Installed this because the previous extension I was using got taken down, and within an hour I was blocked from opening any Reddit links due to error 429: too many requests.

I've switched between many extensions which add Reddit comments on YouTube over the years, and haven't had this problem with any of the others.

This add-on has been working without issue since installation. However, in the last few weeks there is now an issue.

The issue seems to be that this add-on seems to be triggering some sort of rate limiting from Reddit's servers. It has nothing to do with YouTube. When on Reddit, if I open several tabs the website will refuse to load unless I come back after a 5-10 minute break, activate a VPN, change DNS servers, etc. Disabling this add-on has completely fixed the issue of Reddit not loading. Hopefully this will be fixed in an update.

I believe that if this add-on was updated (as of this writing it has been about 8.5 months without an update).
