There are just so many people complaining about Firefox 4 - all with the same basic problem - Firefox 4 consumes far-too much memory and appears to increase memory usage over time.

So far I have heard NOTHING from Mozilla regarding this problem.

Have Mozilla identified the problem? Is there a work around? When will there be a permanent fix?

Is anyone else having trouble with the back and forward buttons not working in FireFox 4? I installed 4 on an XP desktop and a Vista 64 laptop, and the forward and back buttons don't work on either installation. Does anyone know a fix for this? I tried deleting the "places" files in the profile and that does not help.

I was viewing my watchlist on Ebay, when the whole page was replaced by a page saying I had 11 viruses in My Docs, 3 viruses in Files and 11 on my hard-drive. The options to "remove" or "cancel" resulted in "You have chosen to open Best Antivirus 2011"...which meant I had now downloaded it! I scanned the computer with my antivirus program and sure enough, IT found 3 threats...each being "Best Anti Virus 2011". I have repeated scan/removal 5 times, but it is re-embedding itself each time. SO MUCH FOR FIREFOX SECURITY! YOU have been hacked!

Hi I am using a Dell laptop running win7 my FF 3.6.16 runs roboform ver 6 no problems. I have also been running FF ver 4 which has also worked OK until a few days ago when it did an update. Now the Roboform tool bar is empty except for the Roboform Icon which if you run the pointer over it says "show or hide tool bar" but if you click on the Icon it Just loads the roboform download page. I cannot move over to using ff ver 4 until roboform works

I can’t comment on Fox news, disqus is not responding. I have an account with Fox News and can login without trouble. When I try to comment or reply to articles a window will open and three dots will appear. At this point I should be able to type in a comment. The status line shows a number of servers at work but never completing a connection.

I was using Firefox 3.??? and was prompted to upgrade to a newer version. I agreed to up-grade to 3.6.16 but when I went to download this I was fed Firefox 4. I have tried using 4 for about two weeks on an old Vaio laptop running Windows XP. It is unbelievably slow and crashes in every other site. Watching video online? Forget it. I loathe this new browser.

I have just uninstalled 4 and reinstalled 3.6.16. This was very easy (a) download 3.6.16 from FileHippo or similar source. Go to your [drive name]:/programs/mozilla/firefox/uninstall folder and click on uninstall. Do not click the tab which uninstalls your personal bookmarks and add-ons etc. 4 is gone. Don't need to reboot. Just click on 3.6.16 and install. Everything up and running in one minute. 3.6.16 is what I expect from Firefox -- easy to use, lightening fast, and no site crashes (except when visiting this site, curiously enough). Will be staying with 3.6.16 for a year or so to give the nice folks at Mozilla time to (a) tar and feather those responsible for this fiasco then burn them at the stake (b) scrap 4 and (c) go straight to Firefox 5 without stopping at Go or picking up $200 as they pass.

So, my question, is Firefox 4 the worst browser ever? I dunno but it is certainly the worst Mozilla browser I've ever tried using. Do you agree? Discuss.

All of a sudden, when I put a subject in the Yahoo search engine, and I get all the "hits" listed, I can no longer just click on them and they go to the web site. NOW each time I get a box titled "Opening" that say "You have chosen to open" and then says things like "which is a: application/octet-stream' and "from: http//search.yahoo.com". Then "What should firefox do with that file?" and I can choose "Open with [Browse]" or "Save File" with an "OK" and "Cancel" button. When I try "Open with" and use Browse I get lots of choices but none of them will work. What changed? Do I have malware in my computer? I am ready to just give up on FireFox and move to Chrome, which works just fine. Any help out there????

THIS IS A MACBOOK related question. I'M NOT ON WINDOWS.

When navigating to an image after an image search (of Marcia Cross) with Google. Search page suddenly shrinks to dialogue box with a black exclamation point in a yellow diamond followed by the message: "The page at http://sanprotectionxp.com says: Windows Security has found critical process activity on your system and willl perform fast scan of system files." There's an OK button to click. I do not. I can do nothing but force quit to avoid problems but when I open Firefox 3.6.16 again same thing sometimes happens again, this time without search, but as soon as the Firefox window opens again.

I have just upgraded Firefox from 3.6.16 to Firefox 4 (OS Win XP) I had Fire FTP as an add on, but after upgrading it disappeared from the Tools Menu (along with all my accounts details) I then re installed the Fire FTP Add On but it does not appear in the Tools Menu, where has it gone? Firefox 4 appears to have reinstalled previously removed Extensions/Add ons The Tools Menu doesnt have anything in it. How can I roll back from Firefox 4

SOS!!! Yesterday I opened firefox through a link in my email. The window opened with two tabs: one is the new link I opened and the other one is for restoring my previous sessions from earlier time. Since firefox was working a bit strangely so I tried to open the new link several times. Now problem happened. When I try to restore sessions, it only restores to the last one I had with just two tabs. Even though I kept clicking on "restore session" within the restore session window, it won't show all my previous tabs information but stuck with the two tabs lastly seen. And it continue to repeat these two tabs no matter how I choose (even by deactivating the new tab window, it still doesn't restore to original status). I thought by shutting down my computer completely, maybe firefox will go back to my previous settings, but this morning when I turned it back on, it still stick with the last two tabs opened yesterday. Where can I find all the old tabs I used to saved? SOS!!!

There are a lot of changes in Firefox functionality that made some loyal users angry enough to drop FireFox: https://support.mozilla.com/en-US/kb/ask/discuss?page=1

Those are not confused users but rather people that consider some of the last changes not only controversial but rather completely unacceptable since they affect their productivity.

Please note, that those are not just questions asking for help but rather a frustrated state of mind telling that you have broken real useful functionality that you shouldn't have touched, as in the principle "if it isn't broken, don't change it".

Those affected features are: 1) Save All Tabs / Save Group Tabs - now removed from FF4 2) Move Tabs / Bookmarks Around - now removed from FF3.6.16 3) Reload button etc

I have a mac os x ver 10.6.6 and firefox version 3.6.16. I installed an HP Photosmart D110a printer (had a HP printer before that died) this morning. This evening, all of a sudden, I started getting the "host does not exist" message when I would enter a partial url address in the location bar of my home igoogle page on firefox. Usually, firefox automatically completes the url, I hit return and my website comes up. Now I just get the does not exist screen. I also had to update Adobe a couple of days ago.

v 3.6.16 . this happens on http://att.my.yahoo.com/?_bc=1. featured top stories. does not do this from ie.

FireFox 3.6.16 want sto update to 3.6.18 (45 minutes), but when I tried to download it at the library (under 1 minute) I got 3.6.19 - is that compatible with Win2000 and 56k? What other differences are there?

I use Lotus Notes web based email (iNotes) for work. I normally use Firefox as my browser. All versions so far have worked fine. I upgraded to Firefox 4 last night and got a big shock when I went to my iNotes email. Although I could log in just fine, none of my folders (inbox, sent mail, etc.) would show any of my emails. Could this be a different default setting that needs to be changed or is it a "bug?"

I downloaded FireFox 4 on Friday 25 March 2011. It would run ok with my saved Bookmarks and is faster BUT when i do a Google Search, Firefox 4 ALWAYS freezes/crashes. Windows Task Manager displays the message "Not Responding".

Today, I have re-installed FireFox 3.6.16 because of the Freeze/Crash problem that i'm encountering with FireFox 4.

When downloading Firefox 4.0, DigitalPersona Personal 4.11.3805 with DigitalPersona Extension 5.0.0.3790 (from Mozilla Firefox Add-Ons) is incompatible. Fingerprint swipes only open the DPP application's Home Page. I had to uninstall FF 4 and re-install FF 3.6.16 in order to utilize fingerprint logon recognition.

DigitalPersona will no longer support DigitalPersona Personal as is evidenced by the following email I received from PersonalSupport@digitalpersona.com:

"Thank you for contacting DigitalPersona. We are extremely sorry to inform you there will be no update releases for DigitalPersona Personal in the future. We are also sorry to inform you there will be no updates for Firefox 4 nor Internet Explorer 9. You certainly can try to use either one, if they work for you great!. If they do not work, you will have to decide to either keep DPPersonal and forgo Firefox 4 or IE 9, or vice versa. DigitalPersona, regretfully, is leaving the consumer market and is focusing on numerous business and legal applications. In fact, again sorry to inform you, DigitalPersona Personal will not be supported after Mid-April of this year."

Hardware/Software:

Computer: HP DigitalPersonal Personal: 4.11.3805 OS: Windows 7 64bit Browser: Firefox 4 Fingerprint Reader Sensor: Validity Driver: 2.0.0.1

Will there be an update to this extension, or are there other software options to make the Validity Sensors, Inc. fingerprint reader compatible with FF4?

I tried FF 4 twice and the result was the same in my two experiments. FF 4 resets my PC.

I am a veteran Mozilla product user since Netscape days and I don't know why this happens now. I uninstalled 3.6 before installing 4.0.

No, nothing changed.

All of a sudden, the PC resets itself and this happens only when FF 4 is installed and being used.

FF 4 doesn't crash. No error message.

This a 3 year old XP machine, clean, carefully maintained and used only by me, a 40 year old experienced PC user.

So, what should I do?
