Firefox for Android Support Forum

I'm experiencing a strange problem with this Google review-link for my customer:

After the login-procedure for Google I end up with a 404-Error and can't find any help at Google. I also wonder where that local URL is coming from.

It works on iOS and on Chrome or Samsung Internet on Android. Here's the error message: The requested URL /local/writereview?placeid=ChIJazm4u47ql0cRsiGgJDKAtQ8&source=g.page.m.ia._&laa=nmx-review-solicitation-ia2 was not found on this server. That’s all we know.

I already tried to disable safe browsing and cleared my cache. Nothing helps. Looks like a bug.

I am unable to use Firefox on Android as no webpages load when I have Adguard enabled on my phone. Adguard is an ad block that works using a local VPN. It works well with all other Android browsers except Firefox. I hope there'll be some solution to this issue.
