Legitimate URL Shortener breaks many Facebook pages (not profiles)

[ctp9]

Describe the problem below this line as meticulously and detailed as possible (incl. pagelinks if any)

I'm not sure how to log or describe this - but Facebook pages (not profiles) get significantly broken. If you own a page and go to "Manage" your page - lots of elements simply no longer load with Legitimate URL Shortener activated.

Pages freeze and are unable to render the functions of the requested page. Refreshing does not fix it, but only disabling the Legitimate URL Shortener fixes all these issues.

To replicate all these issues - you need to have created your own Page, and then try to Manage / edit Settings, etc.

Facebook pages use detailed URL descriptions for editing pages, and I think there are many conflicts in the current rules that are too restrictive and break everything to do with Page management.

I don't have a Facebook account of my own, so I'll assign this to @iam-py-test for the immediate time being.

[iam-py-test]

I don't have a Facebook account. @ctp9 please take a screenshot of the uBlock Origin logger while reproducing the issue

[ctp9]

Updated original post with logger text file attached.

Page management tools seemed to work better today - so I partially suspect Facebook servers themselves were acting up when I submitted this report yesterday. But do still take a look through the log please and see if you can find any issue(s) and/or if there's any room for improvement/optimization, etc.

I'll upload more logs in the coming days from various sections of Facebook where elements get broken.

[iam-py-test]

@ctp9 please try the following filter in your My Filters tab: @@||facebook.com^$removeparam=__s

[ctp9]

Testing - will report soon.

Hmm... @ctp9 try installing uBlock Origin in a Chrom(ium) browser and add Legit URL, see if that is the issue In the mean time, let me see if I can convince someone in my household who has a Facebook account to help me repro

One of the responses on the Mozilla bug tracker:

"Chrome has the same issue, it's a Facebook problem."

[DandelionSprout]

I can borrow my mom's Facebook account to do surface-level skim tests, but I'd need to set off an hour to do so.

[iam-py-test]

@ctp9 did the filter @@||facebook.com^$removeparam=__s fix the issue? As Facebook is very popular, I'd like to fix this

I'm still testing but so far seems to be working better than when I first submitted my report. I am still, however, occasionally experiencing the Mozilla bugs reported earlier regarding image loading when administering my own Pages, which seems to be universal across Chrome and Firefox.

Please also check out the "Activity Log" in the settings section of Facebook. Some things get broken there also when expanding/collapsing section trees. The entire Activity Log section sometimes stops loading with Legitimate URL Shortener enabled.

[iam-py-test]

If that filter seems to help, I'm going to add it for now

[ghost]

So, is this reproduceable?

Do you have a FaceBook account? I don't and neither does Imre, so reproing is hard

[ghost]

Do you have a FaceBook account?

yes

[ghost]

so I created a fb page, and I haven't observed any issues

Probably the temp fix from https://github.com/DandelionSprout/adfilt/commit/6f22b1c686e0ffa23e77a0bc82beb5eb254b4888 Try adding @@||facebook.com^$removeparam=__s,badfilter and retesting.

[ghost]

no issue spotted on my end

[iam-py-test]

Even with that filter + clearing cache & cookies (and re-sign in)?

[ghost]

I'll see if I can make some time available for more testing.

[DandelionSprout]

I sadly can't help after all, because my mom's PC died some days ago (A missing CPU retention bracket led to fan mounting problems, in turn causing bent pins on the CPU socket), and they sure haven't had any haste in pursuing a new PC to put their SSD into.

[krystian3w]

If the pins haven't flown off the processor or motherboard, you can try to straighten them out instead of throwing +90% of the computer away in the electro-junk.

I would consider if you can buy a used cpu or motherboard itself very cheaply (cheaper than some finished PC with 6th or newer generation Intel if parent don't like oldie AMD and AMD Ryzen).

[ghost]

I haven't reproduced any breakage.

[ctp9]

At the moment things are working good. It may have been the Facebook / Mozilla bugs that were described earlier after all...

[iam-py-test]

If Facebook is still working well, I think I can close the issue

[ctp9]

Wait - I'll test a few more times and we will close it with my final confirmation. Just been busy and didn't get to re-test since last time.

[DandelionSprout]

Given there seemingly hasn't been any problems with this from any involved party for approx. 7 weeks by now, I think it's safe to declare this a closed case for now. Comments will remain open.
