Problem with 'local' tld and domains in 8.6

[vx-github]

After the update to 8.2 FoxyProxy Standard for Firefox and not soon after to 8.6, I got problems with URLs that contained local in the hostname part of the URL.

So I rolled back to 7.5.1 and created a proxy with the follow (White) paterns:

• (wildcard) *.local.nl
• (wildcard) *.domain.local
• (wildcard) *.domain.nl

When testing the following URLs:

• https://test123.local.nl/
• https://test123.domain.local/
• https://test123.domain.nl/ ... all of them where send to the proxy I specified (according to the logging).

Then I did an upgrade to 8.6, and tested the same URLs (did a Firefox restart in between). Now only the https://test123.domain.nl/ was send to the proxy and the URLs that contained localwere not.

I consider this a bug since our organization uses .local domains for internal use (unfortunately) and this tld and domains were still working on 7.5.1.

Are you using "Proxy by Patterns" or individual proxy? Can you post a screenshot of the patterns that you have set for the above domains in FoxyProxy 8?

I used "Proxy by Patterns" (like I used "Use Enabled Proxies By Patterns and Order" in 7.5.1).

Does the Log have any useful information?

Also ...

• Open a new tab
• Open the Developer Tools (F12)
• Go to the Network tab
• Enter https://test123.local.nl/ in the address-bar
• Check the result

The logging of FoxyProxy shows which URL request are send to the proxy and which are not (mentioned in the issue). No other usefull info.

The used URLs aren't supposed to work. they are constructed so I can see if they are passed to the proxy (seen in the FoxyProxy logging). The result in the browser also gives a clue if a URL is tried to (DNS) resolve or if it is passed to the proxy and the proxy cannot find it.

I rolled back to 7.5.1 and for every test I need to upgrade to 8.6 and roll back again to 7.5.1 (to be able to work again). So you last 'Also ...' request will be done later.

BTW: I'm on Firefox 120.0.1 on MacOs.

< cut > typo in test URL, will have to redo this

[erosman]

The error shows DNS error. Firefox cant resolve the NS record for the domain. The DNS is not something that FoxyProxy handles. It is handled by the browser.

Have you enabled DoH (DNS over HTTPS)? Have you enabled Proxy DNS? (although I cant see that affecting the outcome) Have you tried nslookup in the MacOS terminal?

nslookup test123.local.nl

I made a typo in the last test, so the outcome did not reflect the problem. I will post a new screenshot.

Are you still having the issue with the latest release?

@erosman I updated Firefox to 121.0 and FoxyProxy to 8.8 and I cannot reproduce the original problem anymore and a quick test shows everything is working as expected again.
