Hi, Happy New Year!

Finally I took a deep breath and hoping for no major surprises and bugs, I finally updated Firefox to the latest version.

I have a few questions:

1. As advised, every month I backed up info in the profile, following https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles Is there an up-to-date version of these instructions as the prior ones no longer work (menus were changed, Troubleshooting works differently, etc.).

2. Does the "Allow for session" option for cookies work and if so, what does it do?

3. Is there a way to change the way the TABs look now (washed out, white, very hard to see and differentiate, hard to see which one is the one I am looking at). I am wondering what is the perceived benefit of this change. In the old version I had, the tabs very clearly delineated and easy to see.

4. Where can I find a listing of the enhancements and major changes of the versions released since mid year 2021, from an end user perspective?

Thanks.

why is FireFox 95 opening multiple windows on startup with Windows 10, Roboform, & Norton 360? FireFox is set to open a new tab, not new windows, so I do not know why it is doing this? I see lots of people asking this question, but there is no guidance online. What is up? This is causing FireFox to use way too much resources, and slows the computer.

(SECOND occurrence of this problem; not sure HOW previous instance resolved - my short-term memory ISN'T the best at present!)

Have taken all recommended steps short of completely refreshing (renamed a file titled 'config.json.old' as it was the ONLY one with a 'json' filepath suffix) because I don't want to have to relocate (another) existing session / configured profile by trial & error if avoidable - 'cookies' were removed along with history / cache cleared; reset / deleted related browser registry entries as directed, activated ' Troubleshooting / Safe Mode' contingency and STILL can't download anything (additionally, tried to do so with and without limited-time Malwarebytes web protections).....want to CONTINUE using Version 95 because by ALL indications and from what I'm seeing in Comments, my instincts about newer ones - were sound, WELL-informed.....please advise ASAP? Thanks!

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.

Firefox crashing when rendering maps

For the past two weeks, I've noticed that embedded maps make my browser immediately crash. I initially thought it was a Firefox problem, but I have been having a similar issue with Safari. This does NOT happen on my iPhone using the same two browsers. This also does not seem to effect Google Maps or embedded Google Maps, but embedded maps from other services. Anyway, I'm posting here because Firefox conveniently provides crash data, I'm not sure what else the cause could be and I'm hoping someone can help.

Two websites this has been consistently happening with are The Empire State Trail bike path (https://empiretrail.ny.gov/) and a NYC vaccine finder website (https://vaccinefinder.nyc.gov/). Firefox immediately crashes, though with the EST website it seems to be tied to the pathway of the trail being drawn (crashing after I've zoomed in a few times and the path has to regenerate). Safari doesn't totally crash, but forces a site reload and after it fails a second time says it can't display the site.

Any ideas what the issue could be? I'm on the latest version of Catalina (10.15.7), Firefox and Safari and seem to have all security updates for all.

Here's a link to the latest crash data: https://crash-stats.mozilla.org/report/index/1389c870-51cf-4790-b0a0-fd01f0211202

Hi, The program SEEMS to start but Firefox does not load one singel page. I get no errormessage but firefox does not even try to open pages.

Also, if I try to go into "settings" nothing happens (no errormessage, but settings does not open).

I have tried to uninstall and reinstall Firefox. Does not help.

If I try some other bowser everything works fine. The problem started after I did a total uninstallation of Office365 (does not need to be depending on it but it could be a connection).

Have searched the web without finding a solution and now I ask for help here, I really do want to keep using Firefox but currently it is impossible.

email from mozilla@email.mozilla.org

For real — it's terrifying how much we don’t know about Facebook. The social media giant has almost 3 billion users (and tracks many more), but this year we've seen yet again how the secretive way it operates is dangerous for all of us.

By keeping us in the dark about how it combats misinformation, who's paying for ads and how social media affects our mental health, Facebook actively stops us seeing when it’s causing harm.

But here’s the thing: we're not going to just accept it.

It's true — Facebook's secrecy puts us all at risk. To keep us safe, we urgently need it to be open and accountable. Chip in now to join the fight, it takes 1 minute:

My Firefox bookmark menus are often taller than my screen.

When I select a bookmark well down in the current menu by typing a letter, for example "T", the menu display scrolls down to the first matching choice, but that choice can be mostly covered by the down-caret indicating more choices further down. I can see the top of the highlight for the current choice, but I can't read the text of the choice.

Not a big deal, but I'm hoping it's an easy fix. Thank you!

Firefox v90 on a Mac. Continual nag screen popping up telling of an update. None of the solutions presented by top contributors or moderators work. Nothing obvious or suggested in about:config. Nothing about putting policies in .json files in the correct directory.

It is as if Mozilla refuses to let you turn off that nag screen.

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

  1. I've performed a completely clean uninstall of Firefox and then reinstall
  2. Cleared all browser history/cache
  3. Removed all extensions
  4. Disabled IPv6, HTTPS Over DNS, No Proxy
  5. Ran through Firefox's troubleshooting
  6. Used Firefox Troubleshooting Mode in the Browser
  7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

  • Windows 11 21H2 2200.348
  • Network driver is the latest Win11 edition

Hi all,

Since I switched to Win 10 Firefox constantly crash on my computer.

  • Tried fresh install no change
  • Tried repair no change
  • Switched off extension and then on (one by one) no change
  • Deleted cache - History - etc .. :( it worked for only a few days since I did a full scan with Microsoft Defender.
  • Since this last crash (as I could not launch Firefox anymore I used shift + click on Mozilla shortcut)I decided to switch off the graphic card acceleration and all the other option in this menu and it seems to help

Could you tell me how to send you the crash report ( I do have 8-10 of them already sent to Mozilla)

I have had this issue before and uninstalling and reinstalling has fixed it in the past. Today when I opened firefox it prompted me to update , which I did without thinking. Subsequently, it stopped working. I have tried: restarting my PC, running in troubleshooting mode( it wouldn't even open when I tried this), uninstalling and reinstalling using the internet installer, uninstalling and reinstalling using the offline installer ( tried on multiple hard drives, so I don't think hardware failure is the issue), installing an older version of fire fox, and installing the 32 bit version instead of the 64 bit version. The attached images show what displays upon trying to launch firefox. nothing loads, not typing an address into the search bar, not clicking on a bookmark, the only UI element that will display is the 3 horizontal line setting menu.

1- I've tried several webpages. They all work well until a reCAPTCHA pops up, the tab crashes and creates a dump file 2- I tried uninstalling Firefox, including erasing profiles and all Mozilla folders then reinstalling, and selecting refresh. It sill happens. No addons or extensions, and HW acceleration on and off 3- The problems goes away if I run Firefox on Troubleshooting Mode

Version is 94.0.2 (64 bit) running on Windows 10 21H1 on an i7 1165G7

Am I missing something? Is there a way to do a cleaner install?

Thanks for the help!

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 I check the crash logs, it shows in most of them: Modules - Filename: umppc14210.dll Version: 6.28.14210.0 Debug Identifier: B9143DE260194C88AB48EFD6782C9EAF1 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

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.
