Firefox 技術支援討論區

My PC froze and had no choice but to reload win 10. After doing so I had the choice to download win 11 for free which I did. When I download Firefox all of my bookmarks were missing. I have tried to follow your instructions to retrieve them i.e. Troubleshooting... Application Basics ... Profile Folder...Open Folder... which opened >>> C:\Users\AppData\Roaming\Mozilla\Firefox\Profiles\42o9xo83.default-release . Sadly, I am not a Teckie and I do not have a clue what the next move is to get my bookmarks back.

Can you please help me to get my bookmarks back. Thank you MM

A recent set of system updates appears to have made most website videos not play in Firefox.

When I inspect the Developer Tools - > Console tab the most detail Firefox gives are an error line similar to: Media resource URL could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)

Internet searches for the error name and error hex do not appear yield any applicable troubleshooting, nor any methods of collecting additional problem data.

How can I obtain more detail on where the error is happening and how Firefox might be interacting with other packages present on my system?

Arch Linux has some older ffmpeg-compat packages, but those don't appear to match any of the web results, in that they're even older versions of ffmpeg.

yay -Ss ffmpeg-compat aur/ffmpeg-compat-55 2.3.6-4 (+24 0.00)

When attempting to install a "clean" verison (delete old, install new) I get an error message about using the firefox removal tool. Where do I get it and how do I remove the old one and install a newest version?

My Firefox tab keeps crashing on a particular website. Whenever I go to twitch.tv, the site begins to load and then I get the "Gah. Your tab just crashed." screen. I'm only getting this crash on twitch.tv pages, and this issue just started on May 31, 2024. When I try to open a twitch.tv page in Private Mode, the page loads just fine. I've never had a Firefox tab crash prior to this.

I've tried turning off all of my Firefox extensions, but that didn't solve the issue. I also tried opening Firefox in Troubleshooting Mode, but I still got the tab crash. I'm using the latest version of Firefox as of today's date.

I am trying to open a website but I keep getting error code 522. I've tried using Chrome and it connects to the website with no problem. I've checked my privacy settings and I do not have that website blocked. What else can I check? I don't think it's an issue from the website side.

Installed Firefox 122 in a new Windows 10 installation and added some extensions (e.g. Gesturefly, Update Scanner, uBlock Origin, Uppity). These pinned fine on my old installation. But I cannot find how to pin them on the new.

All the help I have found Googling, or using search here, says go to the Add-ons Manager page and right-click the extension and use "pin to toolbar". Alternatively click the extension and click the gear icon and use "pin to toolbar". But when I right-click there is no pin to toolbar context menu entry. If I left-click the gear I get "Check for Updates, View Recent Updates, Install Add-on From File, Debug Add-ons, Update Add-ons Automatically, Reset All Add-ons to Update Automatically, Manage Extension Shortcuts". If I right-click the gear I get a line of icons (left, right, reload, star) followed by "Open Image in New Tab, Copy Image Link, Email Image, Save Page As, Select All, View Pate Source, Inspect Accessibility Properties, Inspect (Q)". If I right-click the extension in the Add-ons Manager page itself, I get a very similar list. In no case is there a pin to toolbar option.

How do I pin an extension, given the above? What have I messed up?

Hello, maybe someone else seen the same issue.

Why Firefox could respond with VP8 to the H264 request?

I wanted to move the Firefox's automatically created bookmark folder "Other Bookmarks" into another folder (called To Sort folder). The folder was moved to the new location but it also remained in the "root" bookmarks folder. I tried to get it to be the other way round so that the "to-Sort" folder will be in the Bookmarks folder but- Trying to move it back it created a loop. Now when I go into the Other Bookmarks folder I can see the "To Sort" and it has a folder in it called "Other Bookmarks", which has the repeated same links and again the "To Sort" which has the "Other Bookmarks" which has the "To Sort" --> etc. ad infinitum

When I try to open my Gmail account Firefox blocks my messages Firefox blocks my messages

I would like to force spellcheck for all websites, and override any HTML code from the websites. which may be disabling it. This should be done automatically and not by inspecting and manually altering the HTML. I consulted with ChatGPT and tried adding some code to my existing userChrome.css but it is having no effect, even after clearing cache and restarting Firefox. For instance, faxzero.com has a form with spellcheck disabled. I tinkered with the CSS and kept testing faxzero, but the spellcheck always remains disabled. How can I accomplish my goal?

Code: body[spellcheck="false"], input[type="text"][spellcheck="false"], input[type="email"][spellcheck="false"], input[type="password"][spellcheck="false"], input[type="search"][spellcheck="false"], input[type="url"][spellcheck="false"], textarea[spellcheck="false"], [contenteditable="true"][spellcheck="false"] {

   spellcheck: true !important;

}

control + UP (arrow) is documented to "go to top of page". That has broken as of 126.0 And, for some reason I don't remember, I found that using "HOME" in the past was also problematic.

How do I report something as "b roken" to firefox and do you agree it is broken?

I had to restore Windows to its initial settings. I lost all my programs because of this, including Firefox. I reinstalled the browser, logged in to my account (which is synchronized), but instead of recovering all my bookmarks I got nothing. Empty bookmark box. What's worse, they were initially available on the mobile device, but they were also deleted there (both from the browser and from the smartphone). Firefox restored history, add-ons, but not bookmarks. Is there any way to recover these bookmarks?

I have just upgraded the OS on Mac Mini with the M1 chip to Sonoma (14.5) I am running Firefox 126.0.

Now it seems that I have more than one problem since the upgrade. The browsing history in my sidebar is not current. It is running about a day behind.

I reported earlier that the type on my LinkedIn is only out 7 pt when my settings have the minimum size at 14 pt.

Somebody please help. I'm afraid to do a refresh because I don't know what it will do to my banking settings.

Recently, I switched to Fedora 39. At first, Firefox was working fine, but after I logged into my Firefox account, the fonts of some languages stopped rendering, and this started happening with almost every site that was using system fonts.

I am unable to sign into the 7plus.com.au website.

I have tried creating a new profile in Firefox (firefox.exe -p) but I have the same issues when using the new profile.

When I go to the website, the 'sign in' button does not respond, nor does the 'Register' button. When I click on the 'Connect your TV' button and enter my credentials, I receive an error message:

Failed to sign in. Please try again later (error -1)

I do not have these issues if I use another browser, so this leads me to believe that Firefox may be the issue.

I realize the website developers may also be at fault here, but it seems odd that other browsers work, but Firefox does not.

If anyone can offer any help or advice, I am all ears, thanks.

After up grading to a Mac Studio running Os 14.5, I downloaded the latest Firefox 126.0. I have three other computers with Firefox. The oldest a Mac Pro running 10.13.6 Hi Sierra that works flawlessly. I tried sync and bookmarks came over to the Mac Studio but not any passwords. I tried importing via a .csv file and got the message: Import complete New passwords added: 0 Existing entries updated: 0 Duplicate entries found: 0 Errors 190 (not imported)

Firefox will NOT even save manually entered passwords. I suspect some problem with Sonoma's paranoid security but I cannot find a solution. Any suggestions?

I have been using firefox for years. My current version is 126.0.1 (64 bit). Within the last couple of months(?) I am unable to reach a website that I use on a semi-regular basis axisgis.com/AshbyMA The problem exists on 3 different devices, an HP laptop running win 10, an older desktop running win 10, and an older mac desktop running Catalina 10.15.7 which apple says is up to date. If I use Safari on the mac the website works perfectly. If I use private browsing on the laptop the website works perfectly. If I use private browsing on the desktop the website works perfectly. On the laptop I ran the firefox in troubleshoot mode and the website still would not work. I cleared the cache on the laptop and the website still won't work. Since the problem occurs on 3 different devices that are not synced to each other I can't believe it is a cookie problem. Rebooting devices makes no difference. I rebooted the Comcast modem and the house router, no change.

Any ideas would be welcome.

Thanks, mike

Since the latest update, when I right-click on a bookmark or an item in the history list (from the menu or the bookmarks toolbar), I still get the menu that has items like "Open in new tab" or "Edit Bookmark".

However, the focus for the mouse stays on the previous menu, so that I can't click on anything in the "right-click menu", instead it is interpreted as a click in some random item in the previous menu.

Going into troubleshoot mode didn't help, so I don't think it's my configuration causing this.
