Firefox 技術支援討論區

Firefox was working fine yesterday. But all of a sudden while playing a youtube video it started being choppy. It drops frames, scrolling and video playback are choppy and laggy, there is lag on button inputs, the system is choppy and laggy too while firefox is open, especially when video is playing. I checked the CPU and GPU usage and I can't see any spikes. I have tried refreshing firefox but that did not fix the problem.

OS is manjaro linux (gnome version) latest. Firefox is also at the latest version.

Hello,

I get Secure Connection Failed - SSL_ERROR_HANDSHAKE_UNEXPECTED_ALERT error code randomly while trying to open youtube.com. It works with other browser. Please help to solve this problem.

I've checked a couple of the "similar topics" before posting here. I'm not sure if I am having the same problem or something else.

Back Story: I have a "few" windows and tabs open in FireFox. I would finish what I was doing, shut down and then the next time I booted up and loaded FireFox, all sessions would be restored and all log ins honoured (kept). That is: I was still logged in.

(Moving to now) Yesterday I powered up and ALL sites were logged out. About 20 log ins were needed. Hmmmmm... gmail, and the rest.

"Ok... something happened. No problems, things should be ok from now. I've logged in, so all is sweet."

Today I power up: All logs ins lost. Had to go through it all again.

Gmail is throwing security alerts at me hand over fist. Yeah, that is good in some ways. I get that part. But I've logged in.

Seems - my thoughts - that the cookies aren't being saved. But why? I haven't touched them or their settings.

Yes, I did do a clean out of older cookies. But left the gmail ones, and other sites I know I use. I have `adblocker ultimate` installed.

Now I am logged in, if I open the `cookies` and look I should see them there for the sites to which I am logged in - yes?

To be clear: When I am done, I do NOT `exit` FireFox. All windows, tabs, sessions are left. I just shut down the machine. Then next time I load FireFox and they are re-loaded and log ins are maintained.

I have some websites in the internal network with self signed certificate which I have registered in the exceptions. But every time I visit them he asks me to put them back in the exceptions. Is there a way to fix this problem?

I'm using freshly-downloaded Firefox version 102.2 on a brand new laptop (Windows 11 Pro version 21H2), and every single extension is showing a "Installation aborted because the add-on appears to be corrupt" message when I try to install. I have tried checking for updates, quitting and reopening firefox, restarting my computer, refreshing firefox, uninstalling and reinstalling firefox, as well as any and all combinations of those. I've scoured these message boards and nothing is working for me. Please help!

Hi I have a problem with Firefox (102.0) downloading / saving files to Macbook (OsMonterey). The files are saved in strange machines with the ending part. Ex: video.mp4.part The files cannot be opened. Has anyone had a similar problem and can I ask for support?

Until the most recent update of Firefox, I was able to access atrribute data of a GIS map feature on the GIS Open Data, State of Michigan website:

https://gis-michigan.opendata.arcgis.com/datasets/2020-voting-precincts/explore?location=44.909859%2C-86.310800%2C6.97

Now, I can not click on any feature. I can do this, however, using Chrome. What is the issue, here?

- Marquis has colonised my search page. - I used to be able to get rid of it temporarily by going into troubleshoot mode and going through that whole process twice - oddly, it never worked first time. - Now that doesn't work. - I can only get to my DuckDuckGo homepage via my bookmarks, which means I can't have more than one page open at a time. Firefox opens by default in Marquis. - I downloaded paid-for antivirus software with no results, so I'm reluctant to get anything else unless I'm sure it will work. - I notice that several people on this thread and elsewhere have reported this intrusion. - Does anyone know what to do about it??

How do I restore the display of this vital information? Why was it removed in the first place???

Edit: This is at least the case for downloads where the conclusion results in the file being opened, instead of saved: https://cdn.discordapp.com/attachments/628080126630035466/993530387601043557/unknown.png

The present configuration of Bookmarks:

Both "areas" of Bookmarks are linked, deleting from one will update the other. Neither are isolated personal storage areas for selected bookmarks of the user's choosing. You can't keep/delete one bookmark in one area (Bookmarks toolbar and/or hamburger icon > Bookmarks) without the action being correspondingly reflected in the other area.

Now previously I could go to the hamburger Bookmarks, create and delete without my tool bar Bookmarks being effected. Any chance of this happening again please?

In the last couple of days I cannot log into Twitter in Firefox. I get a message that something is wrong "but don't fret, it is not your fault". When I hit Refresh, it works, but only once. What is wrong? I have the latest Firefox version. Thanks

Whenever I try to open google or search anything, It shows this error and only button to Go Back

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection. What can you do about it?

www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

Someone could be trying to impersonate the site and you should not continue.

Websites prove their identity via certificates. Firefox does not trust www.google.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

Hello, I have a problem with firefox and it's recently unable to open Google and Youtube due to HTTP Strict Transport Security (HSTS) with an error Code : SEC_ERROR_UNKNOWN_ISSUER

I have done the steps in here : https://support.mozilla.org/en-US/kb/error-codes-secure-websites I don't have any third-party Antivirus

I have also do about:config security.enterprise_roots.enabled by changing to true. It works but unfortunately youtube is broken when i set it to true.

I can't also accept the risk and continue since there's no button that says it.

Thank you

On a website I regularly visit Firefox does not know what to do with an mp3 link and will not prompt for an action.

How can I add MP3 to application list?

Copy of application list attached.

Please see the message below recieved on a web site I use daily when i wanted to review some information about my accounts -

406 - Client browser does not accept the MIME type of the requested page. The page you are looking for cannot be opened by your browser because it has a file name extension that your browser does not accept.

Immediately following a Firefox update I began having scrolling problems on my Facebook page. I am able to scroll down normally to a point, and then, all of a sudden, the scroll bar will go up and immediately go back down without me touching the mouse. It will continue doing the up and down scrolling indefinitely and at a high rate of speed. I have tried turning off auto scroll and smooth scrolling at the browser, but no luck. I have Windows 8.1. I have never heard of anyone else having this problem so this seemed like my only option.

Hey, some websites break and show weird fonts when the option to let them use their own font is disabled from the prefernces settings. Is there anyway to allow an individual website to use their font if they want to?

Couldn't open Firefox XPCOM error.

Downloaded Firefox again and I now have Firefox in OS/Program Files/Mozilla Firefox (which doesn't work - XPCOM error) and a second version in OS/Program Files (x86) which works but has lost all my bookmarks and passwords.

How can I fix this please.

On the console log, it is giving a bad gateaway for the post request when I am trying to add photos from the attach option given below. Same issue on mobile app as well.

I get the "PR_CONNECT_RESET_ERROR" every time I access a google.com related domain. I don't get the error on other browsers, nor do i get the error on other sites within Firefox. I've cleared my cache, cookies, restarted my browser, tried turning off the proxy functionality in network settings, etc. This all started immediately after my browser was upgraded to 102 (current version is 102.0 (64-bit)). Please help. This is so frustrating that I'm ready to simply delete Firefox and revert to Chrome, which is a bummer, but this is kind of a dealbreaker bug and i've already spent an hour on the forums (using Chrome, because I can't access Google search) trying to fix this.
