firefox - slow "List all tabs"

"List all tabs" (down arrow in top right corner) takes 5+ seconds, depending on cpu (i5-3320M CPU @ 2.60GHz) load, for me to open that list. I have 2038 tabs currently open, but how computationally intense it should be to get that list? I have tried on my other machines with faster cpus and with much less tabs and it still takes "noticeable" amount of time. Has anybody else noticed this?

I never have that many tabs open, think my personal record is 10 or so. I thought each tab opens a new process, and there's some juggling between them, maybe in javascript...

Is it this bad with firefox-bin ?

Still don't quite get the reason for doing this. I quit my browsers frequently force memory garbage collection...

Sounds like the wrong tool for the job.
If you really need all those URLs, please add them (sorted and categorized) as bookmarks, as finoderi already suggested.

There is more to the eye as just a list of tabs. You are lucky that your browser did not crash on you already.

I tried holding down control-t for a minute or so to generate a thousand or so more or less empty tabs. After a lot of CPU churn (using on average 1.5 cores - so perhaps on a dual core machine it's starting to get swamped) it settled down but it used 3.3GB of RAM and has maintenance cycles. I have enough RAM to keep it as RSS instead of swap, so it's not a big deal in terms of swap usage, but the CPU maintenance cycles does consume some CPU once in a while.

Agree bookmarks is a better idea, saves memory and CPU/memory cycles.

BTW this is on my machine with the fastest memory (i7-2700k quad core/8 thread), though it's only DDR3-1600 I hit about 20GB/sec, which makes a difference when working with a large amount of memory that can't be cached. I suspect that despite having enough memory, using an older machine that only has 4GiB/sec RAM access speeds it would be 1/5 the speed right there. (still haven't figured out my quad channel DDR3-1066 (E5-2690v2 10C20T) seems slower in RAM speed than my dual channel DDR3-1600 in memtest86+ at around 14GB/sec or so(?), but that's getting off topic...)
