If I don't use the default homepage I have to start Firefox twice. I have all add-ons and extentions disabled.

I have tried setting my homepage to Google and to Bing but Firefox closes as soon as the page loads. Starting it a second time works with no problems.

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 make any changes on the Safe mode start window.

You can try to reset Firefox.
*https://support.mozilla.org/kb/reset-firefox-easily-fix-most-problems
Reset creates a new profile and tries to import some settings from the old profile leaving the old profile intact.
*https://support.mozilla.org/kb/Recovering+important+data+from+an+old+profile
Also check the settings in your security software.
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.

Anytime I run a Flash game, Firefox closes! I have updated all add-ons and extentions, disabled Adobe DLM and went through the suggestions to fix this issue. NOTHING WORKS! What do I do?

The game I am trying to play is on Facebook. The internet and other sites work as normal, but when I load a flash game the game begins for about 30 seconds and then freezes and firefox shuts down. I have used INTERNET EXPLORER and the games loads fine. This issue is with firefox plugins, extensions, add-ons...or whatever. I don't know what to do to get this to work properly.

Thank you so much, for once in my computer life I knew what the problem was, what caused it, why it was caused, what it did, what it made it do and most importantly how to fix it and to do it correctly and expeditiously. I can not Thank You all enough for all of the help! I also have Pogo mailed this to all on my friends list, where they have all learned as I have and have fixed theirs also. and the message is being spread. Thank You again, I just can not say it enough.

I want to use the speed dial extension when I start firefox. I have the option checked in speed dial settings but firefox does not open to the speed dial. How do I get this to work?

I want firefox to open up to the speed dial add-on so I can use it as my start page. In the speed dial options I have checked the option to start firefox in the speed dial but when I open firefox it doesn't open the speed dial.

Sorry, I don't use that add-on, and I don't see a SpeedDial support forum listed on the download page. 
Here is the SpeedDial homepage.

I have disabled all add ons and extensions to stop adverts but everytime I log into my pc the adverts appear again? not happy :(

since I updated firefox I have been HOUNDED by adverts. I read an article that suggested disabling all add ons and extensions but they seem to enable themselves again after I open my pc! I am very careful and always tick and untick boxes when I am downloading updating anything to ensure this doesn't happen therefore these add ons seem to have been automatically added by firefox during the update. not cool! the amount of adverts and the fact I have never suffered from such a pop up invasion in my life is becoming EXTREMELY annoying how do i permanently stop these adverts?

Do a malware check with some malware scanning programs on the Windows computer. 
Please scan with all programs because each program detects different malware.

Every time I start up Firefox, it always prompts me to reisntall the same pile of add-ons and extentions; I install them; still happens; why?

Regarding Firefox 16.0.2. Every time I start up Firefox, especially after a period with my comp in standby mode, I am always asked to install several add-ons and extentions. Always the same ones, and always several. I install them, again and again, yet I am still always prompted to reinstall every time I start Firefox. I've always had this batch installed, but I don't know why it keeps telling me to reinstall them.

Some security software has virtualization or sandbox features that may cause problems by protecting and restoring files in the Firefox profile folder.
It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
*https://support.mozilla.org/kb/Profiles
New files will be created when required.
See "Corrupt extension files":
*http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
*https://support.mozilla.org/kb/Unable+to+install+add-ons
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to check if there is a compatibility update available.
If this hasn't helped then also try to delete the addons.sqlite file.
If you do not keep changes after a restart then also see:

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History") or via the about:permissions page.
Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks, cookies, passwords, cache, history, and exceptions, so be cautious and if you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.
You can't recover from this 'forget' unless you have a backup of the involved files.
It doesn't have any lasting effect, so if you revisit such a 'forgotten' website then data from that website will be saved once again.

I love firefox 3.08 but when I install any improved versions they will not run on my desktop even when I have disabled all add ons and the firewall, can you help?

my system is Windows XP Media Center 2005 Hp model
I use Avast anti virus but have disabled it when loading firefox
I removed the Mcfee firewall which I thought might have stopped it running
I disabled all the add ons in case that was the problem
The internet explorer which I dont use as a browser has loaded up the inbox which ss very hard to remove
I have tried all the suggestions in the support section without success
please help as the message on the screen reads that the firefox version 3.08 is no longer secure.

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!

Firefox keeps wanting to start in Safe Mode and it says I can make some changes permanent such as "Disable all add-ons" and others. When I select one of the options I can then "Make Changes and Restart".

When I make my selection it can then proceed to use Firefox. However the next time I open Firefox I get the same problem.
I'm using Windows 7. I have used Firefox for many years with Windows XP and never had this problem. Is there a solution?

See [[Firefox is stuck in Safe Mode]]
"Reset all user preferences to Firefox defaults" on the [[Safe mode]] start window.
Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the "Find Updates" button (in Firefox 4: right-click the extension -> "Find Updates") to do a compatibility check.

All addons , plugins and extentions disabled on boot up. I have deleted the proflie folder and started from blank and if I add 1 addon on plugin it starts again

This has become a total Joke. I have read every post I can find on here with this problem and None have worked. I wiped the profile folder and made a new one. With no addons or plugins or extentions Im fine. But if I add any ,and I have tried many different ones just to test they are disabled. Whats the fix ? Im ready to go back to IE.
Happens with FF11 10 9 etc etc plus I have NO add on Toolbars..

You mention problems with Firefox 9, 10, and 11. Have you used these versions one at a time over a number of weeks as they update (or are you trying to run all these at the same time ? ).
I am guessing you may have bookmarks and possibly passwords etc that you may wish to retain. First of all backup your profile, and your bookmarks (they are also in the profile) put them somewhere safe outside the Firefox program and profile paths ( Win 7 Desktop is a suitable location ) see
* [[backing up your information]]
* [[backing up and installing Firefox]]
* I am assuming one user and only one version of Firefox do not proceed further if that is incorrect
* you may want to ensure you have bookmarked any add-ons you need
# (after creating the backups)Use IE to download the installer file for the current Firefox release from http://www.mozilla.org/en-US/firefox/all.html
# Uninstall Firefox, use the Win7 Control Panel,
#* accept the delete personal information option
#* restart the computer, check Firefox has gone, and that the profile folders are also deleted
# run the installer file to reinstall Firefox ( ? May need to disable security software )
# check Firefox Works
# install add-ons one at a time, checking each one works

Why, after disabling all add-ons to correct a problem with Norton, am I unable to re-install Adobe Acrobat 10.0.0.396, even though all 7 applications in the "Containing Folder" are enabled?

mynortonaccount.com web page began coming up whenever I would go on line. Norton email support gave me steps to follow using my Firefox browser, in the safe mode, to disable all add-ons and reset user preferences to Firefox defaults.
Since then, although trying about 15 times, I have been unable to reinstall Adobe Acrobat 10.0.0.396 so that it functions.
From the "Re-initializing the plugins database" article, and progressing to the "Open Containing Folder," but unable to select File and Exit menu, I did locate "Adobe Acrobat" version 10.0.0.396
which showed all seven applications "enabled." This problem is with Firefox only. Internet Explorer functions normally.

If you want adobe acrobat pdf files to open in firefox you need an acrobat plugin, have you checked that is installed and enabled.

With Firefox 18.0.1, the browsers continues to crash. I have tried all alternatives from turning off all add-ons to resetting the browsers. What next?

With any one solution, it appears fixed but then begins to crash again. It crashes at start-up. It crashes as I move from one page to another. It crashes after being on for several minutes or sometimes for better part of an hour. It has little to do with video retrieval or any one page or speed of changing from one to another page. It has gotten worse and worse with each new upgrade and seems to have started with upgrades after 14.0. I have to believe the problem is embedded in Firefox rather than any of the suggested solutions put out by Mozilla. At present, I have all add-ons and plug-ins disabled. I am prepared to uninstall Flash and Java if that would help. I prefer Firefox but it seems Mozilla does not appreciate the frustration of not have someone, other than me, solve this problem. Any suggestions? Thanks.

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

Ignore this question, I've now solved it.

Can't open a new tab in version 30.0 on my mac. I have no add-ons and use the default settings.

I tried removing any extensions (only had one), and am already using the default page settings. This occurred RIGHT after I upgraded to the newest version- 30.0. I don't have any add-ons either. So since this happened with your newest version and seems like a ton of people are having the same problem, it says to me that FIREFOX needs to find the cause, not lay it on us to figure a round-a-bout.
Also , I've had a problem that the tabs keeping reloading a ton of OLD tabs every time I restart or open a new window. The same ones, like 30 of them! Tried deleting cache, didn't work. ?

Query don't use the right index when using bind variables

Hi people !
I need some help because I have an issue with a query that don t use the right Indexes as it should
First of all, I have mainly three tables :
ORDER : Table that contains description for each Order (approximately 1 000 000 Records)
ORDER_MVTS : Table that contains the tasks made (called movements) to set up each Orders
with quantity of packages prepared for each product (approximately 10 000 000 Records)
PRODUCT : Tables that contains the products (approximately 50 000 Records)
When I launch the query with hard coded values, it brings back response very fast
because it uses the right index (ORDER_DHR_VALID) which represent the date and hour of the order
(with format 'DD/MM/YYYY HH24:MI:SS'). The selectivity for this index is good.
NB 1: I have to use the trick " >= Trunc(date) and < trunc(date) +1 " to filter on a simple date because
the index contains hour and minutes (I know it wasn't probably a bright idea at conception time).
NB 2: The index on ORDER_MVTS.PRODUCT_CODE is'nt discriminating enough because there is'nt enough different products.
It's the same for index on CUSTOMER_CODE and on MVT_TYPE so only the index on ORDER.DHR_VALID is good.
Here is the correct explain plan when I execute the query with hard coded values :
SELECT SUM(ORDER_MVTS.NB_PACKAGE)
FROM ORDER_MVTS, PRODUCT, ORDER
WHERE ORDER.DHR_VALID >= TRUNC(to_date('14/11/2008 10:04:56','DD/MM/YYYY HH24:MI:SS'))
AND ORDER.DHR_VALID < TRUNC(to_date('14/11/2008 10:04:56','DD/MM/YYYY HH24:MI:SS')) + 1
AND ORDER_MVTS.MVT_TYPE = 'DELIVERY'
AND PRODUCT.CODE = ORDER_MVTS.PRODUCT_CODE
AND ORDER_MVTS.ORDER_CODE = ORDER.CODE
AND ORDER.CUSTOMER_CODE = 'ADIDAS'
AND PRODUCT.CODE = 1234
Rows Row Source Operation
1 SORT AGGREGATE
2 NESTED LOOPS
4 NESTED LOOPS
2 INDEX UNIQUE SCAN (object id 378548) --> PRODUCT_PK
4 TABLE ACCESS BY INDEX ROWID ORDER
777 INDEX RANGE SCAN (object id 378119) --> ORDER_DHR_VALID
2 TABLE ACCESS BY INDEX ROWID ORDER_MVTS
30 INDEX RANGE SCAN (object id 377784) --> ORDER_MVTS_ORDER_FK
Now the problem is when the query is used in a Cursor with bind variables.
It seems like Oracle don't use index on ORDER.DHR_VALID because he can't figure out that he have
to actually filter on a short period of time (only one day).
So Oracle uses the index on ORDER_MVTS.PRODUCT_CODE which is'nt a bright idea (it takes 10 secondes instead of just one)
Here is the bad explain plan :
Rows Row Source Operation
1 SORT AGGREGATE
2 NESTED LOOPS
722 NESTED LOOPS
2 INDEX UNIQUE SCAN (object id 378548) --> PRODUCT_PK
722 TABLE ACCESS BY INDEX ROWID ORDER_MVTS
1790 INDEX RANGE SCAN (object id 377777) --> ORDER_MVTS_PRODUCT_FK
2 TABLE ACCESS BY INDEX ROWID ORDER
1442 INDEX UNIQUE SCAN (object id 378439) --> ORDER_PK
Now I have found two solutions to this problem :
1) using a Hint to force the use of index on ORDER.DHR_VALID (with /*+ INDEX(ORDER ORDER_DHR_VALID) */ )
2) Using Dynamic SQL and keeping the date hard coded (but not the other values except mvt_type)
For example :
QUERY :=
'SELECT SUM(ORDER_MVTS.NB_PACKAGE)
FROM ORDER_MVTS, PRODUCT, ORDER
WHERE ORDER.DHR_VALID >= TRUNC(TO_DATE('''||To_char(P_DTE_VAL,'DD/MM/YYYY')||''',''DD/MM/YYYY'')) '||
AND ORDER.DHR_VALID < TRUNC(TO_DATE('''||To_char(P_DTE_VAL,'DD/MM/YYYY')||''',''DD/MM/YYYY'')) + 1 '||
AND ORDER_MVTS.MVT_TYPE = 'DELIVERY'
AND PRODUCT.CODE = ORDER_MVTS.PRODUCT_CODE
AND ORDER_MVTS.ORDER_CODE = ORDER.CODE
AND ORDER.CUSTOMER_CODE = :CUSTOMER
AND PRODUCT.CODE = :CODE ';
These two solutions work but Number 1 is bad in theory because it uses a Hint
and Number 2 may be difficult to code.
So my question is : Does someone knows another solution to force the use of index ORDER_DHR_VALID that can be simple and reliable.
Thank you very much for support

What version of oracle you have? CBO work is different in 9i and 10g.
Usually cost based optimizer do not want to use index for >< condition with binding variables because optimizer can not use statistic to determine selectivity, and by default selectivity of <> operators is low.
(As I remember '>' selectivity by default is 5%, you have two conditions > and <, therefore resulting selectivity will be 0.05*0.05=0.0025 as two independent events, but selectivity of other conditions
ORDER_MVTS.MVT_TYPE = 'DELIVERY' or ORDER.CUSTOMER_CODE = 'ADIDAS' looks much better for CBO)
The best solution I see is do not use binding variables. Actually your query looks as searching query, which executes not so often, therefore you will not have perfomance win along of skipping execution plan creation.
