mix Plus does not play well with the recent Skype add-on for Firefox. Therefore, to continue using Tab Mix Plus you will need to discontinue use of the Skype For Firefox add-on.
