I am in Private window with firefox even though it does not say that when I click to open a new tab. But my firefox crashed today and it did not remember my tabs. Why not?

When using Private Windows, nothing is recorded. Including history.


In the address bar, type about:crashes<enter>. Note: If any reports do not have BP- in front of the numbers/letters, click it to submit them.

The crash report is several pages of data. We need the report numbers to see the whole report.

Using your mouse, mark the most recent 7 - 10 Submitted crash reports, and copy them. Now go to the reply box and paste them in.

Please, Do not post a screenshot ! !

I thought it does save it and when you Close Firefox then it deletes everything? And that's something you can tell them that would be good in the next up date is to have it remember history and tabs when in private window and when I Close it, then it erases everything. Thank you for answering my post. God Bless

If you use PM mode then session data is kept in memory and is never saved to the profile file. That is how PB mode works and this will never change, so you won't be able to restore a PB mode session on the next start. You would have to bookmark all open tabs before closing Firefox. That is the risk you take when you use PB mode and Firefox crashes and you lose all your tabs.

If you have submitted crash reports, please post the IDs of one or more recent crash reports that start with "bp-".

  • bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
