منتدى دعم ”Firefox“

I am using Linux platform. Web browser is Firefox. Whenever I open my face book the USERNAME and PASSWORD is visible in the respective column. How could I clear this. I have tried several times by clearing cache and cookies but there is no use of it. Kindly help me.

Found existing message that Firefox 53.2.0 is available for XP, but the download link on the page only offers v. 57. I'm trying to download on a Linux machine that is running v.40 which I will update, but still need the version for XP. The XP machine is airgapped so can't download directly.

Nothing happens double clicking， running ./firefox gives

XPCOMGlueLoad error for file /home/yang/bin/firefox/libxul.so: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory Couldn't load XPCOM.

Firefox downloaded from mozilla.org firefox-23.0.tar.bz2, system Fedora 19 64-bit

I cannot access a clients site that I'm working on due to an HSTS error, I used to be able to bypass this with test.currentTimeOffsetSeconds, however it seems to not work anymore.

I use Firefox for development because it has better tools than any browser I've use in the past, however this is a real blocker for me, since the sites I'm working on don't have DNS names yet and can't get updated certificates till then.

I've also manually added an exception in the certificate options, though that also didn't work.

Please guys, I've always been pushing people to use Firefox, though if it starts limiting my options without any way to bypass it if I feel I need to do something, then I'll be forced to go hunting for a browser that gives me more freedom, not to mention this is costing me work hours.

This problem is not the fault of Firefox, everything works great in vanilla Firefox (Iceweasel). My main browser is the 'Light' fork of Firefox, but the question should relevant to vanilla Firefox as well. The trouble seems to be that the project has stripped the "Add Exception" page of one of it's dependencies out of the browser.

My question is: Is there a way to add certificate exceptions to firefox without using the warning page? It would seem that being able to do so manually would be extremely advantageous for bulk setups and amnesiac machines. The only real in-browser configuration in Light is about:config and I didn't see anything obvious there, but I'm no expert. Is there a config file somewhere that houses this? Can I somehow import exceptions from Iceweasel?

This problem is affecting a page that I have to visit dozens of times a day at work and so I appreciate any help I can get. As it stands, I have to copy and paste the link and manually s/https/http/ which is quite annoying, but is still not nearly enough to make Iceweasel preferable, sadly.

Hi,

how to completly remove/disable web push notifications in Firefox?

about:config > dom.push.enabled > false

Not help with notif sent from "cdn . sendpulse . com"

The only alternative i have find is to block "sendpulse" using Adblock Plus.

Thank you.

I'm using Firefox ESR 24.5.0 on Red Hat Enterprise Linux 6.3 with GNOME 2.28.2.

It gives me that error when I try to view this image http://graphbench.org/images/hairball-header-cropped.jpg

It's only 1170x311 and 81.1kB so size shouldn't be a problem. When I ctrl-s to save the image, it opens fine in GIMP, Eye of Image viewer GNOME 2.28.2, and gThumb image viewer 2.10.11. Opening the image in Firefox from my hard drive fails with the same error. I have no extensions installed and it fails even in safe mode. The image loads fine in Firefox on a different (Windows) computer on the same network.

I've shift-refreshed to reload the image and that doesn't help. I yum uninstalled firefox, deleted my .mozilla folder, and yum installed firefox again but the problem remains. I went into about:config and there were no bold network.http.* prefs. The permissions for the domain are not restricted. I went to "Tools > Page Info > Media" and the image was not blocked. permissions.default.image is set to default. I "Allow pages to choose their own colors, instead of my selections above". When loading this page http://graphbench.org/ I get this error in the web console "[13:44:33.313] Image corrupt or truncated: http://graphbench.org/images/hairball-header-cropped.jpg @ http://graphbench.org/images/hairball-header-cropped.jpg" Four other images fail on that same page: images/nelson.jpg images/myers.jpg images/ceze.jpg and images/kahan.jpg .

Steps:

1. Video is correctly playing on youtube 2. Since I'm just watching and not pressing any key or moving the mouse, the display will blank for power saving after some minutes 3. I move the mouse to wake it 4. The video area is solid green, while the sound continues playing 5. If I switch tasks, the area from the other task gets painted over the video area, it seems like the video are is never refreshed after the suspend/wake

as the title says, i would like to hide scroll bar in firefox. I've searched the internet and found the following solution https://support.mozilla.org/en-US/questions/957337 but it seems not working anymore Firefox version that i use is (Nightly 61.0a1 (2018-05-04) (64-bit))

I am using Mozilla Firefox 3.6.3 on my computer. But a message keeps coming while I use Firefox saying "You may want to upgrade your browser. You're using an old version of Firefox that is no longer supported and may be insecure. To upgrade, open Firefox's Help menu and click Check for Updates..." But when I open Firefox's help menu, I can't see "check for updates" to click. What should I do?

Hello !

So I have seen this question posted before but the author decided to just switch version, which is not exactly a future proof solution

So Firefox changed the way ctrl-tab works to display the last tab used, and while I don't think this is a bad idea, I'm just very used to quick switching by mashing ctrl-tab/ctrl-shift-tab, and I don't really want to try and remember the exact order I used my many tabs to navigate between them.

Isn't there somewhere where I could toggle this ?

Thanks !

whenever I view a YouTube video on my linux box (Centos 5.8, fully updated) using Firefox12, YouTube always delivers the html5 video to me instead of Flash. This would be fine, but intermittently the video stops moving (while the audio keeps playing). I click the (I don't know what it's called) slider for the current position and the video will start moving again. until it pauses next time, anywhere from a few seconds to a few minutes. I don't know why it delivers html5 instead of flash, on my laptop using centos 6 and firefox12 I get flash video. Is there someway to configure Firefox to get flash instead? If not, I'd appreciate help in fixing the pausing video component.

I want to erase all certificate exceptions, that is, go back to the original default set of trusted SSL certificates. I've found the Certificate Manager and its big lists of trusted things, but I have no idea which of them ship with Firefox and which of them were added by me at some time in the past. How do I do this?

When one browses to a website, and it fails to load with the little grey label that says "A plugin is required to play this content", how on earth does one identify WHICH plugin?

I have been using firefox for years and have a system that work perfectly most of the time, and has all the usual suspects already installed. But when I see the message above, I just get frustrated because there is no link to follow, and so far as I can tell, no information at all to lead to a resolution of the issue.

Thanks for any pointers.

When I'm trying to watch some media files in Twitter, it says that it couldn't be played. At first I thought that I can fix it with installing flash player, but it didn't help. It works in other browsers (it did even before installing flash player). I'm using firefox version 57.0 and my OS is Ubuntu 15.04. Hope for your help.

I want to enable hardware acceleration in firefox linux x64 build

Mozilla Firefox 36.0.4

nvidia drivers version 331

THis is what I've tride http://askubuntu.com/questions/491750/force-enable-hardware-acceleration-in-firefox

Since sometime in October, 2013, I have noticed that more and more YouTube videos stop playing within a minute of starting. Most that stop do so in 15 or 16 seconds. The playing stops because the download stops. I watch this on a network activity monitor I always have running. Not all videos do this, but the problem is becoming more and more frequent. Some videos which played correctly for me in the recent past are now exhibiting this problem.

Other than installing the latest Firefox updates I have NOT changed the software on my machine. I run Linux by the way. I do not think this is a Linux problem because (1) it was all working before and (2) my son who runs both Mac OS X *and* Windows is also seeing the same problem. We both use Firefox as our browser on all our platforms.

I should also note that I am NOT seeing this problem with any of the other video websites I use, only when I go to YouTube. That leads me to believe that the problem is not in Firefox; if it were it should affect videos from all websites.

Additionally the problem occurs whether or not I log into YouTube.

I have not run Firefox in safe mode because all the extensions I use did not affect the download of Videos before, so I don't expect unchanged extensions to suddenly start causing problems.

So, anyone else see this problem? (There was another note which talked about the same problem but it was disabled.)

Also -- pardon my paranoia, but -- I need to ask: Since YouTube is owned by Google and Google has its own browser it wants you to use, Chrome, is it possible that Google is intentionally causing some YouTube videos to fail if it sees that they are being sent to Firefox?

(That is not so outlandish I think. Microsoft WAS at one point caught mangling web pages going to certain web browsers other than IE. And these days Google wants to dominate the Internet just as badly as Microsoft does, so why not pull dirty tricks too?)

If this keeps happening I am going to have to try Google's Chrome to see if it somehow manages to play YouTube videos correctly while Firefox does not. But I really do NOT want to install Chrome because I trust Google about as much as I trust Microsoft, which is to say Not At All.

Thanks in advance.

Pages with web fonts, like http://google.com/fonts, are not rendered correctly. All text that should be web fonts is shown with the default font. This is Firefox 20.0 on Ubuntu 13.04 with Gnome 3.8. - Starting in safe mode does not help. - neither does starting with a new blank profile. - There are no error messages in the Error Console. - Javascript is enabled. - not allowing hardware acceleration does not help. - the "Allow sites to use their own fonts" option is checked. - I am not behind a proxy.

What else is there to check?

After updating to Firefox 46.0 in RHEL 6.6, when I launch I get the following error: XPCOMGlueLoad error for file /usr/local/firefox/libmozgtk.so: libgtk-3.so.0: cannot open shared object file: No such file or directory Couldn't load XPCOM. I tried to install any package gtk3 or similar, but only find gtk2 and gtk+ are available in Red Hat, and I have already installed. I downgraded to 45.0.2 that works fine. Thanks.
