  • Can I run 2 versions of firefox? I need to run older version for one application

    My operating system is mac 10.6.8 and I need to be able to run firefox 3.6.19 for one application & the latest version of firefox for other applications. Can I have 2 versions of firefox on my computer and choose which one to run depending on my application?

    You can install the portable Firefox 3.6.19 version to access websites that do not work with Firefox 5+.

  • 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.

  • Heeeelp!!! I ve just intalled the new version of Firefox and it wont open , my mac is a G5 running 10.4.9 what can I do??

    The fire fox icon is crossed and wont open it just says it cannot be launched and marks -10661 I think I have to reinstall the previous version but I cant find it nor I know how to uninstall the firefox I have now.

    Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
    If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html

  • After their recent upgrade Facebook no longer works for Firefox version 2.0.0.20, what is the most recent version of Firefox that will function with a Mac G3 running OS 10.3.9?

    Facebook (FB) recently restructured their website. After logging on to my FB homepage, some of the graphics are garbled and I am no longer able to post status updates, comment on friend's status updates or pictures, or post pictures using Firefox version 2.0.0.20. I would like to know if there is a newer version of Firefox that will function with a Mac G3 Blue and White desktop running OS 10.3.9 which will be compatible with the new FB? I would upgrade my computer, but have 22+ years of business and tax records that will not function with the newer Mac OS.

  • Can i have 2 versions of Firefox on my Mac at the same time?

    I currently have Mac OS-10.6.8. I currently use Firefox 30. However, my new financial company specifies FireFox 18 to use its website. Thus, can I use both versions on the same Mac. Thanks for any advice that can be provided.

  • 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.

    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.

    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 want to submit a grant application at Pepsi refresh, however they recommend Firefox 3, 3.5 or 4 - not 3.6, which is what I'm using on my Mac 10.4.11. Can I download another version of Firefox so I can apply for this grant?

    If you want to add a new user-agent into User Agent Switcher, you go into preferences > New. Most of the blanks are filled in already, so just change the Mozilla revision number that will be at the end of the User Agent line. To fake 3.5.19, just change rv:1.9.2.19 to rv:1.9.1.19. For the description, put in "Firefox 3.5.19".

  • I is it possible to dowload the new version of Firefox and keep 3.6.28 as well ? How would I do that?

    I have Firefox 3.6.28 and like it. I want to download the newest version because some sites aren't going to be supporting the old one. I want to keep 3.6.28 and not have the new one replace it. Can I download the new one without replacing 3.6.28 so I have both?

  • Can I run OS 10.6.x in Paralleles installed on a Mac running OS 10.7.2?

    Can I run OS 10.6.x in Paralleles installed on a Mac running OS 10.7.2?
    This question is related to my need to continuing using Quicken 2005, which is not supported by OS 10 7.2.  If I could load Mac OS 10.6.8 into Parallels and run Quicken 2006 in an emulated version of Mac OS, I could then run 10.7.2 and move onto iCloud.  I've looked at a couple of altehrnaftves to Quicken 2005 but none are as comprehensive as Quicken.

    Hi John,
    That is an interesting question, to which I don't know the answer. You might try it on a separate drive or partition and see how it works. I run Snow and Lion but on separate partitions on my internal HDD. If you try it please let us know how it works.
