bug returning from hibernation: open firefox is ignored

In case anyone's interested, under Debian 12, when I resume from hibernation, if I have Firefox running as well as Tbird, if I click on a link in an email, the existing instance of Firefox is ignored and a new instance is opened. The first instance is in fact frozen -- it looks as it should but trying to change tabs or open a new tab is inactive. Seems I have to kill the open instance of FF, then if I click on a link in an email, FF pops up as it should with a new tab for the link, but the existing tabs are all there and all functional. It feels like a bug -- Tbird seems not to know that FF is already running.

I hibernate every day and usually have Nightly, current Firefox, and Waterfox open with no issues. ... Memory: 62.1 GiB of RAM

It shouldn't be an issue if you have a lot of free RAM available.

It is not possible to launch two instances of the same profile, external links may open in a new window depending on the request and browser configuration. Try changing browser.link.open_newwindow.override.external to 3 in about:config.

Does the freeze still happen if you disable hardware acceleration?

Resuming from hibernation on Linux has historically had performance issues and is disabled by default on major distros like Ubuntu.

I never got hibernation to work at all until Debian 12. But the above is the only problem I've detected so far. Of course I can't say where the issue lies, could be Debian itself, but it smells like Tbird simply doesn't know that FF is already running. Dunno, maybe that's Debian's job or maybe Tbird could simply 'check'? Perhaps, as you say, hibernation has been so unreliable that this issue simply hasn't come up very much.

I hibernate every day and usually have Nightly, current Firefox, and Waterfox open with a few issues. see screenshot You should try the same steps on a different distro and the hardware, drivers, or kernel could also be an issue. Try downloading Firefox from Mozilla. Download, unzip, and run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

Yeah, I guess the problem could be in any number of places. FF here is ver. 115.9. Mind ... if I had to guess I'd say it was Tbird, since FF by itself shows no problems, it's only when Tbird tries to open a link that the 2nd copy of FF is started. Maybe I'll do as you say and grab the latest version from Mozilla directly. Tx.

Just after saying that, I switch to 445 G9 and it was hibernating, but 2 times in a row network would not work. Had to restart and all is well.  ;-)) More ram and swap help, but i still have the occasional waking up problem, but the issues are more on the OS and hardware and rarely Firefox.

Ooops ... nope not fixed. I did a hibernate and resume last night and it seemed fine. But that was probably just the Quantum Observer Effect -- I was watching so it didn't misbehave. But this morning, it's back to ignoring the open instance and staring another one. I have to kill and restart FF and then everything is OK. BTW I most surely can open multiple instances of FF, I have three open right now.

Does it still happen if you stay under 50% memory usage during hibernation?

How can I check that? I know there's a command to check memory usage. I have 8G and my swap partition is 5G ... AFAICT that's never been insufficient.

You are going to have swapping issues when resuming from hibernation with only 8GB unless Firefox has been recently started.

Any possible diagnosis? Anyway, heck, it's a very small matter.

2 /boot 0 % mem

                    total        used        free      shared  buff/cache   available

Mem: 7870 3019 4386 39 802 4850 Swap: 5119 449 4670

... I'd have thought I have lots of freeboard.
