Firefox is very slow when using Facebook and most of the time it can open 2-3 posts only in the 'Newsfeed'instead of opening a lot more.
Nowadays when I log into Facebook through Firefox, it opens only 2 or 3 posts of the News Feed (it is happening very frequently but not always). As far as I can remember, I never experienced any such problem in the past, except rare and occasional crashes which were solved instantly. I am facing this problem since 5-6 months.
Whenever I face such problem with Firefox I log into Facebook through Google Chrome to check whether my internet connection is working properly and have found no such problem with Google Chrome. I have also checked to see whether this problem is caused by hidden updating of some apps or automatic scanning by antivirus but found none. I have also tried 'Refresh Firefox - reset add-ons and settings' and uninstalling and installing again but the problem was not solved. Any solutions, please?
Please make sure that there is not an issue with any addons or hardware acceleration by trying Safe Mode:
