Firefox 技術支援討論區

The latest update has made it so Firefox opens the download panel every time I download something, a very obnoxious behavior when downloading a lot of files, and I can't find a way to stop that from happening.

[came across another question that brings up the same issue], but that one focuses more on a site presumably changing about:config rather than the issue of the download panel itself.

I would like to save my Firefox profile data into my computer as I would like to transfer the data to a different computer. Is there any solution to how to save it down?

I'm buying a new computer and I'm wondering is there a method/procedure that I can use to transfer the entire FF browser including settings, extensions, bookmarks, and passwords without having to reinstall all those items individually? I know I can save and import bookmarks but what about everything else? I look forward to anyone comments. 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 ```

OS: Fedora 36 Firefox Version: 104.0 (64-bit)

I am using Linux Mint 6.0.3.1 , and my Mozilla Firefox version is 77.0.1 . My Firefox will not update, neither automatically nor when prompted. When I go to all the pages for downloading and installing the newest Firefox, I am always able to download a package, which appears as a folder labeled " firefox-89.0.2.tar.bz2 " but then I cannot install it, it just appears as a folder full of files that will not run. I have tried following the command lines in the terminal that these pages claim will make the new version run, but I always just get a response like "no such command" or "no file exists." Shouldn't there be some relatively simple and reliable path to just get firefox 89 onto my computer?

My old computer crashed but I have access to the entire hard drive on my new laptop. I'd like to restore Firefox on the new laptop exactly as it was on the old laptop (bookmarks, tabs, etc.). All of the help articles talk about restoring from a backup, but I never made a backup since I obviously didn't know my computer was going to crash. Which files do I need to access from old hard drive and move to my new hard drive so that everything looks the same as before? Any help would be appreciated.

I exported my bookmarks from the Brave Browser, selected Bookmarks>Manage Bookmarks>Import and Backup>Import Bookmarks from HTML Then navigated to the HTML file the selected "Open" but noting changed except that a small number of the bookmarks appears under "Recent Bookmarks" when I again select Bookmarks. Each item in this list is repeated according to the number of times I tried to import them.

Does anybody know where the ID: 308046B0AF4A39CB comes from?

If you use a Windows 10 1909 64 Bit and you can find this in the installs.ini and in the profiles.ini of users, if you have a Firefox ESR 64 Bit in Version 78.10.0 installed. The INI-Files looks like this:

Installs.ini: [308046B0AF4A39CB] Default=Profiles/8U9skky2.default-esr Locked=1

Profiles.ini: [Install308046B0AF4A39CB] Default=Profiles/8U9skky2.default-esr Locked=1

[Profile0] Name=default-esr IsRelative=1 Path=Profiles/8U9skky2.default-esr

[General] StartWithLastProfile=0 Version=2

This ID can vary if you have a 32 bit ESR-installation as well and the only place I could find it is in the registry

[HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\TaskBarIDs] C:\Program Files\Mozilla Firefox=308046B0AF4A39CB

But also here it differs sometimes.

I need to know where the ID comes from and if I can rely that if this ID is used, I will always address the Firefox ESR 64 Bit no matter which version.

Downloaded the latest version of firefox. When it was opened and it went through the verification process then to move firefox folder into applications for use we received a notice where the firefox logo had a circle with a line through it (indicating to us that is would not function) then an arrow pointing to the application folder. The firefox version downloaded and opened Firefox 91.8 Oesr.dmg

Any suggestions as to what safe version I could use on a mac mini late2012 operating OS X El Capitan 10.11.6 Which I am told is the latest version that can be used on this machine with the following characteristics: processor 2.3 GHzIntel Corei7 memory 4GB 1600 MHz DDR3 Start up disk el capitan 10.11.4 this is strange since 4 lines above it states OS X El Capitan Version 10.11.6 graphics Intel HD Graphics 4000 1536MB

Your suggestions would be welcome.

Thanks

My old Linux computer died and I have removed the still good SSD from it. I have installed the latest Firefox on my new computer and would like to restore the bookmarks and other saved data to the new computer.

I am running Ubuntu 20.04, the old computer was on Ubuntu 18.04.

Can these things be restored, and if so what do I need to do?

I've been using Firefox ESR for some years. Now I would like to know the best way to use and try the "normal" version of Firefox. Can I install it without uninstall ESR? Or must I do a clean install of Firefox after getting rid of ESR? If this is the case, what must I do to keep my profile, bookmarks, etc?

My computer is OS X Yosemite version 10.10.5.

I have updated with the newest Firefox web browser today. Now I can't open Firefox because my computer is too old for this new version. Because I have totally replaced my old one with this new, I cannot go back..

And actually, I don't know what is the right version for my computer. I think I found some very long list of old versions(https://ftp.mozilla.org/pub/firefox/releases/), I don't know which one is right for me and how to install from there - I tried some of them..

If anyone can post the link of right one for my computer and inform me how to install it from there, I'd really appreciate it..

Than you.
