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.
I tend to have ~10,000 tabs because I obsessively fail to clean up. But it never takes much memory or cpu, my PC isn’t amazing yet Firefox is always lightning quick.
I’ve never used the discard or merge windows features though, I can see why those might cause issues. I assume these two functions just aren’t optimised for so many tabs.
One addon I might recommend to help keep numbers down is Duplicate Tab Closer, which has options to specify how similar tabs can be to be considered duplicates, and also will detect across all open windows if desired.
