Firefox supportforum

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?

Just recently My patient portal at Baylor Scott and White was changed. When I log into the portal everything is fine until I try to see messages from Doctor. It at this time the crash begins, sometimes the screen goes black then White and black again repeating a few times, the the computer locks up and I have no mouse or keyboard and no error option or anything.. I have to power down computer to fix where everything is ok... The tech at Baylor Scott and White said its at my end because no one else has complained and suggested I use Chrome, which I did and it works, I can retrieve messages without crashes??

So, I'm a designer and UX Designer, and recently I installed Ubuntu and Firefox Developer. If you're a UX Designer you probably know about Figma.

The problem is that Figma uses the Alt key to show the distances between objects. But Firefox activates the Menu Bar every time I press it.

Can I remove the Firefox menu bar Alt shortcut?

_05: chrome browser network panel after refreshing 5 times domContentLoaded: 328ms

_06: firefox browser network panel after refreshing 5 times domContentLoaded: 1880ms (5.73x slower)

the problem seems from that the request from firefox gets 200 wheras chrome gets 304 unmodified, which explains the huge speed difference in reloading.

Hi!

I like to have my browsing history cleared after I quit Firefox, but I found out that this will break the action to open previous windows and tabs.

How to have these two options live together?

When I try to log in to any Google "Ecosystem" (i.e Gmail, Youtube etc.) I see it (check screenshot below). I'll use Firefox Developer Edition. In vanilla Firefox and other browsers, everything works as usual.

Hello, I am currently having an annoying issue when browsing Firefox on particular websites. There's this large, irremovable white bar at the bottom of the screen that appears when I'm browsing particular websites (it only appears on those and those websites only), but it never appears on other websites and there doesn't seem to be a way to remove it. I've tried clearing cookies and cache, disabling certain extensions but nothing has seemed to work so far. I'm currently using the Firefox Nightly, but the same exact issue is present on the same exact websites (developer.mozilla.org, codewars.com, etc.) on my regular version of the browser. This is getting really annoying and I don't want to switch to a Chromium-based browser, so is there any way to fix this annoying issue? Any help would be greatly appreciated.

When I have FF open, then close all windows but still have FF active, I hit CMD-T or CMD-N to bring up a new tab or window and nothing happens. I repeat, repeat, repeat and still nothing. THEN if I click on the FF icon in my dock, all the tabs and windows appear in a cascade of windows or tabs like bam, bam, bam.....

This happens on two MacBook Pros around 2016 vintage. This is a new behavior this week.

I used Speedtest by Ookla. When the broad band was installed, the technician did this without a problem. Today when I tried I was taken to an installation page. After I used the SpeedTest, then my main page was gone and instead I have a bar of Firefox selected options. I've tried to find how this is done so I can set it back but I can't find it. Please help.

Had to refresh Firefox but lost my bookmark sidebar & can't find a way to re-establish it. Used to be a setting for it at the top of the home page but none now. Can't find it in settings.

Using Firefox Developers edition since the update to 109.0b3 (64-bit). The scroll wheel doesn't work, the mouse button I have mapped to the back button no longer works. If I launch Firefox in troubleshooting mode everything goes back to normal and the mouse performs perfectly in troubleshooting mode. Back in normal mode I have tried disabling all three of my extensions and the problem persists. Mouse performs perfectly in every other application. Sounds like a bug, but I can't find anyway to report it. Any ideas? Thanks

I just had a glitch with the latest update to 102b, FF insisted I had an old version and would only let me make a new profile. So I had to set up multi-account containers again. I have specific sites opening up in each container, and I'd like to make a copy to make sure that if my profile gets goofed up somehow, I can always easily restore my setup with multiaccount containers just the way I like it.

What do I need to copy, so that with a new profile, all I need to do is copy over some files?

In my profile folder, I see an Extensions folder, as well as an extensions.json and extensions-settings.json.

Are those the only folders/files I'd need to restore multi-account containers on a new profile?

I have thought of using FF Sync, but I keep reading that it is not intended for copying, so much as sharing across different devices, which is not something I'm interested in. Should I just let sync copy my extensions, and then sign back in, in the event I want to restore addons to a new profile?

no sound from web ASDR radio stations since firefox update!

such as: http://k3fef.com:8901/ http://websdr1.sdrutah.org:8901/index1a.html?tune=1160am http://grimsbysdr.ddns.net:8073/

etc....

This one is ok!

Used to be very practical with add-ons in the toolbar (cf 1st screen), but with the update they are not here anymore (cf 2nd screen). I don't want to click on the extension button for those addons I'm always using, I want to revert to having the buttons in my toolbar !!!!!!!!

PLEASE DO NOT COMMENT TO GO TO CUSTOMIZE TOOLBAR WITHOUT TESTING IT YOUSELF AND INCLUDING A SCREENSHOT !! This does not work, there are no buttons to drag and drop for the addons.

Bought a new windows 11 ASUS laptop. Trying to install an HTML bookmark file from older windows 10 ASUS laptop. When I execute the HTML file import on my new ASUS windows 11 laptop, nothing happens. Even found and removed the "block protection" in the HTML file.

Why am I unable to import a firefox bookmark HTML file?

Thanks for any solutions anyone can provide.

Several times now when I access my banking site and export data, the exported data is not correct. Sometimes columns are missing or columns are in the wrong order. One time even the display showed missing columns. Another example is when I look up a stock quote, sometimes the numbers from previous days are displayed. Troubleshooting with the site manager we found if I cleared cache and cookies, the problem went away. Everything works for several days, then the problem reappears.

Clearing the cookies is simple enough but then I have to be re-verified on all of the sites that require such and that becomes a real pain. (ie. We are sending you a text, please enter the number to continue)

Google Chrome and Microsoft Edge both work fine with this site. Please don't make me switch but I will if this continues.

What about:config option do I have to disable to remove those new buttons from the address bar?

Firefox 105.0b2

I suppose the other question is why did you add them? There are already three places I can get at that information.

I saw many tutorials on making self-signed certificates get a lock sign of trusted certificate, which were installing the root certificate of authority in firefox which i did, and also installed in windows, i am using latest version of firefox developer edition, this is error i recieve:

Websites prove their identity via certificates. Firefox Developer Edition does not trust this site because it uses a certificate that is not valid for 192.168.0.102. The certificate is only valid for the following names: localhost, 192.168.0.102, 172.20.10.3
