Firefox Support Forum

Firefox is my longstanding browser (on Windows 10). I wish to make use of the Firefox PDF viewer, but have been unable to gain access to it. If for the purposes of an attachment I click on "Open with", Firefox does not appear among the viewers offered. I'm not tech savvy, so a step by step (idiot's) guide as how I can gain access to and then make use of the Firefox as my default PDF viewer will be greatly appreciated, please.

Getting to www.costco.ca impossible during past few days - disabling tracking does nothing! Tried relaxing most security and tracking settings, still no results. MS Edge works just fine, like Firefox used to until now. Guess it's time to switch if no other option.

Just recently been getting yahoo search engine results to open in new tabs rather than the same tab. I have searched for other users that have the same problem and have done the tracking protection thing and deleted cookies, but nothing helped. Also tried Troubleshooting Mode and it still persists. Any other ideas that may help? I'd appreciate it.

Hello,

I have been working with OpenTable support for 2 months. We finally resolved it is not on their end.

Issue: When opening opentable.com the website loads and then a blank page is presented at the end. You can see a flash of the base site and any links that were attempted.

Items attempted to resolve:

• clear cache and history
• updated firefox site
• downloaded, uninstalled and reinstalled firefox
• incognito mode
• removed all all ons/plug ins
• tried links to pages outside of opentable.com

I have their responses and what they have attempted (in emails should you want). I also have snapshots of what I see. The odd thing is completely removing firefox and installing should have fixed it but it didn't.

One thing that does work is links to opentable from restaurants (email or from their websites). Initiating from the base browser does not work.

I am on Windows 10 and all updates have been installed.

I've written about this before and never got a working answer. I have to use Chrome or internet explorer for some work because FireFox won't open the sites. This problem hasn't been fixed by I clearing cache and cookies as recommended back when I first asked a year or so ago.

Now the latest website I haven't been able to use is the Post office! USPS.com -- If I try to track a mail piece using my tracking number the site can't bring it up. The site tries for long time then tells me to try later. When I try with another browser such as Chrome, the result is there within a couple of seconds. It looks like I'm going to have to leave FireFox which I hate as I've used it so long - over ten years at least.

WebGL still not present in Firefox with 21H2 Windows LTSC my previous question was closed and still no solution. Nothing advised helps the issue. On the same system it works in Nightly!!!!

Every time I enter a new password at https://secure.newegg.com/identity/signin, I click on Save but the browser does not save it! When I try to log in, Firefox always inserts the previous password that was saved. I have Reset the password twice on the website and have mentioned it to Newegg at least twice now and so far, I have not been able to resolve this problem.

This only occurs with the Newegg website. Why is this?

This is occurring on a computer running Windows 10 Pro version 22H2, Build 19045.3693

I request that this be resolved soon.

Thanks,

Wayne Carpenter

Later version refuses to connect to my modem, and goes into security web mode. This modem uses HTTP/HTTPS for access, i.e., connects directly it's IP address, then the user enters a username and password. At that point, the the modem switches to HTTPS for control.

With this recent update, there is NO WAY to access the modem for any work, or upgrade the HTTPS certificate on the modem. This is a BUG.

What should happen is that if the web site will accept a HTTP connection, Firefox should NOT refuse connection or test for security issues UNTIL the user or the device switches to HTTPS.

As an aside, I've used Firefox on this Zywall modem for years until recently.

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

Hi,

I cannot logon to icloud using Firefox (since 3 days) on my windows pc. It normally works fine

I can logon on using the mobile firefox browser and I can logon using Edge. However, I don't want to use Edge

I use a VPN (including browser extension) but I haven't had a problem before

Thanks

Our office uses a cloud-based database. Mozilla won't allow me to "check" boxes to do database searches for specific things. Google works fine, Edge works fine, but not Mozilla. Any ideas on how to fix this would be appreciated. Thanks!

Firefox is blocking/preventing me from visiting a website even though it is secure but Firefox does not recognize the certificate issuer. How do I get around this? Thank you.

I've had this problem for a while and it's kept me from actually using the program. At any given time when I try to run the application, it never lasts for more than a couple seconds before it suddenly stops with no warning. Whenever I get these crashes, the Crash Reporter never opens. Because of this issue I can't open it in troubleshooting mode. At this point I have tried fully resetting my PC twice, uninstalling McAfee, had multiple malware scans, and have uninstalled and reinstalled Firefox itself multiple times. I'm really not all that good at operating computers, I just kind of know how to navigate files. I don't know what else to do at this point.

Hello Mozilla Support,

Since 2 upgrades ago, anytime I try to watch a livestream, my browser slows right down and then crashes.

I don't care why its happening, I just want a definitive fix for the issue.

I'm so aggrieved at this happening constantly, if you cannot provide a firm resolution to this issue, i will simply move to another browser.

I've tried your about:config setting restart to false and other fixes but still keeps happening.

I await your reply.

With Regards,

Mark

Facing a strange problem in firefox. I have saved user name, password for my site in firefox, when i have login again firefox is asking to fill from the saved one. If i choose that, user name alone filling leaving the password field empty (please refer the attached image) and also password field is in disabled state and not allowed to edit the password field.

And this is not happening regularly. Any idea how to solve this or is there any config for such behavior.

The full website link has /users/login, but when I checked the saved passwords, the link stops before the first /, its just websitename.com, instead of wesbsitename.com/users/login, and I suspect the full link not being save is whats causing it not to show up. Is there any way to brute force it to show up?
