After a period of time the tab bar stops scrolling or scrolls eratically, the first and last tabs are inaccessible via the mouse
Over the period of a day or three the tab bar stops responding to attempts to scroll the tab bar. I can still advance through the tabs with ctrl-tab and shift-ctrl-tab but the tab scroll arrows either don't work at all or work erratically.

Start Firefox in Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.

I tried this but no luck. Even in safe mode it still occurs. Often takes 24-36 hours or more before it shows up.
Does it help if you close and restart Firefox to get the normal behavior back?
Yes, if I bookmark all my tabs and restart Firefox then things work again. I have many tabs open in my daily work and it's a nuisance to have to bookmark them all and then exit and restart FF.
Session Restore should be able to restore the tabs automatically.
- Tools > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"
A "solution" that requires restarting the program is not a solution at all. This is a bug in Firefox - once you have enough tabs open, tab scrolling becomes unresponsive, and tabs at the far right and left cannot be tabbed to at all. It is also not a solution to open less tabs; if I want 50 tabs open, and work best that way, then FF should permit that. It does not do so now.
Thanks.
