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?

I cannot open emails in Hotmail even though I have disabled all add-ons and plugins.

As of this morning, I cannot open any emails in Hotmail or open any folders therin. I have disabled all of my plugins and add-ons which has made no difference. To the best of my knowledge, no updates have been made to Firefox on my PC since yesterday.

When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
(You also can clear Firefox's cache completely using:
orange Firefox button ''or'' Tools menu > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now")
(2) Remove your live.com cookies (save any pending work first) using either of these:
* While viewing a page on the site, right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
Then try reloading the page. Does that help?

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 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!

The back button no longer works. I have disabled all add-ons, rebooted & reset the defaults for the browser and nothing has changed. This happens on all webpages.How do I get the back button to light up again?

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.
*https://support.mozilla.com/kb/Safe+Mode
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
*Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
Another possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

Slow scrolling with all add-ons and extensions disabled, but OK is safe mode

I have a page for work, with a lot of links, that scrolls very slowly, with a choppy action. It is the same with all add-ons and extensions disabled. But when restarted in safe mode, the scrolling is OK.
What else does the safe mode block? Or what could be the problem.

In Firefox 4 and later Safe mode disables extensions and disables hardware acceleration.
*http://kb.mozillazine.org/Safe_mode
Try to disable hardware acceleration.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

I have disable all Add-ons - I've reinstalled FireFox 6 three time and it repeatedly locks up and slide shows fail to load. I have all of the proper Flash and Shockwave type Add-ons. I just can't resolve the problem.

I have tried disabling all Add-ons.
I've reinstalled FireFox 6 three time.
Slide show pics fail to load.
I have all of the proper Flash and Shockwave type Add-ons.
I just can't resolve the problem.
Yet my browser repeatedly locks up

Sending a solution that I have already tried is of no help, but I tried them all again, reloading works sometimes, I have seen in the past that others have had this problem also, of pages not completely loading. So I don't see how you can say I am the only one. When I first started using Firefox it worked great but now it doesn't, one of the updates caused this problem. I guess it's back to IE as it works fine now.

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.

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.

I cannot open my mail in hotmail. I cleared my cache and cookies, I reinstalled firefox, I tried disabling all add-ons and plug ins...nothing works. I don't understand, yesterday it worked just fine. Any help?

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.
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

When I close Firefox, it leaves an open instance each time in Processes. This eats up memory. I've disabled all add-ons, and it still does it.

Over the course of the day, I can have 15-20 instances running in the background and they can range from as low as 3K in memory to upwards of 500000K. This makes my computer super laggy, and I have to go in and manually shut down each one. I've disabled every single add-on and plug in, and tried uninstalling and re-installing Firefox to no avail. I'm at the point where if I can't get this fixed, I'll just have to switch to another browser because this is a huge time suck. If you have any ideas, I'd appreciate it. Thanks.

Use "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit) to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.
If you use "Clear history when Firefox closes" then try to disable this feature.
*Tools > Options > Privacy > Firefox will: "Use custom settings for history": [] "Clear history when Firefox closes"

"Checking Compatability of Add-ons" Update window at each startup & redirects to a welcome page. Tried disabling all add-ons & updates / force compatability checker. Thoughts?

Each time I start Firefox a "Checking Compatibility of Add-ons" update window appears, which redirects me to a welcome to Firefox 5.0 page with my normal home page in another tab. I tried disabling all add-ons and updates as well as the force compatibility checker. I think my AVG safe-search bar might be causing the problem, but I have it disabled and never use it. Please help me get rid of this.

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.

Firefox crashes for 10 seconds when trying to download files, deleting downloads.sqlite, reinstalling firefox, disable all add-ons doesn't solve this problem. Help!

I am having this problem for weeks now.
What I tried:
- Defragmentation
- Reinstall Firefox on a different location
- Change download location
- Start Firefox in safe mode and try download
- Disable all add-ons and plug-ins
- Complete malware/spyware scan
- Complete virus scan
- Delete downloads.sqlite in the profile folder
- Uninstall firefox and delete the entire mozilla folder in Roaming location
- Disabling antivirus
Nothing helps! I'm only having this problem in Firefox. Downloading with Chrome for example doesn't give any problems.
How can I resolve this problem? I'm really desperate.
Thank you in advance!
Yanco

Thanks for your input but I already said that I deleted downloads.sqlite.

My iGoogle homepage is not showing any gadgets but they are there in IE. If I restart with AddOns disabled they are shown. I have disabled all AddOns seperately and it has made no difference.Any ideas?

I found that the culprit was Adblockplus. To solve it : ABP>drop down menu>Report issue on this page>click bullet blocking too much and follow steps.

Why have many of my add-ons and extensions been disabled after switching to firefox 6

Many of my add-ons and extensions have been disabled after switching to Firefox 6.
None of the Java extensions can be used;
my Microsoft frame is disabled;
my media player is gone;
and my google toolbar with all of my important bookmarks is missing.
How can Firefox 6 be considered an "upgrade"?
How can I '''retrieve Firefox 4 or 5'?''--there's no point in using a browser that limits so many necessary add-on sites!

Hi, mhaoo7--
Tried your plugins updating suggestion; no go.
Then tried updating to FF7.
This time the Yahoo! toolbar was no longer compatible with FF.
Scoured sites discussing problems with versions 6 & 7
and decided to retire to version 3.6.19.
Now both Google and Yahoo! toolbars are re-installed and
working....Only deficit may be that FF no longer supports or
soon will not support this version.
I have stashed all of my necessary bookmarks on Google's toolbar;
I like its drop-down menu as it doesn't change the page/window I'm
in the process of using;
I don't want to see that menu listed separately in a new window (too chaotic).
Same for the Google dictionary and Thesaurus, which are straightforward
and easy to use, again requiring nothing more complicated than a drop-down menu
to search for words and concepts.
--I checked Firefox 6 and 7's Dictionary/Thesaurus options but unfortunately
found none.
So if Firefox continues to upgrade with diminished returns, I'll likely have to go
to Google Chrome.
Would rather not do that.
Maybe I can keep FF 3.6.19 without incurring nasty repercussions.
Hope so.
Have enjoyed being with Firefox for a few years.
Thank you for your attention.
