After I downloaded Firefox 4, it said my system cannot run it. How do I get back to an earlier version of Firefox?

My Mac is running OSX10.4.11. Where do I go to download an earlier version of Firefox (before 4.0) that is compatible with my system?

Yeah, Firefox 4 requires Mac OS X 10.5 or later. You can download Firefox 3.6 from [http://www.mozilla.com/en-US/firefox/all-older.html this download page].

A very important site, does not function properly anymore, how can i go back to an earlier version of firefox

Before i downloaded your firefox 8.0.1, I used firefox to 'save as' the ''Unrealized gain/loss page'' from a brokerage account, - for my ongoing historical financial records file (safari doesn't work for this site).
On the Unrealized gain/loss page, there is a '+' symbol (in front of each stock owned) that one needs to 'clic' on (turns to a -) to see the various dates (and financial data) when you purchased different lots of the same stock. (say, ''IBM''; purchased IBM shares on 21-10-'11, 100 shares, @ $147, current price @ $180, gain of $33/share, total gain $3,300 / 10-14-'11 purchased 200 IBM shares, @ $191, current price @ $180, loss of $11/share, total loss $2200 / - and so on for however many individual 'lots' one has of that particular stock. ). This information is very important to me, and now i can not 'save' it.
- So I want to know how I 'fix' this - or - how I can go back to the earlier version, that did work.

To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data.
You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.
To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.

Re sync them from iTunes or re-download them from the App store. You will not be charged again if you download them with the same Apple ID used to purchase them originally.

IS THIS A GAME?
WHAT DETAILS DO YOU NEED?
THE COMPUTER HAS WORKED FINE
WITH THE OLD MOZILLA FIREFOX
FOR YEARS.
NO CHANGES HERE IN ANYTHING ELSE.

Click the Firefox button, go to Add-ons, then Plugins and disable the following: 
* Fun Web Products Plugin 
* My Web Search 
Both of these are adware/spyware and cause performance issues in Firefox.
Next, click the Extensions menu link (above Plugins where you are) and remove the "Ask Toolbar".
If the problem persists, please do the following: 
#Click '''Help '''| '''Restart with Add-ons disabled'''. 
#In the next menu which appears, checkmark: "'''Reset toolbars and Controls'''". 
#Finally, click the button called "'''Make changes and restart'''".
Just in case you weren't aware of it, you can right click the Back or Forward buttons to get a list of sites visited. If you'd like to see the return of the arrow on the Back button, install this add-on: https://addons.mozilla.org/en-US/firefox/addon/backforward-dropmarker/
Last but not least, some of your plugins are seriously out of date which exposes your system to exploits. Please visit the [http://www.mozilla.com/en-US/plugincheck/ Plugins Check] page and update where necessary.

How can i revert back to an earlier version of Firefox? I have had nothing but slow, slow loading eversince I upgraded to4.01.1. I hate this version of Firefox. I hate the toolbar, it's a horrible colour and I can hardly read it.

Ever since I upgraded my Firefox to 4.01.1, everthing loads much, much slower.......I can go make a coffee while the page loads. Sometimes, it is soooooooooo slow, that it times out and I have to start all over again. Even when I sign on and load google, sometimes it takes forever.
I also do not like the toolbar at the top. It's grey and hard to read, what is wrong with white?
Can I revert back to the earlier version of Firefox? It worked much better. I use ancestry.com a lot and they even recommend a 3.??? version of Firefox.
Anything is better, so I don't have to sit and wait and wait and wait.

Thank you, Zenos. I tried rolling back to v31.2.0, since I had not encountered problems prior to December. However, that didn't help. So I followed your valuable suggestion to revert to v24.6; that seems to have done the trick.
I would like to mark this problem as "Solved" -- the rollback seems to have worked. However, since my original post was a complex mix of things, before I do that, should I post the individual problem sets that I had noted (address fields/nicknames problems -- numbers 1-3; default font problem -- number 4; attachment reminder problem -- number 5) as separate issues which have not been solved?
Do you know if these various issues are being worked on? I'm glad to have the temporary fix of rolling back to an earlier version, but I'd like to get back on the current update schedule at some point if and when these problems have been corrected.
Thank you again!

How can I get back to an older version of Firefox? I have an add-on that is not compatible with version 5.0 but I need it !

I have installed Firefox 5.0 but this version does not work with some of my add-ons.
There are no new versions of the add-ons yet.
I want to uninstall Firefox 5.0 and install an older version of Firefox.
How do I do that?

The latest versions of Firefox require at least Mac OS X 10.5 and an Intel processor. You can revert to Firefox 3.6.xx for Mac 10.4 by downloading the installer from http://www.mozilla.org/en-US/firefox/all-older.html

I download iOS 8.2 now my phone would not charged how do I get back to iOS 8.0.i have an iPhone 5s

I download iOS 8.2 now my phone would not charge what do I do to get back to iOS 8 .0 . I have an iPhone 5s and it is hot now .

I had the same problem with my iPad and my Phone. Reset the phone ( Hold down the button on the front while holding the power button until it turns off) Plug in the charge lead and it will come back on charging. (Worked for me) The only way to see it is charging seems to be to look at the battery percentage after a while.

Firefox 7.0.1 is crap. How do I get back to the old version?

Firefox has worked fine for years. Latest upgrade to 7.0.1 will not work 90% of the time on Vista OS desktop. How can I get the old version back?

A possible cause is security software (firewall) 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 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.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

I have Windows Vista and firefox 7 is NOT compatible with it. how do i change back to the earlier version?

Each time I go on any websites, there is always double stacked writing either on the left or right side of my screen. Also, lots of other items have been disabled because of firefox 7 (like Adobe reader etc) and because of those being disabled, i can not play games online anymore. I did not want firefox7 because i was quite happy with the older version, but I have no clue as to how to change it back and how to stop from getting alerts about newer versions of firefox every other day. It is rather annoying.

How do I go back to an earlier version of Firefox?

I've had a belly full of this version. For one thing it doesn't save the tabs when you shut down.
When I try to load a previous version, the thing updates to the latest version without any input from me.

i found the link to earlier version:
