UI Doesn't work when served from localhost IPFS.

[MicahZoltu]

Bug Description
When accessing the page via localhost IPFS (e.g., IPFS Desktop), nothing works. The issue is that infura appears to be blocking requests from localhost origins.

Steps to Reproduce

1. Install IPFS Companion and IPFS Desktop.
2. Navigate to https://app.uniswap.org
3. Notice that you are redirected to http://app.uniswap.org.ipns.localhost:8080
4. Notice that you are unable to get the price of any pairs.

Expected Behavior
The website works properly when accessed via localhost.

Additional Context
Probably related to #1091.

Allowing a custom JSON-RPC provider setting would at least allow one to work around this issue without having to disable IPFS-Companion.

Simplest solution is to whitelist our Infura key to work for IPFS origin CIDs from the GitHub releases

This bug is still present and still incredibly frustrating. I can't use WalletConnect at all when browsing via localhost IPFS because Infura is used for network connection (which cannot be changed) and it doesn't work from localhost.

Tentatively re-opening since it was closed without comment.
