After waiting for the bugs to be worked out, I finally moved from Firefox 2 to 3. What a steaming pile of crap! I have never been more disappointed with an upgrade. Awful hangs, using 99% CPU, extensions and add-ons that didn't work or added annoying new encumbrances. It made fonts for many sites all f'd up and even made Windows behave more badly than usual. Fortunately I reverted without any problems - so far!Maybe I just wasn't doinitrite. Anyone else have similar problems?I haven't had any problems with FF 3.0.5. like you have mentioned. The only add-ons I use are NoScript and Flashgot. Maybe once in a blue moon will a page freeze and then I'll have to close it via Task Manager.Dunno if it makes a difference but I'm running FF on Vista Ultimate x64.I had a similar negative experience between 2 and 3. Then it unexpectedly corrected itself. Maybe the same will happen for you, Ricky.Too many extension will slow down to freeze...I use it and it is a lot slower than it used to be, but I do have quite a few extensions.I will try jupiter999's suggestion and see if that helpsIt's been fine for me, with the exception of certain add ons that don't appearPresently using it no problems encountered.Tried it and it was fine, had nifty features similar to Opera Browser. I also liked the way it looked better. I was happy........Until I tried to use IDM (internet Download Manager) which is an extension I use to bulk download rapidshare and megaupload links.It crashed every time I tried it. Also right clicking and doing "save as" caused it to lock up most of the time. No thanks Mozilla, I will stick with 2.I should have listened to the old saying... "Dont fix it if it aint broke." I use vista Ultimate 64 bit as well.It's best if you could report this to IDM website and Mozilla also...Quote:Originally Posted by GemeinesI should have listened to the old saying... "Dont fix it if it aint broke.""If it ain't broke, don't fix it." ^_^;And yes, I would agree that that saying is very appropriate for software and hardware upgrades. However, in Firefox's case, my understanding is that Firefox 3 was not purely cosmetic. It was largely concerned with several security loopholes which were inherent to the architecture of Firefox 2. Like all browsers, it has proven penetrable and exploitable itself, but I guess my understanding is that "people who use Firefox 3 today are as safe as people who used Firefox 2 in 2006; but people who use Firefox 2 today are playing with fire." Or some such. I could be wrong, *shrug*, don't really know much about the Mozilla project and don't really care, just so long as it's free, fast, and spyware-free.
