Firefox/LibreWolf/Waterfox/Zen - Facebook "Like" selections blank

UncleSpellbinder · June 7, 2026, 6:07pm

When attempting to click the “like” button on Facebook, the selection box is blank in LibreWolf or Firefox. No issues with Brave Origin or Vivaldi.

Brave Origin/Vivaldi:

LibreWolf/Firefox:

No clue what’s going on here. Anyone have any ideas?

It looks okay to me here with FF Nightly. Have you tried the usual tests? New profile, no extensions?

UncleSpellbinder · June 7, 2026, 6:34pm

@jrichard326, Huh? No it doesnt…

jrichard326 · June 7, 2026, 6:41pm

You are right. sorry. I don’t normally do FB. Apologies.

UncleSpellbinder · June 7, 2026, 6:49pm

No worries!

Blank on Waterfox also…

and on my LibreWolf.

Hmmm. This is strange. Obviously there must be a shared setting between Firefox and Firefox-based browsers her that is broken.

UncleSpellbinder · June 7, 2026, 11:14pm

Anyone who uses Floorp willing to test this?

Can confirm same is present in Zen 1.20.2b

SOLVED

I think

Seems to be uBlock Origin. This is the result in Firefox, LibreWolf, and Waterfox.

uBlock Origin DISABLED:

uBlock Origin ENABLED:

I only marked as “solution” because the culprit has been found. I’ve enabled and disabled uBlock Origin lists, checked configs… nothing has worked so far.

This must be some settings under filter list annoyances/social widgets. Set them one on/off after another.

Seems they are working on it at the ublock side, but it is one of the cat and mouse things with Meta:

# Facebook is watching uBO everyday, so don't expect the solutions would last lo…ng or be breakage-free. # The best solution is stop using this anti-user site. # Force update quick fix list by left clicking on [this link](https://ublockorigin.github.io/uAssets/update-lists.html?listkeys=ublock-quick-fixes&manual=1) before reporting. --- **About blank reactions issue:** The issue occurs when any scriptlets related to `xhr` (like `jsonl-edit-xhr-response`) are involved which are needed to remove ads. I don't know why. gorhill doesn't have Facebook accounts so it's impossible for him to investigate. Anyone who can investigate why the issue occurs is welcomed.

[/TOT*]

I don’t use any sites, whatsoever, which demands my content blocker to be turned off.

PS. May GAFAM burn in hell and take with them the 1%.

THIS WORKS -

Disabling the uBlock Origin “built-in” filters and keeping all other filters you’ve selected or added enabled seems to “fix” the problem. More of a workaround until uBlock fixes the issue, I suppose.

UncleSpellbinder · June 8, 2026, 3:44pm

BETTER FIX -

No disabling of filter lists required.

Add the following to your custom filter lists (My Filters)…

www.facebook.com#@#+js(jsonl-edit-xhr-response, ..node[?.*.__typename=="SponsoredData"], propsToMatch, /graphql)
www.facebook.com#@#+js(json-prune-xhr-response, data.viewer.instream_video_ads data.scrubber, '', propsToMatch, /api/graphql)
www.facebook.com#@#+js(jsonl-edit-xhr-response, ..node[?.__typename=="MarketplaceFeedAdStory"], propsToMatch, /graphql)
www.facebook.com#@#+js(json-prune-xhr-response, data.viewer.sideFeedUnit.nodes.[].new_adverts.nodes.[-].sponsored_data, '', propsToMatch, /graphql)
