even im asking myself how you can handle that
pretty simple
i don't use the majority amount of them; i really keep them there just as a higher priority placeholder than a bookmark which I also have stuff tons of (at least 10k+ by now combined)
it's not really doing much to performance when you have 32 gb of ram to handle it...my other computer however, it is a problem
in fact, I'm about to clean some of them out (aka maybe 5-6 tops)
I only recently started doing this; most of it is really just weather stuff so subtracting that and almost all of them are gone.
