I have noticed that I can’t post anything on Github when I use Firefox (Arkenfox). I can write a draft, but them the “Post” or “Comment” buttom never actually work. I have tried disabling uMatrix, but that doesn’t fix it.
Does someone elese face the same issue ?
Works for me.
I believe Arkenfox explicitly said that uMatrix should not be used. Also, did you carefully read the Arkenfox wiki? You should have created a user-overrides javascript file for your overrides. If you just used the default Arkenfox configuration, there would most likely be issues.
Begin by updating or creating your user-overrides file, then overriding settings that are toggled or disabled by Arkenfox.
I, for example, disable privacy.resistFingerprinting since I believe the trade-offs are substantial, but know lack of decent fingerprinting protection shouldn’t be taken lightly
No longer maintained, the last release was Sept 2019 except for a one-off patch to fix a vulnerability
- Everything uMatrix did can be covered by prefs or other extensions: use uBlock Origin for any content blocking.
uMatrix is superior to uBo, here’s why :
Why is uMatrix needed when uBlock Origin medium mode is “all you need” ?
Let’s say you are visiting github.com, with uBlock Origin Medium mode, you will allow content from githubassets.com and from avatars.githubusercontent.com
Now with uMatrix, you will allow scripts from githubassets.com, and images from avatars.githubusercontent.com
So, let’s imagine a scenario where an attacker gains access to the githubusercontent.com website, but not the main github.com website. This attacker is now sending malicious scripts to users from avatars.githubusercontent.com. uBo users will run all those scripts, while uMatrix users will not.
I am not sure what is causing this issue, so how I can make overrides for it ?
I use nuMatrix, an actively maintained fork of uMatrix. At least every year or so.
Plus, it’s not like those software change overnight, so I am not worried about vulnerabilities. I am also working on updating filters, etc.
That sounds like an interesting project. I personally haven’t used nuMatrix, but I’ll keep an eye on that. Out of curiosity, what about uBO’s hard mode? Does that change anything?
Anyway, that is diverting from the main topic. Have you fixed the issue?
uBo’s hard mode doesn’t change the fact that you have less control over what runs on your browser.
No, I haven’t fixed the problem yet.
The problem is is that Umatrix is still deprecated. If an exploit is found today, it is highly likely that it will not be fixed. POutting this together with the fact that there are only a few minor things that Ublock origin cannot do, it would make little sense to recommend Umatrix.
Again, people are free to use it, we won’t stop them, but its sadly not suit for a recommendation.
FYI, he’s talking about nuMatrix and not uMatrix.
I haven’t experienced any issues with FF + AF + VPN and Github.
I just reviewed a PR on github today (including inline comments/suggestions) from a default Arkenfox profile with no overrides. I didn’t encounter any issues personally (but it was just a single review so ymmv)
Its worth noting that Arkenfox very recently changed from RFP by default to FPP as the default. So if you haven’t updated your user.js recently, you may still be using RFP by default which may or my not cause problems.
I cleared Github Cookies and Site Data and it fixed the problem. I was getting an error 422so I understood maybe cookies were making problem. And I had a lot of cookies from previous sessions.
Problem fixed !
Some guy making a fork doesn’t really change it immediately. There is no saying how well it will be maintained nor how trustworthy the dev is.
I not saying he is untrustworthy, but at PG we generally first watch programs mature and let them develope a track record.
I don’t advocate for recommending it on PG. It’s also very technical and require a lot of effor for whitelisting domains.
You realise how almost no website (even this forum) cam run without CDNs. It’s crazy.
