Default theme incompatible with latest firefox version

I had a Firefox 29 installation on one of my laptops and I copied the profile folder to backup to a different laptop. The other laptop though had Firefox 12 on it so I just updated it, and although my newer add-ons from the backup are now compatible, I can't use the default theme. Instead it has this very basic theme that isn't the default. If I look in the appearance tab it says "Default is incompatible with Firefox 30.0." The theme is labeled "Default 29.0.1". How can I get it to install the default theme for the current version? Thanks.

You can try to delete the compatibility.ini file and check for issues with the files that stores the prefs.
Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.
*http://kb.mozillazine.org/Preferences_not_saved
*http://kb.mozillazine.org/Resetting_preferences
Do a clean reinstall and delete the Firefox program before (re)installing a fresh copy of the current Firefox release.
*Download the full Firefox installer and save the file to the desktop http://www.mozilla.org/en-US/firefox/all.html
If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
*Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*It is important to delete the Firefox program to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

Is norton 360 ready with SafeWeb for the latest firefox version?

Some time ago I received a warning to wait with installing a firefox update because parts of Norton 360 - I think it was SafeWeb - wouldn't work. I received later a notification from Norton that Norton was now in line with Firefox. Am I going to have the same problem with Norton 360 again if I will update to the latest Firefox version?

Yes Norton 360 v5 is fully compatible with Firefox 9, See

After downloading and installing 3.6.11 latest Firefox version, cannot conect to the web. Found old 3.0 version, re-install, back on the internet. What was wrong?

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.

Latest Firefox version has display problems

Hello guys,
There is a major issue with the latest Firefox version for Android.
most of the times it displyas half-black web pages.
This is not related to a specific website.
also sometimes, when i click links, they are not responding. actually, in older versions, at least when you click a link, it vibrates and make sound.
please fix these issues. firefox was great. why did you ruin it with these updates. they were unecessary.
regards
Bulbul

I am running Mac OS X 10.6.8. And I am currently running firefox 5.0.1. What is the latest firefox version I should be running on my mac?

If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the DMG file to the desktop
* Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Trash the current Firefox application to do a clean (re-)install
* Install the new version that you have downloaded
Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data.

Adobe acrobat add ons does not work with latest firefox

I have been using firefox because of my adobe acrobat add ons.. I alwasy convert pages to adobe pdf using my acrobat. It works with firefox 4.0 but it does not work anymore with latest firefox.
Can you help me with this?

Maybe if you read about privacy, policy and sharing of data you'd change your mind. But it was reported that it appeared to work if you used something like the "Add-ons Compatibility Reporter".
You can force 5.0 "compatibility" with the "[https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/ Add-on Compatibility Reporter]" extension, or with [http://kb.mozillazine.org/Extensions.checkCompatibility extensions.checkCompatibility] using about:addons.

Why can't I use Roboform2go with any Firefox version above 3.6.22?

Dear Support;
I love Firefox and I love Roboform2go. But now I can't use Roboform2go (with all the many passwords I have stored on Roboform2go) with any Firefox version above 3.6.22. Why not??? Also now McAfee SiteAdvisor doesn't work with Firefox 3.6.22.

Firefox says to update to 6.0 but roboform will not work. Should I update to firefox 6.0 or not?

Correct the spelling of search on your link to
:https://addons.mozilla.org/en-US/firefox/advancedsearch
:and it would appear that the search would work, use the little dropdown underneath the big green arrow to actually pull up the advanced search you asked for, and it appears to work, I didn't actually bring up any of the results.

My company software has some incompatibility with newer Firefox versions. They require me to downgrade to version 8. Where can I find the installer for v8?

Why o why does my cimputer say uopdayte now to latest Firefox Version and then say add ons like SKYPE etc will not work with new version . I di not understand .o

as above

Many add-ons work only with a particular range of Firefox versions. After the upgrade, Firefox will attempt to find new compatible versions. This is not always possible.
To determine whether an add-on you can't live without has a version for Firefox 11, you can check the [https://addons.mozilla.org/en-US/firefox/ Add-ons site] or try this add-on to make that a little easier (I haven't tried it myself): [https://addons.mozilla.org/en-US/firefox/addon/is-it-compatible/ Is It Compatible? :: Add-ons for Firefox].
By the way, many recent posts report problems with Skype add-ons, so you might want to research here if you notice any strange copy/paste problems.

Can't open my Verizon page with latest Firefox update. Advise?

Trying to open my Verizon page (ID and password required) I end up at a page with text all out of alignment and it won't let me enter my ID or password. Then sometimes it sends me to a page that says the problem is with my Browser and that I need to remove my Mac firewall which I won't do. Rather change my cell company or use another method to get my daily usage over the phone. Can you give me some advice. Thanks.

Hello,
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, and the profile folder containing bookmarks, history, etc. will NOT be deleted.
#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!
Thank you.

Do a malware check with some malware scanning programs on the Windows computer. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of their databases before doing a scan.
