Hi Folks All of a sudden, Firefox started opening multiple windows when I try to open new tab. Even after quitting--when first opening--multiple windows appear! Help

is this when you are trying to open a blank page or when selecting a link?
Start Firefox in Safe Mode {web link}
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
You can check for problems with the sessionstore.jsonlz4 file in the Firefox profile folder that stores session data.
- rename/remove sessionstore.jsonlz4 and sessionstore.js
You may also have to rename the sessionstore-backups folder.
When sessionstore.jsonlz4 is deleted you lose pinned-tabs and open tabs and you will have to recreate them, so if necessary make a note or bookmark them. sessionstore.jsonlz4 is only present in the Firefox profile folder when Firefox is closed.
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
- Help -> Troubleshooting Information -> Profile Folder/Directory:
Windows: Open Folder; Linux: Open Directory; Mac: Show in Finder - https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data
You can check the homepage setting.
- Options/Preferences -> Home
- https://support.mozilla.org/en-US/kb/how-to-set-the-home-page
Firefox supports multiple homepages separated by '|' (pipe) symbols.
You can create a new profile as a quick test to see if your current profile is causing the problem.
See "Creating a profile":
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
