Firefox 3.5.4 is in compatible with my system!

FireFox 3.5.4. is now incompatible with my operating system [Windows XP]; not compatible with Norton 2010 security; have lost all add-ons and plug-ins; and, can not reset, upgrade, or reprogram Mozilla Firefox with 3.5.4 because ops system/security won't let me!

What happened and why can't older Firefox 3.5.3{?} be reinstated? Only way to use internet is by {Qwest}--Internet Explorer or by Mozilla with Google start page. Formerly, Firefox was mated with Yahoo as my default browser. Any attempt to re-establish FireFox is met with security warnings and crashing! What shall I do to be happy computer/FireFox camper again?

My HD is a HP Pavilion 1610 with 250GB Hd; Dual Core 2gb RAM; and, Windows XP connected to a 12mps DSL and WiFi Qwest Modem.

Please Help ASAP! I am desparate to be up-to-speed again! I am not a techno person so please be specific in your details. Thanks.

Re: Firefox 3.5.4.

From their 'system requirements' page:
* Windows 2000
* Windows XP
* Windows Server 2003
* Windows Vista

So it's more likely something is wrong with your copy of XP than with Firefox. I would do a System Restore back to when it still worked. Then maybe try again with Norton 2010 disabled.

And it might make sense to download your own copy of the 3.5.3 install program from and safely store it away.

Have You Tried Uninstalling Firefox 3.5.4 & Re-ins 3.5.3?

In reply to: Firefox 3.5.4 is in compatible with my system!

The download for 3.5.3 should still be available.. Just an example below.

But if 3.5.3 worked on your computer, it's not clear why 3.5.4 doesn't work as well.. It does here on a about 30 computers or so.

EXACT errors would be helpful for figuring out your issue.. And just in case you haven't done so, and because you may have a malware problem, please downloadm, install, update, then run the free malware removal tool from the links below:

If you can't download, install, and run the files below, then on a friend or family member's computer, download the Malwarebytes installer and update files from the links below, copy them to a CD or flash drive, then transfer the files to the problem machine and use them. If you can't start the computer into "normal" windows, try installing, updating, and running the scans AFTER the computer is started into Safe Mode.. I use the sites below to download the installer file and the manual updater:

Once downloaded and before transferring them to the problem machine, rename the program installer "mbam-setup.exe" file to something else like "Gogetum.exe", then copy the installer file and the update file to a CD or flash drive.. Transfer the file to the problem machine, then install the "Gogetum.exe" file, then run the update to get the program current.. After that, run a full system scan and delete anything it finds.

Malwarebytes Installer Download Link (Clicking on the links below will immediately start the download dialogue window.)

Malwarebytes Manual Updater link

Hope this helps.
