Firefox 技術支援討論區

Update 91.0.1 was automatically installed on 13th August'21. Since then, after signing in to Facebook Marketplace, no listings are displayed. If I don't sign in I can see the listings. If I disable Bitdefender anti-tracking and then sign in I can see listings. If using another browser and Bb anti-tracking enabled and then sign in to Marketplace I can see the listings. I have installed the previous 90.0.2 July'21 update and all works correctly as before. What happened with 91.0.1 and should I resist subsequent updates or change browser? Thanks

Using Firefox, I am unable to share articles from The New Yorker's website to Facebook on my IMac. I get an error message that reads: "App Not Setup: This app is still in development mode, and you don't have access to it. Switch to a registered test user or ask an app admin. for permissions." I do not get this error message when I use Safari, only Firefox. There is no administrator as this is a home device, so what do I have to do on my Firefox settings to access permission?

I have no issue with Facebook when using chrome but when I use firefox (which is my main browser) there is nothing but issues. Even trying to report a problem to mozilla through browser, you get the run around. I used to love the browser but it just seems to be getting worse and worse, hell I would rather use internet explorer than the rubbish mozilla has bought out. This isn't first issue I have had, I have had passwords/bookmarks lost with the stupid sync after a fresh install but I stuck through it. I hardly use facebook anymore because of the issues they have but when I do use it, it's nothing but a headache so I use chrome just to post something or comment.
