Running two versions of Firefox?

Some web-based applications that I use will not work properly with Firefox 3, but will work with Firefox 2. Can I have both versions of Firefox on my iMac and select between them, or will they interfere with each other? Would it help if I put one on my external hard drive and run it from there (if that is possible)?

you can have two versions of FF but you can't run them both from the same account as they will interfere with each other.
You can make a new user account and run FF3 from your main account and FF2 from the new account.

no, that would make no difference at all.

  • I seem to be running two versions of firefox at the same time help!

    I seem to be running an older version and a new version of firefox at the same time. I run the new version from startup (it forgets previous tabs from last session) and this sadly does not let me use back and forward arrow buttons so its a bit useless. Strangely when I pop an email window up, the older version of firefox appears with the last few tabs I had browsed.
    disabling plugins stops browser starting in new version and back and forward arrows work ok.
    any help much appreciated!

    You can install them both but there are a few steps to take.
    When you install Firefox 4 use the custom installation option and choose a different location to install Firefox.
    In order to use both versions, you need to create a new profile for Firefox 4 (Firefox stores user data in the profile). Using the same profile with different versions can cause problems. Once you create a new profile you can copy certain data such as bookmarks and passwords between them. You can also use Firefox Sync to keep the profiles synchronized. Finally, you will need to set up shortcuts to launch the correct profile for each version.

  • I have opened two versions of Firefox (v3.6.18 and v3.5), v3.6.18 is my default browser. The problem comes after an attempt to open a HTML file.

    I have opened two versions of Firefox (v3.6.18 and v3.5), v3.6.18 is my default browser. The problem comes after an attempt to open a HTML file. An error appears: "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." Why wouldn't it just open on my default browser? Thanks for the help!

    A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, maybe 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.

    Can I have two versions of firefox? i.e. one for work and one for home use. I use Windows xp
    I would like to start fresh with a new firefox for my work only so I can keep my work related bookmarks etc separate from my at home browsing.

    Yes - are you wanting to run 2 profiles on the same machine? See https://support.mozilla.com/en-US/kb/Managing-profiles on how to create a new profile. You then just choose which profile you want to use each time you open Firefox.

  • Can I have two versions of firefox at the same time?

    Hi,
    Probably a dumb question but can I have two versions of Firefox on my system at the same time?
    The reason is because of Add Ons that are not compatible with v4. I'd like to be able to close v4 when I need to use an Add On in v3.
    Thanks.

    Yes, there is: on two separate computers.
    You cannot run two versions of Dreamweaver simultaneously on
    the same
    computer. They can coexist side by side, but the operating
    system will
    not let you run them together.

  • Can I have two versions of firefox - latest and the older 3.6, which I can only use with Blackboard?

    My 8 new Firefox is fine. But I am using the Blackboard online LMS, which has not yet been upgraded for the newer Firefox. I was told Blackboard works fine with the 3.6 firefox. Hence I want to know if I can have both versions of firefox at once on my Windows 7 laptop PC. Or can I only have one version at a time.

    Yes - you can either use a portable version of Firefox 3.6 or you can run two profiles. If you search on how to run 2 profiles there are instructions out there.

  • Running two versions of java, is it possible?

    Hi everyone, I've got two applications, both incorporate applets, but one uses 1.3 and the other uses 1.4. Im stuck as I need to run these two programs at the same time. The reason I cant just use 1.3 is because one uses JTree's which were introduced in 1.4 (am I correct?) . SO if thats the case, is there anyway to use two versions of java on the same machine.????????????
    Thank you
    Graham

    I've got two applications, both incorporate appletsYou have two applets.
    one uses 1.3 and the other uses 1.4. One requires at least 1.4 (you think)
    I need to run these two programs at the same time.
    The reason I cant just use 1.3 is because one uses JTree's which were introduced in 1.4 (am I correct?) .The 1.3 API Spec includes JTree
    So if thats the case, is there anyway to use two versions of java on the same machine?Why can't you just use 1.4

  • Is it possible to run dual versions of firefox?

    there are add ons and features i need from a previous version of firefox, but firefox 4 also has quite a few nifty add ons as well. is it possible to run dual sessions of firefox using different version? boot from usb hasnt worked (well, ok, it worked, but it started as ff4...), maybe theres something else i can try?

    Yes, see ...
    Using multiple profiles - Firefox - MozillaZine Knowledge Base
    http://kb.mozillazine.org/Using_multiple_profiles_-_Firefox
    But from what you indicate they might still be good extensions where it is simply a matter of the maxVersion not being updated. First check the following...
    Go to the add-ons web page at addons.mozilla.com then find your add-on then check to see if what is there is compatible and if it is the same version as you are trying to use. Also go down to the bottom of your add-on's page and click on the "View all Versions" to see if there is something pending for your version of Firefox listed as "Experimental".
    Check the developer and user comments to see if there is a solution.

  • How can I run both versions of Firefox at the same time?

    Alright, so I decided to install the Firefox 4 beta 3 as a test sort of thing. But now it's set as the default browser, and, no matter what I do, I can't switch back to the old one! I can't use any of my old add-ons now!

    If you are want to test pre-release versions of Fiefox it is best to use a different profile for each version, and then create shortcuts to launch Firefox using the correct profile for each version. Firefox store user data in profiles, pre-release versions of Firefox can make changes to the profile that cause it not to work in older versions of Firefox.

  • Have been up for 2 days trying to have two versions of Firefox on the same machine because Princeton Review only supports 2.0 and my laptop upgraded me to 4.o can you please help?

    When I try to access the interactive sites on Princeton Review I politely receive this message:
    Your browser: Firefox 4.0 WinNT | JavaScript supported: Yes | screen size: 1366 X 768 | Flash Version Installed: 10.0 r42 | Supports AJAX:Yes | Click here to test connection speed
    Attention:
    '''This browser is not supported. '''Links to Start, Resume or Start Over any exams in iTest are disabled for this browser.
    '''''We encourage you to use''''' Microsoft Internet Explorer 6.0 or higher or '''''Mozilla Firefox 1.5 or 2. '''''
    ''Use of your Online Student Center in Firefox 3.0 is not yet supported.''

    IMO, you are better off installing - [http://sourceforge.net/projects/portableapps/files/Mozilla%20Firefox%2C%20P.E.%20Legacy/Mozilla%20Firefox%2C%20Portable%20Edition%202.0.0.20%20Repack/FirefoxPortableLegacy20_2.0.0.20_English.paf.exe/download Firefox Portable 2.0.0.20] - to your hard drive for the few web sites that are so out of date that they don't support newer versions of Firefox. That way you don't need to fool around with a separate Profile for 2.0.0.20, and there is less chance of a another version / Profile of Firefox getting "contaminated" by that old version or you losing private data if your get the Profiles switched.
