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
• Firefox 95

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

I can not understand why my laptop has suddenly decided to not download

when I download from firefox or save a picture from gmail firefox says failed

sorry I am a 73 year old dummie

Ok, this might be REAAAAALLY weird that i'm talking about a firefox version that was released in 2012. But i really need it on this windows 2000 VM. The problem is firefox 9 - 12 is not loading any websites or webpages. It crashes instantly upon opening them. Versions lower then firefox 9 - 12 work flawlessly. Probably nobody will answer this but it is really important for my VM.

I am an elder person with the usual deficiencies of age - 86 years - and this is difficult to tell - I found it hard to see s since my first pc in 2003ome text on my screen here - and was given the option to choose DARK or LIGHT - I chose dark and this certainly improved matters on Firefox - because I have chosen firefox since my first pc in 2003 over night - last night - the themes have gone back to dark with all the attendant problems which I HAD before I chose LIGHT - can someone please tel me how to get light back I had volunteerd service but I do not think I have much to offer and that - too - is what I want to amend

I have reinstalled my home computer and reinstalled Firefox, logged in and synced. My passwords from my work browser's Lockwise have not appeared or synced. Please advise. Thank you.

I know patience is thin. Feel free to cut to the chase. I did try to self serve and only found export then import options. Are my expectations for sync incorrect?

Happy New Year.

Hi I went to my email provider earlier on and Firefox froze saying that a copy was running and to close - which I did. But Firefox will not access any website: just the normal waiting message.

I did a hard reboot. No joy. I tried a download. No joy. I am using Brave at present to access you. Everyhting else, email etc is working fine.

Any advice please.

while using any firefox addons for speeding up a video higher than 4.0 of original speed the video sound suddenly goes off by default. in other browsers such issue does not appear. only in firefox. what to do?

My Firefox browser recently upgraded to 96.0.1 (64bit) and since then I have noticed that the background on when doing google searches and when watching Youtube is in dark theme. Altering to the light theme in Firefox settings has no effect and I have tried all the suggestions without success.

I did find that by removing the theme Unicorn Fantasy by M♥Donna and installing a light grey theme this forced google and youtube into there light theme. I have also tried installing other themes and these also seem to cause the dark mode.

I would assume it is a problem caused by the latest Firefox update as google and youtube had the normal white background before this. It's not a massive problem, just annoying and makes little difficult to use

Anyone know how to get round this ?

Hello there !!!

Today I had serious damage to my Mozilla Firefox. When I started up Firefox I realized that I lost all my opened tabs on all my (three) opened windows, although I had checked the box "Restore previous sessions" in the settings section.

I opened "settings" and I saw this box unchecked !!!!!

The unfortunate event of this failure is that I restarted Firefox and even worse I restarted the PC.

Now I wonder, after all these, if there is a way to restore all my lost TABs that, I believe, there are hidden somewhere...

'Release 96.0.1 Does Not Work with Our Ariba PunchOut Catalogs' Users can punchout and add items to the Shopping Carts, but when they try to return the items from the cart back to our local Ariba Application, users receive a "Token Expired" error. When they click the button to return to the Ariba application, there are no items in the requisition.

We experienced the same issue when Chrome released version 80 in February of 2020. We have been recommending Firefox as the preferred browser but now it has the same problem.

Can you provide some way for users to run an older version of Firefox? Version 95.0.2 Works great. I have not upgraded to 96 yet due to this issue. However, many campus users have already installed 96.0.1.

Currently in our environment, only Inernet Explorer or EDGE running in IE mode work with our Ariba Application. Should we advise our campus users stop using Firefox now?
