Firefox-Hilfeforum

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.

Find that some (not all?) embedded videos generate the error code and do not play. Here's an example:

However, this plays in Slimboat and Chrome.

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 !

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.

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

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'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 .

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.

I want to enable hardware acceleration in firefox linux x64 build

Hi,

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.

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

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.

Hi all, so since a few versions I have noticed a difference in video buffering. Firefox now buffers a very small amount of a video, like it does when mediasource extensions are turned on. I did turn them off however so videos were usually downloaded automatically all the way, which was very convenient for me, instead of just when you play the video the next few seconds. This doesn't work anymore as if I enabled mediasource extensions and every video used it.

Is there some way to revert that behaviour? I guess it was done out of performance reasons. How can I change it back, e.g. make the video buffer bigger?

Thanks a lot

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?

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.

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.

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.

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?
