When I start FireFox the process with the image name System and user name System (looking in Task Manager) starts taking tremendous CPU time (up to 50% or more).

I am using FireFox 4.0.1 for Windows, and routinely check for updates. It did not do this under previous versions (not sure it is was specific to 4.0.1 or with started with 4.0) I have watched the CPU utilization when starting other applications including Thunderbird, and the high utilization by this process so far seems tied to whenever I start up the newer version of FireFox.

Start your '''Computer''' in safe mode. Then start Firefox. Try '''Safe''' web sites.

Error "Licensing has stopped working" | Mac OS

A web site I used to visit daily, but haven't for a while, causes Firefox to go off in la-la land. I have to kill the process with the task manager.

The web site in question is for our local newspaper. The problem occurs when I am returning from a discussion thread (by Disqus) to the article it's attached to. Also when I attempt to return to the home page from an article. Sometimes just letting it sit for a while will produce the problem. At that point I cannot open a new tab, switch to another open tab, close tabs, click on any menu bar items or close the app. The tab I was in shows the spinning wheel and says connecting. I must use Task Manager to kill the process. I tried installing version 31.0 with no result.

I loaded a jZip programme, now whenever I start Firefox it open with the jZip search page and I can't permanently change the home page to my own selection. How can I get rid of theis iZip home page

I have tried all the optons to change the home page, but when I exit from Firefox and restart, it will revert to the iZip search engine home page. I even deleted the izip search engine reference from the searchplugin directory but with no success

You can open the about:config page via the location bar and do a search for jzip via the Filter at the top of the about:config page. 
You can reset all jzip related prefs via the right-click context menu to their default values.
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. 
You can use the Filter bar at to top of the about:config page to locate a pref more easily.

When I open Firefox, it goes to the first page and then stops, saying "Not Responding" with the cursor spinning. What can I do to fix this? Thanks for any help

When I open Firefox, it goes to the first page I open, but then stops and says "Not Responding" with the mouse cursor spinning. I hit the close button and it says Windows is searching for a solution (which doesn't come).
When I open Firefox again, it says:
Well, this is embarrassing.
Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page.
You can try:
Removing one or more tabs that you think may be causing the problem
Starting an entirely new browsing session
Any ideas? I gretly appreciate any help. Thanks!!

What is that first page?
Can't you open any web pages in Firefox?
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't click the Reset button on the Safe mode start window or otherwise make changes.
*https://support.mozilla.org/kb/Safe+Mode
A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

I just order 8 calendars from iPhoto and they came to me fine. Now I need to order two more but when I go thru the process I get a message saying:unable to assemble calendar. There is a probleme with the photo with the file name"(Null)" more........ .

Would someone be able to explain to me the following issue with Iphoto?
I ordered 8 same calendars for my soccer team and received them fine. Although a couple of pictures on it are a little off (out of focus). I need to order two more of the same calendars but when I go thru the process ireceive an error message saying:
"Unable to to assemble calendar" There is a problem with the photo with the file name "(Null)" The full resolution version of this photo either cannot be located or is corrupt. Please replace this photo or delete it from your calendar.
How can I fine this "corrupt" photo? How did it go thru with the first batch of calendars but won't go thru now?
Thank you for your help.

Apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start
with Option #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

After installing a new version of Firefox, I get the error message "The procedure entry point JS_GetOperationLimit could not be located in the dynamic link library js3250.dll" when I try to start firefox. Elsewhere in the forum a complete reinstall is suggested; however, I can't do that because of my company's IT policies. Is there any way to solve this problem WITHOUT a complete reinstall? Thank you!

If you can't reinstall Firefox yourself then you need to contact your IT department and ask them to check the Firefox installation.
It is possible that some files got broken with the latest update.

Firefox won't start. Everytime I end the process/close the last window, it keeps getting stuck at about 2500k memory in the task manager. The only way I have to fix it is to change some kind of compability settings or try and access it in a new way, and every time it crashes/closed/computer blue screens that setting will no longer work.
That is a short term solution, but eventually I'll run out of ways to access firefox successfully. I've tried many solutions, and some worked, but only once. I have yet to find a permanent solution for this problem.

First please update your plugins to make sure you are up to date. Shockwave Flash player has a newer version 16. In order to better manage the memory that Firefox uses please see these troubleshooting steps: [https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-ram Firefox Uses too much RAM]
You also mentioned that Firefox crashes, we're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.
#Enter ''about:crashes'' in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
#Copy the '''5''' most recent Report IDs that start with '''bp-''' and then go back to your forum question and paste those IDs into the "Post a Reply" box.
''' Note:''' If a recent Report ID does not start with '''bp-''' click on it and select '''Submit'''.
(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

As soon as Firefox opens, it starts increasing memory usage until it maxes out, and it won't actually close unless I end the process in the task manager.

Even if I'm not doing anything, no matter how few tabs I have open, Firefox will slowly increase in memory (RAM) usage until it's using nearly 100% of my computer's RAM, and everything basically freezes. Even when I close the window, the process continues to run, and I have to end the process in the task manager in order to get it to stop using RAM. I've tried disabling all my add-ons, and that does not help.

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

When I start FireFox the process with the image name System and user name System (looking in Task Manager) starts taking tremendous CPU time (up to 50% or more).
