Hi,
Once in a while I try to clean up my tabs.
First thing I do is use "merge all windows" to put all tabs into one window.
This often causes a memory clog and firefox get stuck in this state for 10-20 minutes
I have recorded one such instance.
I have tried using the "discard all tabs" addon, unfortunately, it is also getting frozen by the memory clog.
Sometimes I will just reboot my PC as that is faster.
Unfortunately, killing firefox this way, does not save the new tab order, so when I start firefox again, it will have 20+ windows open, which I again, merge all pages and then it clogs again !
So far the only solution I have found is just wait the 20 minutes.
Once the "memory clog" is passed, it runs just fine.
I would like better control over tab discard. and maybe some way of limitting bloat. For instance, I would rather keep a lower number of undiscarded youtube that as they seem to be insanely bloated.
In other cases, for most website I would like to never discard the contents.
In my ideal world, I would like the tabs to get frozen and saved to disk permanently, rather than assuming discard tabs can be reloaded. As if the websites were going to exist forever and discarding a tab is like cleaning a cache.
From a practical standpoint, it's hard to imagine what you could possibly be doing where it's beneficial to have a thousand tabs open.
If I'm writing a research paper, I might want 5 or 10 tabs open at a given time. Let's say I'm a little chaotic so I get up to 20. And then limitations on my working memory kick in, and having any more open tabs actually makes me worse off.
But then let's suppose it's a thesis that's 50 pages long. So I might be relying on 40 or 50 references. I'm not relying on them all at the same time, right? So I definitely don't want to keep those tabs open all at the same time.
What I could do, and what you could consider, is either bookmarking things or using archive.org to make a backup of the pages.
In one of the other comments you mentioned Facebook. That has me a little concerned again with your objectives. If it's something private on Facebook that can't be recovered later, and you need something reliable, then you have no choice but to do long screenshots or scrolling videos. If it's not reliable, then why do you care so much to keep the window open? Just close the window, remember whatever you remember, and move on with your life.
Whatever you do, here's a few rules of thumb... Your web browser is not an archiving tool. Printing to PDF is one way to archive things. There are other ways to archive things too. You don't actually need to archive as much as you might think you need to archive. Most of the things that we think might be important now actually won't be useful at all three months from now. Rarely would one actually want to have a thousand sources of information for any given task.
