I wish there was a way to save or "favourite" filters. I often find setting them up to be tedious enough that I just scroll through everything instead.

thanks for the PSA, I use the network tab alot and was still unaware. If you hover in the field the '?' symbol will actually link to this help page.

when you filter the requests and export an .har, the archive will include only the requests listed. For adhoc extraction I then poke at the har with jq to get what I need.

I'd like to know if there is a way to have FF developer tools automatically update CSS like Chrome does if you add a directory to its sources tab. Very useful.

I find Firefox dev tools to be so much better than Chrome's. I know at least 2 people I got to switch main browser just on the basis of that.
