Firefox 技術支援討論區

For the last several months pages on my websites don't always show correctly after i've updated them. I then need to go into the settings/privacy and delete all data to see the correct changes.

When starting Firefox I used to to see my "BBC NEWS" home page at that time. Now when Firefox starts I get "Sorry can't find that page". If I select "restore previous session" I get the news page from the last session not the current news ! Is there a cure for this ?

One of my tabs split off from the bar leaving me two versions of Firefox open. I accidentally closed the main page with all the many tabs first and thus the single tab page was closed last which means the command to restore or open all the tabs doesn't work. You have the choice on the Firefox set up to Open the pages that were open when you closed. Unfortunately is there are what appear to be 2 Firefox browsers open if the unwanted one is closed last -- all the tabs from the other one do not restore and I can't find them in any kind of history.

Is there anyway to find/restore these tabs? Many were open and some of those to remind me of things I can't now remember were there, so I cannot find the information.

Thank you for ANY help with this.

I am using Firefox 96.0.3 on a MacBook Pro. Since around Jan 25, the bbc.co.uk/news website does not display correctly. See image below. The main BBC page is ok but all sub pages are affected. I have cleared cache and looked for obvious blockers etc. but I can't see what's wrong. Please help!

When visiting sites such as the Russian Wikipedia, characters that are in the Cyrillic Times New Roman font display as blocks (shown in image). Safari does not have this problem.

I cannot use Firefox to browse any more, because it refuses to load gmail and/or youtube. These are sites I have used thousands of times in the past, but recently Firefox will not let me go there any more, and it says "secure connection failed." It also says I should "contact the website owners" to inform them of this problem. (Good luck contacting Google!) Seems like this must be an error, since I have used those sites many times in the past. I have looked at this page of Mozilla's: https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect But it is too long and technical for me to deal with. Anybody have any suggestions about how to get Firefox to not freak out when connecting to a Google service?

I just noticed that on the Logins & Passwords page (about:logins), it is possible to search on logins by password. In my opinion this is a security threat, as it makes password guessing nearly trivial. Sure, an attacker would have to get their hands on your laptop/computer, but they can use this strategy to find your password without having to know your master password. I'd love to know whether A) this is intended behavior, and B) if so, if there is a way to turn this off.

Following a VERY troubled update to Windows, which required several hard shutdown/reboots, invoked an automatic attempt to repair Windows, reported that the repair attempt failed, but then booted into Windows normally, the only thing that seems to be wrong is that certain websites report "Secure Connection Failed" with an error code PR_END_OF_FILE_ERROR. Contrary to the support page, there is no option to report this to Mozilla; the only option is to retry. When I click retry, I get the same page with the error code PR_CONNECT_RESET_ERROR. This is not a problem with the website -- same website works fine in Firefox on both other computers in house, one running Windows 10 and one running Windows 11. This is not a problem with the operating system -- I have used both the system file check and distribution manager to check/repair Windows system files, and also successfully accessed the web page using Internet Explorer (Microsoft Edge is disabled in Policy Management). So this is clearly a problem with Firefox. I attempted to reset Firefox, but it didn't help. I then uninstalled Firefox, and attempted a clean re-install; I'm not sure how clean the reinstall was, because it detected the prior installation, and imported things. The sites I can't access include Wikipedia (of all things!), some links in the Firefox support pages, and my on-line banking website, which is pretty critical. Other websites work just fine, including most of my other financial accounts -- credit cards, etc. HELP!

I'm running Firefox 96.0.3 on Linux Mint 20.3 Cinnamon, and have a Brother MFC-5890CN printer. Whenever I try to print from within Firefox, the default paper size is incorrect (it varies, occasionally being close to US Letter size but often being extremely small) and every option is shown in mm. I have to click "print using system dialog" to select US Letter (which is set as the printer's default). I have reset the printer settings, but this has no effect. I have not encountered this problem with any other application. How can I set the size list and default size properly?

Recently when using Firefox, I have encountered several site (vanguard.com, publix.com...others) where the site will not process my login, but if I open the site in a Private window, it works normally. What might be causing this? Du Other info: Windows 11, Firefox 96.0.3, no VPN, AdBlock add-in, LastPass add-in, Duckduckgo. Security settings at Standard.

Thanks.

Problem has been reported before and archived (https://support.mozilla.org/en-US/questions/1343948) The solution worked, but if lots of people are seeeing this, it should be fixed permanently rather than use a temporary fix.

Hello, For quite some time, Firefox seems to have a problem with Google docs. 1) The text on Google docs is blurred. I have attached screenshots that compare its appearance on Firefox and Edge. 2) Some functions of Google docs do not work. I can't use the shortcut Ctrl+Alt+M to insert a comment, but on Edge, this works fine.

I am using Windows 10, Firefox 96.0.3. I have tried restarting Firefox in Troubleshooting mode, but it made no changes to these issues.

What could be the reason for this?

Please let me know how I can get my old bookmarks as I do not have any on file in the restore area the only ones I have are five teen year old ones, Can you please help me restore them to the my original ones?

Hi! I wanted to reach out to Firefox support about an odd issue that's been happening for the past month or so.

When I go to interact with an idle open window or bring a minimized window to the foreground, I'll randomly get no response and hear an error noise. Firefox never has any associated error messages, and it has yet to show "unresponsive" status when this happens in Windows 10. I'm wondering if anyone else is running into this issue, as it started roughly the same time with both my work and home PCs. Perhaps a recent Windows 10 and/or Firefox update is the cause...?

Hi.I would like to know how i can stop this site from constantley trying to connect with my P.C.luckeley my firewall stops it but eventully they will succeed.Iplayed it a long time ago.I stopt,deleted my account but they keep attacing several times a day.I,ll be gratefull with any help\advise about this.i tryed acsessing the page sourse and i think i,ve only made it worse.

I am unable to access my banking web site using Firefox (Navy Federal Credit Union) as well as some other web sites such as REI. I have the latest Firefox edition. I am able to access these websites with Chrome and Edge. Why can't I use Firefox?

As the subject says, when playing some (but not all) videos ending with .mp4, Firefox will show a page with a box containing the error "No video with supported format and mime type found." Sometimes the video's sound will play but the video itself will be a blank black box.

I have already tried the following:

• Clearing all cookies, cache, and data
• Disabling all addons
• Using a brand new vanilla profile

I have tried the videos in Google Chrome and they work just fine. I also experimented with video players. Windows Media Player is incapable of playing them yet VLC player, DivX player, and Media Player Classic all play them just fine. Could this just be an issue with the version of windows on this PC?

I am currently running Windows 7 Ultimate 64bit.
