I have lost my passwords, and no longer can save open tabs on exit. I don't have time to wait for a fix.

To revert to the previous secure version which is 3.6.17, please do the following:<br><br>
#Go to [http://www.mozilla.com/en-US/firefox/all-older.html Download Firefox v3.6.17] and download it to the desktop.<br><br>
#Then go to Add/Remove Programs, scroll down to "Mozilla Firefox" and remove it, choosing to keep your bookmarks, customizations etc., (''don't checkmark the box'').<br><br>
#Then reboot and delete the folder called "Mozilla Firefox" at this location: C:\Program Files\Mozilla Firefox<br><br>
#Finally run the installation file you downloaded to the desktop earlier.<br>
Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation.<br><br>
After you complete the installation, please go to the [http://www.mozilla.com/en-US/plugincheck/ Plugins Check] page and update where necessary.

  • Want to restore previous version on firefox since my Norton toolbar is incompatible and can't do it.

    I upgraded to the 4.0 version then discovered my Norton toolbar is incompatible. I have been unable to restore my computer to before the upgrade.

    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.

  • Do I need to uninstall previous version of Firefox before installing new version?

    I am worrried about installing new version (3.6.13 ) since old version (3.0.15) is working o.k. Can you advise?

    When you install a release version of Firefox (current version is 3.6.15), it will by default replace the existing version. There is no need to uninstall the old version first.

  • How to restore previous version of search/results.aspx

    Hi,
    I have search center as sub site. There is no Pages library available for the search center.
    I had customized the OOTB search results page. Now, I need to restore previous version of the results page.
    The url for results page appears as <site collection URL>/search/results.aspx
    Which library contains the results.aspx page and how to restore it to previous version?
    Thanks,
    dhijit

    Hi,
    According to your post, my understanding is that you want to restore previous version of search/results.aspx.
    Per my knowledge, the results.aspx isn’t stored in the library.
    You can open the SharePoint Designer to find the results.aspx under the “All Files” folder.
    There is no version information on the page.
    You need to modify the page to the result which is the same as the previous version.

  • How do i restore the previous version of firefox? I now have firefox 6

    How do i restore the previous version of firefox? I now have firefox 6. AVG Safe Search does not work with 6 and surf the web so much doing research that i need it back. Thanks, Sally

    Using the older version of firefox is not recommended.
    Try the classic theme Restore for Classic firefox Menu's
    *https://addons.mozilla.org/en-US/firefox/addon/classicthemerestorer/
    Still, you want to restore the older version, download from the below link
    *Download Firefox 29 - http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/29.0/mac/
    *Download the English version of Firefox 29 - http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/29.0/mac/en-US/

  • I Beta tested 4.0 RC1 and now can not upgrade to 4.0. Error message is need to reboot to complete prior instalation. Have removed all previous versions of Firefox, rebooted and still same error message.

    I Beta tested up to and including 4.0 RC1 without major problems. However I can not now upgrade to 4.0. Same error message time and again, "need to reboot to complete prior upgrade instalation". I rebooted several times, then tried first removing all previous versions of Firefox using both MS Add/Remove and then iolo System Mechanic, then again downloading 4.0. Even after rebooting same error message. I can not therefore install/use Firefox.

    Do a clean (re-)install:
    * Download a fresh Firefox copy and save the file to the desktop.
    * Firefox 4.0: http://www.mozilla.com/firefox/all.html
    * Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    * Don't remove personal data if you uninstall the current version.
    * It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

  • The new version is not compatible with my digital finger signiture. Will this be fixed? If not, I will need to go back to the previous version of firefox

    My HP laptop has a digital signature for accessing my pages such as email, facebook, etc. Since I updated firefox, this is no longer compatible and does not work. It is very painful, I really want and need to use it. Does this mean I need to downgrade to the previous version of firefox?

    EgisTec, who now provide the HP Simplepass application, have made an update of the scanner software for Firefox 4, for details see https://support.mozilla.com/questions/814397

  • Firefox 5 is apparently incompatible with F-Secure anti-virus; F-Secure repeatedly pops up "Changed Application" messages; How do I restore my previous version of Firefox?

    I just installed Firefox 5. Unfortunately, F-Secure's "Application Control" now repeatedly pops up "Changed Application" messages in an endless string. It will not accept my attempts to "Allow" the new version of Firefox. Since Firefox 5 is not compatible with F-Secure, I must return to my previous version of Firefox. I am very disappointed that you have put me to all this trouble. How do I delete Firefox 5 and return to the previous version of Firefox?

    "F-Secure repeatedly pops up Changed Application"
    So how is this Firefox's fault? Shouldn't you write to F-Secure so they fix that?

  • I upgrade from the previous version to Firefox 4.o, I can no longer connect to my work HTTPS website.

    The site I connect to is my citrix account at work, which needs a certificate. I could connect with the previous version of Firefox (3.6). When I upgraded the browser I got the errors mentioned earlier. I changed the setting for the specific setting from false to true. I still unable to connect and got a different error. Could someone please help! Thanks - Aldo

    If you used the option to delete settings, or whatever it is worded when uninstalling, Firefox will remove all your important data information from profiles for all installed versions of Firefox, and you will then need luck and a file recovery utility to try to restore the information.
    You mentioned files being moved to Trash, I was hoping you may still have the required original files. I use Windows XP, and I realise Macs use different locations for files, but I think the files have the same names.

    Note the last article discusses problems when bookmarks are lost, and some of the possible reasons and solutions. Obviously I do not know what has actually happened in your case, and whether or not you used the delete option I initially mentioned.

  • 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.

  • How do I roll-back to the previous version of Firefox? An auto update occurred and now one of the programs used at the office (ACT! v6.0 SwiftMail) won't run with the browser.

    The office I work in uses a very old version of ACT!, an accounting package. This package has a component called SwiftPage, an antiquated email system that enables us to email from the ACT DB. SwiftPage runs via the web browser.
    Firefox just did an auto update (that I will have to find out how to turn off) and now SwiftPage won't run as it is not compatible.
    Can I "roll-back" my version of Firefox or do I have to uninstall and try to re-install an older version?
    HELP!

    Try loading and using the add-on from this link: https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/
    Many add-ons do in fact work if you force them to run. The procedure to roll-back is given in this article: [[installing previous versions of firefox]]
    Unfortunately the official Firefox policy is that you downgrade to 3.6 which is supported for a while longer, and not the now unsupported Firefox 4. If after installing and running the ''add-on compatibility reporter'' you still have problems there are ways around the official policy.
    I think it is absurd that Firefox 4 may be used by tens of millions of users one day and a few days later those that upgrade to Firefox 5 should be not only told not to use a now unsupported browser, if they need to revert due to problems, but are actually obstructed in attempts to do so.

  • How do you downgrade to a previous version of firefox?

    How do you down grade to a previous version of Firefox on an Android Phone? Current versions of Firefox no longer work with our WIFI network. Starting sometime around version 33 or 34 we started noticing that while using WIFI, Firefox would freeze every minute or two. Basically it would start to load a page then the progress bar would stop about 1/6th of the way across the screen. If you wait several minutes the bar would continue to about 5/6th of the way across the screen and then stop and not continue to load the page. If you turn WIFI off and then back on, Firefox will again work for a minute or two then freeze again. The timing is very specific and is not bound by a number of clicks. It also happens on all websites. The problem is not with the WIFI network because all programs including Chrome and the Android Browser work fine with WIFI. Also previous versions of Firefox work fine with the WIFI. We have the problem across several phone and manufacture types as well as across Android versions. We also did not have the freezing problem during a time of lower WIFI usage. So the problem specifically has to do with using newer versions of Firefox on a busy WIFI network. Because it may take time to fix these issues in Firefox we would like to downgrade to a previous version of Firefox that we know works with our WIFI network.
    Thanks for your help!

    Hi Roland
    Here are the answers to your questions:
    What models of Android tablets and phones are you using?
    Samsung Note 4 (running Android 5.0.1), Samsung Rugby Pro (Running Android 4.1.2), Galaxy S5 Active (running Android 4.4.4) & Kyocera-E6560 (Running Android 4.4.2). There are others, but these are the ones I have access to right now.
    What version of Firefox for Android are you using?
    I started noticing the problem with version 34 on. It could have started with earlier versions but I first noticed it with version 34--we did a large phone upgrade and installed version 34 which was the current version at the time. I just tried 37.02 and am still having the problem.
    As a side note I have an old Samsung note 1 (on Android 3.0.8). It is running Version 17 of Firefox and does not have the same problem.
    Steps to reproduce: What did you do exactly, what happened and what did you expect?
    For instance if I do a Google search trying to research something I type in the search hit and hit go. I then click on a link in the search and let the page load. Look at the page to see if it has the answer I need. Then hit the back button and repeat the process with the next link. After about 1.5 to 2 minutes Firefox starts to load the page then the progress bar freezes about 1/6th of the way across the screen. If you wait several minutes the progress bar generally will continue to about 4/6th or 5/6th of the way across the screen then freeze again. If you turn WIFI off then on again Firefox will work for another 1.5 to 2 minutes and freeze again.
    Same thing happens if you are on a web page clicking through links on the page. The problem occurs on all web pages.
    Also more details on your wifi network would be helpful:
    Hmmm, this is a difficult one--I work at the University of Washington, but not with the IT department that manages the technology infrastructure. So I don’t have a lot of technical details. Basically (among other jobs) I do the phone support for the Campus maintenance division. I support 250 to 300 users. While I do not have a lot of the specifics I will do my best to give you a general idea.
    The best way to think of the UW is a small city. We have about 45,000 students and somewhere between 20,000 to 30,000 staff plus visitors. On any given day we can have 80,000 to 90,000 people on campus all of which are capable of using the WIFI network. So when I say we have a high volume WIFI network it is extremely high volume.
    I noticed the problem with Firefox before and after spring break, but did not have the problem during spring break. WIFI usage would have been way down during this time because there would have been fewer people on campus. So the problem only seems to occur when volumes are very high.
    I had a meeting with a UW-IT rep several months ago and he explained that the 2.4 network was near capacity some places on campus, but the 5.0 network had plenty of bandwidth on it. I think most of the phones I have been using work on the 2.4 network, but the Note 4 works with the 5.0 network also and has the same problem. Additionally all other programs work fine with WIFI so I do not think capacity is the issue.
    Also I know Firefox itself is not the issue because it worked during spring break and it works on the cellular network. So some combo of the high volume network and Firefox seems to be creating the problem. Maybe has to do with how Firefox handles things when capacity is reached or exceeded.
    As another side note I did not have the problem with my home network, but I was only using 2 phones at the time.
    It sounds like you are technical since you have done so much testing. Please file a bug with the steps to reproduce at:
    I have some technical skills, but really I am just good at research. I will do my best with the bug report :)
    As for downgrading (which we DO NOT recommend & support since older versions don't have security fixes!) you can install an old nightly from:
    I will try to work my way back to see if I can figure out what version of Firefox the problem started with.
    Please let me know if you have any ideas or need any additional info.
    Thanks!

  • The college uses, E-bray, to read the E books from the library. The previous version of Firefox worked great with the plugin. When I upgraded to the next version of Firefox now the plugin will not work.

    E-bray is a reader that allows me to easily read the college's Library's selection of electronic media. I am running version 5.0 of Firefox and the other version worked fine. It may have been version 3, I think. I have version 3 in my download. Can I load this version back onto my lap or will this really mess things up?

  • In the previous version of Firefox I could close the window and still have my tabs intact when I reopened it. Why does FF 4 closes all tabs and doesn't give me an option to save them? (And if it does, where do I change the setting?)

    In the previous version of Firefox, before closing a window with tabs still open, it asked if I would like to "save and close", "close all tabs" or "cancel" the operation. FF4 will just alert me that I am closing those tabs and ask me is I want to continue, without giving the option to save my research for a later use.

    Firefox 4 saves the previous session automatically.<br />
    You can use "Firefox > History > Restore Previous Session" to get the previous session.<br />
    There is also a "Restore Previous Session" button on the default <b>about:home</b> Home page.<br />
    Another possibility is to use:
    *Tools > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"
