since update I can't open you tube videos, site is working & can search get previews but when click to open it don't play only try to load & keeps spinning circle on black background. Cleared cache & cookies, deleted temp files, refresh Firefox but no help. Not using any add-on other than anti virus (updated), no plug-in used. No issue with other sites only concern is you tube video not playing. However, in private window video is playing without any problem. Other browser working fine, facing this issue after latest update - 77.0.1 (64-bit). No issue before update.

On saturday our global sertificate expired and we renewed it a bit late. Now Firefox users cant visit our site, seeing this error message.

   Secure Connection Failed. 
   Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number.
   
   Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL 
   
   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. 
   Please contact the website owners to inform them of this problem.

Unfortunately the only way to fix it we found is deleting the whole profile, deleting the sertificates themselves does not work for us. It is very difficult for our users to do it. Can you please help us with this problem?

Hi Support,

since few weeks I am unable to use any Firefox version (from older to the newest) with Windows 10. The issue is really weird because I can start the Firefox application; however, I am unable to connect to internet and I cannot open many Firefox pages like Options, about:config, about:support, Help> Troubleshooting information, etc.

The issue occurs for both standard Firefox installs and with Portable Firefox installs from different sources (Portableapps.com, Winpenpack, etc.). Restarting in Safe Mode has not helped.

I am looking for suggestions on how to troubleshoot this issue and hopefully solve it, as Firefox is my preferred browser.

Thanks in advance for any help you may provide! Best regards, Viki

Hi everybody, I'm running Firefox 77.0 on my 2014 rMBP with OSX 10.11.6. A few hours ago my OS crashed and I reset my computer. Once I did this, I opened everything back as it was pre-crash and all my Firefox tabs and absolutely everything else loaded correctly except for my history.

Every time I type a word, no previously visited URLs will load up in my URL field, I checked my History and it seems to have deleted 99% of every site I've visited. The recently closed tabs and windows are still there, and I can reload them if I press cmd+shift+t, however the rest of my actual history seems to be gone. I've reset (normally) my computer a couple more times, repaired disk permissions and whatnot and for some reason it won't even save whatever other sites I've now visited since it was wiped. Am I screwed here?

FF didn't used to be so slow. It now get really slow and uses a lot of RAM to the extend that my disk is full and I have to shutdown FF.

I do have like 30 tabs open, with one or two Slack-like web apps. However, I'm not using them all at the same time. In the first couple of quantum releases it didn't used to be this slow, never mind pre-quantum performance. Oh and I'm not gonna compare to Chrome or Chromium.

Any help with this? Is it the extensions causing it?

  • Also I never found a proper replacement to legacy Tab Session Manager (the quantum one is no where near as good).

Hello,

Sometimes Firefox is having a wrong IPv6 in cache. Using the extension SixOrNot, I can see for rss.forumanalogue.fr the following IPv6 2001:41d0:fecf:8900:216:3eff:fe65:97bc, with the note "Cache". However, this IP corresponds to toot.forumanalogue.fr and the actual IPv6 for rss.forumanalogue.fr is 2001:41d0:fecf:8900:216:3eff:fef1:20a2. In order to temporary fix the issue, I perform a dig and it solves the issue for a while.

It is a rather new issue (few weeks).

What is going on?

Hello,

One of my last Crash ID report : 49e3c347-5deb-4659-b9d1-281b00200514

I experiment this problem on two of my computers. Both are running Debian Buster. If I don't forget to quit Firefox before shutting down my computer, then I believe I won't have problem the next time I switch on my computer and launch Firefox.

However, as most of the time, if I shutdown my computer with Firefox still being open, it seems that Debian Buster doesn't close properly Firefox. In fact, if Firefox was still open when I switch off my computer, I can be sure (100% of the time) that at the next startup, Firefox won't be able to launch the previous session and I'll have to "restore my last tabs".

No other software seem to suffer from the way Debian Buster switch off. Only Firefox.

Thank you for any help one could give me,

Regards, Thatoo

  6. downloaded a fresh 76.0.dmg from the website
  7. Problem persists. Application does not load, "Profile missing" opens immediately
  8. No application support data in /Library/ application support/firefox exists

Chrome works and Safari works no problem.

About 1 in every 40 or so times that I try to drag the vertical scroll bar with my left mouse button, it acts like I have clicked UNDER the scroller and starts scrolling down quickly until I release the mouse button. This NEVER happens in Chrome or other programs. It always works properly the next time I drag it.

Potentially related: About 1 in every 75 or so times that I try to drag the vertical scroll bar with my left mouse button, the scroller doesn't stay under my mouse cursor. It moves about half as fast. This makes it impossible for me to scroll to the bottom of the page because my mouse cursor gets to the bottom before the scroller, which means I have to let go and grab the scroller again to finish scrolling down. The scroller always stays with my mouse cursor on the 2nd attempt.

I've attached a pic showing what i'm calling the "scroller"

I have a few special buttons on my keyboard (Calculator / Mail). I've set them (on lxde-rc.xml) to run a simple bash script (Volume up / down using pactl). Unfortunately, I've noticed that only on Firefox hangs when I press these buttons (tested with terminal/slack/IDEs/Chrome, no issues). It's a ~2 seconds hang that prevents me from doing anything (tried scrolling/typing/clicking, nothing).

Any way to see what is actually happening / disable this behavior?

Hello,

I love Firefox. Thanks for making it and please keep up the good work. I used Firefox for years, switched to Chrome for about 10 and have now come back to Firefox again. Love the browser.tabs.unloadOnLowMemory config option. This was crucial to me returning to Firefox and I suggest you make this the default.

Anyway...

The issue I'm writing this for is that Firefox seems to be preventing my computer from sleeping. When I run

powercfg /requests

from a command prompt run as administrator, I get the following info: SYSTEM: [DRIVER] Realtek High Definition Audio (HDAUDIO\FUNC_01&VEN_10EC&DEV_0255&SUBSYS_10251259&REV_1000\5&26841d0a&0&00) An audio stream is currently in use. [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe

This seems to show Firefox running audio that is preventing the computer from sleeping. However, none of the tabs are currently playing any audio. Thought I'd report the issue here.
