My homepage tabs (12 webpages that used to load as specified under "Options" "General") Stopped Working

My tabs (all the pages I want to see every day when I start Firefox) were no longer loading after my last upgrade of Firefox. The system was loading the last browser selections open at the time the program was shut down. If there was a SINGLE tab on the last active browser, that tab and only that tab was loading when I re-opened Firefox.

SOLUTION FOR ME WAS: 1. Generate the string of tabs you want by opening them in a single browser. 2. Go to Options -> General (access via the top right triple bar symbol just below the + sign). 3. Select "When Firefox Starts" "Show My Homepage." 4. Click "Use Current Pages." 5. Save a copy of the list of pages that is generated in step 4 (i.e. save code from step 4; it is the list of pages you want to start when you open Firefox) in Windows Notepad or equivalent. 6. Enter just "about:config" (no quotes) in the browser address bar at the top. 7. Ignore "This may void your warranty" and click on "I'll Be Careful..." 8. Click on "browser.startup.homepage" on the list and Right Click the line and select "Modify." 9. Enter the code you copied in step 5 and put it in the space provided. 10. Click "OK." 11. Close the browser after closing a few of your selected pages for startup and be sure that when it reloads, you see the entire set, including the pages you closed just prior to closing the browser.

I have not tried to do this with two open Firefox browsers. It WAS previously possible for me to open up multiple browser sets by simply opening Firefox. I'll test that after publishing this solution. (IF it was in fact here already, I could not easily find it.)

MY QUESTION: If you know the code for opening up multiple Firefox browsers on start-up of Firefox, could you please supply that below? Thanks.

I wasted a lot of time checking all the other things people had listed such as malware etc. etc., so I hope this saves someone some time!  ;)

To have more than one tab, use the | on my keyboard; Shift \ Place it between the individual web pages.

Yes, those symbols are automatically generated in the sequenced solution I posted above. That was not the question. It may not be possible, but I wanted to be able to open multiple browsers upon startup.

There is a command-line switch to start up an independent instance of Firefox. For best results, create a second profile and point it at that profile, otherwise, there may be a conflict.

See -no-remote in this article: https://developer.mozilla.org/docs/Mozilla/Command_Line_Options

Or did you mean that you want to open multiple windows in a single instance of Firefox?

No, that problem was solved in the solution I listed in my first post. Thanks for the other info and the quick response. It may be simpler just to drag pages off a main start-up page than to log into multiple accounts.

This is from that page you cited:

"Open new instance, not a new window in running instance, which allows multiple copies of application to be open at a time.

firefox -new-instance -P "Another Profile"

Note: Not available for Windows, see bug 855899."

...not available in Windows it says.

You can check if you have a user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.

You can use this button to go to the current Firefox profile folder:

Good point. I should have mentioned that I found that file in about:config (see above instructions) and toggled it to "false." When it's set to true, it gives you the LAST configuration of the LAST browser that was being used prior to closing all Firefox browsers.

You need to remove the user.js file or at least remove the line from user.js if you have created the file yourself and want to keep it.

The browser.sessionstore.resume_session_once pref is used when you need to restart Firefox for instance if you install an add-on or apply an update. In such a case you will want to preserve the tabs that are open and setting this pref to false will prevent this and you lose open tabs.

I did remove that user.js file as well to be complete. But toggling that .resume_session_once preference to true actually forces the browser to open the last saved set of tabs rather than the set I want.

The file to be removed is located here in Windows 10: C:\Users\YOUR USER NAME\AppData\Roaming\Mozilla\Firefox\Profiles\rona4gb8.default

Is that "rona....default" file named after a user who works on Firefox? Not my username but it is stored under my USER NAME where noted in the file path shown above.

Firefox uses a random name for the actual profile folder and in your case has come up with rona4gb8.default, so that is OK and no reason for concern. There appears to be software that creates a user.js file with the browser.sessionstore.resume_session_once pref set to true for some unknown reason as we see this issue regularly reported. The original time stamp of the user.js file might have given a clue when this has happened.
