After updating to Firefox 8.01 all my add-ons are disabled & I have to manually reinstall those that still work after each reboot??

After updating to Firefox 8.0 & 8.01 all my add-ons were disabled.
I have to reinstall those that still can be enabled manually after each reboot. These, that I can reinstall, are:
Download Helper 4.9.7/WOT 20111107/Adblock 1.3.10/DivX plus Web Player HTML5 2.1.2.145/
All my other add-ons are incompatible with this version of Firefox! This includes Ghostery which I particularly miss,
This is annoying!

Ghostery: Works with Firefox 3.5 - 11.0a1: https://addons.mozilla.org/en-US/firefox/addon/ghostery/
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.

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 do a compatibility check or see if there is a compatibility update available.

I set up firefox sync on two desktops; setting it up on a third fails with "unknown error" after I input the key. All other add-ons are disabled. What should I do?

I followed the same procedure in adding a device for the second and for the third. The second one worked, but not the third.
As far as I know, all software is up to date.

ok.. I tried this three times and kept getting that access denied thing when I clicked post my questions. So now maybe I wont have to typ this a fifth time....
I have a MAC computer with Sync. Was set up under sync Beta. I have an Android phone synced to it that was synced using the pair this device function. It works perfectly. I just got a new Android Tablet and am trying to add it to my sync and it does not seem to have the pair my device function. It insists I log into my sync account. So I try it and it tells me invalid userid/password. I verify and it is the exact email address userid that shows as being my sync account on the MAC. I verify the password on the MAC and it tests out fine. Try the tablet again and invalid.. So I try to reset my password on the tablet and am told my email address/account name does not exist. I just verified it AND Synced my MAC using it!! I have my recovery Key but there is no place to input it into the tablet. There is no place on tablet to enter the link device codes. How can my account be valid and in use on two devices but invalid and nonexistant on the new one? And How do I get the New one to sync with other two?

I can reenable them but FF will disable them on the next startup. I uninstalled version 13 and installed version 12. Problem gone! So I'm still using version 12 and am afraid to update to version 13.
This problem began when I was trying to research and fix a problem (no history all-of-a-sudden) so it probably was something I caused. Can't recall everything I did though.
So: Does the addon problem I described have a solution? If so, I'll update my version 12 to version 13. Please respond.....

Warum sind nach dem Update auf 23.0.1 alle meine Add-Ons verschwunden?

Heute wurde Firefox automatisch auf 23.0.1. aktualisiert. Dabei sind alle meine Add-Ons verschwunden. Das ist bereits das zweite mal, dass bei einem Update alle Add-Ons ohne Spur verloren gehen!!!
Today Firefox updated to 23.0.1. All my Add-Ons are gone. This is the second time, that my Add-Ons disappeared without a trace after the automatic update!!!

Für iTunes war alles in Ordnung, nicht mal ein Fehler wurde ausgegeben!
Mit meinem WLAN klappt die Verbindung seit dem Update nicht mehr. Löschen und neu verbinden hilft nichts.
Mobile Datenübertragung funktioniert ebensowenig. Wenn ein APN eingegeben wird, ist der gleich wieder gelöscht.

I am unable to view flash videos from all websites except youtube after updating to Firefox 4. All help will be appreciated. Thanks in advance :)

Start Firefox in [[Safe Mode]] to check if one of the extensions 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
* [[Troubleshooting extensions and themes]]
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")
In Firefox 4 you can use one of these to start in [[Safe mode]]:
* Help > Restart with Add-ons Disabled
* Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)

Why do I have to force quit firefox? All my plug-ins and add-ons are disabled, and still firefox cannot quit.

Apple Q and Firefox > Quit Firefox do not work. The only thing that works is FORCE QUIT.

If Firefox hangs (stops responding) when you try to clear the cache and cookies and you have already disabled all Extensions and Plugins from the Firefox (Tools) '''Add-ons''' manager, then the problem could be one of the files in your [[Profiles|Firefox profile]]. See [[Firefox hangs]] and try creating a new Places database, by opening the profile folder (via "Help -> [[Using the Troubleshooting Information page|Troubleshooting Information]] -> Show in Finder"), then quitting Firefox, and deleting the file(s) '''places.sqlite''' and '''places.sqlite-journal''' (if it exists).
If that doesn't help:
Try creating a new Firefox profile for testing (this will not remove your existing profile ; you can choose between the two in the Firefox Profile Manager). See [[Managing profiles]] for details. For other ideas, see [[Basic Troubleshooting]].

Every time I turn on my computer and open Firefox all my add ons are open in tabs and I have to enable all of them all the time, how can I fix this?

I'm using Firefox v. 20.0.1 and Windows 7 Home premium 64 bit.

Which security software (firewall, anti-virus) do you have?
It should be necessary to confirm that you want to install third-party extensions. 
This usually indicates that other software is messing with files in the profile folder and is corrupting them. 
This can either be the extensions.sqlite database file or the prefs.js that stores first run prefs (the first is the most likely cause).
Do you have any cleanup software running on a schedule that may be causing this?
Delete the extensions.* files (e.g. extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

When using Firefox, PDFs won't load natively on Mac Mountain Lion (10.8.2), even when all add-ons are disabled. No issue using Firefox on PC

Whenever I click on a web link, do download a PDF form, for example, I get this error message:
"We are sorry, but Adobe Reader is unable to show documents in this browser configuration.
Please use your browser to download this file and open it in Adobe Reader or Adobe Acrobat.
To avoid this message in the future, many browsers provide a way to turn off certain add-ons, and some are able to show this document natively. Please contact your browser vendor for more details."
This problem only manifested recently. I have recently added Adobe CS6, but the problem manifests itself even when this is disabled. Any help much appreciated.

The Adobe Reader plugin may not be working properly on Mac.
* https://support.mozilla.org/kb/pdf-files-are-blank-and-cant-be-downloaded-mac
* https://support.mozilla.org/kb/Opening+PDF+files+within+Firefox
Disable the Adobe Reader plugin in Firefox (Tools > Add-ons > Plugins) and use the external Adobe Reader application or Preview application instead.
PDF files may be found under entries like Portable document or Adobe PDF document.
*Firefox > Preferences > Applications > Adobe PDF document : Use Adobe Reader

Today I have a windows 7 just set up and did not transfer fire fox data .I downloaded firefox again and installed some add ons but I only have a startup screen

I just want a firefox toolbar with all the tabs history,delete,menu,etc: what I have is a getting started page with search bar.

You're using Firefox 29 which is at Beta at the moment and will be released to the public next week. The UI has changed drastically and the Firefox button and menu bar have been hidden in place of the new menu located on the right end side of the navigation bar.
You can restore your menu bar by press the ALT key then at the top go to View > Toolbars > Menu Bar

After updating, my firefox wouldnt open up. So I uninstalled it and was going to reinstall it. But it wont???

not sure what the updates were when i did it. I had to leave. But when i came back later, I tried to open my firefox and got nothing.

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.

After every reboot, all my addons are disabled, I have to manually enable them

The first session I start after a reboot, none of my addons are enabled. After enabling and restarting, they remain enabled for all future sessions until a reboot.
I'm using Windows 7 64 bit.

Uninstalled ZoneAlarm Pro. No change. Uninstall BitDefender. Works perfectly.
