Tab Groups cannot handle the amount of tabs I have well, it seems

[Kxeon]

I managed to pinpoint the point where started breaking was on July 21. FIle: https://disk.yandex.com/d/dvDx4ap5u1xFtw
Everything before worked fine, but this file and everything after usually fails. I have to try basically everything to get it to work. Seemingly, something that worked yesterday (importing, then terminating pale moon, restarting and it imports correctly) won't work today. (It might work, but it has broken tabs. Presumably because it died again. Most of the time though it doesn't work at all.)
What to do in this case other than resetting? Is it inevitable? Do I have to go back 5 days to be able to keep at least some of my tabs?

Your file doesn't seem to be available. So, how many tabs are we talking about?

[Kxeon]

Your file doesn't seem to be available.

Hmm.. looks like it somehow disappeared into thin air. Or I got the wrong thing.
This one should work, right? https://disk.yandex.com/d/5ifheQEnA4lRXA

Oh, that's not from Tab Groups, but rather from Tab Groups Manager 2? Not sure if I can help with that.
(you may not want to keep the file up publicly, by the way. Likely has personal data in it.)

Dang, I managed to do the same mistake twice.
First I call PasswordSafe pwsafe and now this. Oops.

I just did a test with the exported file, seems to have loaded fine on my system after dropping the extension in a portable. About 1600 tabs?... Not sure if that is considered within normal scope.

Either way seems it needs a bit more info to be able to troubleshoot. You are using a 64-bit Pale moon, I hope?

Yup. Definitely using 64-bit Pale Moon.
By the way, while yes I use AVX2 Pale Moon, at the same time, the bug still happens on normal Pale Moon too so still.

It is very slow to respond with that many loaded so yeah I just think it's beyond the design scope of that extension.

Which Tab Groups Manager are you using? I did enough to get it working on palemoon (Tab groups manager reloaded), but I've no idea what limitations there may be. However, with 1600 tabs, you're keeping the history for all of them. and starting up will take some time as the addon will have to move each tab into the correct group - which will also stress the browser.

There's also some bits and pieces in there that look like it might be keeping two copies of some data, which wouldn't be great on memory usage if so.

It may be possible to rework things to make some of those operations faster and less memory intensive but I haven't been able to spend a great deal of time on it.

You can also check about:memory and learn why actually loading such amount of tabs into Pale Moon is a terrible idea.

[Goodydino]

Why would anyone need to have 1600 tabs? I do not even have that many bookmarks. If one wants to keep track of 1600 pages, why not use bookmarks?

We know that & it's exactly why TGM was so damn good way back in 2009 when it released, it suspended tabs even back THEN, long before ANY of the Browsers added that functionality.
TGM users, especially us older users (used it since release) tend to be power users & were fully aware of those limitations which were much less back in the 32-bit era.
We that still use TGMR, today know the full & extremely convoluted history of this amazing extension, the original developer of TGM (2008) was the very first example of Suspending Tabs AFAIK.

TabGroups Manager by Axel Shootingstar

• TabGroups Manager v2009.03.03.02 Released March 13, 2009 Works with Firefox 3.0 - 3.0.*

• [/b]TabGroups Manager 2011.11.28.1.1-signed.1-signed Released November 28, 2011Works with Firefox 3.6 - 56.*[/b]

Axel Shootingstar was a VERY ACTIVE extension Dev that unexpectedly went silent very soon after that last release ddate, with no notice & plans for improvements, complete silence.
Later research, would only reveal that the author was Japanese (No real name known) & went AWOL sometime after the Fukushima Disaster (March 2011).
It's commonly speculated (Discussions not shown on Classic Archives, so this is from my brains RAM (Human memory is notoriously unreliable & prone to data corruption, so not to be relied on as 100% accurate).
Axel was presumed dead (Unconfirmed), when Mozill switched to "Rapid Version numbering increases", we all just increased the version limit higher with an easy text file edit.

After working flawlessly for so many years, it was Mozilla changing to rapid update cycles, that we worked around by changing the "Upto" version.
Eventually we got a Community Fork with strict ("Just keep keep it working") limits, due to closed source licensing issues.
Users only had access to the released XPI files, & it took years to get even this extremely restricted maintenance release on the Addons site.

Eventually Firefox changes started breaking things & the Revived version appeared.
I actually moved to Pale Moon, when it finally broke, but as I had no issues YET with Firefox, switched back when TGM revived, got TGM working again

• TabGroups Manager revived by miguelromero2000, stilez, tabgroupsmanager, ultrafox

• TabGroups Manager revived 2016.02.03.008 (windows) Released February 3, 2016 180.6 KiB Works with Firefox 3.6 - 46.*

Last version

• TabGroups Manager revived 2017.06.21.011 Works with Firefox 3.6 - 56.*

My permanent transfer to Pale Moon (I'd been on Firefox since I got my 1st PC in 2005), came with Firefox v57
Finally as Firefox killed the old Addons foever, & my second migration to Pale Moon we got the 3rd & ONLY release that still functions even on Pale Moon.
Tab Groups Manager reloaded v1.00 Released Jul 11, 2020

First basilisk/palemoon release
Current release
Tab Groups Manager reloaded v1.01 Released Jul 16, 2020

1st killer features was the ability to suspend Tabs, while they were still available, you could set it up so that only viewed tabs get loaded in the current session.
That's no longer a unique feature, these days though & better ways likely do exist, but that's NOT what keeps me using TGMR even now & TGMR is the ONLY real reason I use Pale Moon at all.
It's the second killer feature THAT I have NEVER seen repeated, TAB GROUPS ARE TABS, we have two Tab bars, top bar is Groups & bottom bar is the TABS inside the ACTIVE group.
With auto hide, & plenty of control over where & how Tabs Work It integrates into Tab Mix Plus seemlessly & despite some minor niggles it's never TGMR causing issues as things changing.

NOTHING matches TGM, or even comes close, never mind improves on it (Believe me, I've tried every single one & nothing comes close to the ease of use that TGM has given me for 14 years.
If I could find another "Tab Grouping manager that used a secondary Tab Bar for grouping (That's Not even possible in "Modern" restrictive browsers AFAIK).
I have no idea how difficult it would be, but I will keep using TGMR & find workarounds, until it stops working forever,

Known Issues that do need some workarounds, seems to be this users issue.
ON Pale Moon launch It no longer auto reloads the last session for me & hasn't done so for years, a very minor niggle, I just need to select the session, from the last of saved sessions.

Most of the issues are again AFAIK, more to do with limitations in saving the data, than core functionality failing.
So given that huge numbers of tabs is sort of the point, the questions a user must ask what do I really need?
It's old written for 32-bit, their are some problematic secondary features, I no longer use.
Hibernate Group, this is useless (Was convenient until it causes the error), if you want to hibernate a group, Bookmark the Group instead. I rarely use Hibernate Any More.
Saved Sessions, these are obviously required, but LIMIT the number, 10 sessions is enough, but have a Manual Backup of your last clean up session *Next point).
Don't get too lazy Use TGMR to get you to a site, save specific pages if you will return, always keep in mind the Database is of limited size, so keep it for Tabs, not huge collections of past data you never actions.
Stop saving Timed backups, or restrict the number saved, those are always a space hog

My entire CPU is using around 3000 MB as I type, Pale Moon is 1% of that Despite my "1000s" of tabs. I only have 4 active right now.
My most excessive RAM usage (I know of because it was recommended to increase Page File to 40 GB) while downloading 1000s of simutaneous mods while extracting & installing (Nexus + Collections, or MO2 + Wabberjack) with many tabs open
Even with that extreme usage, my RAM usage was still under 32BG & I never saw it go over that, My PC DIDN@T access pagefile.

One thing to understand is that "User Support" recommends what makes suoporting users easiest for those providing "User Support", a lowest common denominator method.
Tell everyone they need 40 GB Pagefile, even if that users RAM size negates the need.
I've been hearing "Too many Tabs eat your RAM", for 15 years, because it's lowest common denominator fits all use cases, but that only applies if Tabs are NOT suspended, when they essentially become just Bookmarks.
Not enough RAM can be an issue, but it's not the issue we see when using TGMR, though you get an "Out of Memory error", whicch will cause confusion as here.
In my over 15 years of using the extension, TGM was my chosen tool to mitigate "Too Many Tabs, not enough RAM" NOT cause them, it's always on saving the Database, I get problems, because the database is maxed out, never my RAM.
For the most part All you need is to Stop Hibernating & limit the number saved sessions, but even then it's the backups Database does have a limit, it's that limit that's an issue for me, with over 64 GB of RAM
