My expertise (more than 30 years) is in UNIX, shell scripting and perl scripting. NOTE: I am not a java or javascript programmer. Google searches on jsonlz4 and also failed to turn up any useful information.Īny help in decoding the jsonlz4 bookmark file, or perhaps extracting bookmarks from the places.sqlite file would be appreciated. Attempts to remove that header and then run the file through lz4 have also failed. The new format is suposed to be based on the very fast lz4 compression, but I have been unable to find information on exactly how it is compressed, or better still how I can decode and extract the bookmarks (outside firefox).Īttempting to simple run the files thru 'lz4' does not work as the files have a different header (file magic, and what I believe is a checksum hash). Now firefox started to compress the json file to a jsonlz4 format, and of course my bookmark extraction scripts no longer work.

More importantally this can be done automatically without manual exporting, overnight, and without requiring firefox running! Generally because I am logged out. I used the bookmarkbackup for a number of reasons.ġ/ it was statis and would not chnage halfway throughĢ/ it was a lot easier to parse json tahn trying to extract sqlite records.ģ/ it was clear text, so it was easy to see what was going on and fix/tweek things as needed. If it does not, press the Alt-key on your keyboard and select History > Restore Previous Session.For years I have been automatically parsing the latest 'json' bookmark backup file to generate a 'hotlist' of my bookmarks so I can access them from anywhere in the world, or refer people to them.

Firefox might pick up the session automatically.

Paste the copied file to the root folder.

Go back to the root directory of the Firefox profile.

Copy the session restore backup that you want to restore, e.g.

Rename recovery.backlz4 to recovery-backup.backlz4.

Rename recovery.jsonlz4 to recovery-backup.jsonlz4.

Open the sessionstore-backups folder of the profile.

Open the profile folder and rename the current session file sessionstore.jsonlz4 to sessionstore-backup.jsonlz4.

Make sure no instance of the browser is running.

I'm pasting the right procedure here for future reference, but all credits go to Martin Brinkmann from Ghacks: How to restore Firefox sessions if Session Restore is not working correctly: Sorry for the late response, I just faced the same problem with Firefox 78: I closed firefox window by mistake while it was still starting up, and all my 200+ opened tabs were gone :( The previous previous session of 200 tabs of webpages were also created by clicking History->Restore Previous Session, and Firefox doesn't actually open all the 200 webpages when I restored it, but open each webpage when I actually click its tab, and I didn't click all of the 200 tabs. Note that it seems to me difficult to find out the previous previous 200 webpages' URLs from most recent history in Firefox.

Is there some way to restore the previous previous session of 200 tabs of webpages? Now clicking History->Restore Previous Session only restore the single tab of webpage. But instead of doing that, I clicked a new tab and opened a newpage, and closed the tab, which closed Firefox out of my expectation (in Chrome browser, closing the only tab doesn't close the Chrome browser). When I started Firefox again, I had a chance to restore the previous 200 tabs of webpages, by clicking History->Restore Previous Session. I closed Firefox, and then rebooted Ubuntu. I opened about 200 tabs of webpages in Firefox 59.0.2 (64-bit) on Ubuntu 16.04.
