Newest firefox has a bug where it won't install add ons.

I recently upgraded firefox to the newest version. Now every time I get updates or install an add on it says "Please restart for changes to take effect" I select restart Firefox, and it restarts, but then it acts like it was never restarted and says to restart for changes to take effect. Constant loop.

Firefox won't install add-ons even after clean install

Add-on installation fails in one of the following ways:
1. Unexpected installation error -203, or
2. The add-on appears in the "Extensions" tab as "Not compatible with Firefox 3.6.3", even though it is.
Sometimes I get the first error, sometimes the second, but all attempts to install add-ons fail with one of them.
I have tried all the troubleshooting advice in the knowledge bases (e.g. http://kb.mozillazine.org/Unable_to_install_themes_or_extensions_-_Firefox#Unexpected_installation_error_-203) but with no success. I even did a clean reinstall of Firefox in a new directory (as described here: http://kb.mozillazine.org/Uninstalling_Firefox#On_Mac_OS_X) but the problem remains.
What else can I do?

I have the same problem : impossible to install or update extensions; either by download (error -228) or by installing a local file (error -203). This is true for all situations : existing or new Firefox profile, different system users, etc.
I searched the kb, asked Google and so, but no solutions worked. The problem happens on all current versions of Firefox : stable, nightly,32 bits and 64 bits.
File extensions.log contains lines of

I am making heavy use of soft links on my systems : ~/Library/* (temp, cache, preferences, etc) is spread onto several physical volumes, and the filetree is done with soft links. No applications has any problem, except Firefox.

Firefox has stopped working. It won't load any page, saying "The connection has timed out." I uninstalled it and reinstalled it, and still nothing. Any suggestions?

Please see here: [[Error loading web sites#w_interrupted-or-reset-connection|Error loading web sites#w_interrupted-or-reset-connection]]

I followed your help directions on "Corrupt extension files" under "Unable to install add-ons", foolishly deleting the files you told me to. Now firefox won't open. I tried reinstalling firefox but it still won't open. Now what do I do?

I was trying to install the SEOQuake add on. After clicking install Firefox would hang up saying the script had timed out and asking if I want to stop it or continue. Didn't matter which option I chose nothing would happen. The only way to stop it was to close Firefox and restart. Tried restarting the computer. Still wouldn't install. Tried installing the Outwit add on and got the same error leading me to conclude it was a problem with Firefox, not the add on. I found this help page <http://support.mozilla.com/en-US/kb/Unable+to+install+add-ons?s=addons+won't+install&as=s> and did everything it told me to. Finally at the end I got to "Corrupt extension files". I foolishly deleted the files you told me to and now Firefox won't even start! I tried reinstalling Firefox and it still won't start. Tried restarting the computer. I have no idea how to get back to where I was let alone install the add ons I wanted to install. Please help. At this point I'd just be happy to be able to get Firefox working.

See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
Create a new profile as a test to check if your current profile is causing the problems.<br />
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)<br />

I'm using firefox version 6 and for the last three days the add-ons manager page won't load. my question is why won't the add-ons page load? is the server down on your end?

i'm using firefox version 6 and for the last three days the add-ons manager page won't load. my question is why won't the add-ons page load? is the server down on your end?

Click on something below the Get Add-ons menu item on the left side of the Add-ons Manager tab.

I just updated to Firefox 4.0 and how do I change the Add-ons window from opening in a tab (I prefer the old window style)?

After updating to Firefox 4.0, I am unable to get the Add-ons tab (ctrl-shift-A) to open in a separate window like it did in 3.6. Where may I find the option/plugin/addon to be able to do this?

Firefox 4 requires at least OS X 10.5. You can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
Mozilla are working to prevent Mac users with non-compatible systems from getting the notification about Firefox 4, and also not displaying the "Download Firefox 4" button on http://www.mozilla.com

Every time I restart my PC and launch the Firefox it asks to install add-ons I installed earlier.

Hi,
Every time I restart/shut down my PC and start the Firefox it asks me to install add-ons I had before restart/shut down.

Hi,
You should look at the article [http://kb.mozillazine.org/Preferences_not_saved Preferences not saved]. These should give you all the information you need!
If that doesn't work:
# Type about:config in the address bar
# Click ''I'll be careful, I promise'' if prompted
# In the Filter input field type ''startup''
# Double click on startup.homepage_override_url
# Delete the text string and click ''OK''
# Close Firefox and reopen the window to verify that it has worked.
Hopefully this helps!

Help needed with deploying Firefox 3.6.11 to upgrade existing installations including add-ons and plug-ins

Hello, I need to deploy Firefox 3.6.11 to existing installations to upgrade them from the old version. That part is fine, the problem I have is will the silent installation update any non-compatible add-ons or extensions? I will be using SCCM for the deployement part..
I ran the installation manually on a typical machine of which it gave the option of upgrading the existing client. Thats fine but the installation then prompted that 2 currently installed add-ons were not compatible with the new version. It lets you select and then "check" for later versions of those add-ins, actually checks for updates and lets you select and install those too!!
Now, how do you deploy silently with those options I`ve mentioned above??? Cant find any command line parameter that allow for that!
Please Help!

James j,
You have a different problem. Your screenshot shows "The Adobe Flash plugin has crashed".
See [[Plugin crash reports]] and [[The adobe Flash plugin has crashed]]. If you need more help you should [[ask a question|ask a new question]] (start a new thread).

Why si firefox so quick to updatewand make many of my add ons not work

every time firefox has an update different add ons do not work after the update.i use my computer and add ons for about 6 hours per day. the add ons are ESSENTIAL. i am sick and tired of updating then having to go back to a previous version. i used to love firefox now i am beginning to hate it almost as much as chrome and IE

I can understand your frustration. The reason for compatibility checks and the resulting deactivation of your add-ons, however, is the concern for your own safety and robustness of your environment (... you may have had some bad experience in this regard yourself, for instance with Flash crashing now and then).
Go to the page '''Tools > Add-ons ''' and click "Extensions" to open the page with currently installed add-ons. There, you can reactivate disabled add-ons or - what's better in any case - look for updates and/or more recents replacements of your older add-ons.

Installed Add Ons, however ontinue to be prompted to install everytime firefox is launched. How do I make it go away?

We received the screen to install ad block plus 1.3.9 and Garmin Commun 2.9.3.1. Both installed and then we were prompted to restart Firefox. Clicked on the restart firefox button and firefox restarted. Now each time we click Firefox, the same screen appears with a long list of Java stuff. What do we need to do so that this screen doesn't appear?

forget that. do this: Close Firefox -> Start Firefox in Safe Mode by Holding down the SHIFT key while starting Firefox -> Safe Mode window appears -> click "Continue in Safe Mode"
-> Update Firefox to the latest version by going to Help Menu -> About Firefox -> click Check for Updates -> if an updated version is found then download the latest version and install it. After that follow these steps:
-> Update ALL your Firefox Plug-ins https://www.mozilla.com/en-US/plugincheck/
-> go to View Menu -> Toolbars -> unselect All Unwanted toolbars
-> go Tools Menu -> Clear Recent History -> ''Time range to clear: '''select EVERYTHING''''' -> click Details (small arrow) button -> place Checkmarks on ALL Options -> click "Clear Now"
-> go to Tools Menu -> Options -> General -> ''When Firefox starts : '''select "Show My Home Page"''''' -> Type the address of the website which you want to be your HomePage e.g. http:www.google.com -> place Checkmark on "Show the Downloads window when downloading a file" -> select Radio Button option2 "Always ask me where to save files"
-> go to Tools Menu -> Options -> Content -> place Checkmarks on:
1) Block Pop-up windows
2) Load images automatically
3) Enable JavaScript
-> go to Tools Menu -> Options -> Privacy -> History section -> ''Firefox will: '''select "Use custom settings for history"''''' -> Remove Checkmark from "Permanent Private Browsing mode" -> place CHECKMARKS on:
1) Remember my Browsing History
2) Remember Download History
3) Remember Search History
4) Accept Cookies from sites -> select "Exceptions..." button -> Click "Remove All Sites" at the bottom of "Exception - Cookies" window
4a) Accept Third-party Cookies -> under "Keep Until" select "They Expire"
-> REMOVE CHECKMARK from CLEAR HISTORY WHEN FIREFOX CLOSES
-> go to Tools Menu -> Options -> Security -> place Checkmarks on:
1) Warn me when sites try to install add-ons
2) Block reported attack sites
3) Block reported web forgeries
4) Remember Passwords for sites
-> Click OK on Options window
-> click the Favicon (small drop down menu icon) on Firefox SearchBar (its position is on the Right side of the Address Bar) -> click "Manage Search Engines" -> select All Unwanted Search Engines and click Remove -> click OK
-> go to Tools Menu -> Add-ons -> Extensions section -> REMOVE All Unwanted/Suspicious Extensions (Add-ons) -> Restart Firefox
You can enable your Known & Trustworthy Add-ons later. Check and tell if its working.

Where can I find my add ons

In the past, when I opened the Add Ons area, it showed me the ones I've already got. I can't find that at all.
I've tried to load one a couple of times, but I can't tell if it's installed or not. I'm looking for an auto fill add on. I'm using Firefox 6 on a Dell laptop.

Are you not able to open the add-ons manager.
Try using
* Tools -> Add-ons (use keyboard key '''Alt''' first if you need to display the menubar.
* or just key into the location bar '''''about:addons''''' and hit the return key
* or use the three keyboard keys '''Ctrl + Shift + A'''
That should open in a new tab. <br/>Next click on the tab to the left marked '''Extensions''' that should display your installed add-ons with status information about them, and buttons to enable or disable.

Just installed Firefox 4 but when I try to search for add-ons every result fails to find anything or the loading gui just keeps spinning. What should I try to fix this problem?

Glad you seem to have sorted things out.
The warning about the warranty is light hearted, I think at one stage it warned "here be dragons" but also intended to make us think as it warns that making changes may produce problems.

Browser Install Fails, it says "Firefox has stopped working" and it does not install. I cant use your browser.

I had few issues with Mozzilla browser so i uninstalled it completely and tried to re install it again. But when i try to reinstall it , it does not install fully , it breaks half way and says, Firefox has stopped working. I cant install Firefox now. Can you help.

Try this instead:
*Download the full Firefox installer and save the file to the desktop<br>http://www.mozilla.org/en-US/firefox/all.html
*Start the installation with a double-click on the desktop icon
Make sure that your security software isn't causing problems.
Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

Firefox 21.0 on OS X 10.8.4 still has a memory leak that occurs with no Add ons, 1 tab and leads to 3GB of memory usage in 10 minutes.

While using Firefox 21.0 on OS X 10.8.4 with 4GB RAM, Firefox memory usage marches up and up until at 3GB (on my iMac) Firefox hangs and is 100% non-responsive and must be killed with Force Quit. It takes 10 minutes to occur.
No Add Ons
One tab

John99,
Unfortunately, the problem was WORSE in FF 22.0. I regressed to FF21.0 and shut off automatic updates. I may even go back to FF3.6, which is the last one where I didn't see this problem.
Thank you for trying but as a longstanding developer I know that pervasive memory leaks is a sign of a broken development process. Thank you for trying...

After upgrading firefox it gets hung up on checking for compatibility add-ons and won't run

I still can't find an answer on any of the support forums and no one helped me when I asked yesterday, is there anyone that may have a clue as what I can do to fix this?
I updated my fire fox on my MAC OS X to 3.6.6 version of firefox, everything went smooth till I open FireFox then the window firefox update opens up and about 1/3 through the process it gets stuck on Checking Compatibility of Add-ons and doesn't go any further. I have hit cancel and firefox opens but it doesn't open any web sites. I have removed firefox and re-installed and it is still doing the same thing. I have also let it run over night thinking it may just take a while and it never progresses, please advise, I am new to MAC but FireFox is the only browser on my mac that will open one of my business pages, known issue with mac for this company.
