First thing is when I launch Firefox, the application runs, and is shown in the Task Manager process list, but no browser window appears and it is not listed in the running application list in Task Manager. If I quit the application process and relaunch Firefox, the browser starts fine. Is there a way to fix this?
My other issues are, as I said, with add-ons. If this isn't the correct place to ask about those, could you please direct me in the right direction? The first, and smaller problem, is with Duplicate Tab. Usually, I can right-click a tab and duplicate it in the same window and other nifty things, but recently that option hasn't been appearing when I right-click.
My other issues are with Session Manager. I have tried disabling then re-enabling it, uninstalling it and reinstalling it, but neither have fixed these issues. Firstly, normally there is a sub menu under Tools that says Session Manager, and allows me to save, restore, and so on, my sessions. But now that menu doesn't appear at all.
The other issue with Session Manager is that I can configure it via the Add-ons sub menu to start up each time Firefox starts. Only, sometimes it does, and sometimes it doesn't. And even if it does start up when Firefox is launched, it doesn't load the selected session.
I've been considering uninstalling Firefox and reverting to an earlier version of the program, but I don't want to lose my bookmarks, saved passwords, saved sessions, etc.
