(Inventory) "Sell" button's gone [ES 9.0.2, FF 50.0]

[SakhJack]

As title suggests, enabling newest ES in live version of FF just makes "Sell" button in item description box disappear.

Looks like this

I disabled everything I could think of: adblock, noscript, https everywhere, steamdb; nothing seems to work

Tried beta (51.0b1), still nothing

As a side note "quicksell" option is still not functioning

[thomas-ashcraft]

Still actual.
@jshackles how can we help with this?

upd.
Strange thing: bug appears only in Steam inventory context. Other game tabs in inventory are not affected.

[thomas-ashcraft]

Common sell button appears if page loaded through HTTPS.

Quicksell still not appear at all.

FF 50.1.0 / ES 9.1.1

Problem is still there. (Firefox 54, Enhanced Steam 9.4)

• Maybe is not only for Firefox? Inventory Sell Button Disappears Enhanced_Steam#1237

• I find if i choose one card, for example, and when i change the selector from "All items from Steam"* to "Community"* (or vice-versa), the sell button appears, but if i select another card it dissapears again, and sometimes you can do the trick again, and other times the inventory screen goes to black.

(*) Spanish translated, i don't know if what are the original english texts.

The only time I ran into this issue I've traced it back to a SteamID miss match, between the ID saved in ES's cache and the one of the user currently logged in.
I'll look into providing a test for this to make sure.
