Firefox 技術支援討論區

Firefox has begun opening very [very!] slowly, as well as crashing and freezing during use. This is happening on all of my three machines, two running Win 7 and one Win 8. I have tried refreshing and disabling hardware acceleration, but to no avail. Now it seems to freeze on opening and takes a minute or two even to become responsive, if at all. When I look at Task Manager during a freeze I see the Firefox process is using 35-50% of memory [i have 8GB, 12GB and 16GB] and up to 50% of processsor resources. All has been fine until the last couple of weeks. As an adjunct, in the last month I have noticed an almost permanent error message on the status bar - "Sync encountered an error while synchronising: Unknown error. Sync will automatically retry this action."

I freshly installed Windows 10 and I can't install Firefox inside "ProgramFiles (x86)" I tried running as admin, changing admin privileges but nothing worked, then I tried to install it inside "C:\Users\*username*" and that worked. Any ideas why this might happen?

Since some time I get the error code "SEC_ERROR_UNKNOWN_ISSUER" on reliable websites. But it is not possible anymore to add an exception as described in https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER?as=u&utm_source=inproduct. Is the outdated info??? So, the only way to use these websites is to use another browser. What's going on here?

This should be a simple process, as I have done it before on other computers - but the icon is only in my dock as a "?", which I click on , and then it opens up to the Fox/World icon. As soon as I shut down the computer - the Firefox icon disappears.

I've upgraded to Win 8.1, Firefox v26, Shockwave, Flash, and the newest Java JRE's. YouTube videos result in an error message and to try again later. The interesting feature is that IE v11 will show the videos with no error. The Win 8.1 upgrade took away my sound, and I've read the other problems that seem to be related to YouTube and sound. But, IE plays the videos with no sound, so that's not sound related.

I am getting a solid red screen with screeching sound saying a web site is trying to do something to my computer and that it's a FIREFOX CRITICAL ERROR and I need to call help desk. The only way I have found to close the window is to open Task Manager and close Firefox. Sometimes after rebooting the page will go away for a period of time but it always comes back. HELP! How do I get rid of this monster? The Windows 10 Virus scanner won't clear it and neither will Malwarebytes malware scanner.

Thank you, Jake

I am trying to turn off my cache settings.

The instructiuons given tell us to set 'network.http.use-cache in about:config.

I have tried that, and that Preference name no longer exists.

How is this achieved?

I need this for Automation Testing. Currently, cached data casuses tests to fail.

I am trying to display streaming content from 4 webcams within my local network. This works properly on my Linux Mint box with Firefox 48.0, but does not work on My macbook running OSX El Capitan 10.11.5 on Firefox 50.1.0. Also same problem on my IMac.

The html code is like this...

<object type="application/x-vlc-plugin" data="rtsp://LWK-????:????????@192.168.1.xx:554/img/video.sav" width="500" height="375" id="video1"> <param name="movie" value="rtsp://192.168.1.0/archive/xxxxxxxxxxx"/> <embed type="application/x-vlc-plugin" name="video1" autoplay="no" loop="no" width="500" height="375" target="rtsp://LWK-????:????????@192.168.1.???:554/img/video.sav" />

I downloaded Flip4mac, as was advised on a post I found on stackoveflow, but that made no difference.

How do I know which plugin is needed? Searching on extensions, I see nothing for x-vlc-plugin. Is extension same as plugin? What do I download if not Flip4mac?

Any help would be greatly appreciated, Thanks, Joe

Been receiving "Temporary Error 14" for days now??? I followed the "Workaround" by Signing out of Yahoo Mail, clearing cache and cookie, restarting my web browser and signing back into my Yahoo Mail several times with no success??? Other Family Members are able to log into their Yahoo Mail using the same computer with no problem??? I'm using Firefox 28.0! I'm able to sign-in on a friends computer with chrome???

When I first got on the Firefox browser a full page red screen came up with white letters, telling me I should call a certain number (I didn't write it down - didn't call either). On the main red page it said my passwords may be compromised and I should alert my bank accounts, etc., Other smaller alert boxes came up, but I don't remember what was in them. I eventually cancelled all those alert boxes and logged of. The next time I got on Firefox was fine. Does Firefox give out numbers to call in a case like this? Is my computer infected? Thank you/

Programming in PHP. kind of a form (actually it is not a form but it uses form elements - js is used to submit.) When submitting, data is stored in session variable, and the page is reloaded, same form is shown, with data modified (formattet different). This shows data the way the user typed them - not the way PHP formats them.

Useless.

And yes, I have verified, with a different display section, that PHP is actually doing what it's supposed to - but firefox does not display data in input lines, the way they are programmed - they do not display the programmed value, but the value the user typed last time.

Likewise the web tool, does not show the actual sourcecode, but a modified version of it. Selecting "View Source" does not give the same source as "Inspect element"....

FF 49.0.1

Whenever I use a website which uses my location it puts me somewhere in the UK m idlands, far away from my actual location on the south coast. How do I correct this please?

Firefox crashes constantly. Tried starting it in safe mode, and then disabling the javascript-line. Helped for a few days, but now the crashes are back

The 10 latest crash reports (all today): bp-9ce11f44-53e5-4e5b-8d24-444a82140530 bp-4f853bef-a467-421f-b200-5aa2e2140530 bp-24843b24-7d08-4ab1-8c13-204082140530 bp-e8274262-219f-4711-8e85-560622140530 bp-2ba874e6-ca77-490e-aa31-39e152140530 bp-21dc620e-59aa-4084-a823-80a9a2140530 bp-a9aebf9c-acf2-47ec-b0d5-449102140530 bp-603cd787-208a-4c23-95b0-db5822140530 bp-ac705fb4-f382-4957-bbe0-141b52140530 bp-677b2c3c-2160-4959-a005-62f6a2140530 bp-a8f5a9c1-6ddc-40d0-b21d-812c42140530

There is right now literally no obvious way to bookmark a page. This is a serious flaw in the browser.

The Forum instructions say to restore it from "Customize." But it's not there, just the bookmark menu button, which does not allow you to bookmark a page. It then says restore defaults. That doesn't restore the star either. Does anyone know how to get it back once it's gone? It should not be so difficult that I can't figure it out.

Was there a recent change that invalidates private certificates, with it's private CA imported into my FF CA repository?

What I have set up, which worked not too long ago, which was defining the IP address and host name in C:\Windows\System32\drivers\etc\hosts file. Then importing the remote site's private CA certificate in FF. From that point on, it trusted my private URLs due to matching private CA. Now, generates SEC_ERROR_BAD_SIGNATURE.

I renamed the cert8.db file and restarted FF. I now get the normal "untrusted" error then re-imported the private CA to make the "untrusted" error go away. However, that still gave me SEC_ERROR_BAD_SIGNATURE. So, something must've changed.

I even tried disabling OCSP checking (thought it was optional if it couldn't check). I then disabled OCSP Stapling. Neither resolved this issue, thinking it was trying to check with the OCSP server, which it can't reach due to firewall since it's internal to the other private LAN.

I'm not sure where to look. I tried Googling for answers, which lead me to the above two solutions to try.

The CA I have is a private CA, generated by Microsoft Windows Server 2008 R2 with the Active Directory Certificate Authority installation. Like I said, it was working in FF fairly recently. Let me know what else you need for me to provide.

Hello,

I'm web developer and working on a local website. The problem is when I made changes in my css file it won't reflect in firefox when I refresh the page. HTML changes are getting reflected correctly. Only the problem with css files.

I have to refresh the page like 20-30 time and after that css changes are getting reflected.

In all other browser website working fine and also changes are reflected as it should, only firefox creating problems since last some days.

I have tried the following solutions and they are not works if it helps. 1) Try Shift + refresh but not working 2) delete cookies.sqlite but not working 3) Download and install newly download firefox but still no luck. 5) DOM storage is also enabled 4) Also formatted the PC (for other reason :)) and installed Firefox on fresh system but after that also no luck

I'm using latest firefox. Please help me with some solution it's is very problematic in web development, right now I've to use another browser for time being which I don't like, because I love Firefox.

Please reply as soon as possible.

I can't open a new window. I can't select preferences. I can't shut it down even when I try to force quit. Going to the finder and shutting down does not work. This prevents me from shutting down my computer.

Hi,

I have a spr532 card reader with a test smartcard with Firefox 50.1.0 on Ubuntu 16.04 up to date. I want to use the client certificate from the device to log in on a website that I am developing.

I also have a test certificate that I generated and it is not on the card. I can log in with the test certificate that I have but not with the one on the card. The problem is that in the "User identification request" page I cannot see the certificate from the smartcard. I can see my generated certificate but not the one on the smartcard. Firefox asks me for the pins for the smartcard (I have two certs on the card and they both have PINs). Firefox sees my certs from the smartcard in about:preferences#advanced > View Certificates > Your Certificates column. I have both the certs on the smartcard and the one I generated in that table. But when I try to log in, Firefox only shows me my generated cert and not the one from the smartcard.

What can I do? How can I debug this? This is a dev environment. I can change any configs on the server so I can decrypt the TLS session and see what is going on between my server and the browser.

PS: I tried to send this message with 2 other email accounts but I do not get the confirmation email.

Thank you!
