Firefox 技術支援討論區

I have moved from Centos Linux to Rocky Linux and could not play Perron FM on onlineradiobox.com whereas I could on an Ubuntu Linux machine. It turned out I had to install ffmpeg (dnf ffmpeg) on the OS to support the right codec. The error was (in Firefox developer view, F12): HTTP “Content-Type” of “audio/aac” is not supported. Load of media resource https://onlineradiobox.com/json/za/perronfm/play?platform=web failed. Hope this helps someone.

Hi,

While using Firefox just now on Windows 7 as a limited user, it crashed. So far as I'm aware, my version was up to date as of yesterday or so.

When I reopened Firefox after the crash, I checked the About menu item which said that Firefox needed to be restarted to be updated. Doing so disabled the program and I cannot open it.

So I downloaded the installer thinking that I'd have to do a clean install. When I ran "Firefox Installer.exe", it said that Firefox needed to be updated and said it would do that. I have tried that twice now, and both times the updater got about 75% through and just died. I still cannot access Firefox and when I try to run it through the Start/Run menu, I get a message saying that "Windows cannot access the specified device, path, or file. You many not have the appropriate permissions to access the item". I have tried looking in C:\Program Files\Mozilla Firefox and can see firefox.exe, but it will not run and gives me the same "Windows cannot access..." complaint. I tried running it as administrator, and got the same complaint.

I have copied the contents of install.log into the troubleshooting information area below on this page. I tried to copy installation telemetry.json into the same form, but it wouldn't paste into the box and opened a new tab instead.

At this moment, I don't see a way around doing a clean install. That will be a pain in the ass as I had a lot of context open, and would rather not have to reconstruct that, but I see no choice at this moment.

Any suggestions that you have will be greatly appreciated.

While attempting to do a clean install, I started to uninstall Firefox and was given a message saying something like "Firefox must be restarted complete an update." I tried to cancel the uninstall but could see no way of doing so. I closed the control panel item and I restarted my computer. Firefox came back up and now says that it's up to date.

Perhaps the installer really was finished but neglected to tell me a restart of the computer was required. I'm quite certain that no such message was given and Task Manager told me that the installer was no longer running after what appeared to be two failed attempts to update Firefox.

I'm still confused by what happened, but am happy to report I can now drive on (93 minutes later) and my context wasn't lost. ;-)

I uninstalled Mozilla VPN after poor performance. Now Firefox will not connect to the web although other browsers work (Edge). A new tab page loads but without any news, etc. I have uninstalled Firefox and reloaded it several times without effect.

My browser is not reacting (at all) to any website input and I can't even reach the settings page. I just see a blank page and the turning wheel is not loading or reacting. I checked the firewall. No problems there. My other browser is working fine. I reinstalled and freshened up Mozilla firefox.

hi,

Maybe someone had the same problem, I use two security option outside of Firefox: 1. /etc/hosts file, all the site that I do not want to allow my machine to interact with; source: https://github.com/StevenBlack/ 2. VPNs anti tracking scripts

I use a mac, Mac OS 11.6 Firefox 93.0

With all the two security option enabled, Safari works fine, TOR works fine, Firefox has massive issues with loading pages speed. Some of the Firefox settings: Network Settings: the DNS over HTTPS is OFF, as I am using a VPN Privacy and Security: set to standard, but there is no difference is loading speed when switching to strict Extensions: I use 1password, multi account containers and user agent switcher; no difference is loading speed if I disable or remove all extensions

Any idea why is Firefox loading page speed effected?

Many Thanks Michael

If the vertical image is long, scroll down and it will be black and the image will not be visible. Only version 93 has bugs. If you left-click the mouse in the space next to the image, the image will appear again. But if I keep scrolling down, it's just black again.

I've been trying all day to get to Amazon. No go. I've checked here, and found old threads about this problem. I've tried what was suggested in them, but still not able to open Amazon. There was another site that I could not open, also, with the same error message, but I cannot now recall what that site was.

Please help! I need to check on an order from Amazon that I placed just yesterday.

On websites that renders text in the users' installed fonts, the text gets rendered in Arial Narrow. This only happens on Firefox; attached are screenshots of https://nyaa.si/ and https://mpv.io/ on Firefox and in Chromium.

A quick glance at about:config with the search term "font" shows no modified settings.

Any fixes?

This problem started with an update a couple months ago. Each bar is about 4 pixels wide and appears only on the right, left, and bottom edges of the browser window. They persist when the window is full size or smaller, but disappear on f11. The bars are completely unresponsive. Clicking or resizing the window doesn't seem to work inside of them. Even though the top of the window has no visible bar, there is still an unresponsive region like the other three sides and approximately 4 pixels of empty space.

When it comes to color, the bars spend about 50 percent of the time as white and 50 percent as the same gray that Firefox's dark mode uses. I wasn't able to get a screenshot when the bars were gray, but I was able to screenshot the top right and left corners when the bars were white, which I have attached.

It appears as if there are buttons of some sort poking out on the top right and left corners. If I had to guess, the top right icon looks like the "x" button on a Windows 7 window, and the top left icon looks like the red dot in the uppermost corner of a macOS window. My machine has only ever run Windows 10, and Firefox is the only application that this problem occurs in.

Restarting, using troubleshooting mode, manually removing extensions and themes, messing around with compatibility settings, running as administrator, refreshing Firefox, and reinstalling Firefox have all been unsuccessful. It really is annoying to live with this bug.

Firefox will not open saying it can't find the profile. There is a profile in the Application Support folder and old ones on the desktop. I followed the directions to access the profile manager through Terminal, but it didn't work. This Firefox Application is one I restored from Time Machine. I got into this problem when I tried to update Firefox. My MacOS system does not meet the requirements to install the latest Firefox. Apparently, my former Firefox got uninstalled in the effort to install the latest version.

My minimize/maximize buttons have suddenly gone missing. I found other answers on this site that say Tablet Mode is the culprit; indeed, the density settings within Firefox are telling me Tablet Mode on.

However, tablet mode was officially removed in Windows 11. It's not in the settings, it's not in the Control Panel, and registry edits don't seem to work either. So what's going on here? A regression? How do I get my minimize and maximize buttons back?

Hi,

I have scoured the web and can't seem to find a solution to this. Either firefox doesn't support this feature or I haven't looked enough.

How can you identify the pid of a tab in firefox? There isn't a tab in the task manager that shows this, like with chrome, opera, and edge.

I'd appreciate any help.

Thanks

When I attempt to log in to my HomeDepot account I get this error message "We're sorry. There was a temporary technical issue. Please try again later." I have no problems with all other browsers.

Through Firefox I am unable to click on the google tools after searching for something (area with all, images, videos, news, tools, more), I have tried restarting the browser and my computer. I am being forced to use Microsoft Edge in order for it to work.

My online banking access is not available due to ; " this page slowing down Firefox. To speed up your browser, stop this page "

I did that and did not help.

Firefox: 93.0 OS: openSUSE Tumbleweed 20211030 KDE Plasma: 5.23.2 Qt: 5.15.2

Firefox now freezes almost immediately upon launching.

I have performed all the troubleshooting steps described at https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding

I have performed the Refresh procedure and disabled hardware acceleration. I have no themes or add-ons installed.

The freeze is permanent; it doesn't recover. I have to perform a "kill -9" on the firefox process.

When the freeze has occurred, the CPU is not spiked. The "top" command is showing GeckoMain at the top of the list.

Firefox updated yesterday to 94.0 since then I can't access website UKmatch.com the page tries to load but won't

I've scanned for malware and viruses, all clear,disabled firewall and all addons still won't work

I tried it on Firefox 93 and it works OK let Firefox update to 94.0 won't work, the site works on Microsoft Edge

I've been with Firefox since day 1 and have never had a problem like this

Has anyone got any ideas please?
