Firefox 技術支援討論區

While there are some things I like about FireFox, I use another browser for the vast majority of my browser use... I'm running Linux, and it seems that FireFox has locked itself in as the default browser... Since I am unable to modify that condition, is my only recourse to uninstall FireFox? Or, am I missing some secret handshake?

All my other applications and browser apps show a "toolbar", the uppermost edge of my screen, with "Firefox" and bookmarks, etc. It is just gone. I can't figure out why it is not showing up or available. I am not in full screen mode, although that hides the bar on top also. Mac OS 10.11.6, preferences says latest available update, although I cant tell because I can't set the "About" Firefox button.

Greetings,

I just updated to Firefox 78.15.Oesr and now am unable to reorder my open windows. As a student, I may have several projects open at a given time, and like to have the project I am currently working on, next to the open Firefox window, for quick navigation between the browser and project. This option seems to have been disabled with the update. It is enough of a deal breaker that I may pursue reverting to the previous version of Firefox.

Also, the inability to delete bookmarks, and to close the bookmark window after selecting "show all bookmarks," remains a persistent frustration that I am surprised has not been addressed. With so many browser options available, these subtle annoyances are enough to prompt me to again shop around for alternatives, after being a Firefox devotee for over 10 years.

Thank you for your help, Josh Baker

On another user's account, cannot go back to earlier FF version, profile files missing. Cannot start _any_ revision, old or current (using OSX Sierra on that user & different FF versions - the shared data you see her is NOT the same ) details here: https://support.mozilla.org/en-US/questions/1356226

I don't see the profiles.ini and installs.ini files within the Profiles folder. I see the general format from looking at good ones in my own Profile.

Don't understand why some are "locked."

How do I re-create them using the existing Profile names, and how do I denote which to startup using (the default folder?) Can't find any Help files to explain.

This is driving me mad, we are using the same physical computer because mine broke, so I start it up off an external drive containing my drive, then I have to shut down & restart on the internal drive to work on it, but then I don't have access to my saved files or to post on the forum.

Hi,

I found some discussion related (https://discourse.mozilla.org/t/disable-add-ons-on-specific-website/33693) but no solution yet.

This is imho a big flaw in the privacy of users.

There are trivial cases, for example if I use a YouTube downloader plugin, I obviously want it to monitor my browsing ONLY when I'm on youtube.com...

And there are some critical cases: when I browse my web banking, or when I go on some trading website, I don't want my financial operations to be at risk because of an add-on that is very useful everywhere but on those site.

However, I don't want to exclude all the add-ons for those website too, that would be just too much.

I think there's already a coding base in place, since you can disable each add-on when using private windows. This could be enhanced by having a system of whitelist/blacklist instead. And this feature would actually make more sense than using a private window.

Another way would be to have this feature on per container, instead of per website, than would work well too.

People have different activities, and some requires useful plugins, that are very specific. I mean Keepass's add-on (for example) is useful everywhere, but many add-ons are related to one activity at a time.

For example, if I'm a marketer and want to analyze website, I'll use add-ons for having stats on metadata or keywords or even real time reports from Alexa or from AliExpress, etc...

But when I'm reading my email, I'm not happy those add-ons can see my data.

That would be tedious to disable all those plugins every time I change activity, especially since we are productive humans so obviously we need to alternate those activities doing multitask all the time.

And the private window option is not flexible enough for that kind of multitasking, when containers are.

I hope this helps everyone understand clearly why I think my request is not only a real user need, but also currently a flaw in users privacy since most people will not trade the comfort of their add-ons for some privacy concern they don't always understand...

I know this is some kind of feature request more than ask for help, but https://qsurvey.mozilla.com/s3/FirefoxInput/ is out of service so I don't know where to address my concern here.

Thanks for helping me pushing this idea forward.

I switched my internet from one Mac to a newer one but I have hundreds of bookmarks that I need to copy over. I found and copied the profile document that holds all of the old bookmarks but I don't know where to put it in the new High Sierra OS folders. They are not the same as the old Mac OS has. The old OS has folders in, User, (my name), Library, App Support, Firefox, and Profiles where the bookmarks are stored. - - - Anyone know what folders these have to go into in High Sierra? - Will be most appreciated!

I've written about this before, but no help? I'm using Firefox Mac 78.15 (up to date). When I go to CNN and select a video, a thumbnail (still image) of the video appears, but no player with controls, so no video. When I do the same on Chrome, I get a video in a video player, which plays just fine. Also, all other videos on FIrefox (YouTube Fox News, etc.) play just fine?

Since upgrading my iMac to Big Sur, I get an extra Firefox icon in my dock. Now, here's the strange part: it has a small screen on the icon at about 2:00. Even stranger: it connects to the website my wife has on her macbook. It gets stranger: the Firefox icon with the screen appears even if my Firefox app is off. And finally: the icon connects to her Safari app, not her firefox app. That is, when I click on the icon with the screen it shows me her Safari website.

I am at a loss.

The refresh button (circular arrow has gone from the toolbar It is not present in the customise list It is restored if I I select 'restore defaults' but is only there for the current session and not when firefox restarts So how can I add the restore button PERMANENTLY please

Tenho uma rede com mais de 500 computadores, publico documentos em pdf com bloqueamento de impressão na intranet, o firefox tem o plugin de pdf nativo e esse plugin quebra a segurança configurada do pdf, que no caso foi bloqueada a impressão e no firefox qualquer usuário consegue imprimir. Gostaria de saber como faço para desabilitar o plugin nativo pdf do firefox para todos os usuarios e que não consigam mais ter acesso em mudar a configuração, igual como fazemos com as configurações de proxy, onde fica desabilidado para o usuário a alteração

I used to have a speaker icon on my tabs but it has disappeared. Any idea how to get it back?

Also I lost the "reopen closed tab" function as well.

Please help with either or both of these issues.

TIA

Hi,

My configuration is Firefox 78.14.0esr (64-bit), running on Slax, a Linux live distro based on Debian 10.

The URL I'm having trouble with is https://oldtime.radio. I click on a channel on the main page and the audio appears to stream. The tab in Firefox shows the speaker icon in the corner, but I get no sound. I've tried launching Firefox from the command line in safe mode with a new (blank) profile with the same behavior. No error messages in Firefox or the console. YouTube plays okay, as do various news sites. When an audio file is "playing" on the old time radio site, a link appears to download the corresponding mp3 file. If I click that link, the mp3 file autoplays correctly. Just streaming doesn't seem to play. I tried the site in Chromium and it works correctly.

I'm not sure how to further troubleshoot. I suspect there might be something like a codec that Firefox isn't finding that is included with Chromium but I don't know how to identify or trace what the stream is from the site.

Thanks,

Pat

I am using firefox in linux mint basically and today I noticed that when I click on a youtube link it opens my firefox and then the youtube website and the video loads but the video doesn't play and keeps buffering when I click on the play video button. And then if I click on other youtube video those doesn't work too. So I have to close firefox everytime and then when I manually visit the youtube website everything works. But if my browser is closed and then I click on the youtube video it loads the video but doesnt play it and keeps buffering.

Hi,

We are using firefox as the browser client for a webrtc based video streaming application. The other client is Gstreamer webrtcbin. The communication works fine with FIPS mode disabled, but it fails when we enable FIPS as part of security. The Gstreamer client sends an SDP offer to the firefox browser client, but it fails to create an answer and respond back. The WebAPI (RTCPeerConnection.createOffer) fails with below exception at application code.

"UnknownError: The operation failed for an unknown transient reason"

Also, tried to check some failure message in browser log and found as below. Not sure if it is related to the failure.

NS_ERROR_ILLEGAL_VALUE: Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsICryptoHash.init]

System setup:

OS - OpenSUSE 15 SP3 Firefox version - 78.13.0esr (we also tried with version 91.10.0esr)

Any quick help will be much appreciated as we are stuck with this.

Thanks, Saurav
