I installed Firefox 4.0 and now my LastPass form filler doesn't work. How do I reinstall the old version of firefox?

I want to go back to the old versions of Firefox where everything worked. I fill in a lot of online forms and need my LastPass form filler to work. I regret that I downloaded the new version today.

Download the latest version of LastPass here: https://lastpass.com/misc_download.php It works with Firefox 4...

You can force 5.0 "compatibility" with the "[https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/ Compatibility Reporter]" extension, or with [http://kb.mozillazine.org/Extensions.checkCompatibility extensions.checkCompatibility] using about:addons.
For those that really need an earlier version of Firefox
* ftp://ftp.mozilla.org/pub/firefox/releases/
:or with the latest of version 3
* http://www.mozilla.com/firefox/all-older.html
When reinstalling Firefox from a download, Firefox must be down once the installation starts. When the installation finishes, don't let the install start firefox for you. Instead end the install and start Firefox in your normal manner, thus preventing creating a new profile which does not have your bookmarks cookies, etc (but your old profile would still be around and would).

After updating to Firefox 5.0 I can't open Adobe pdf's on websites and in the preferences for Firefox it states it's incompatible. If this is the case how can I get the old version of Firefox back?

I can't open pdf adobe reader files from websites since updating to 5.0. If it truly is incompatible with the update then I need to know how to go back to the older version of Firefox so I can access these files.

Sorry you are having problems. First of all try Fifrefox's safemode.
*[[Troubleshoot Firefox issues using Safe Mode]]
If that works post back for further advice.
Next step, if safe mode did not work.
First: Try a clean install, (you have had a none standard version installed previously) that involves deleting the program files. Then if necessary try troubleshooting by creating and using a clean empty Firefox profile.
See
* this recent post [/questions/940399#answer-377134]
* http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Clean_reinstall
Second: try a New Profile
*http://kb.mozillazine.org/Profile_Manager#Creating_a_new_profile
* this will be an additional profile, it is still worth backing up any existing or currently working profile on a regular basis
**[[Back up and restore information in Firefox profiles]]
* Until you are absolutely confident about the repercussions I suggest
** always use an empty folder when creating a new profile
** never delete or rename profiles, just disable or remove shortcuts
** after creating a new test profile open it and check for any addons or plugins that may be have been included by default

New firefox doesn't work, how do I get the old one back?

From the email newsletter, I downloaded the new firefox. I said yes when asked if I wanted to replace the one that was there. I then found out that my computer's operating system will not work with the new firefox, and my old one is gone. How do I get the previous version back?

-> Firefox 4 versions and later do not run on a PowerPC Mac.
* Firefox 4 and later require at least OS X 10.5 and an Intel Mac.
* http://www.mozilla.com/firefox/7.0.1/system-requirements/
-> Firefox 3.6.23 (Mac OS X 10.4 and later) can be found here:
* http://www.mozilla.com/en-US/firefox/all-older.html
-> For an unofficial Firefox 4 compatible version (TenFourFox) that runs on PowerPC Macs with OS X 10.4.11 or OS X 10.5.8 you can look at:

Firefox 4 is too uncomfortable for mouse operations, menues are too tiny, how can I reinstall the older version 3.6 ? in German or English

firefox 3.6 is much more convenient for me, than version 4. I want to get it back, but how?
Look at the little firefox-button on the topside left (red button) , where are the comfortable menues to konfigurate the browser, to handle all menues easily ?
I urgently want to reinstall the precious version again!!!

Some coupon sites aren't compatible with Firefox 4 so I can't print needed coupons. How can I revert to the old version of Firefox?

When I try to print coupons at coupons.com and target.com, just to name two, I get a message saying they "We're unable to support coupon printing on your system at this time. The Coupon Print Activator is supported on Windows Operating Systems 2000, ME, XP, Vista and Windows 7 when used with Internet Explorer 6.x, 7.x and 8.x, Firefox 2.x and 3.x, Google Chrome 3.x and Apple Safari 4.x and on Apple Mac OS X and above when used with Safari 2.x and 3.x or Firefox 2.x and 3.x browsers."
Does this mean I need to revert to the previous version of Firefox?

Make Firefox 4/5 look like Firefox 3.6.x:
*NOTE: Support for Firefox 3.6.x is scheduled to end soon, so we can help you find solutions for using Firefox 5.
**Also Firefox 4 support has ended (replaced by Firefox 5) and Firefox 6 is scheduled for release next week

I recommend backing up your Firefox settings in case something goes wrong during the uninstall/reinstall process. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
In the Control Panel, Add/Remove programs, look for '''Mozilla Firefox'''. Make sure to save (do not delete) your personal settings when uninstalling.
If it isn't there, just try installing 3.6.23, which is the latest in the 3.6 family. You can download 3.6.23 here: http://www.mozilla.com/firefox/all-older
With respect to version 7.0.1, are you saying that the installation failed, or it seemed to work but it's nowhere to be found?

I had the old version of Firefox, but when offered to download the new version of Firefox, I did so. After the download and the old version being gone, my system informs me that my computer is too old to support the new Firefox. Now I have no Firefox.

I just want the old version of Firefox back.

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
Mozilla are working to prevent Mac users with non-compatible systems from getting the notification about Firefox 4, and also not displaying the "Download Firefox 4" button on http://www.mozilla.com
For the full system requirements see http://www.mozilla.com/en-US/firefox/system-requirements.html

Using the older version of firefox is not recommended.

Still, you want to restore the older version, download from the below link

I just updated my pages and now it won't load. This is on my iPad. The first version which has the latest version it can have 5.1 or something like that. I am trying to open a document and am worried that if I uninstall and reinstall I will lose all my documents

I just uninstalled it and am waiting for it to reinstall. I sincerely hope that I have not lost everything that I worked on so hard. Now that mobile me is gone, I have not been able to go between devices to transfer things. I was merely trying to take a document I had worked on and open it in pages, but it said my version was too old. When I updated, it wouldn't load. Now I cannot do anything. I hope that the reinstall fixes it without losing everything. Please advise!!! Yes, I am in panic mode.

Welcome to Apple Support Communities
There are two Applications folders: /Applications (in the root level of the hard drive) and ~/Applications (in your user folder).
If you have a look at the bottom part of the screenshot, you can see where Chess is stored, and it indicates that it's stored in /Applications, so you are looking for applications in the wrong folder.
Open a Finder window, go to Finder menu (on the menu bar) > Preferences > Sidebar, and mark Applications. Then, close the Preferences window and you will be able to access to the Applications folder in the Finder sidebar. Another option would be to go to View menu (on the menu bar) and type:
/Applications
