Firefox Support Forum

Its very annoying and i cnt find nothing similar to that problem on the internet. I dont know if it is related to adblock plus 2.6.3. extension on my browser or not. Yeah,and after mozzila opens that blank new window it goes to that link i clicked on (no matter if i clicked new tab or not)...so i can browse the internet but new blank windows are piling up and as i said...its very frustrating

After FF rebooted to install FF 30, I noticed that all traces of Roboform are gone. That is, I have no right-click options to fill forms, etc and there no longer is a Roboform toolbar. I do have a Roboform icon in my systray, but it does not do anything with FF.

I tried a bunch of the usual suspects like doing away with Roboform integration with FF and then re-enabling it, FF reboot, computer reboot, etc. No go so far. I did a search of the issue and it does seem that this may be a known issue. I am running Win 8.1/64-bit.

Another poster says he received this response from Roboform:

"leave RoboForm toolbar on a separate line where it was installed initially to make it work in your current version of FireFox."

I have no idea what that means. Can anyone explain or otherwise help with this problem? Thanks in advance.

When I am on EBAY (or other sites for that matter) in the area where there should be pictures, I get a message saying: Image not available

This just started a week or so ago. I am able to see the pictures fine using other browsers, but not Firefox. Any suggestions?

After upgrading my FF to the latests version 30.0, those button (Minimise, restore and close) on the top left conner was gone, when I've maximised the FF windows. and the blank black space wont respond for any actions. I'm using a Windows 7 ult +sp1 with all Windows Updates.

I right clicked on the blue star and I clicked something like "delete bookmarks". I thought it would remove the single bookmark and not the entire toolbar. How do I recover the toolbar? PS, you guys should have a confirmation button.

This is happening on our internal websites that used to prompt a window to enter your credentials. This is no longer happening.

It just immediately gives us a

401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied.

I recently experienced that the You Tube player automatically became large.

The standard size for YouTube videos seems to have changed from their old standard into the size that used to be halfway between normal and fullscreen.

That is WAY too big, and it's actually disgusting to look at with 360p and below videos. The vast majority of videos look like crap when they're stretched out.

There is a new button, "centered player," where the old "large player" button used to be. Clicking on it will center my enormous window, then that button displays "default player," which brings me back to this large, uncentered player.

This is happening with Firefox, with IE working fine.

Although I am technically incompetent I tried a few suggestions:

Remove all cookies Hit Ctrl+Shift+K and insert the code below in console:

document.cookie="VISITOR_INFO1_LIVE=; path=/; domain=.youtube.com";window.location.reload();

However, I am getting the following messages:

Use of getAttributeNodeNS() is deprecated. Use getAttributeNS() instead. util-service.jsm:590 Use of getPreventDefault() is deprecated. Use defaultPrevented instead.

And it is not working, back to same Large Player….

Hopefully Mozilla can do something to fix this.

Thanks!

Every time I attempt to watch a youtube video I get a crash report. I have tried to install newer versions of the player and I still get the same result. What can I do to solve this issue?

Since the last updates Firefox client has a memory leak issue.

My habit is to open a high number of tabs. Never had any problem until the latests release. The tabs don't seem to free up the memory when I close the tabs. For example the client reached ~2Gb of RAM, the usage remained the same even if I closed the tabs. I have to use the Free memory utility from about:memory page to keep the old behavior.

Also the memory seems to build up if I leave the client open for an extended period of time. And when the computer enters sleep mode, I have to restart the client. For me this is an old issue but it gets worse every release.

I have tried most of the solutions presented but none of them work. I'm also aware of the link from the forum which gives some advices to lower the memory usage.

At work I have Chrome installed and seems to work better. The home computer is better than the one from my workplace and I have more or less the same plugins (Flash, Adobe, Java, etc.) So I assume that the browser has something to do with it.

Any ideas what could keep the browser from cleaning up the memory? The memory seems to be freed when GC is used manually.

I am Using the new HTML 5 Player when watching Videos on Youtube. It works just fine when media.mediasource.enabled is set to "false" but then I cannot get the full experience because the lack of features!

If I enable it, NO Video is going to load, meaning I cannot watch any Video on Youtube! As a workaround I installed the Plugin "Youtube Control Center" (missing in your List below). But it would be nice if I would NOT have to use this...

Even better would be if Firefox would Support WebM. But this does not seem to be the case since YT uses exactly this Format with its new Player... (And if I enable this media.mediasource.enabled (set it "true") NOTHING works anymore.)

Hi,

After an apt-get update, sites that use HTTP authentication do not prompt for credentials and go straight to HTTP:401. It is only affecting this browser, others have no issues. I also updated a FF in Windows, no issues there after the update.

No other browsers are giving me this error.

I'm using Windows 8.1 x64 system. The issue seems to be only on the sites I mentioned above, since all other video sites(random sites using Flash,JW player;Yahoo! videos, Daily-motion) are working. I've tried clearing cookies,cache but nothing. I reinstalled Firefox and no change. I disabled add-ons and running in safe mode but didn't help. This problem seems to be happening with IE and chrome, but only for kissanime.com. YouTube works for them as they use html5 by default. Also the embedded YouTube player on sites(like Facebook) don't work but the native player for Facebook videos(when we directly upload to FB, it uses native player), then it works.

Firefox wouldn't open some swf files when I tell it to through any means. However, http://edmullen.net/test/poopboy.swf works fine.

I looked in my Options -> Applications menu and found this http://i.imgur.com/kPVOHdE.png

So its got 2 different types of swf files its encountering. I cannot tell the top one to affliate the same way the bottom one is.

I tried uninstalling the plugin. This removed the bottom one and meant that the poopboy.swf I linked also didn't work in the same way, however, reinstalling it got me right back to square one.

I'd like to add that these particular .swf files I'm trying to run DID work just yesterday so file corruption is not the problem, especially as I went and redownloaded all of them.

Hello, Firefox was fine last week now it tells me the following for sites like Facebook, Google, etc

www.facebook.com uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer)

On some I cannot bypass.

The problem is I'm using Microsoft Family safety and the certificate issuer is now: Microsoft Family Safety.

I don't know if this is caused by a Firefox update or Microsoft update, but either way Firefox now does not work, I cannot fix it and I'll have to stop using it unless there's a solution. I imagine the same fault is happening for anyone else using Microsoft Familty safety.

I also use Chrome, which is even more pedantic about certificates, but Chrome works perfectly, suggesting it's a Firefox update that is shafting this.

Any idea?
