Add a setting to open fully-expanded element picker or have picker remember the last chosen view by default

[u-RraaLL]

While I understand the minimalist approach default picker view, so as not to confuse people with more options that they might need, I'm pretty sure any experienced filter maker will always expand picker to its full view.
Having to expand it every single time gets rather annoying quickly...

Can we either:

• Get a setting to launch picker fully-expanded (can be hidden if "developer mode" is off|)
• Have picker remember the last chosen mode, similar to uBO's popup, where the "more/less" buttons originally came from

?

It does remember and restore the last state: https://github.com/gorhill/uBlock/blob/801b4679e9d6ffcf15d86c44a2122fa62e9779b2/platform/mv3/extension/js/picker-ui.js#L369-L372

I can reproduce the issue with Firefox. Somehow browser.storage instanceof Object is false in Firefox.

Tested on Chrome just now and installed mobile edge to test as well. Works on both indeed.

One thing I've noticed on Edge, though, is that the font on the selectors list is normal size there.
So I guess what I've reported here, with the font being too large, is a FF bug as well.

Here's a comparison between Firefox and Edge selector lists on mobile. Firefox displays almost twice less details than Edge does:

Firefox finally got the update (.1640, the previous was skipped).

The picker expansion seems to keep across instances. So that's fixed.

Unfortunately, the selector list's font didn't get any smaller. In fact, it got slightly bigger.

I picked the same element I screenshot before, first selector got a 5th line.

Given my Android version is too old to be able to test uBO Lite in Firefox, I can only test with the emulator in Firefox dev tools, and when doing so, the computed font size is 13px, same as the font in the text area:

Okay, I've been trying to debug this. I tired USB debugging and it still showed 13px computed size for both textarea and #candidateFilters even though they clearly displayed different sizes...

Ultimately, I've found out that overflow-y on #candidateFilters somehow causes this. The size resets to normal when that rule is disabled.
But, as you can imagine, this breaks scrolling. I tried all default values and only "auto" or "scroll" allow scrolling, and both enlarge the font display.

I'm really not sure why this happens or how to fix this. Any ideas?

[u-RraaLL]

Okay, I've figured it out. It's an issue with Firefox's Automatic font sizing, which I believe is enabled by default. (I guess it automatically enlarges scrollable text items. No idea why uBO isn't affected though...)

After disabling it and restarting the browser, the issue is gone.
