Firefox is not showing certain informations on Facebook wall
On my wall on facebook I don't see posts about pages I liked, pictures I commented and new friendships, just like only links and statuses are viewable. This is not happening in other browsers, I checked Opera and Chrome.
URL of affected sites
Let's start with something simple: Try clearing your Firefox cache. See How to clear the Firefox cache.
Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You can use "Disable all add-ons" on the Safe mode start window. You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit") .......... If you have many extensions then you can first enable half of the extensions to test which half has the problem. Continue to divide the bad half that still has the issue until you find which one is causing it.
Ok, I finaly solved the problem - I uninstalled several extensions. I don't know which one caused the problem, but it was something that certainly wasn't necessary.
