Firefox Support Forum

Hello. We are using Firefox on our work computers and seeing issues with font rendering. Some sites have fonts that don't render well and are indistinguishable from the background. We are seeing this issue in Firefox on more than one computer, more than one operating system, and more than one website.

For all machines that we have tested, switching to Edge allows us to see the fonts and they seem to render properly. I'm not sure what is going on but some of these sites are important to our daily work and we have to use them.

Thank you for your help!

Recently I have been getting an error where after some point in time youtube-related pages will stop loading when I try to open them or if they do load they will tell me I am not connected to the internet despite being connected to the internet. It will have occasional brief windows where it will load the site again before going back to not working but I have no idea what causes this change. I have tried clearing my cache/cookies and disabling my add-ons but neither of those things stop this from happening. Interestingly, if I restart in troubleshoot mode or open a private window, youtube will load perfectly. Any suggestions on what I can do to fix this issue?

I am having one problem with Firefox. Other than this, it is working splendidly. Thank you. I work with an online donation management software application called: eTapestry. I am on it all day, for 17 years, it's my job. The login page does not fully load. This started yesterday, Monday, July 11th. I was able to find a work around yesterday, but this work around doesn't work today. The completely loaded page should look like the enclosed image: Sign-In-1.png with the blue 'Sign In' button being the active link to sign into the program. However, what I get is shown in image: Sign-In-2.png where there is a revolving circle of dots. Normally the revolving circle of dots would be just a blip of a second before the blue 'Sign In' button appeared. What do I do? Is this a result of the 102.0.1 upgrade? Thank you.

I cannot seem to reach https://community.esri.com/ via Firefox but can reach it fine with Chrome and Edge.

Firefox says "The page isn’t redirecting properly. An error occurred during a connection to community.esri.com. This problem can sometimes be caused by disabling or refusing to accept cookies."

So I even added the page to list of Exceptions, but still cannot reach site.

I've been trying to do some research on this and I've tested a number of results (clearing cache/cookies, running on Safe/Troubleshoot mode) but I'm still getting this error. I have also done a complete reinstall of the Firefox browser

I don't have any issue logging into any of the Google applications (gmail, youtube, drive, etc) on Chrome or Edge on my Windows machine, and I don't have any issues on my Mac running firefox, this issue seems to be specific to my Windows 10 OS on firefox.

It also occasionally works, so it's really confusing trying to debug what's going on (it works randomly if I refresh enough.

I'm not sure if it's related, but Youtube occasionally has issues connecting as well with the following issue. Any help would be greatly appreciated, I would really prefer this to work properly, otherwise I might end up having to switch browsers since it greatly effects a lot of things.

Cannot open PDF from MS365/Sharepoint site. Error message: "ERROR: URL provided is expired or invalid. Please reinitiate the workflow..." Checked:

1. 1 Other file types open/download correctly.
2. 2 Other browsers open PDFs correctly.

The issue seems restricted to Firefox and PDFs.

When I am on USCIS.gov, if I click some links, I get "502 Bad Gateway" error. I then have to switch to use Chrome. I've had issues with Firefox also when trying to get help at quickbooks. I have to switch to Chrome for that as well. It's a nuisance. How do I fix it? I'd rather use Firefox but I have less problems with Chrome. However all my bookmarks and browser bar links are on Firefox which is why I would rather stay with Firefox.

The New York Times is only partially loading with white space on the bottom. The same with article links. The ad blocker is off. I deleted the cookies. This just started happening a few days ago. Can go back from article to home page either. Other sites are working. NY Times works on Chrome.

I'm using Firefox 102 on Ubuntu Mate 20.04 (the vanilla one from apt), but I think I've experienced the same with a couple of previous versions too ...

So, I've sat in one Espresso House in Denmark; tried to connect to their public Wi-Fi with Firefox in private mode, captive portal went fine, and I was on the Internet. Apparently I had gotten a danish IP address there, since google.com thereafter was in danish.

Now, I sit in a different Espresso House, also in Denmark; however, here, captive portal does not work; in the sense that:

As shown on first screenshot, first I get "You must log in to this network before you can access the Internet.", and I get a "Open network login page" button.

I click on the "Open network login page" button, I can see browser wants to load http://detectportal.firefox.com/canonical.html - but in the end, I do not get the Espresso House login page, but instead I get a redirect to https://support.mozilla.org/en-US/kb/captive-portal , where the "You must log in to this network before you can access the Internet." still stands, but there is no more "Open network login page" button (as shown on the second screenshot)

If I restart the browser in this shop, I think I get the exactly same process - Espresso House wi-fi login page never gets shown, only the https://support.mozilla.org/en-US/kb/captive-portal ...

Strangely, at this point, I do get access to the internet through a browser - but google.com is then in swedish, which I guess means, that there is some sort of a VPN of that shop's wi-fi to Sweden. On the other hand, I don't get internet elsewhere on my computer - for instance, if I want to do `sudo apt update` from the command line, I get errors like "Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)" - which is what I otherwise get in (the first mentioned) Espresso House, before I've connected to wi-fi via captive portal (once I connect to wi-fi via captive portal there, `sudo apt update` or any other network access from command line is fine).

(Note: my android phone in the same shop, does indeed show Espresso House Wi-Fi login prompt upon Wi-Fi connection, and I can login there fine).

Why does this happen, and how can I force Firefox to show me the actual captive portal so I can login to Wi-Fi - instead of redirecting me to https://support.mozilla.org/en-US/kb/captive-portal ?

Hi all, I'm having a lot of problems with Firefox crashing pretty often. Sometimes once or twice a day.

I most often see crashes in the middle of a Webex video conference for work. But Firefox sometimes goes down in other situations that I see no pattern in.

This is Ubuntu 20.04, Firefox 102.0. Unfortunately, it's a complex environment to debug.

First, when firefox goes down, it rarely leaves a crash report behind. So I'm not getting any direct evidence as to what is happening. Second, I run with uBlock active and it is very difficult to function in the browser without long enough for the crash to happen. Third, I typically have several hundred tabs open. I have a lot of memory (64G) in my machine, and the machine doesn't act like it's swapping, so I don't think I'm running out of memory.

Any help getting to the bottom of what's going on is welcome.

I have some websites in the internal network with self signed certificate which I have registered in the exceptions. But every time I visit them he asks me to put them back in the exceptions. Is there a way to fix this problem?

I have found that my Fiefox cannot handle live news streaming and video playback and the picture freezes but the sound continues. This has been going on for years but I do not have a problem with any other browser.

I use tabs within windows to keep track of to-do items/wish lists etc. I had about 5 windows open with anywhere from 10-30 tabs each, my firefox closed unexpectedly and did not give me the option to recover the windows and tabs as it has before. Any way I can recover these or am I screwed? Thanks.

Hello,

I get Secure Connection Failed - SSL_ERROR_HANDSHAKE_UNEXPECTED_ALERT error code randomly while trying to open youtube.com. It works with other browser. Please help to solve this problem.

Hello,

The issue is as follows: unless I use 'alerts.useSystemBackend = true' (which I don't want to do), I'm not getting any push notifications.

Using this test site: https://www.bennish.net/web-notifications.html - the logs goes as follows: Notification #1 queued for display Notification #1 closed

What I've tried: troubleshooting mode, reinstalling firefox, using a completely fresh&clean installation, and even reinstalling windows. Even after reinstalling windows and immediately installing firefox, the problem persists. However, it doesn't happen on another machine I've tested on, everything works perfectly there.

What could possibly be the problem? Please help!

There are two websites (at least) in which I've been receiving the same error message (see attached). Because these were sites I need for work, I first worked with IT Services and they first suggested clearing the cache. That did seem to work for about a week and a half. However, 2 days ago, it started happening again and now clearing the cache does not seem to work. I know it's a firefox issue because the pages load fine on Chrome.
