Addon Update Checker
I didn't like Firefox updating my add-ons without my knowledge, so I turned off add-on updates, but I still wanted to be notified of new versions. So I wrote this extension. Things to know: if you change options while in the checking or found update states, the icon will be grey until the next check/restart.
Sidebar Auto Show/Hide
This is as a working version of the part of Optimoz Tweaks that I used. The sidebar auto open and close when the mouse touches the left side of the browser window. I rewrote the preference page to be inline and the way the preferences are read/written by the extension. I removed 'eval's and 'setTimeout's that generally aren't allowed in extensions for security reasons. I wrapped the everything in the extension in a variable and rewrote the way many functions are called (so they could be wrapped.) I eliminated several functions that were only called once or twice and were only one or two lines long. Replaces all 'var's with 'let's. I fixed the hand icon that can hold the sidebar open regardless of mouse position. Probably more too, but that's all I can remember. This extension does constantly check mouse position which can theoretically be a performance hit. I've never even seen 1% CPU usage when moving the mouse though.
Hide Tab Bar With One Tab
Hide the tab bar if there is only one tab.
Toggle Link Visited Status
Adds a right-click menu item to either mark a link visited or unvisited depending on its current state using the async history service needed by Firefox 23 and above.
All Tabs Restorer
Brings back All Tabs shortcut page by pressing Ctrl+Shift+Tab or clicking optional toolbar button (drag from customize window.)
This started off as Dao Gottwald's Crtl-Tab (https://addons.mozilla.org/en-US/firefox/addon/ctrl-tab) version 0.19, the last version I could find that had complete All Tabs code. I removed all of the Crtl-Tab code and fixed any problems I could find in the remaining All Tabs code by renaming functions and grabbing needed functions from the removed Ctrl-Tab code, removing left over Firefox code from the hatchet job they did of removing their All Tabs code,
Hidden options to change hot keys if the default doesn't work for you:
extensions.allTabsRestorer.keyCode - set to key or key code (like Z)
extensions.allTabsRestorer.keyModifiers - special keys needed to launch (like ctrl, alt)
Restart Firefox after making the change.
