The next attachment is after closing the tab and firefox memory usage dropping to around 500mb.

This is after closing the twitter tab.

Hey saishydragos, how long does it usually take to get up to 4GB (just to help diagnose)? And have you tried this on Chrome? I'm wondering if this is a problem on Twitter's end, as I can't see anything glaring in the memory report.

Andrew, do you see anything out of place in these memory reports?

If you look over at the "web (pid 3332)" process, Twitter is using a ton of memory. Most notably, there is about 2.5GB of JS classes. We've seen similar issues in the past on Facebook.

I have deactivated most of my addons, leaving now NoScript, Ublock and LastPass only to test.
Firefox already passed 1,6gb usage, from the initial 600mb after opening Twitter.
So it did that in 43min.

The time for 3-4gb (when my computer usually crashes either firefox or something else I'm using) seems to be around 3 hours?

I don't have chrome in my computer to test, but I can arrange if it's completely necessary.

Saishy, can you describe how you browse twitter website in the 43 minutes test?

I mostly leave it open while I work, sometimes I alt tab to it and scrolls a little bit.

I was not able to reproduce the issue so far, while not being logged in, and looking at a trending topic which after each visit & scrolling updated the feed with more content.

I did see temporary spikes of memory, but these disappear after a short moment.

In the memory report, as shown in comment 8, can you refresh the page, open it, and check the Record call stacks checkbox at the top, then come back 10/20 minutes after and take a new snapshot?

This would record the call stack where the memory got allocated. Then, choose the view "Aggregate" and group by "Inverted Call Stack".
This should hint at which part of the website causes the leaked memory to be created. Then look at the most prominent case.

After, change the view for "Dominators" and labeled by "Call Stack", should highlight the paths used to keep this memory alive.

So I've disabled now NoScript, Ublock and LastPass, and the problem seems to be gone...
I will try to test each individual addon for the next days, but if it's really one of them I'm not sure where I should report?

I am trying to get it to happen again but I've not even sure I've been having success or not.
With or without addons, I haven't been able to get to 3-4gb, and I'm not sure that if 1.5gb is normal usage or not since I've been basically using it broken for so long.

It will take some time to get more data, sorry.

I did it since the problem appeared back today, and I have no idea what is going on!
Sorry! I'm attaching the snapshot...

Memory snapshot taken according to Nicolas B. Pierron instructions: https://drive.google.com/file/d/1siDVdsqMZtNyckr8EiWsLF9laEr0ZXDx/view?usp=sharing

Looking at the memory snapshot:

• A single chunk related to the HLS video player, holding fragments, which sounds like live memory used to play a video.
• Multiple HTMLImageElement where each holds on a __recatInternalInstance value which has a chain of objects held by their return property. These images are also capturing what looks like a shadow dom.
• Multiple webpackjson which are held alive by a global array.
• A sandbox with what seems to be LastPass extension code.
• A __reachEventHandlers property holding on memory.

Nothing which stands out as being highly accumulated yet apart from the images and the React properties.

This is another memory snapshot of the same tab after 3 hours: https://drive.google.com/file/d/1RF11D_W74TdcdAhjd9biDuXPqsRKuuoZ/view?usp=sharing

The memory consumed by JS between 20 minutes and 3 hours looks relatively similar at ~185 MB.

I do not know why about:performance will show so little memory compared to the task manager. If there is any memory issue to investigate, the reference is about:memory at the moment, as it gives a detailed view of the memory allocations.

This was taken after at least 5 hours of firefox open on twitter, memory usage seemed to be around 1600mb, ublock and noscript were on (No LastPass), but noscript was not set to restrict pages.

I flagged this memory report as private, as I would expect that you did not intent to make this content publicly available. Marking it as private implies only a few persons within Mozilla will have access to this content.

Looking at the details, in the process web (pid 15160), the explicit/window-object/top(https://twitter.com/home) entry consumes 193.17 MB.
While twitter is the biggest memory hoarder in this memory profile, this does not sounds alarming nor representative of a leak, as opposed to what is reported in comment 6.

1.6 GB is what Firefox consumes for all processes, accounting for all opened tabs.

Thanks! Sorry I didn't know the information might contain something I didn't want anyone seeing.

So yes, by all accounts twitter doesn't seem to be the one bloating, just that as is reported in comment 7 closing it will reduce the memory use to around 600mb.

Ok so after extensive testing I'm 99% sure it is the LastPass extension.
I have no idea why but it can explosively increase the memory ram usage at some situations, which Twitter seems to be able to trigger.
Closing the tab will release the memory, but nothing else will.
