It's just you. I notice slowdowns at popular times for social media, which I suspect are my ISP, or those popular sites, throttling traffic. But in general it is behaving how it has always behaved. I recently tried some other browsers because of a problem with the way a site was behaving (a bug in their site), and I didn't notice any difference in speed. You could see if one of your add-ons is the cause by starting it from the command line /usr/bin/firefox -safe-mode If it is fast then, restore the add-ons one by one until you find the culprit. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
