Why is my computer now slower, with Firefox 4, then it was with previous version? It stops and crashes constantly. How can I go back to the previous version?

When I am on Facebook or playing a game, it will freeze and I have to hit control alt delete, to get any response. Within a couple more seconds the same problem occurs. I did not have this problem with the previous version.

I tried so hard with FF4 but no deal. It was considerably MUCH slower than 3.6. Every page just had a 2~3 second wait before it loaded up. This was tested on a brand new Windows 7 64-bit install machine too.
Flash ran much more cpu intensive as well. I played many flash based games in 3.6 and my cpu usage was never always as it was with FF4 in the 90%-100% range.
I had to get rid of it due to the slowness and the lack of older plugin support: ANYCOLOR which I must run and cannot stand the light colored menu pop ups. Also the buttons in FF4 are worse than 3.6. You can't see them when you have a persona applied.
Staying with 3.6 until 4 speeds up or will give 4.1 a try.

Ihave used Firefox for years with great success. But since I updated to Firefox 4.0.1, it has become almost unusable. It is agonizingly slow for me, and crashes constantly. Can I go back to the previous version of Firefox?

I am using windows XP, and have a DSL connection that is not very fast. I think the new version of Firefox may be too complex and have too many things going on for my connection.
The last version worked flawlessly. I had no problems until updating to Firefox 4.0.1, but now I can barely use it.

I updated to new ios and now it is not syncing properly. New songs are not showing up on the ipod display but when I view the device on my computer, they are in the playlist but there is a dashed circle beside the missing songs. It previously synced perfectly before the IOS update. How can i revert back to the previous installed version?

Downgrading the iOS is not supported by Apple.

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.

- it's all said in the title. I can't understand why the developers turn things bad ... risking loosing Apples valuable customers.
More examples needed? (check out the communities and the reviews)
- OSX: Maverick to Yosemite = not recommended (check it out > http://roaringapps.com/apps)
- iPad: older versions as iPad2 should not upgrade to iOS7/8 (it's not supporting its hardware accordingly, it's designed for the latest hardware)
- iTunes (it's possible to rollback to 10.7 - 11.4, but you need to breech OSX system security framework)
- Pages (was a real alternative for many of us, each update reduced features and created incompatibility to older work files)
The list could easily extend to ...

As an update, I installed an update 5.7on my Mac laptop, now the Lightroom 5.0 has become a "Lightroom Mobile" version. How can change it back to the laptop version?

As an update, I installed an update 5.7on my Mac laptop, now the Lightroom 5.0 has become a "Lightroom Mobile" version. How can change it back to the laptop version 5.7?
Thanks for any help you can provide.

LR on your laptop is still a desktop version. It is just now able to upload to the cloud to replicate photos to either http://lightroom.adobe.com/ or an iPad that has LR Mobile installed.
I think you probably just want to change the LR 5 identity plate back so it doesn’t mention LR Mobile all the time. Hover over the identity-plate area, and click on the little triangle that appears, then choose Change Identity Plate.

Recently, I updated to Firefox 4.0.1, and the new version disabled several of my programs, including my anti-virus. How can I go back to the previous version of Firefox?

I want to go back to the previous version of Firefox, because the new version (4.0.1 I think) that I downloaded disabled several of my programs, including my anti-virus program, because they were incompatible with the new version of Firefox. How do I get back to the previous version of Firefox and re-enable the disabled programs?

Some gestures have been removed in Firefox 4.
You can restore the zoom feature by changing the values of the related prefs on the about:config page.
browser.gesture.pinch.in -> cmd_fullZoomReduce
browser.gesture.pinch.in.shift -> cmd_fullZoomReset
browser.gesture.pinch.out -> cmd_fullZoomEnlarge
browser.gesture.pinch.out.shift -> cmd_fullZoomReset
browser.gesture.pinch.latched -> false
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page. 
You can use the Filter bar at to top of the about:config page to locate a pref more easily.

I use the Norton toolbar feature that manages all my passwords. How can I go back to the former version of Firefox since 4 is not compatible?

How can I go back to a former version of Firefox?

Symantec need to update their Firefox add-ons so that they are compatible with Firefox 4. They have indicated that for Norton 360 they plan to release an update to Norton 360 to support Firefox 4 in early May - http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20100720113635EN&ln=en_US
I do not know about the time scale for updates for other Norton products. Pending the update by Symantec, if you want to use the Norton add-ons you will need to downgrade to Firefox 3.6.
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.
For details of how to find your profile folder see https://support.mozilla.com/kb/Profiles

How can I go back to the prior version? I'm having trouble with an IBM tool with the latest version.

How do I go back to the version prior to this one?

You can download Firefox 3.6 by [http://www.mozilla.com/en-US/firefox/all.html clicking here.]

I downloaded Firefox 4.0 and now it takes forever to load most websites. I have a old computer and I probably should not have upgraded Firefox. How can I go back to the older version?

I downloaded Firefox 4.0 and now I am having problems. Everything is running very, very slow. My computer is old and probably does not have the capacity to fun 4.0 effectively. I would like to return to older Firefox 3.
How can I do this.

You're trying to go through a proxy which isn't working. Assuming you don't normally use a proxy to connect to the internet, do this:
Tools, options, advanced, connection settings, set no proxy.
Causes for this may include anything which monitors or forwards newtork traffic on your computer (tools like fiddler2 or tor). It may also be that you are on a network which requires a proxy to access the intenet (some corporate and university networks do this).

Before I upgraded to FireFox 4 fireftp worked with all sites. Now it does not how can I go back to the previous version?

I use Fireftp to deliver information to my customer's ftp site. Earlier this morning I delivered data just fine. After going to FireFox 4 and Fireftp 1.99.2, Fireftp takes me to the ftp site logon, logs on to the site just fine and when I try to change directories Fireftp logs me back on. I know the site is working as I can access everything using RinoSoft Serv-U but is limits file size to 2 mb. Fireftp up until the upgrade worked great and allowed me to load files much larger than this.

I Use IBM Lotus iNotes 8.5.2 Build 401.3. My iNotes also had same problem when I upgrade my FireFox to Version 4.0. The Interface would display the following message on the top of the screen in Red, "A problem has occurred which may have caused the current operation to fail".
I clicked on Preferences, in Basic Settings, under "For all list-type views:", I changed "Show all documents as a scrollable list" to "Show documents one page at a time (faster load time)". Saved and closed and that allowed me to view my Emails one page at a time.

Ever since upgrading to Firefox 4, my webpages load much much slower. How can I go back to the previous version of Firefox and keep my bookmarks, etc.?

I don't have any details. The Question explains it all. We just upgraded from 1.5 Mbps to 18 Mbps download speed and webpages opened really quick until I downloaded and installed Firefox 4. I have Internet Explorer 9, but I do not use it. I would just like to go back to the most current previous version of Firefox and keep my settings and bookmarks to see if webpages still load as slow as they are loading now. If so, then it's not the browser and I'll have to troubleshoot.

You can download Firefox 3.6 from this page:
http://www.mozilla.com/firefox/all-older
However, I'm not sure of the best procedure for removing Firefox 4. You might want to search these forums a bit for advice so you don't lose Bookmarks and other settings.

When we installed Firefox 4.0, found it is not compatible with Trend Micro. How can I go back to the older version of Firefox until Trend builds a compatible version??

On add-ons manager, I see that Trend Micro NSC Firefox Extention 6.5.0.1234 is not compatible with Firefox 4.0.1. I have contacted Trend and been told that their builders have not yet created a product that is compatible. I think this means that I should revert to an older version of Firefox until my internet security is updated. How do I do this? I'm clueless. :) Or, is there a better solution?
