Restore tabs
After the most recent "upgrade", I cannot access my old tabs and there is no restore previous session option under history, plus everything is exceedingly slow. How do I contact a staff member? What is a telephone number for support?

Hi, there is no official phone support.
As a preliminary question, do you use Webroot security software? There is a known conflict; I'll list a workaround below the line if relevant.
Did you lose any data besides open tabs -- bookmarks, history, add-ons?
Did your Firefox perform a "Refresh"? The tell-tale sign is a new "Old Firefox Data" folder on your Windows desktop. If you have that, hang onto it for data recovery purposes.
If you have Windows 10 or 11, and Webroot security software, and 64-bit Firefox 97, there is an incompatibility which cripples Firefox.
People are working with Webroot to issue an update.
If you do not run Webroot security software, please ignore the rest of this.
A couple users confirmed that uninstalling and reinstalling WebRoot resolved the issue.
If you can't do that or it doesn't work, several other users confirmed that one temporary workaround is to run Firefox 97 in backwards compatibility mode. Here is how you would set that up:
(1) Open the Properties dialog for your Firefox shortcut. Either:
- right-click a Desktop shortcut, then click Properties
- right-click a pinned Taskbar icon, then right-click the Firefox (or Mozilla Firefox) item, then click Properties
(2) Switch to the Compatibility tab
(3) Check the box for "Run this program in compatibility mode for"
(4) If the selector for that option is not set on Windows 8, switch it to Windows 8
(5) Click OK and then start Firefox (if Firefox won't start because it is already running, you might need to restart Windows)
As a result of this change, you may notice that some Windows 10-specific features and styling are disabled. However, I am not aware of any major changes. If you experiment with this, let us know your experience.

Thank you very much! Webroot was the problem.
