Mike, Thanks for your kind reply. 1) I have no clue how to find the web map. Have searched for both it and "My Content." Nothing comes up. Am on a Mac (10.6.8), using Firefox 17.0.1. Happy to send it if I can find it. 2) Last few days, things have gotten worse. - Lots of spinning beach balls. - Very sluggish - If I go away from the computer for awhile, when I return, FF is almost always frozen. Requires a restart to get any activity (and/or to get rid of the spinning beach ball). - And worst of all, now, 1-3 times per day, am getting Kernel Panic attacks that totally shut down my computer. And each time it happens, it seems to be when I'm trying to do something with Firefox. (Seems to especially happen when shutting FF down.) I also have to force quit FF often. Just holds up. 3) A few things you need to know. - Problems seemed to start with last update. - I have three windows open, with several tabs on each (most related to current projects). I realize this might be part of my problem, but the problem did not exist before last update (with same windows/tabs config). - Am always starting in safe mode, but the problems still exist. (In fact, I seem to notice very little difference between starting in safe mode and not doing so. Pretty much the same problems in both. Only slightly worse when not in safe mode.) - Have emptied cache a couple times. It seemed like the first time I did this, there was a noticeable improvement. But it was short-lived. - I seem to be having no problems with other programs on my computer, only FF. This is becoming very frustrating - really need to resolve this. Thanks again for any and all help. Jerry jdavid69, It is likely that your web map is surpassing the capabilties of the firefox browser on the mac. How many layers and features are in your web map? Check the size of it in your My Content. If you can share the web map publicly and post the URL here, we can take a look. Thanks, Mike
