Firefox 技術支援討論區

It has recently come to my attention that Mozilla may not continue to support Firefox browsers installed on Windows 7 computers after Jan. 2023, when the extended support for Windows 7 ends. Is that correct?

Will Firefox continue to work, but not receive security updates after that date?

Will Firefox still work on a Windows 7 computer that gets patches from 0Patch?

Thanks!

Hi, my Firefox keeps crashing on using youtube (on openening youtube.com or any site which integrates a youtube video). My crash report ID is as follows: bp-d25e9417-a29a-4ce2-ac69-1e8460220329 Is there anything I can do? Thx a lot, Maike Scotland

When I am watching a TV stream on my PC; when I hover on (some) pictures or videos, a supremely annoying pop-up url appears at the bottom of my screen. I have some learning problems and can not figure out the 'userChrome.css' method. I can not work with long streams of multiple overlapping instruction. I am not tech savvy. I do not understand 'layers' and stuff like that. I can do the 'about:config' thing, if anyone knows whether or not if I can fix it from there, I would be eternally grateful. Thanks.

Many file types are no longer listed under Settings > Applications>Content Type at about:preferences#general. I used to be able to click on a file in an email like a Word or Excel document, and it would come up on my screen. Now Firefox asks me to Save them. I don't want to automatically save files without first looking at them. How can I get those file types in the Application list again?

I have attached a pic of the file types I have left to chose from. There used to be a lot more. How can I get back all the missing choices I have had there for years?

I always relied on the "+" at the right end of tabs to get a New Tab, but it's disappeared, won't come back on reboot, doesn't seem available as a customization. It's not the greatest problem in the world but it is annoying when handy shortcuts disappear!

Ive never noticed this until last night but how come when i use a theme it controls whether website pages i browse will be light theme or dark theme? is there a way to turn this off? I have a theme on rn and i like it but i cant use firefox atm because certain websites i browse show up as dark theme and i hate that i just want them all to be light theme. Thanks for the help in advance.

I recently upgraded my system and, after installing and using Firefox, I notice the Find (Ctrl + F) bar is now at the bottom of the window. Whereas, it was previously at the top (which is more like every other application I use).

After some head scratching and web searches, I remembered I had to fix this issue previously (after a Firefox upgrade some time back). The method to fix it then could be found here: [there a way to put the Find Bar at top] That link is of course to the same question asked 4 years back.

I have once again followed the procedure there explained per: • Access my Firefox profile folder. In my case:

  C:\Users\<Me>\AppData\Roaming\Mozilla\Firefox\Profiles\5ym42ewi.default

• Create folder therein called ‘chrome’ • In that folder create a file called ‘userChrome.css’ • In that file add text:

  .browserContainer > findbar {
    -moz-box-ordinal-group: 0;
  }

However, after doing that (and restarting Firefox), the Find bar stubbornly remains glued to the bottom of the window.

Can anyone tell me how to solve this issue?

As a separate note to the developers: This issue is long-standing, that a web search reveals is still relevant to many users. Any chance of considering making it a standard option?

I've used gmail (with multiple email accounts) on Firefox for many, many years. I switch back and forth between my email accounts daily.

In the past few weeks, though, when I try to switch from my primary account to the others, it just defaults back to the primary. I've purged the cache, I've signed out and signed in. This does not happen on Chrome, just Firefox, which is why I've brought it here.

If I change the URL of the mailbox

https://mail.google.com/mail/u/0/#inbox

to

https://mail.google.com/mail/u/1/#inbox

It will take me to another mailbox. I can then change that number to get to the others. But it shouldn't be that way. So ... what is going on? How do I fix it?

Hello. I noticed that Firefox (98.0.2) doesn't even ask if the file should be saved or opened with a program when downloading some file types. Unfortunately, these file types (e.g. GPX) are not listed under Settings --> General --> Files and Applications, so that I could assign them to a program or specify that they should always be asked. And I can't add these files somehow... I have also deleted the file "handler.json" in the profile folder, hoping to be asked then. But that doesn't happen. GPX files, for example, are assigned to the GSAK program in the system - but Firefox just wants to save them and doesn't offer the option to open them directly in GSAK. Does anyone know advice how I can get Firefox to give me the choice? Thanks a lot.

I contacted the Daily Mail newspaper because I keep getting their popup news alert messages even when I am reading my email. My Firefox popup blocker is checked. I complained to the news paper and they gave the following message to get rid of these annoying messages. Here are their instructions to stop this on Firefox> 1. Click the Settings icon in the top right of your browser window and choose "Preferences" 2.From the left hand side of the page, choose "Content" 3. Under Notifications, press "Choose

There is no Preferences category under my settings icon. There is no Content on the left side of the page when I go to Settings There is no Notifications label from which to select Choose.

How the heck do I get rid of this annoying popup or notification or whatever the heck it is? Please advise. Thx

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.

Unfortunately, I downloaded “SaveFrom.net Helper” without reviewing it.

Since downloading it I have been receiving a alerts from “McAfee WebAdvisor” about “dangerous pages blocked”.

I was able to remove the “SaveFrom.net Helper” add on in Firefox, but am unable to remove the “Savefrom.net Helper” bookmark tab which has high jacked my normal Firefox Bookmarks.

I can no longer easily see my Firefox Bookmarks and have to keep opening the Firefox Application Menu, then select Bookmarks, then select Manage Bookmarks in order to see my bookmarks.

Can you please advise how I can safely remove the “SaveFrom.net Helper” bookmark tab which has high jacked my Firefox Bookmarks.

I've posted this problem before and did receive replies attempting to help. Unfortunately, the problem has continued for a long time (I think at least a year). I frequently can't access websites (e.g. Yahoo Mail) using Firefox but can using Edge or Brave. With Firefox, I get the following error message:

"Secure Connection Failed An error occurred during a connection to login.yahoo.com. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

I had hoped that the problem would be solved by a Firefox update but that has not happened.

I also regularly get the message "No Internet Connection" while using Firefox but, when I use Edge or Brave while the error message is displayed, there is Internet connection.

I'm using the latest versions of Firefox and Windows 10 Pro.

I've used Firefox for many years and really don't want to have to switch to, say, Brave.

I have the Startup checked, to Open previous windows and tabs, but when I close Firefox, all tabs are closed. I have "Remember history" selected under History. Under "Cookies and Site Data" the box that says, "Delete cookies and site data when Firefox is closed" is unchecked. See uploaded images.

I want to be able to print my .docx files without saving them first. I went to General and Applications. .docx is not in the list, so I'm unable to select how it handles these files. How do I add .docx to the list of content types?

I use Firefox to read books in pdf format. I want to record the location everytime I close the pdf file so that I can easily go back to where I leave last time. But I notice no matter where I am in the file, the url does't change. I think it's the reason why everytime I click the bookmarked file and the Firefox just open the file on the first page, not the location I leave last time. Is there any way to record the location I leave?

Hi, for the long time when I have opened an PDF with external application, it was downloaded into system %TEMP%, then deleted after ext. app was closed. Very fine and expected.

Since ca. few weeks such PDFs are now downloaded to Desktop - and not removed afterwards! It's quite annoying to clear them again and again. I've checked, my %TEMP% and %TMP% are set correctly and writeable.

Having just upgraded my Debian 9 machine to Mint 20, this has updated my firefox browser.

Everything was going fine until I came across the problem where by all image downloads are saved as webp images, a format that my favourite image editing software cannot handle.

This is a bit of a pain and has made me start looking at alternative web browsers.

Just thought you should know how simple things can cause a loss of support.
