Greetings everyone,

Firefox is my preferred browser and I really prefer the Firefox Engine over Chromium that most other browsers use.

I want to install a backup browser that runs the Firefox Engine in case my Firefox browser has a problem.

I searched a lot and I thought installing this would be the best option: https://www.mozilla.org/en-US/firefox/developer/

However, I’m worried that installing the Firefox developer edition will change my Firefox installation…

I am currently having problems with my Firefox browser. For example often if I type something into the google search box at the right of the address bar and hit return nothing happens until I go down and select Bing instead of the google setting. Also in hotmail (I am on a desktop) if I go to reply, the original is now ether twice. This does not happen if I use Google browser. But I prefer Firefox as I have used it for years.

My concern is if I delete Firefox and reinstall it, I may lose some of the settings or bookmarks that I have set over the years.

Any suggestions? Please simple as i am old and not computer savvy.

Your help would be so appreciated. I am currently on Firefox 107.0 (64 bit)

Thanks, Anthony

The solution of physically copying the Profiles folder seems to be officially endorsed by Mozilla but when I tried it, FF failed to start up displaying an error message that it could not find my profile and closing. I am trying to set up a new PC for my wife's exclusive use, so the Profiles folder in question was from a shared PC with both of us having our own user accounts. The new PC doesn't have multiple user accounts, so I wondered if this might be something to do with it?

I can provide copies of the two Profiles folders but the original is quite big!

Thanks in advance, Simon

I've been experiencing weird downloads whenever I startup firefox. My antivirus prevents the download, and says that firefox.exe is the application responsible. I will include an image of the antivirus(Kaspersky) report. Deleting and reinstalling firefox seemed to fix the problem, but it returned after sometime; even when I just used youtube on firefox(I've tried this atleast 3 different times now). I am not sure if this is caused by one of my extensions, or if there is something else I've done to cause this. I'd just like to know if there is a way to fix it?

I prefer to update Firefox manually, so in my Firefox settings, I have it set to: "Check for updates but let you choose to install them".

So I sometimes get a message when I launch Firefox saying "Update available. Download the latest version of Firefox." and I click "Dismiss"

Today, I launched Firefox (v107.0), got this update message, and clicked "Dismiss". However, when I go to About Firefox, it says "Firefox is being updated by another instance".

Why is Firefox ignoring my preference?

I am on Firefox version 102. It assures me I am up to date. My credit union insists I must be on version 107 to log in. I was able to download and install version 107, but it gives me a different icon and none of my bookmarks are there. It is like I installed it new rather than upgraded. I have no bookmarks, setting, etc.

So, after years of higher-than-normal security in Firefox (64-bit, Win 7) and accompanying problems in loading some pages, I decided to refresh (hoping to reset and have most/all pages load and display fully).

Well, tried refreshing and didn't see the bookmarks saved. Read about "Old Firefox Data" folder and thought I could retrieve anything I needed later. Deleting and reinstalling Firefox has resulted in the "Your Firefox profile cannot be loaded. It may be missing or inaccessible." windowed message.

Repeated uninstalls and reinstalls failed. Tried copying the "ng0ledtz.default-##########" from the "Old Firefox Data" folder into the C:\Users\username\Appdata\Roaming\Mozilla\Firefox\profiles folder with no success.

Please help.

Dear Support

I have my browser settings under "Downloads" with the box checked "always ask where to save file", but the browser seems to ignore that command, and just downloads any email to the default folder that I entered above for file destination.

I have tried to fix this multiple times.

Thanks.

"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN ```

I have been using Firefox ver. 65.0 for yeas and i'm very happy with it. Except certain sites require me to update, such as Chase.com. I have read about some users saying that they were not happy after updating and wanted to switch back to their old version. 1. how would i be able to switch back to my current version if I find I don't like the most current version? 2. Will the user interface be much different for the current version and is there a way I could just view the current user interface before downloading/installing? 3. After switching to the current version, will my settings, auto loading tabs(for email,etc), pocket list of saved articles and other settings be transferred? Since I have never asked a question before, I have no idea where your response will be found. So i have included my email just in case it is not obvious where to find your response. [email removed from public] thank you very much for any help!!!
