Hello,

I have a PC with Windows Seven, and a local network 1Gb/s (wired, no Wifi) with a NAS. When Firefox is open, the speed of my local network slow down. It takes about 30 seconds to open a big picture on the NAS when Firefox is open, and 0.5 s when Firefox is closed. Same thing for video. I can't read a video when Firefox is open. With Chrome or other browser all is ok... Firefox version is 91.0.2 64 bits, but same issue with previous version.

I have made a new profile, a new install of Firefox, shut down my firewall and Antivirus, Opening Firefox in safe mode, repair Firefox, but no effect...

Any help will be extremely appreciated!

Thanks!

This the second time I am entering this problem -- the first time Firefox refused to let me return to this site.

First, I am running Firefox on Ubuntu, but Ubuntu is not relevant because the same issue occurs in Windows.

Whenever I access a file, for example, one at https://species.wikimedia.org/wiki/Chioneosoma, its color (which is programmable) changes from a light bluish green to a deeper violet. Where is this color-difference stored? I have thousands of WikiSpecies files I have accessed, and they all show the violet "accessed" color if I ever have opened the file to read its contents. The problem is that when Ubuntu has to be reinstalled, I can add references to all my files, but the color-changes seem to be lost. This is a serious issue, because I currently have over 50,000 files referenced (and saved in my directory file:///home/jwill/Documents/WikiSpecies/Animalia_Plantae_8) and am still adding to them!

I think the storage location must be somewhere in one or more of the following files ('_' replaced '/'):

   _home_jwill_.mozilla
   _home_jwill_.cache_mozilla_firefox 
   _home_jwill_.cache_MM_firefox
   _usr_lib_firefox

Can you please tell me where the list of accessed files is stored? Whenever I enter a referenced directory, to access it, the color changes; so, Firefox must be able to store a reference to each new referenced directory name.

I am using Linux Mint 6.0.3.1 , and my Mozilla Firefox version is 77.0.1 . My Firefox will not update, neither automatically nor when prompted. When I go to all the pages for downloading and installing the newest Firefox, I am always able to download a package, which appears as a folder labeled " firefox-89.0.2.tar.bz2 " but then I cannot install it, it just appears as a folder full of files that will not run. I have tried following the command lines in the terminal that these pages claim will make the new version run, but I always just get a response like "no such command" or "no file exists." Shouldn't there be some relatively simple and reliable path to just get firefox 89 onto my computer?

Hi All,

My web pages have 4 basic sections, Header, Menu, Content and Footer. In the print media query position static is used. I understand that should make them print in order. All browser had this messed up for many years but I'm sure Firefox had this fixed for awhile. In version 82.0.3 this is messed up again, footer prints at the top of 1st page.

Is this a printing bug? Or, do I misunderstand position static?

Why can't it print as shown on screen, What you see is what you get?


Thank you for any help,

Charles

I can find no recent documentation on command line options for the Firefox Browser. All of the information on this appears to be out of date or just does not work any more (in the latest version June 2021). Is there any documentation on this anywhere that is correct for the current version of the browser? I am specifically trying to run firefox with command line options on Windows 10 but I do not see that that should make any difference. The only option I can get to work is starting firefox with a specific URL; even then I have to change the browser settings to get that to open a new window; because the browser settings override the command line option -new-window

I'm running 96.0.3 on a fully patched Win 10 Pro system - both O/S and programs. When Firefox is running I'm getting these pop-up error messages randomly with changing content. They stay on screen for some seconds and then go away. Message states it's from (via) 5.back2yard.biz. I put that in my hosts file and I'm still getting them. My network is a cable modem hooked to Xfinity and then cable connected to another fully newer patched router. All addresses are 10. range. I ran both a Malwarebytes scan and a Windows Security scan - both are clean.

I'm unable to upload a small image after a hour so I'll give up on that right now.

Firefox will start once (maybe) and then it makes no difference where I click from (tray, programs, desktop shortcut) Firefox refuses to boot up. I've tried re-installing multiple times. If I reboot, it will start. Also sometimes I will get a New tab but the page/URL never comes up. Firefox just hangs. I'm running Windows 11.

Since a few days, I keep experiencing constant crashes with Firefox.

In the most common way, a Tab will crash first, often followed shortly by the whole browser crashing.

Crashes occur on, but are not limited to, following pages: • YouTube.comReddit.com • Google Account Login • about:preferences • about:crashes • about:support • The very same Support-page I’m writing this on

Crashes still occur after: • Rebooting Computer • Clearing of Cache • Starting in Safe Mode (crashes in Safe mode) • Deactivation of hardware acceleration • Refreshing Firefox • Reinstallation of Firefox (Uninstalled with the Uninstall/helper.exe) • Use of Windows Deployment Image Servicing and Management tool (DISM /Online /Cleanup-Image /RestoreHealth)

Crash logs list: • Crash Reason EXCEPTION_BREAKPOINT Crash Address 0x00007ff88082381f • Crash Reason EXCEPTION_ACCESS_VIOLATION_READ Crash Address 0x000001f4465fffe8

I’m kind of out of options. Most support pages are 2 years or older, so I don’t really know if I’m experiencing the same errors as they did.

If there’s any more information required, please let me know.

I'm on firefox 90.0.1 on Mac OSX Big Sur 11.2.3. When I try to delete a site certificate that I have (that is about to expire), it appears deleted, but when I open the certificates page again it reappears. When I restart Firefox after deletion it reappears. When I delete cert9.db from my default profile after closing firefox, and then reopen, it still reappears. When I uninstall Firefox, delete the default profile folder from App Data and the Mozilla and Firefox folders from my caches, it still reappears (I also deleted the update folder).

I am doing sync between this mac, my phone, and another computer, but I ONLY have bookmarks, Add-ons, and history. Might the sync be also syncing my certificates?

Help/tips would be appreciated.

Hello! I am in a work environment and I am trying to determine if there is something in our security systems that is preventing Firefox from running properly. Once Firefox is installed, it works the rest of the day with no issue but almost daily the morning after, it will start to open then instantly crash.

When using the dark theme from Firefox, Google searching seems to break completely as well as some pages will not load which may be related to this.

I have already tried uninstalling Firefox, deleting all of the folders, then reinstalling with a freshly downloaded installer (Even tried the beta one) with same results. It seems potentially MAYBE related to how long ago I closed Firefox before I shut down (Like Firefox is trying to save something to a secure location and times out, then it will work but if it hasn't timed out, then it crashes... or this is my guess)

The Signature seems to change randomly for the crash between crashes.

I really am tired of constantly reinstalling Firefox but I do not want to use Chrome or Edge unless websites require it.
