Contract development panel error: "TypeError: t is undefined"

[catageek]

As described in title, whenever I open the contract development panel, I got this error on the right panel. The error stays even if I fill the left panel with a correct source code.

Parity version:
Parity//v1.6.0-unstable-5f154b9-20170211/x86_64-linux-gnu/rustc1.14.0-beta.2
Unknown capability

almost certainly an error in your solidity code; please paste the minimum code needed for this.

[catageek]

The error is displayed even when there is no code, as soon as I open the panel, and it stays whatever I type on the left pane.

I am currently trying to rebuild parity but I am stuck with a build error on nanomsg. I will give a feedback when I can build parity.

[catageek]

So I built parity from scratch with a fresh rustup installation, and I still have the error.

see this capture. This message appears after a brief "loading Solidity version ..."

[derhuerst]

that looks a lot like an error in the UI code. could you post your browser and operating system versions?

[catageek]

I have also this in the browser console:

I noticed there is another message that appears a few ms before the other error message when I load the panel:
"SyntaxError: In strict mode code, functions may be declared only at top level or immediately within another function"

[ngotchac]

I can reproduce it on your Firefox version. Not sure how long would a fix take ; in the meanwhile, you might want to upgrade your Firefox version :)
