Freeze unused tabs so they stop sucking your system resources
A fun new “tab freezing” feature in Chrome 79 will help prevent your browser’s overflowing tabs from running background actions and eating up your CPU. They’ll still use system memory, so be diligent about how many tabs you really need to keep in your browser. This automatic “freezing”—which kicks in after five minutes of inactivity on a tab—won’t happen unless you flick on a Chrome flag, though.

10 years ago, who would have thought having 100 browser tabs open would not only be "a thing", but for me a norm??

Excuse my French, have you cleaned your crap out?

I don't know what OS you are using. If it is Windows, you have two places where temp files may be camping out and taking up space, (which, in some cases can be significant) and, of course, the recycle bin, as well.

There are often also many log files on machines with old installations that can build up.

There was a great tool called CCleaner, (Crap Cleaner) but I hesitate to recommend it because it has become bloated, very commercial and rather controlling

Just some ideas for getting a little more room on the HD.

That may just give you some space Good luck.
