Doesn't work at all in new firefox.

This extension takes a snapshot of open tabs every 15 minutes or so for the past 3 hours. If you exit the browser the most recent 10 snapshots are saved, so when you open the browser later, they can be quickly restored. I found this to be very useful.

SHoit

SECOND UPDATE (8 hours later - just burned a day:)

I found the file in the Download Directory. Here is what it looks like:
"C:\Users\USERNAME\Downloads\2023-03-19-T 15 34 02 -0700_ExportTabsURLs.txt"

Search on "ExportTabs" and you should find them all.

Apparently the app is limping along and has been deprecated by ever changing Firefox updates - the last update was in 2020 - and I just didn't notice.

The UI shows outdated files - just 3 out of 74 - and they can be opened but only in the UI, with zero other options like open the folder or copy the location. Nothing.

And since Coder Kevin told us all the files are in App Data/Mozilla/Firefox/Profiles - I believed him. Fool me twice.

Changed my mind - it SUCKS.
5, 2, 1 star.


UPDATE 2023-03-19-Sunday - WAS 5 STARS and VERY IMPRESSIVE.

NOW VERY SUPER DAMN FRUSTRATING, because:

1. I can't find to edit move activate restore or look at the files I am saving.

2. Why would they be buried in a data silo - is that a Firefox GD requirement that is out of your control, Kevin?

3. WHY WOULD YOU DELIBERATELY NOT INCLUDE BASIC FILE CONTROL IN THE APP - Delete, Move, Search -

4. OR EVEN BASIC INFORMATION IN THE APP WHERE THE FILES ARE OR HOW THEY ARE NAMED?

5. My saved files don't appear in the restore tab and can't be found in the system on any drive. The only additional clue to their location, actual name, or extension is a one-line comment by you on this options page somewhere that they are a text file format, saved in the Firefox profile - THAT IS NOT A HELP, KEVIN. IT IS A HALF-CHEWED PIECE OF GUM YOU SPIT OUT.

6. It took an HOUR now going on 2 to resolve this UNSATISFACTORILY -

5. SERIOUSLY - why do I and every Responsible Sigma have to RE-ENGINEER STUFF EVERY TIME WE TRY TO DO SOMETHING A LITTLE ADVANCED? THIS CRAP KEEPS OBSTRUCTING EVERY ONE OF US ALL DAY LONG EVERY DAY -

6. WE MIGHT AS WELL FKG GO TAKE A NAP AND A SHOWER AND WATCH YOUTUBE ALL DAY.

So this is actually a super fail for all your great work Kevin - it's all POINTLESS GARBAGE. Obviously. Such an oversight! (insert a long string of Yiddish explicatives here.)

ORIGINAL 6 months earlier
Works amazingly well, but can't seem to delete duplicate saves (which is easy to do.) Should be a delete function on the import / load session screen. I'm still a novice at it but this kind of issue is not encouraging.

Cool raw export. An option without favicon should be awsome (:

Works exactly as it says for us "tab hoarders"
Thank you Kevin

After trying several add-ons over the years to backup tabs for the occasional (but inevitable) loss of all tabs, this one is the only one that worked and recover all my tabs flawlessly. Many thanks to the developer(s).

Loss of tabs seems to happen for me when clearing all history manually and closing FF right after. Sessionstore backup is gone the moment you reopen FF and discover your tabs are gone.

This add-on might not work for every crash, but it works for this one, which I have once or twice a year.

For worse situations (I never had a corrupt FF folder), I resort to ~monthly manual backups of the FF folder - you just wouldn't recover your most recent tabs.

Suggestion : the choice offered between 1) replace all current tabs by the backup or 2) open the backup session tabs in a new window is really great and well thought !
A convenient 3rd option would be to add the tabs to the current window instead of a to a new window (yet hardly a must have).

I've just tried "REPLACE existing session" feature - it looks like it just closes the current session and nothing else. "ADD ..." feature works properly. By the way where are the autobackup files located in FS?

Great for me, it does the job.

One comment thought, I think the datetime format used for the filename should be :
2021-01-31T14:00:00+01:00
and not :
2021-01-31-T 14 00 00 +0100

see https://en.wikipedia.org/wiki/ISO_8601
Thanks again anyway

Edit : actually I realise, you cannot have colon (:) inside a filename on Windows, which is a shame, because it's perfectly fine with Linux
But then you could follow the basic (compact) format, also allowed by the ISO standard, which is :
20210131T140000+0100
but it's less easy to read

Cheers

Overrated dysfunctional, unreliable, (just lost all tabs from previous session) illogical and non intuitive but archaic.

The ONLY Firefox Tabs Exporter I could find that keeps the tabs separated into window groups in the export file. Every other Add-on exports as one single list, which often loses a lot of context.
