Firefox 技術支援討論區

Yesterday my firefox updated to version 96.0. It changed to screen to dark theme. I prefer the light theme and need help to change it back. Thanks

Email me at [email]@Hotmail.com.

I was following this article https://support.mozilla.org/en-US/kb/run-firefox-chromeos

Installed flatpak and repositories but when I try to use flatpak to install firefox I get "No remote refs found similar to ‘firefox’".

I have tried following a few other ways to get it installed, such as using sudo and using sudo su but that has not worked at all.

I followed to flatpak quick setup on Chromebook guide that is linked in the above help article and created the nested containers in crosh as well.

below is what happens if I go to flathub and copy-paste their recommended command to install firefox.

Remote ‘flathub’ found in multiple installations:

  1) system
  2) user

Which do you want to use (0 to abort)? [0-2]: 2 error: Nothing matches org.mozilla.firefox in remote flathub

I need to transfer saved logins from Firefox on a soon to be retired laptop to Firefox on a new laptop. New laptop has a few logins created while setting it up than I copied manually knowing that when I import from the old laptop with many logins, the few on the new laptop will be overwritten. My problem is that Firefox can export logins into a logins.csv file but it seems can only import from a Microsoft browser. Is copying the key4.db and logins.json from the old to the new the only correct way to do this? The old laptops logins.json file has a recent date but the key4.db has a 2018 date even though some new logins were saved last month. Do I only need to copy the logins.json file?

Hello community, would anyone kindly help me with this issue I'm facing? How do I export Logins and Passwords on Firefox running 78.10.1esr (64-bit) on a Mac. The export funtion is not available here and I know the this option is only available on 79 and after, but I'm using a mid 2012 Mac Pro running 78.10.1esr. Is there any way I could still export the logins?

Thank you kindly.

I reinstalled Firefox and now need to import passwords from file where they were exported before reinstall. This article https://support.mozilla.org/en-US/kb/import-login-data-file explains how to import passwords from file, but this option is missing. The only option available is Import from another browser.

From here https://bugzilla.mozilla.org/show_bug.cgi?id=1702336 it looks like the feature was disabled 9 months ago. It is not clear what is the workaround in interim and what is the current state of resolution. For example, how do I use passwords CSV file to load into Microsoft Edge or Chrome and then import this data from that browser back to FireFox?

When i click on the firefox icon in linux apps on my chromebook, firefox does not start. When I try to re-install from terminal, it says it is already installed.

Hi, I had to erase all of my data in order to set up a fresh operating system on my computer. I made a firefox account and synced all my data before wiping my computer. I want to restore my previous sessions I was using before erasing all of my data, however can't figure out how. Thanks.

Windows 10 - Lenovo Thinkpad X1 Carbon This fall after an update attempt, Firefox started trying to update every time it was started. Deleted Update files in Program Data. FF would restart normally one time. Update data files were always replaced and the update on every startup continued - over and over and over. Tried refreshing FF- same thing. Uninstalled FF this AM and tried to reinstall when I get the following error:

XULRunner Error: Platform version "94.0.2" is not compatible with minVersion >= 94.0.1 maxVersion <= 94.0.1

No FF - HELP!

I am trying to update but it just shows this all the time. I do not want to reset my browser because of all settings and stuff I would have to setup it all again I am afraid.

to upgrade my firefox browser from 32 bit to 64 bit, I was following the mozilla instructions to download the 64 bit version, but then uninstall the 32 bit version before installing the 64 bit version. However, using the microsoft store to obtain the 64 bit version, it didn't just download it, it installed the 64 bit version. Now I have both. Should I merely remove 32 bit, and my profile file will be accessed to complete the set up of the 64 bit version? Don't want to loose bookmarks, passwords, etc. by removing 32 bit version.

Late last week, something changed in Firefox browser. I used to download csv files and Firefox would open them with the option to save as an excel file. Now it does not. I have to save it as csv then convert it to excel. It also doesn't seem to save my settings on the website I'm downloading from - I always have to manipulate the settings before downloading. It is a huge headache and I have resorted to using Chrome instead.

Every time I try to open Firefox it asks me for permission to install Firefox Software Updater. I then say no and Firefox opens with a notification to update to the latest version. I opted out from updates but the only option available is for the Firefox to ask before updating, there is no option to opt out definitively. Is there any solution to stop notifications and installing attempts?

Thanks in advance

Due to switching to a Linux distro with a slightly older version of Firefox, Firefox is complaining about the profile I copied in. The profile's compatibility.ini file says LastVersion=91.0.20210812023606/20210812023606. The current Firefox version is 90.0.2. Has the structure of the profile changed between these versions? If not, what's the best way to alter compatibility.ini?

I am using Pop OS, which is based off of Ubuntu.

Somehow I did something, and it made the icon disappear for Firefox. I figured I could easily search the internet and find a simple solution.

I temporarily fixed it last night, but here it is missing again.

I could upload a picture, but I don't see what difference that would make. The dock at the bottom has a spot for firefox, but no icon, literally an empty spot, In the application menu it is a blank spot with Firefox worded underneath.

I have uninstalled, reinstalled, purged, deleted the application data in my user folder..

Just annoying. not a huge problem.

Hello,

Please can you tell me how I can click on a word document and for the document to automatically open without having to click the link in my downlaods? See screenshot of the download box that appears in the top right that I have to click to open the word document.

It does it for a PDF document but not for a word document.

Regards, Craig

"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)

My computer crashed and I have to reinstall everything now. I was using Firefox 78 with Mac OS 10.11.6 el capitan. Please provide link to where I can download this version.

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?
