open uBO logger, reproduce the issue, see in the logger which filter from URL Tracking Protection is triggered

[maktub1]

*$removeparam=from,to=~passport.jlcpcb.com

Edit: Just looked up that domain. Should I be sketched out?
Edit2: The dev tools network tab shows no xhr to jlcpcb.com

[maktub1]

[maktub1]

I added $to=~passport.jlcpcb.com,removeparam=from as a custom filter to double check (while AdGuard/uBO – URL Tracking Protection was disabled). That's the one that's breaking the loading of the email list. If emails come in while it's broken, they do load, but reloading the mailbox makes them all disappear.

[mapx-]

it's an error on AG side converting
@@||passport.jlcpcb.com^$removeparam=from
to
$denyallow=passport.jlcpcb.com,removeparam=from

[maktub1]

Both @@||passport.jlcpcb.com^$removeparam=from and $to=~passport.jlcpcb.com,removeparam=from exist in the AdGuard/uBO – URL Tracking Protection list. When I copy the list to my custom filters, then disable it, then remove $to=~passport.jlcpcb.com,removeparam=from manually, Zoho mail works. Alternatively, if i disable the list, and have only $to=~passport.jlcpcb.com,removeparam=from in my custom list, Zoho mail breaks.

[maktub1]

I could be wrong about the syntax, but doesn't "~passport.jlcpcb.com" mean all hosts except "passport.jlcpcb.com"? That would effect all XHR requests to any host with a "from" parameter (except passport.jlcpcb.com).

Edit: I think legit XHR requests to zoho.com are being altered by that filter.

[mapx-]

yes, it seems to be an error on AG side, I notified them

[maktub1]

Ok. Thank you. I guess for now I'll run a modified version of the list without that rule/filter.

@maktub1 Wait about 10 minutes, then force update the filter list (hold Shift + click on the clock icon at the end of the list) and test again.

[maktub1]

Aaand, it's fixed! Thank you all!
