Using FF 20.0.1 All of a sudden, today/yesterday, when I reopen FF, the tabs that were there when I closed are not there anymore----the only tab open is my homepage......

Yes, I do have "show my tabs from last time when I open FF" checked.

What's up?? Is this because they updated FF to 20.0.1??

If you go to the History menu, can you Restore Previous Session? If that's grayed out, there was a problem accessing your previous session data.

Is it possible that you are starting your Firefox session in permanent/automatic private browsing mode? This article describes how that gets enabled: Private Browsing - Use Firefox without saving history (it involves setting Firefox not to remember any history).

No, "restore previous session" is greyed out---not using private browsing


One thing I do remember from few days/week ago, last I checked anyway, I did have FF 19.0.1, and today when I'm having problems I checked and I have 20.0.0---seems they automatically updated me, and now I have a problem.

Is this connected, and how to fix??

In case you are using "Clear history when Firefox closes":

  • do not clear Browsing History

Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, and passwords.

I am NOT using clear browsing history! I have it set to open previous tabs and keep my history.......

All my settings are set that I should be keeping my tabs----the only thing that has changed is the FF update.....???

Does Firefox create a sessionstore.js file in the Firefox profile folder?

Is Session Restore enabled and working?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

Some of this is a bit technical for for, bit I got the main idea and gave me something to think about...thank you.....I did fix it on my own by uninstalling FF then reinstalling again.....I put in a few tabs and they came back up when re-opened..... One thing I did notice had to do with them automatically updating me to 20.0.1---- (this is where I think there was the error within FF)----- After reinstalling, I had to set my appearance again----I went to appearance and noticed "default 19.0.1" was disabled as being "incompatible with 20.0.1"-----so I picked another theme, just so happens it was the theme I had before, and it's working again (have no idea what the default for 19.0.1 was that wasn't working?).... Seems like something went wrong when I was automatically updated with the default theme?? Sounds kinda weird to me.....

Now, the only problem I'm having is when I click on Tools--addons or extentions---nothing comes up to see-------when I click on addons, there is a swirling circle that keeps on swirling, page never seems to come up, and on extentions---it's a blank page......I have the Amazon Wish List, Read later, social fixer and couple of others----shouldn't they be showing somewhere are having been installed?? I thought they used to show up??

Did you reset Firefox?

If you reset Firefox then a new profile is created and some of your data (bookmarks, history, cookies, passwords, form data) is automatically imported and your current profile will be moved to the desktop (Old Firefox Data).
You will lose extensions and other customizations (toolbars, prefs) that you've made.

It is possible to recover more data from the old profile, but be cautious to avoid carrying over the problem.

I didn't know about "resetting" FF, I only manually went to installed programs and uninstalled, then found FF and downloaded again.....is there a difference in this and what I did?? Benefit of one over the other?
