I am using Firefox Developer Edition Version: 110.0b5 (64-bit) on M1 Mac running Ventura 13.1.

I am building an webapp some XHR triggering in background but it is not necessary to run the application (running fine on other browsers). But on Firefox Developer Edition, It shows a error window with the message and stops loading the application.

Firefox can’t establish a connection to the server at localhost:4000.

localhost:4000 is the failing XHR request domain. I have attached the screenshot.

How to ignore the XHR failing errors just like other browsers?

For some reason Montserrat fonts ignore font-weight for me on all websites. In happens on my main browser profile, with a new clean one with no add-ons and even in Tor Browser. Pictures 1 and 2 illustrate the problem. If i go into page inspector and replace "font-family: 'Montserrat', sans-serif;" with "font-family: 'Segoe UI';" the parameter works as expected and the alternative font is rendered properly.

Reinstalling fonts from fontsource.org didn't help.

OS: Windows 10 1607, FF - 120.0, issue was present for many versions before.

Im opening hbomax site and everytime i just get 3 loading dots and sudden black screen, i tried clearing cookies and cache, i tried troubleshoot mode, its still the same. Site works fine on chrome

I am considering abandoning Google browser because of the Canadian News issue they are opposing. Where does Firefox stand on this? Is there something I should be wary of in making the switch from Google to Firefox?

Google Calendar has not worked right on Firefox (version 118.0.1 (64-bit)) on macOS since I updated to macOS 14.0. For example, when I try to use the "Search" function, I can't type a search string. Or sometimes when I create an event I have problems typing in the event title field as well. On these occasions when it doesn't work there is no blinking cursor placed at the left end of the text field, so you can't type in that field.

Hoping that this isn't just me, since I really like using FIrefox. Have had to move to the Edge Browser because Google Calendar is a central tool for me that has to work without having to fiddle around.

When I go to www.shoutfactory.com/shop and search for some movies, when I click on them, the page is blank (white). The tab looks like it is a gear icon. Yes I have tried Safe Mode and Yes ublock origin is disabled for the site in question. Page works fine is MS Edge Browser.

Regards, Sir/Madam The webpage is empty. [link] Although the page is currently blank, the website icon in the upper left corner suggests that contact has been made. Anyone know the reason why Firefox is unable to load the website?

When I try to log into Google I get this message:

This browser or app may not be secure. Try using a different browser.

I am using Firefox 91.13.0 ESR (64bit). I have been using the 91.x ESR releases for a while now and this is a new problem that I never had before.

On website libertynation.com images are not displayed in Firefox ... they are in Chrome ... what's up? Have not noticed this on other websites.

Vs 117.0, installed this morning, will not "continue to spotify", during the login process to the spotify desktop app. All had been working perfectly over the past few months until today. Was able to connect to spotify thru Chrome, but something get changed/broke in the new firefox v117.0 (64 bit), Win 10.

Since the last Firefox update (I'm now using Firefox 113.0.1 64bit on Windows 11) when I play a video on Twitter, it plays with the right colors until I fullscreen it. When I fullscreen it, the video becomes darker and the colors are wrong.

• The same happens to youtube videos (both fullscreen or normal size): the colors are not right and they looks darker.
• The same problem happens using both my laptop's internal monitor and the external monitor.
• I tried to reinstall Firefox but it didn't fix it.
• I also tried to take a screenshot of the "wrong colors" videos using the Windows screenshot tool but the output image is displayed with the right colors and not with the darker ones.
• Using Chrome the colors are correct and I never had this problem before the last Firefox update.

My website works perfectly in Edge and Chrome, but "View Cart" does not in FireFox. Additionally, I have the FB link so my customers can "like" my page; it does not display in FireFox. My MailChimp login repeatedly sends a verification code every time I log in with FireFox; not with Edge.

I have reviewed the recommendations for settings and nothing has worked. Using FireFox for years without all these issues. If I need to do so much to make FireFox work, I will have no alternative but to use Edge as my default browser.

Getting unreadable text when website is using a font that isn't installed (see attached screenshot). When I view the source in developer tools it uses Roboto (which I haven't installed).

On my Mac, I have tried other browsers (Chrome and Safari) and they work fine. I have also tried this website with Firefox on Windows and it also works fine.

This site, Costco Instacart, worked perfectly with Firefox as recently as April 15, 2023 but today fails (see attached image): https://sameday.costco.com/store/costco/storefront?zipcode=11021

Cloudflare believes it is protecting itself from online attacks when accessed by Firefox. The same site worked perfectly today, on the same computer, using Google Chrome.

Cloudflare is a major CDN and many important commercial sites, like Costco Instacart, have their content delivered by Cloudflare so this is a major issue with Firefox. For the moment there is a work-around, use Chrome instead, but it would be better to have Firefox address issues with Cloudflare.

For the past few days I get the request to enter captcha characters every time I try to access the Amazon website using Firefox on my Win10 PC. It works fine on my Firefox for android on my phone and also works fine using the Edge browser on this PC.

I've tried resetting Firefox. I've tried troubleshooting mode. I've tried turning off enhanced tracking. What else could cause Amazon.com to feel the need to verify that I am not a robot ?

I am unable to sign into Costco.com using Firefox. I get an error message:

    "Bad Request - Header Field Too Long
    HTTP Error 400. A request header field is too long."

Turning off all extensions didn't help. Opening a private browsing window DID work. Using Chrome DID work.

Thanks!

Dropdown lists are not displaying their contents when selected on certain websites, including eBay.

I have tried using Troubleshoot Mode and the dropdowns are still not displaying.

Here's an example where I am seeing this behaviour: https://www.ebay.co.uk/itm/255536264049?var=555488018135

When I select the Resistance Level dropdown, nothing happens. It's the same for any listing that has a dropdown.

This issue occurs in both RPM and Flatpak instances of Firefox.

I have tried the same page in Chromium browser on the same computer and the dropdown functions correctly in that browser.

I have also noted the same behaviour on other websites, such as train booking sites, but I don't have any other examples to share at the moment. It isn't an isolated eBay issue anyway.

Any ideas? Is anyone else experiencing this issue?

Since Firefox 109 and 110 also you can not login to hidive.com. It just loads a blank page(empty source) but not logged in. Firefox Developer Edition does work. 110 and 111. Tested on both linux and windows without extensions and tested with tracking prevention turned off. I reported this after 109, but I could not find the report.

Auction Site 'Catawiki' will not load signing in page. Yet if I use incognito mode I can sign in. I have cleared the cache and disabled my add-blocker but still no joy.
