(First off; I have not changed any settings related to history in firefox, nor is firefox configured to delete history, nor am I in private mode) For all purposes, all the history is set to be remembered and saved. (I am also the sole user of this computer) Started having this problem this last weekend (Around June the 6th 2020) At first I didn't notice but after a while large portions (hours worth) of my history were missing. The problem seems may have gotten worse , more and more seems to vanish. To be specific seemingly randomized pages fail to register in the history. I have attempted verifying the integrity of places.sqlite (is this even history?) ''as was mentioned on another similar support report (about history not recording everything)'' but as soon as I pressed verify the log showed the following - > Task: checkIntegrity - Unable to check places.sqlite integrity: Error: Error(s) encountered during statement execution: > Task: invalidateCaches - The task queue was cleared by an error in another task. > Task: checkCoherence - The task queue was cleared by an error in another task. > Task: expire - The task queue was cleared by an error in another task. > Task: originFrecencyStats - The task queue was cleared by an error in another task. > Task: vacuum - The task queue was cleared by an error in another task. > Task: stats - The task queue was cleared by an error in another task. > Task: _refreshUI - The task queue was cleared by an error in another task. Can I repair my current places.sqlite (Bookmarks / History?) ? Do I have to delete it/other places.sqlite files so firefox can regenerate? I have a lot of bookmarks, is there such a thing as too many?
