I have used Firefox 3.x for some time on a XP machine. Never any problems. It is a machine that I keep running for weeks on end without rebooting. It is a workstation but rather old.

After upgrading to Firefox 4 I get problems with memory. The machine has 2Gb of RAM. I have four tabs open in FF4, about the same as I usually have had in the past. Two of them are now pinned.

When I reboot Firefox it take about 90Mb. But after half a day that is up to 400Mb. I open and close tabs during the day. After another reboot cycle memory usage is again down.

Looks like a memory leak.

Hi

I am having problems opening a pdf file in Firefox. I have Firefox v4.0.1. When i attempt to open the file it gives a blank page. I can open the file successfully in Internet Explorer 8. I am using Windows XP Professional. I have had problems with Adobe Plugins in Firefox in the past so i use Foxit Reader to open PDFs. I can open the pdf file successfully in Foxit Reader. I have the Foxit Reader Plug-In for Mozilla 1.0.1.1117 enabled.

thanks

I've been a FireFox user since the original Mozilla 0.9something beta, and I have been happy with it.

Until now.

FireFox 4, it seems, was rushed and released long before it was ready. It locks up. Frequently. In all sorts of different circumstances (downloading, browsing, watching video streaming, restoring after a crash, attempting to clear the download list, etc..). More often than not, I have to close it using the Windows Task Manager. It eats memory. Seriously, do you really expect a browser to consume up to and over 1 GB of memory and people to keep using it? The little add-ons are nice, but with the core functions so flawed, they are of little use.

If you google "i hate firefox 4" you get over 16,900,000 results! That's a public relations nightmare for any company! Do the devs here realize or even care about the damage being done now to their reputation? With extreme dissatisfaction numbers like that, they're going to be bleeding market share, if they haven't already! Even as I was typing this, with the Ask a New Question page the only thing I have open, FireFox locked up for a few moments.

After over a decade of using and support FireFox and it's ancestors, I'm going to be giving IE 9 a try.

Ever since I upgraded my Windows 7 desktop to Firefox 5 it has been a nightmare! It hangs, freezes, is unresponsive more often than working. I have to us my laptop, still on FF4, to post this or risk being totally grey before I could finish posting. I see by the comments that I am not alone in having this problem, but do not see any offered solution. Do I have to revert to FF4 to use my desktop or is a solution forthcoming?

When desired site is clicked in Google www.bywill.net appears in the destination window instead of the site address listed and a different site is displayed. This happens with IE as well as Firefox. Repeated searches by McAfee disclose no viruses. They suggested site blocking but this only stops bywell displaying its chosen site.

I hate Firefox 4! My favorite add on doesn't work, it is slow and locks up. I run Windows 7. Can I uninstall 4 and go back to the old version? If so, how?

As a former programmer, I am dismayed that such a poor version would be released! It reminds me of dealing with Windows 98!

I have Firefox 4.0 installed on my laptop. It is a work machine so there is no ability to tell me to upgrade my ram, it's not possible unless it I take it out of a non-existent budget.

I have 512 MB ram, I run Windows XP Pro with no effects on, I have an AMD Athlon 64 Processor 3200+.

Everything on my system before firefox runs takes up 120MB.

After running only Firefox with no additions, and on a blank, or only one page open with no java or flash on it (I know this because I created said pages), Firefox balloons up to 150 MB... if I leave for lunch and come back it is up to 350 MB... with the same two pages open.

Now I know Firefox uses memory, but what is the reason for this? This is not a memory leak, this is a memory hemorrhage...

If someone says I need to run in safe mode, I don't think so... the last version of Firefox 3.6 ran fine, and although it had a memory leak, it was nothing as bad as this.

I develop web pages, I use PHP and CSS... these are not memory intensive languages... so what is going on?

The previous one always asked if I wante tabs saving when I closed it but this version (4) does not.

Is there a way of making it ask?

I'm getting an error message from Firefox that says, "Something is trying to trick Firefox into accepting an insecure update. Please contact your network provider and seek help." Do you know what is going on here--what this problem could be? (I do have the latest Firefox version already installed. I have previously received Firefox error messages that say "Firefox Update Failed." However, I already had the latest Firefox version installed when I received those error messages.)
