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?

I have a user who runs SRS/Crystal Reports on their Windows 11 Lenovo laptop, but every time we go to the website where a Java-enabled pop-up window for viewing spreadsheets is supposed to load we keep getting a "A plugin is required to play this content" error message, but no option to install/approve the running of Javascript.

I have downloaded and installed the JRE and JDK on the endpoint device, but still no luck getting Firefox to load it. I am running the 32-bit version of the web browser, not 64-bit, so I am kind of stumped about how to proceed from here.

Is there a place I can manually download/install these Java plug-ins?

Thanks.

I have autofill turned off, but whenever I go to a a particular page that has a contact form for a web-based software I use for my business, FF automatically puts my first and last names in the respective fields, in the place of existing names for my particular contacts.

How does FF have my name in the first place, since I have never knowingly provided it, how do I remove it from FF, and how do I stop this autofill from happening, since I have it turned off yet it's still working?

I've been getting funny glyphs on my google engine searches. See png. Turning off add ons and reinstalling software doesn't seem to clear the issue.

The funny text when copied and pasted is revealed to be the actual text it was supposed to be.

This is very very weird... and its only on firefox, no issue for chrome or safari. Happened just a few days ago. Don't remember installing anything. Could be malfare from a font site?

Hi everyone.

Since updating to the latest version of Firefox, I can't see anything displayed on the Youtube website.

When I open a tab and navigate to Youtube, I can see faint grey placeolders in the background, but no images or text (screenshot attached).

Does anyone know why this is happening?

Thanks.

Using Mac OS 12.4 and Firefox 101.0.1. After launching Firefox, a second icon appears in the "recently used" apps section of the Mac OS dock (see attached screen shot). The icon stays there and goes away, and then comes back, and then goes away, etc. This continues on and on until Firefox is closed.

Why is this happening? Never acted this way before the latest updates.

I've noticed that when I download a PDF attachment or file firefox open the file on same tab instead of new tab.

How to I change settings to open pdf on new tab and not the same tab?

I watch videos on dropout.tv which uses the Vimeo SDK as their player for the videos. After switching to Firefox, the video progress has consistently started from where I left off on Chrome. The site doesn't remember where I ended the video when I watch it on Firefox. I assume this has to do with the cookies, but I've manually added "dropout.tv" to the list of exceptions in Firefox settings so that that site is always allowed to store cookies.

Returning briefly to Chrome, the player immediately tracked my progress again, so the issue is definitely related to Firefox somehow.

I've just downloaded the latest Firefox version and it won't load my Cornell email - adfs.ad.cornell.edu. I'm using a Macbook Pro. I can download the website on my iPhone.How do I get my email back?

When I start typing URL's in Firefox, it will only ever suggest the URL so far as the top level domain. For instance, I frequently visit trakt.tv/dashboard. But when I type "tr" into the URL bar, Firefox only ever suggests trakt.tv - I have to manually press the forward arrow key and type in "/d" in order for it to autofill the rest. It doesn't matter how many time I type the full URL in or even the fact that I've deleted all history only visited trakt.tv/dashboard, Firefox will still only autofill trakt.tv

Is there some about:config setting I can change to make Firefox recognize and prioritize specific frequently visited URL's over just top level domains?

Hi there! I can't clear my cache. I go to Preferences > Privacy & Security > Clear Data... but my recent URLs always still show up under History (see image). Please advise! Thanks

I cannot disable google document viewer in Google Drive. Every time I go to open a recently downloaded PDFs in Google Drive, it invokes Document Viewer unless I specifically right click and tell it to open with Acrobat. I have disabled everything thing I know in both Chrome and Firefox, cleared the caches, rebooted, and the default behavior persists. Worse, the Document Viewer REQUIRES a complicated, infuriating sign in process that has only worked ONCE in dozens of sign in attempts. Please help with this.

Clicking on the spacebar, does not produce a space between words, when typing text. I'm using a Mac Mini M1, on macOS Monterey (V 12.4), along with a Logitech MX Keys for Mac keyboard.

This happens randomly, for instance, on this very message. I previously posted a question regarding another problem that I came across with the same hardware and Firefox.

I found the solution to that problem by disabling an Extension in Firefox, however, I can't begin to think where to look for what setting, that may be causing my current problem.

I'm using a video as the background for my website, and Firefox's built-in PIP (Picture-in-Picture) icon for videos is displaying. I don't want it to be visible on my website. I tried using FFmpeg, but it did not work as it was mentioned by some people on Stack Overflow. I read that Firefox won't display this icon for videos in an iframe, but I don't want to use an iframe on my website. Is there any other solution?
