Often when Firefox is closed and reopened ALL the tabs and tab groups are missising. FIX!!!!

Posted

For reasons that are unclear to me I sometimes close Firefox and later re-open it. In some cases ALL the tabs and tab groups are gone. Today it opened in MSN.com and ALL tabs were gone. I put a lot of pages on these and have NO WAY to find them all again. If this continues and you cannot give me a way to recall them I simply will have to go to another browser. It always happens when I need them most and don't have time to even track down one. It completely upsets my day, week, month whatever!!!.

Is there a way to get them back? Someone asked a similar question and was never given a useful answer.

Make sure you have "Show my windows and tabs from last time" selected in your Startup preferences?

Make sure that Firefox closes properly and that there isn't a hanging Firefox or plugin-container process left in the task manager.

Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.


App (pinned) tabs and Tab Groups (Panorama) are stored as part of the session data in the sessionstore.js file in the Firefox profile folder.

Make sure that you do not use "Clear Recent History" to clear the "Browsing History" when Firefox is closed because that prevails and prevents Firefox from opening tabs from the previous session.

Question owner

These instructions have been reiterated for everyone with a question related to losing tabs. Mostly they address how to prevent it. My settings etc are correct and do not change randomly to produce the effect in the complaint. The one thing I do no do regularly is close Firefox from the "file" button. Why this is important only on occasion escapes me but I can do that.

When Firefox is restarted it often is taken over by MSN and there is no access to restore previous session. Therefore, it becomes the previous session and useless.

Apparently there is no process that allows one to re-establish the tabs when Firefox comes back with no command line with "File" etc on it. Why it happens in the first place is unclear. However, if one has many tabs it is a disaster. I could, of course, make bookmarks which I do but keeping those current is nearly impossible.

I've begun having this problem as well. Reviewing the above, I seen no errors that I' making. A few weeks ago, without being aware of an update to Firefox, it began behaving differently than it has for years. I've always had it set to open to an empty tab, now it often opens to the 'Firefox Home Page' (which I've never used)... this despite resetting my opening page to "Show my windows and tabs from last time" (upon troubleshooting the 'home page issue' I found that the opening page had reset to FF Home somehow. I store a lot of pages in tab groups and having them disappear is a major bummer since they're news articles I'm waiting to copy.

Also... I run CCleaner weekly and I know that will erase the group tabs I've stored so before running it I have to store those URL's another way. Does anyone know what I can uncheck in CCleaner to keep those tabs?

Thanks.
