Firefox 技術支援討論區

I was updating Firefox on my on my computer, Mac OS 10.11.6( I know, I know…). Now The current version of FF won’t run and I am unable to upgrade the operating system because it so old. Is there a way to figure out which version of FF I had? Its slightly overwhelming to look at the choices of older versions to download. Any help is appreciated. Been a FF supporter forever and love it!

Hi, I just paid $99.00 for the update to microsoft office on my macbook pro. The download will not open due to the message: "Microsoft_Office_16.67.22111300_Installer.pkg” cannot be opened because it is from an unidentified developer. It cannot verify this app is free from malware."

It is a purchase from the microsoft website. Is there a way to set up firefox to allow opening this installer? Thanks.

Version 102.5.0esr installed. About Firefox indicates it is up to date. Bank website indicates the browser is out of date. Downloaded 107.0.1 and no data such, as bookmarks, was transferred. How do I transfer or import bookmarks, home page, etc. from 102.5.0esr to 107.0.1?

I had an issue with Macbook Pro. Apple support had to wipe and reinstall hard drive. Firefox is my default browser and I was signed in. When we reinstalled Firefox on my new hard drive, I signed in and there's nothing there -- no booksmarks, history toolbar, etc.

Can i still get back that information?

I can no longer use online banking because they require the most recent version of Firefox which they say is 107. When I try to update my computer, it says I have the most up to date version of Firefox which is 102.5.0esr so won't let me update. How do I fix this?

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'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 am really frightened. An Apple support person had me erase my system and reinstall. When i down loaded Firefox none of my bookmarks downloaded. I tried sync now, nothing. Everything, a year of research, gone. What do i do?

L.S., by installing the latest download all my passwords are gone. I ask you urgently to let me now how to undo the latest installation (I believe it was yesterday) . I'm really very disappointed. I do not know all the passwords by heart. Please help me ASAP.

Many thanks and fiendly greetings, Marianne

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.

Hi, I need to install a digital certificate. The instructions I have are... Tools>options>advanced>encryption>view certificates>import but I can't find anything past "tools" Thanks, Katrina

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!!!

MY Windows 11 laptop crashed and OS may need to be reinstalled. Will this wipe out my Firefox browser bookmarks. I would like to save the bookmarks somehow. How do I do this without access to that system?
