Hey I was wondering, me and my brother use the computer but it's boring having to log off and on every time we use the computer so I was wondering if there's a way to create separate profiles on firefox with the settings of each one of us, something like when you open firefox it will ask you which profile you want to use, his or mine. thanks in advance
VG
^^ Yes. You can. Firefox comes with a built-in profile manager. Just execute following command in RUN:
For 64-bit:
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -p
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -profilemanager
For 32-bit:
"C:\Program Files\Mozilla Firefox\firefox.exe" -p
"C:\Program Files\Mozilla Firefox\firefox.exe" -profilemanager
It'll allow you to create multiple profiles.

Starting with the new version 20, you cannot have Personas if you choose "Always use private browsing mode" in Preferences/Privacy/History. This is progress?
Alex
I don't know why, but my flash plugin hangs only in FF :( frustrated
joske
Not all that happy with the new version. I used the firefox download manager incl the auto-shutdown add-on for extra long downloads. That option not possible anymore. Bummer
Mahesh

VG
^^ Yes.

Hey VG it's me again, something's happening with my firefox, everytime I try to open an HTML file it launches an error it says class not registered, that only happens when I try to open it by right-clicking it, but it works when I use Ctrl+O and it also works if I use another browser, the thing is, I like firefox so I would like to use it that way, do you know something about that?
VG
^^ Try to reinstall Firefox first.
Jules Leeb
I am an avid user Firefox, but unfortunately I'm having a major problem in that I cannot open any links from my outlook email.
I receive the "class not registered" error.
I followed the instructions completely deleted Firefox on program files and reinstalled with exactly the same result.
Under the circumstances, I unfortunately cannot continue to use Firefox as my default browser.
Your assistance would be appreciated
VG
^^ Try to make Firefox as default web browser using Control Panel -> Default programs -> Set program access and computer defaults. Manually select Firefox as default browser.

Hi VG, I have a question about Firefox v20 update. I have been using v19.0.2 for a couple months. I didn't like that change since I lost my Shine Bright Skin and other features and had Flash issues. It took at least an hour to get most of everything working the way I like it. Over the last few days I have been getting these notices to install the latest Firefox v20 and I have been closing these notices - I do not want it! I thought I had the automatic update turned off, but apparently not. Because after walking away from my computer and coming back, I saw the box that Firefox had just download the latest version. So, when Firefox is restarted, I will have the latest version - that I do not want! So - I have not restarted Firefox yet. Usually, I leave my computer running all the time and do not shut Firefox down. There is an "updated" folder under Mozilla Firefox in the Programs Folder with today's date. Can I just delete it, so the update does not occur the next time I restart Firefox?? I have already updated my spare computer to V20 and hate it! So, I don't have the time to continue messing with these changes. I HATE the new "Download" changes. I keep multiple multiple tabs open and do not like the fix to change downloads to tabs. Don't want to go hunting for it. I like my Download page the way it is. So, can I delete that "updated" folder? Thanks so much!
VG
^^ Simply open Firefox Options, go to Advanced -> Update and select "Never check for updates" option. It'll permanently disable automatic update feature of Firefox and it'll never automatic download and install new updates.
Dee
I did not make my point very well. V20 has already been downloaded and will be installed the next time I restart Firefox. That is why I mentioned the "updated" folder that is under Mozilla Firefox in my Programs folder. The "updated" folder has the date that these updates were download to install V20. All other files/folders has a different date. That is why I was thinking I could just delete this folder so the updates do not happen. So, V20 has already been downloaded...I want to stop it from taking effect once I restart Firefox! I will change my Options to "never check for updates", but I also do not want these new updates to V20 to occur. Is deleting the "updated" folder what I need to do? Thanks!

Somehow this new version still hangs (no responding) for long time after PC wakes up from sleep/hibernation. The installed FF does not have any plug-in activated. OS is Windows 7 Pro 64 bit. Hardware configuration: Intel i5 3 GHz, 8 GB RAM.
It does come back alive after a minute or two.
Thanks.

I see the new version of Firefox, 21.0, has been released, with the same problem of the last 6 versions. Freezes up for 30 seconds while it transfers to your mail program.
Here's how to fix it: Uninstall the Firefox browser from your add/remove programs in the control panel
Install the Google Chrome browser.
That will fix it for good, even when Firefox 83.0 comes out!

@Bobby Woontz
