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).

  • 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?

    - 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 ...

    You can offer Apple feedback here: http://www.apple.com/feedback/

  • I downloaded Firefox 4.0 and it says to re-install the toolbar but I have not been successful in doing so. Can I go back to the older version? I had no trouble with that and I do not like this new version at all.

    I downloaded Firefox 4.0 and it says to re-install the toolbar but I have not been successful in doing so. I went to the forums and tried all the suggested fixes but none worked. Can I go back to the older version? I had no trouble with that and I do not like this new version at all. I tried a system restore twice and it did not fix the problem.

    I would imagine it's the MyWay Searchbar which is classified by most anti-malware scanners as adware, or even worse as spyware. I say that because I see "SmileyCentral" in your list of plugins and that's an add-on for that particular toolbar. You can disable that via Tools | Add-ons | Plugins.
    There are a number of toolbars which won't work with Firefox 4 anymore due to the enhanced protection mechanisms in the browser.
    Mozilla recommends that you only install add-ons from its own security site @ https://addons.mozilla.org/en-US/firefox/?browse=featured Generally speaking, those have all been tested and approved. The exceptions are those currently under review which are marked with a yellow banner to warn users that they haven't passed Mozilla's labs yet.

  • 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.

  • Firefox 5.0 only has one bookmarks toolbar. How do I go back to the older version that let me have 2 or 3?

    duplicate of https://support.mozilla.com/en-US/questions/844995
    When I downloaded Firefox 5.0, I suddenly had only ONE Bookmarks Toolbar. With the older version, I had 2 and was going to add a 3rd one.
    1 - Can I add additional Bookmark Toolbars to 5.0 and if so, how do I do it?
    2 - If I can't do it, how do I go BACK to the older version? Thank you.

    There is a new extension for that feature. The old extension was abandoned. <br />

    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:<br><br>
    * Fun Web Products Plugin<br><br>
    * My Web Search<br><br>
    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:<br><br>
    #Click '''Help '''| '''Restart with Add-ons disabled'''.<br><br>
    #In the next menu which appears, checkmark: "'''Reset toolbars and Controls'''".<br><br>
    #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.

  • I updated vietmobile remote files app. this app is broken on iOS 5.1.1 I do not have a backup of the previous version of the (paid) app, how can I roll back to the previous version? Is there a repository of previous versions? Am I boned?

    I updated vietmobile remote files app. this app is broken on iOS 5.1.1 I do not have a backup of the previous version of the (paid) app, how can I roll back to the previous version? Is there a repository of previous versions? Am I boned?
    Seems silly to not allow a rollback from a file repository of previous app versions.

    >All apps are tied to the account that downloaded it, so to be able to sync back the previous version you would need to still have your copy of that version
    I'm not sure I follow, I have not sync'd the ipad with my computer. I just saw an update in the app store and took it.
    I tried to del and install the app from the purchased tab in the app store, that reinstalled v2.1 of the app. This also fails to launch.
    I have made two service requests to the developer, no response at this time.
    Is there somewhere I can download and install Remote Files version 2 file? I can only find the new version 2.1 in the app store.

  • I  have been having nothing but trouble with OS 10.6.8.  Many of my appliatins will not work..  HOw can I revert back to a previous version of OS x?

    I  have been having nothing but trouble with OS 10.6.8.  Many of my applications will not work..  HOw can I revert back to a previous version of OS x?

    Before you revert anything try this:
    Reinstall OS X without erasing the drive
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    Next time don't post something like "nothing but trouble." Tell us exactly what the trouble is and provide any additional information such as error messages.

  • 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 <b>about:config</b> page.
    browser.gesture.pinch.in -> <b>cmd_fullZoomReduce</b>
    browser.gesture.pinch.in.shift -> <b>cmd_fullZoomReset</b>
    browser.gesture.pinch.out -> <b>cmd_fullZoomEnlarge</b>
    browser.gesture.pinch.out.shift -> <b>cmd_fullZoomReset</b>
    browser.gesture.pinch.latched -> <b>false</b>
    To open the <i>about:config</i> page, type <b>about:config</b> in the location (address) bar and press the "<i>Enter</i>" key, just like you type the url of a website to open a website.<br />
    If you see a warning then you can confirm that you want to access that page.<br />
    You can use the Filter bar at to top of the about:config page to locate a pref more easily.

  • I updated to new ios and now it is not syncing properly.  How can i revert back to the previous installed version?

    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.
    Try:
