After installing update for Windows 11 23H2, Firefox would run but could not display pages. I tried re-installing Firefox with the online installer but it can't complete the installation and no Firefox.exe can't be found. I then tried downloading and installing the offline version. The installation appears to complete but Firefox doesn't launch and Firefox.Exe can't be found in C:/Program File/Mozilla/.

The True Key extension from McAfee cannot be installed on Firefox. I have the latest updated version of Firefox 133.0.1 64 bit on my desktop Dell computer running Windows 11 Pro. When I try to install the True Key extension, a message pops up advising me that the extension cannot be installed due to a Firefox policy violation. I have reported the issue to McAfee for their action. Photo of the pop up message is attached.

Firefox crashes every day or so on my home computer. The most common error message is "kmode exception not handled." I've tried the suggested fixes. Nothing helps. The crashes are not being recorded in "about crashes" or in %APPDATA%\Mozilla\Firefox\Crash Reports\. So it seems the crash reporter has to be fixed before the problem causing the crashes can be identified. Firefox does not crash on my office computer and no other program causes my home computer to crash. Thank you.

Ok, this is a weird one.

I can't load https://duckduckgo.com. It breaks search in a new tab, but I also can't visit it directly from the url. The tab simply does not load.

I've cleared cache, cookies, and extensions. I've refreshed Firefox more than once.

I can visit https://html.duckduckgo.com. I can visit https://lite.duckduckgo.com.

However! In a private window, I can visit https://duckduckgo.com It still breaks in a secondary normal window.

No other site appears to be broken.

Hello,

I checked the troubleshoot and gave all the necesarry permissions on my Mac for Google Meet to use my screen (allowed audio, video and screen recording). Nevertheless, I cannot manage to share my screen on Google Meet. As shown in the screenshot, it offers the option to share my whole screen (I cannot select a window or a tab...) but for my audience neither this is working.

Could you please help me fix this?

Many thanks in advance!

Where possible I prefer to sign in using a passkey (stored on a USB key). I use a password manager for the rest, and have thus disabled password saving inside Firefox.

However, when password saving is disabled, Firefox will not prompt for using a passkey when inside a login field, this works when I re-enable password saving, but that leads to other annoyances.

Is there a way to enable passkey the passkey option without also enabling the password saving?

I have a question about using Firefox PDF Editor. I copied some text from a PDF document that is on my computer, by highlighting the text and then hitting Ctrl+C. The text copied onto my clipboard OK. Then I opened a blank PDF document in the Firefox PDF Editor and tried to paste that text into the blank document, but I wasn't able to do so because when I right-clicked on the blank document and then clicked on "paste", nothing happened. This apparently is because the word "paste" is faded-out in the drop-down menu (i.e., it does not appear in prominent bold print). Google's Artificial Intelligence seems to indicate that the technique I used would work (see screenshot which I've uploaded). But it didn't work, so can anyone please tell me how can I paste text into that blank document?

I can't watch Twitch live stream and videos after updated.When I watching live stream on Twitch, the stream start showing some old tv effect but in colours green. I thought was Twitch problem, then I changed to watch video from my college by using their website. But it still has that effect. But I can watch Youtube videos with no problems. Then i changed to use Microsoft Edge to watch Twitch, surprisingly with no problem. I already updated to the latest version in Firefox. Can anyone help me Please. Thank You

Hello, everytime I try and upload a video on YouTube with firefox, the video gets stuck at 0% processing,

This never happened in my 4 years of youtube and recently (a few weeks ago) this starting happening. I use firefox to stricly upload videos, and use chrome to browse with my other account casually.

Now Im forced to upload using chrome but I want to still use Firefox to upload videos. anybody know why this is happening? I've cleared cache serveral times and it still won't work. I have no adblockers etc.

On Feb 13th I went to my website at MyHeritage.com, to which I'm always logged in, to find that a few seconds after it loads it becomes all greyed out and I can't access anything. I had been on the site a couple of weeks earlier with no problems.

I removed the "Enhanced Tracking Protection" and I turned off AdBlocker for the site but the problem persists. I have logged out and then logged in - same problem. I turned off my computer and restarted it - same problem.

When I went to log in to my account at MyHeritage using my Chrome browser I encountered the same problem of a greyed out page BUT there was a banner stating something about cookies and when I clicked the "I understand" button the greyed out page cleared and I was able to access my account.

However, Firefox is my default browser and I want to be able to access this page using Firefox. It seems to have something to do with cookies.

Hi team, I have created a web application using angularJs(angualr 1) and html in which a web page displays google map.it is working perfectly when we open in Firefox and chrome browse. I have created a wpf window application using .net framework 4.6.1 and embedded geckofx control to render web pages from web application .Issue is that google map is not rendering in the gecko browser embedded in wpf application , Although other contents/element except google map components of the same page are getting displayed in the geocko embedded wpf control(WindowsFormsHost). But when we open the same page in Firefox browser ,it is working fine. It seems like the issue might be related to how Geckofx handles certain JavaScript or rendering features required by Google Maps. Is there any configure or setting that is require to be set in geckofx to get the google map displayed ? or is there anything which is not supported by geckofx ?

For whatever reason, when I open certain websites in Firefox, it shows the prices in UK currency including VAT, but when I open the same websites in Chrome, they show up in US currency. The Windows region setting and the VPN connection is the exact same for both. The difference is the browser.

Is there some setting in Firefox that makes it think I am in the UK, and if so, how do I change that?

Hi. There is a new feature of Firefox that bothers me. It is when I drag tabs around the top, they try to group when I don't want them to. So I go to about:config and find the "browser.tabs.groups.enabled" key and set it to false. But when I restart Firefox, the change reverts. How do I fix this so the change stays?

I've already tried going to Menu->Help->More troubleshooting information->Profile Folder->Open folder, but there is no "user.js" file there. Do I have to do a Firefox reset to fix this? I hope not...

Note that I'm pretty sure that other settings that I change do not revert when I restart Firefox. Right now, it seems to be just this one about:config setting, unless the new version of Firefox reverts all manually changed about:config settings upon restart.

Thanx in advance for any help.

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:8080.

   The site could be temporarily unavailable or too busy. Try again in a few moments.

Since April 5th I have lost spell check in the message pane of the emails I type on outlook.live.com It still works in the subject line, but not the message area.

Windows 10 pro 22H2 updated to end of March, when spell check was still working well. Firefox 137.1 English Canada Language selected (has worked well for years)

I go to outlook.live.com to read and answer my @hotmail.com emails.

When right clicking on a misspelled word in the message area I get only these options, Firefox does not give me the usual options.

I am currently having other problems on that site, clearing outlook.live.com cookies does not clear the problems.

Yesterday I updated Firefox to version 115.22.0esr this morning when it was released. Have never had any problems viewing video on Netflix but now I am getting Netflix error message F7702-1003. Yesterday I asked "what can I do? I've rebooted computer as Netflix says and it didn't help."

Today, to see if the issue was a bug with version 115.22.0 esr I logged onto both Peacock and Hoopla to try to stream video. On both sites the same thing happened that happened on Netflix. I log into the site, select a video, and when I try to play it I get a message that "widevineCdm plugin has crashed" and video won't play.

Since this problem just appeared after I updated to version 115.22.0 esr it seems likely that there is a bug in this version which is crashing the plugin and preventing streaming video. I note that I can stream some video having checked both YouTube and an online television station.

Hello all,

Ever since an update to Firefox from a few weeks ago, I have been having issues with white backgrounds displaying incorrectly in Firefox. I have attached two identical images from the NYT homepage: the first is a screenshot from Chrome and the second is the same exact image but taken from Firefox.

I have also attached another screenshot taken in Firefox from REI.com. You'll see that it's not necessarily just a white background that is causing the weird blue color. It also happens in products images being displayed incorrectly.

I figured this might be a Firefox website appearance setting, but I have played around with it and selected many different permutations and I haven't been able to solve this issue. I have also tried refreshing Firefox, using Firefox in Safemode, disabling all of my plugins/themes, etc. and nothing was fixed.

I am pretty sure this isn't a system wide issue or a monitor issue because these websites are being displayed 100% correct in Chrome and Edge. This is only an issue in Firefox.

Can someone advise?

Thanks,

DC

I cannot log into websites that use CloudFlare as their CDN. ChatGPT gave me a laundry list of things to check, and after exhausting that list, I decided that the great developers at Mozilla might be able to steer me in the right direction. Below is what ChatGPT suggested:

I asked:

> When trying to log into any resource that uses the CloudFlare CDN I get the following response: > > Icon for givewp.comgivewp.com > > Verify you are human by completing the action below. > givewp.com needs to review the security of your connection before proceeding. > Ray ID: 90067ba77ed70ff1 > Performance & security by Cloudflare > > After checking if I am human or not, the login proc fails with no error message and then just presents the captcha again. > > This only occurs when I attempt to login to resources that use the CloudFlare CDN. > > Is this a known issue with CloudFlare. If it is, is there a known solution to the issue?

ChatGPT replied:

> Experiencing a recurring CAPTCHA verification loop when attempting to access websites utilizing Cloudflare's security services is a known issue that can arise due to various factors.
