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?

Crash report submitted bp-37f84164-6125-4ae1-9e55-8a8200230225. Started happening about once a day over last few days possibly since 110 FF update (Ub kernel was also updated a few days back) Have to do a hard power off & restart

my scroll wheel stopped working on firefox, so i launched in safe mode and my scroll wheel was perfectly fine so i disabled all of my addons but it still doesn't work

I normally have my bookmarks showing to the left of the main window. I have many, in various header categories like medical, games, finance, etc. Recently I was doing some and wanted to close the bookmarks to give me more room for the main page. I THINK I did it very easily with a right click and close folder or some such thing. Worked great. I got to have more of my display to show on the page.

I am now incredibly frustrated that I can't get them back. I have done research and tried to follow the directions but can't get it to work. I have found Bookmark Tools and Options and I have "always show" checked. But I can't get my bookmarks back to the left of the main page where I can easily go to where I want to go.

I need help! Please. Very frustrating.

Hello. First of all, does anyone know where a list of supported query terms for smart bookmarks could be found?

I already know some, such as "sort=" and "maxResults=", but would like to see a full list.

Second, would it be possible to use smart bookmarks to show a list of visited websites whose URLs match a pattern such as "food.com/*doughnuts*"? That is, all websites from food.com that also have the term doughnuts in the URL?

It only happens in Firefox. I can't open any website on Firefox , even google.com . However, the following link is what opens instead : "http://www1.cdnsure.com/?tm=1&subid4=1677529420.0141530000&KW1=Google%20Cloud%20CDN&KW2=CDN%20Solutions&KW3=CDN%20Video%20Provider&searchbox=0&domainname=0&backfill=0"

idk what's that "www1.cdnsure.com" website .

Hello, I have two questions about private windows.

First, on the Home tab it says: "Firefox clears your search and browsing history when you close all private windows"

but what happens if Firefox crashes during a private window session? Will some remnants of your activity remain in some files, as Firefox did not have the chance to clear data as it normally would when closed gracefully?

Second question, when in private mode, does Firefox write data to either favicons.sqlite or places.sqlite (even if only temporarily)?

Thanks.

Outlook.com email service has stopped responding to clicks on "Inbox". First attempt opens the Inbox, all other clicks to go back to the "Inbox" do not work. The only way to go back to the "Inbox" is to use the back arrow in the browser, or click on "Sent"(or another file)...then click on "Inbox". The cycle continues. Been like this since I updated to 110.0.1 (64bit)

When I do the keybind (Control + P) or press the print icon in google apps (google docs, drawings, etc) it automatically downloads a pdf instead of opening the print menu. Chosen solution

Printing on any other site pops up with the printing options. Only on google apps does this happen, including gmail.

This problem is non-existent on Google Chrome and Edge. It does persist on Brave although. Haven't tested any other browsers.

Yesterday, my scrollwheel stopped working on my mouse in Firefox. The mouse moves the cursor fine everywhere, including Firefox, but the scrollwheel only works in other browsers/programs.

Like the title states - now have to scroll back down through all the bookmarks in a folder because it no longer holds its place. This is a great time waster.

Thought I would try to save some time by opening bookmarks in new tabs, but it then switches to the new tab immediately and I still have to scroll back through the same folder to open the next bookmark.

Is there a fix for this issue?

Two updates ago, I had an issue where if I used any Google web products, I had weird network problems that just didn't go away (4000ms ping spikes every 5 packets). I noticed it was only when I was using Firefox, so i tried disabling add-ons and extensions, it still happened. I opened it in safe mode, it still happened. I tried using Chrome and Edge, both did not cause issues.

I reset my Firefox completely (There was some custom CSS to put tabs on bottom, where they belong) and it was perfectly fine! No issues! Everything was great for a few days!

Then you guys updated things again... and it was back... so I reset my Firefox again, and even straight out of the box, its still causing the issue, but now only when using google products, with or without add-ons, there is no custom CSS anymore either.

I do not know why its an issue, but it is, and it is ONLY with Firefox, and I really do not want to switch to Chrome or Edge... It also persists after Google is closed, until I restart Firefox.

I am unsure of specifically why this is happening now, but it is a MAJOR problem for me

The Mozilla article says to go into about Firefox where you will be able to view which version of Firefox you are using. How do I know if this version is the latest version?

The article says that the best way to update Firefox is to do it from Play store. It says to tap on the my apps link to see which apps need to be updated but there is no my apps Link in Play store.

How do I determine if I'm using the latest version of Firefox on android?

Hi there! I'm kind of clueless with this problem of mine. Is there any way to set a homepage on android firefox, where I hit the home button on the left top corner and it is just going to take me to eg. google.ie? Same like on the dektop one? Also when i hit a link the mobile browser just keeps opening a new tab anytime I click on one of them? Hope it is understandable, english isn't my first language. thanks in advance for any help.

bold text I need to save all of my bookmarks and history so I can add them back in after wiping and reinstalling Windows 10 and then reinstalling Firefox on my computer. How do I do that?
