Firefox 技術支援討論區

Using v115.7 in debian 12.

I prefer to open pdf files with the default viewer in the operating system, not on a firefox browser tab. I have gone into settings->general->applications and configured selected "Use system default application" for PDF files. If I click on a pdf file it downloads to my Downloads folder, which is the usual and preferred behaviour. If I click the downloaded files icon on firefox's toolbar, I see the file I downloaded, all good. If I open the folder with all downloaded files, and click on the file, it opens in the OS's default viewer, all good. On the other hand, if I click on the downloaded files icon on firefox's toolbar and simply select the downloaded file from the displayed list, it opens on a firefox browser tab. This is driving me bananas. How do I configure firefox to launch the default system application instead?

The new selection "Copy without site tracking" may eliminate certain codes, but does not remove all invasive data (my term). Consider this common URL occurrence:

link text

The new filter does absolutely nothing to this and when I pass this kind of URL on to others, I do not want to include all that crapola. Currently I have to manually edit the link, which can really get tiresome when passing on a lot of links.

Is there a way to modify anything in Firefox to accommodate this?

For now one week, I cannot sync my browser using Firefox sync. When checking the logs, I always see :

Sync.Resource WARN GET request to https://sync-788-us-west-2.sync.services.mozilla.com/1.5/208380794/info/collections failed: [Exception... "The connection was refused" nsresult: "0x804b000d (NS_ERROR_CONNECTION_REFUSED)" location: "<unknown>" data: no] No traceback available

I have tested on multiples wifi network and mobile data and still the same error. After checking, it seem that this server is down, and I don't know were to report this.

Is this the right place to report this or is it a thing I can do to fix that ?

Thanks

I'm developing a website and noticed while testing that firefox sends requests to "/sw.js" on my local webserver. When starting with a fresh profile folder, this does not happen (and also not with other browsers). So, I thought, this might be one of my extensions, but in Troubleshooting mode, the browser still sends these requests, everytime a site is refreshed. It does not affect performance or anything, I am just afraid that I was somehow hacked as I did not make many settings in firefox. Do you know, how I could further diagnose the problem?

I've looked for solutions, some had weird MTU settings, some needed to enable hardware acceleration in Chrome, but haven't found a solution that works. Created a new profile to try that out, but still no dice.

I can do a test recording in Google Meet, which displays my video just fine, but when playing back, it's just a black screen, and that is also what happens if I share my screen. Participants get a lot of black.

I've been using Firefox with Google meet for many years, and never had this problem before. I did report the issue in Meet, but it's not likely to attract much attention from Google.

Suggestions much appreciated.

Tomorrow I will help a friend update their unsupported Linux OS to the most current version of the OS. The present version of Firefox is 88. Firefox could not update I assume because of the age of the OS.

My concern is porting everything correctly from the old to the new version of Firefox. If I setup sync, will it restore his passwords and add-ons in addition to his bookmarks?

If not is there a good way to do it?

Hello and thank you for your help will my question. I'm using the Firefox Browser 78.7.1esr on my laptop with LinuxMint 17.3 installed. This version of Firefox is the most up to date allowed with my current operating system. Everything is working fine. The laptop sits on my desk at home, connected to a secure internet server. I do all my work online and everything has been working great.

Now I receive messages from Mozilla regarding older Firefox Browser versions, including the 78.1.7esr that will no long support signing in to Firefox or the syncing function. I've never used the sync option, however I totally depend on being able to access the Firefox Browser multiple times each day.

If I am understanding this correctly, after March 31, 2024 I will be effectively locked out of my Firefox Browser installation. Is this true? Do I have any other options beyond an update (which is impossible on my current laptop). Any other ideas?

I assume I need to move to a completely new web browser of some sort, although Firefox is great. Anything you can offer by way of ideas or help is greatly appreciated. Thank you for your time.

When watching a video on YouTube, the sound suddenly stopped playing. Currently, sounds in video and audio are not played on all sites.

The problem is only in the browser. Audio and video files are perfectly reproduced by the VLC player. There is also sound in the Chrome and Firefox ESR browser.

My actions. 1. Disabled all extensions 2. Clearing history and deleting all cookies

My browser - Firefox Developer edition, version 123.0b9 OS - Debian 12

P.S. I have been using the developer edition for many years. It seems to me more convenient and faster compared to regular Firefox. I really don’t want to delete the customized browser.

I need help with audio in browser...

Many thanks!

My bookmarks and most history no longer accessable. They may be gone. I need to know where they are stored so I can make sure they are gone. If they are gone I have other machines which do have bookmarks. I think there is a way to copy the bookmarks from one system to another. Hopefully that information is in the main default-release and I can move a copy to the lacking bookmarks closer to the machine with no bookmarks and import what I need?

I have followed the troubleshooting suggestions with no avail. I am currently in troubleshooting mode with all add-ons disabled. The problem persists. The only way to handle the problem is to depress the scroll wheel on the mouse and start scrolling. However, the problem returns with the next page. The problem shows up on Windows 10 as well as Debian bullseye.

I have used Firefox and Firefox-esr for years on the same platforms. This problem started about six months ago with no resolution. So what has changed? On Win 10 Firefox keeps getting updates whereas Firefox-esr never gets updates. The problem persists on both platforms. More than one mouse has been used with the same results. I have removed Firefox and Firefox-esr and re loaded them, no joy here either.

I fill out a specific online form on a regular basis. When I used Chrome several months ago it always remembered my form data. But no matter what setting I set I cannot get this to work on Firefox.

Under Privacy & Security I've set History to Use custom settings for history: Remember browsing and download history enabled Remember search and form history enabled Clear history when Firefox closes disabled

I have also checked antivirus, antispyware, firewall, and privacy programs are not interfering. I do have a VPN but only use this when using online banking.

My Subject pretty well says it. I'm trying to transfer by syncing my desktop Firefox with the Firefox 124 on a newly installed Kubuntu on a new laptop. I have all these functions synced ON. The recent history but not the long-term history, passwords (thank heavens), and all bookmarks got transferred, but not the open tabs/pages. I've done the desktop sync followed by the laptop sync a few times, still without the tabs' transferring. How do i get those transferred?

I want to see the stats for the video currently playing (resolution, frame rate, etc...)

i've confirmed this setting media.video_stats.enabled is true.

i right click on a video but no option to see stats.

does this exist? i've looked for an extension too but cant find any.

I'm having really odd behavior using Firefox (linux) with Microsoft 365 web apps (outlook, word, excel, etc). Its happening various distros too. Is there a known issue at this time with FF and 365 web apps?

   Excel - cell content deletion on moving through cells.
   Word - line content deletion on hitting carriage return.
   Mail/Cal - Webapp not displaying content on double clicking emails or calendar events.

Found a few sporadic similar reports from users on various forums, but no official note that it was a known bug. Assuming it isn't widespread - anyone here have any anecdotal reports of similar issues. Seems to only affect the linux distro versions of FF.

This renders the web app sites unusable with Firefox so I have had to use another browser for these apps. As these apps are ubiquitous with work and productivity, it's rendering Firefox as a second-choice browser unfortunately. No one really enjoys having to "pick the right browser" for work or play.

Is there any way to resolve these issues? Hoping someone has some insight.

The Amazon.co.uk search plugin was working but now its not and when i try to click "add search engine" a box pops up with

Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml

another post suggested checking the about:config browser.search.region mine says "GB" which would be correct for .co.uk

All other search plugins work fine. Any suggestions?

Ive tried down loading all the required packages; I have the latest FireFox available ;but still get the message on you tube to update to latest Fire Fox. On Ubuntu 18.04the same message but includes a error code 99,999.

I use a VPN connection to access my workplace. This means that all my DNS queries MUST go through the company's VPN tunnel.

Firefox is deliberately blocking my work. The DNS over HTTPS "feature" does not work over this VPN connection.

In Firefox, there was previously the following setting: Preferences > General > Network Settings > Enable DNS over HTTPS

I REALLY NEED to have this setting restored right now.

Hi, I am using Linux Zorin and have updated to a later OS but cannot reinstall my stored files because, "/home/garry/.mozilla/firefox/0czvkt76.default-release/lock". Which has confused me, I have used a Deja Dup backup which uses Duplicity files as per the Zorin programme. Duplicate files are stored in a WD ext hard drive. What can I do to recover my files pls? Appreciate! Cheers, Garry
