Odd resource Hogging by Firefox Version 6 & 7

I have seen this thread in two forms: firefox using too much CPU and Firefox using too much memory.
I have tried all the suggestions listed in what threads I can find, including running in safe mode.
Basically, I run FF version 3 or 4 and it runs fine.
I upgrade to Version 6 or 7 and immediately upon start up, Fire fox consumes 45% of my CPU cycles, 200,000k + of my memory, and 100+ handles. Open up 2 tabs and it rockets to 60% CPU, 300-400,000k memory, and 2-300 handles. Each site takes between 30-70 seconds to load, even local ones. It continues to grow the resources slowing the browser down even further as it is used. I downgrade to version 3 or 4 or 5 and it's back to normal.

Facebook news feed cpu resource hog on Firefox.

Anyone else seeing this bug on Firefox. I'm using 32 bit on netbook. When I switched to other tabs, the cpu usage drop immediately. When I switched back to facebook news feed/home tab, the cpu usage will shoots up to 100% and does not drop.
I only have vimperator and noscripts addons. I've already tried disable javascript on facebook but still the same. No problem with Chromium, though. I've noticed recently that google plus feed on chromium become cpu hog too on my netbook but not on Firefox.
Edit: Added link from Facebook Help page.

No, I haven't tried with nightly, but I did tried with aurora from heftig repo and still the same problem on newsfeed. Two weeks ago, facebook on firefox, the cpu usage was normal.

Firefox Version 36.0 Hanging with odd Script: chrome://browser/content/places/browserPlacesViews.js Errors / Lost all bookmarks including Sync.

Hello - Yesterday 4 different PC's updated automatically to Firefox Version 36.0, they are all Windows 7 x64 Systems with the latest patches, one of them is a work / corporate PC running a slightly older version (34 I believe).
Since the update all of my bookmarks have been lost and seems that sync got wiped out as well. I had a few thousand bookmarks all organized in folders and they are all gone. Whenever I click on the bookmark menu item firefox will hang and eventually give me the following error with different numbers at the end of the line (varies on each system as well as the same system). See attached for an example.
Script: chrome://browser/content/places/browserPlacesViews.js
Even if I start Firefox in Safemode I get the same results / behavior (the hanging) I can't even access the bookmarks menu to try and restore them from a backup. When I do that Firefox will hang and never come back, I have to go in to task manager and end the task.
I've tried "Refreshing" at work I tried uninstalling / installing the newest as well as a version 35 version of firefox and have the same exact issue. I removed all of the plugins, I've even tried a full on reset of firefox and have had no luck whatsoever .
It appears that I have lost about 10 years of various bookmarks but seem to have a somewhat up to date copy on one system with Chrome but Firefox won't even allow me to import the bookmarks as it will just hang.
I have Malwarebytes running on 3 of the systems, it hasn't found anything, I also have Microsoft Security essentials running and did full scans of each system and haven't found anything, there isn't any kind of add on / plug in that I can see that is causing this
Please help as I am now in a huge bind at work without all of my bookmarks!!!

Ok this did not resolve the issue, I downloaded the Places Maintenance Add on and ran it with all of the options selected, I also verified that this is not a permissions issue and ran chkdsk on the disk.
I am unable to make a backup of the bookmarks it just hangs and never makes the backup, I can't even export them either.
I went to the next step and renamed the places.sqlite file and restarted firefox which did restore my bookmarks from a previous backup but I still can't click on the bookmark menu option without firefox locking up .
How do I resolve this and how do I get my data back in to Sync?
If this file is corrupted does that mean that all of my linked browsers downloaded the same corrupt file from Sync? How do I resolve that, is there anyway to recover my history from any of my other PCs?
All that I did was when I was logged out of sync but want to know how I go about getting the info back in to Sync.

Lower priority of a resource hog?

Is there anyway to lower the prioirty of a resource hog?

I am sure you feel better for having a rant, but you haven't provided any information about your system, so no suggestions for help are possible.
I have a 5 year old XP box and iTunes uses 0-2% CPU capacity when laying AAC files. iTunes has always been fairly slow to load but it is faster than Firefox on my system.
You can find old versions of iTunes on FileHippo. The mods don't like us posting the link but it is easy to find.

Playback Skipping Problems with iTunes 7.3 or later - Resource Hog?

Audio playback on my computer was fine on all versions of iTunes upto and including version 7.2. The problem started when Apple released iTunes 7.3 (for the iPhone - which I don't have). Audio playback was fine if iTunes was the only program running. But if I was also using another program - like a simple 3d game or even just using the lasso tool in Photoshop - then playback sk..sk..skipped constantly. So I closed iTunes and tested my music library on Windows Media Player 11 with other programs running and audio playback was consistently good - no skipping at all. But I'd rather not use Windows Media Player if iTunes can work properly! I suspected that iTunes 7.3 had become a resource hog. When iTunes 7.4.2 was released I was hoping that the problem would be solved. It wasn't. So I uninstalled iTunes 7.4.2, re-installed iTunes 7.2 (the last version that worked) and audio playback (with other programs running) is great again. So I don't think the problem has arisen from installing any other programs. My question is : WHAT THE **** HAVE APPLE DONE TO iTUNES since version 7.2?! Please help, because I don't want to be stuck with this version and never be able to update!

anybody?

Firefox version 33.0.0.5397 appears in windows/erdnt/cache how do I remove it

The first scan I ran with Secunia PSI 2 flagged up an old version of Firefox 33.0.0.5397 as out of date and no longer supported and recommended updating or uninstalling. I was unaware I had any old versions of Firefox installed as I am using the latest version 36.0.4 which actually appears further down the list of programmes on the PSI scan. This old version's location is also a bit strange, it appears in a cache within a folder called erdnt in windows. The file path is .... windows\erdnt\cache\firefox.exe. I have looked online for info about this erdnt folder and it seems to be part of a backup programme called ERUNT which I do not seem to have. Very strange. The current version of Firefox 36.0.4 is located in the program files where I would expect to find it.
Can anyone shed some light on this and explain why there appears to be an old version of Firefox in this odd location and if it is OK to remove it and how I go about doing so. Do I just delete or do I need to uninstall it ? What affect any action might have on the current version of Firefox that I am using ?

That is NOT a Firefox version I ever heard of, and the Firefox programs
are stored in the computers Programs Folder.
Open the folder you posted, and rename that file to fffffffffff.exe.
Use most or all of the listed scanners.

I can not delete my history and adding new bookmarks. Upgrading to later Firefox versions and/or re-installing didn't help. The address bar still shows the web addresses of old and whenever I make new bookmarks, it's always gone as if it was never made.

I can not delete my history and adding new bookmarks.
Upgrading to later Firefox versions and/or re-installing didn't rectify it either.
The address bar still shows the web addresses of old and whenever I make new bookmarks, it's always gone as if it was never made.
Also, I have noticed that every once in awhile you can not close tabs you've opened, either by pushing on the X button and/or clicking on the mouse to close it. Although closing the window and opening it again (without closing the Firefox application) seemed to rectify the problem in the short term, it's becoming quite annoying.
== This happened ==
Every time Firefox opened
== the Firefox is being used

I think I have a solution.
First, download the add-on SQManager. This should be included with FireFox, it is really good.
Look for the file '''moz_hosts''' in the folder '''places.sqlite'''.
Don't delete the file, just delete the information in the file. My file has over 3600 websites, which go back years!! I did not know they were there, but I was frustrated about not being able to get rid of them. They popped up every time I used the address bar. Clearing my history would not get rid of them.
This is where they are stored!! I found that by deleting the pesky web site from '''moz_hosts''', it does not appear in my address bar anymore!!!
I think that if I just delete all the websites in moz_hosts....
Wa-la...History Gone!!!
As long as you don't delete the file, just empty it, FireFox won't know the difference. It will just keep adding websites to it until you empty it again.
Why running "clear recent history" doesn't do this, I don't know. You are doing manually what "clear recent history" is not doing.
Please tell me if you see any flaw in this.

The Apple trackpad won't except the "pinch open and close" command on Firefox version 4. It is configured correctly in the system preferences. HELP!

I am using the Apple trackpad with Firefox version 4. The trackpad won't "pinch open and close". It is configured correctly in the system preferences. It also worked in version 3. Anyone have any suggestions?

Do the related browser.gesture prefs on the about:config page still have a value set for those gestures?
Which Firefox function should be performed with those gestures?
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page.

I installed Firefox version 10.0 and now it is absolutely not working. What do I do to fix this?

I upgraded my firefox from 9.01 to 10.0 and now it is completely screwed up. When I click on the Firefox icon I get this message:
Error: Platform version '9.01' is not compatible with
minVersion > = 10.0
maxVersion < = 10.0
I use firefox on a Windows Vista every single day of my life, so for this not to work is a serious problem to me.
I tried completely uninstalling and reinstalling firefox, but that did not work.
Please help me figure this out.
Thank you so much

My firefox version is 3.6.12, however I cannot download any add-ons cause it says I am still using version 2, and it is the same for website such as youtube where it is always saying I am using a outdated browser. How do I solve this?

I keep updating my firefox whenever it prompts me to, and now I am using version 3.6.12, but I still cannot download any add-ons or have problem using youtube cause they still says I am using a older version of the browser.
But when I go Help > About Mozilla Firefox, I am sure I have the latest version and no more updates can be found.

You have or had an extension installed (MegaUpload toolbar) that has changed the user agent from Firefox/3.6.12 to Firefox/2.0.0.13
You can check the general.useragent prefs on the about:config page:
* general.useragent.extra.firefox Firefox/2.0.0.13 MEGAUPLOAD 1.0
You can open the about:config page via the location bar, just like you open a website. 
Filter: general.useragent 
If general.useragent prefs are bold (user set) then you can right-click that pref and choose Reset.

Why DOESN'T Firefox VERSION 6.0.2 warn me when "You are about to close multiple tabs. Do you want to continue"? aka "Confirm Close".

Hello. I have a Windows 7 HP Mini Netbook 32-bit. I just installed Firefox version 6.0.2 (the most updated one). Under
Tools ---> Options ---> Tabs, "Warn me when closing multiple tabs" is checked. However, when I have multiple tabs open and I click on "X" (accidentally one time), it closed Firefox. No warning at all. I tested it again and again (checking the box, unchecking it, then checking it again), and it keeps closing all my tabs without warning.
FYI...I also have a work laptop (Windows XP) and for some reason the "Confirm close" shows up when I try to close multiple tabs.
Thank you.

Firefox does not ask to save tabs and windows on exit

Check and tell if its working.

How do I go back to my previous Firefox version?

I just upgraded Firefox to the newest version available. On the old version, I was able to use McAfee Site Adviser. However, Firefox 4 is not compatible with Site Adviser. I would like to go back to my old Firefox version so I can continue to use it.

Click-hold the unified Back / Forward button, or right-click it to get the Back / Forward history for that tab.
Or install this extension to get the old "drop-marker" button restored.

New firefox installed - didn't give me the option of not installing it before telling me that (essential to me) add-ons were incompatible. How can I get the old firefox version back?

I would not have installed the new firefox if I had known in advance that two of my essential add-ons would no longer work. Now I want the old firefox version back so I can continue to function until the add-ons are updated. Suggestion: when you notify user that add-ons are incompatible, give the option of reverting to an earlier firefox version.

Firefox now always stores the old session, and you can access it by going to the History menu and selecting "Restore Previous Session"
If you want Firefox to display the message to save the session, it can be turned back on by changing some preferences.
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''browser.tabs.warnOnClose''', if its value is set to '''false''', double-click on it to change its value to '''true'''
# Repeat this for these 3 preferences '''browser.warnOnQuit''', '''browser.warnOnRestart''' and '''browser.showQuitWarning'''
If you always open the last set of tabs, an alternative approach is this:
# Click the orange Firefox button, then select options to open the options window
# Go to the General panel
# Change the setting "When Firefox starts" to "Show my windows and tabs from last time"
