Firefox Support Forum

I think this went missing in a recent update. Chrome seems to have hijacked it. I reset the email app in windows settings and mailto showed back up in ff, but it no longer shows gmail as the action.

Sometimes when loading a page, and the page is slow to respond, what is expected is seeing a notice of error, allowing me to refresh the page. However, sometimes the strange behaviours happen:

• The refresh button is gray. I cannot refresh. I can only to re-type in my URL bar to force reload the page; or
• The URL bar keeps blank or remains the former page. For example, I click the link on page A to page B, and page B is too slow, then I found that the URL keeps the URL of page A. I have to re-click the link of page B on page A; if I opens page B on a new page, then the URL keeps blank finally, and I have to re-click the link of page B as well.

The operation system is Windows 11. It also happens on Windows 10. It happens on Firefox and Firefox Developer Edition. The issue does not exist in Edge browers (in Edge, it displays connection failure and allows me to refresh).

The issue has been existing for years.

Hi...

Is there a way to edit bookmarks sidebar right-click menu. I want to change position of "Delete folder" and "Delete bookmark" to bottom of right-click menu.

Thank you

The issue I am experiencing is this - whenever I refresh a tab within my browser while developer tools is open on that tab, the DOM tree disappears completely. I am still able to click "inspect" and hover over elements, and I still get the visual feedback of the styles being applied to that element. Additionally, the CSS styles still display in the right-hand side of developer tools when I inspect an element. The only issue I'm seeing within the "Inspector" tab within developer tools is the missing DOM tree.

The other tabs within developer tools (Console, Debugger, Network, Performance, etc...) seem to be working fine (as far as I can tell). Navigating to another page within this tab does not solve the issue.

If I open a new tab within the same browser window, I am able to see the DOM tree again, but only until the page refreshes in which case the error occurs again. I have experienced this issue intermittently for a couple of years now, but this is the first time where it has been persistent despite re-installing browser, restarting computer, etc...

Please let me know if there is any further information that I can provide that might help solve this issue.

Thanks very much for any help that anybody can provide.

For example: I visit https://raw.githubusercontent.com/vvb2060/Magisk/b03fdcb14dc0e7ec88e98ac3dd769d96ab01c1e2/app/src/main/res/raw/changelog.md It open normally and I can directly see what inside of it. The "content-type" of this http request is "text/plain".

But if I visit https://cdn.jsdelivr.net/gh/vvb2060/Magisk@b03fdcb14dc0e7ec88e98ac3dd769d96ab01c1e2/app/src/main/res/raw/changelog.md Firefox will download it automatically, instead of directly open it in browser. The "content-type" of this http request is "text/markdown".

This is not the problem of "What should Firefox do with other files?" setting...

I make a test, I create a file "test.md" in the Nginx website folder, and I add "default_type text/markdown" to conf to force its content-type, pic here: https://vip2.loli.io/2022/05/12/v39nT8wu6yIlXeH.png

When I open it in Edge Chromium, it will shows what inside of it: https://vip1.loli.io/2022/05/12/EGFwgHPtNjqshyl.png

But Firefox... https://vip1.loli.io/2022/05/12/vuz8YBQAlD2ZCGk.png ( Here I turn on "Ask whether to open or save files")

I am using Firefox Dev 101.0b5 and also test it with Firefox Stable 100.0, the same.

Hello,

It got really hard to debug with Firefox Developer Edition devtools when inspector tab keeps disappearing while debugger point is hit.

Using HTMLElement link from console doesn't return Inspector

Pressing F12 and F12 again helps, but then again have to reach the break point which is frustrating.

Firefox 101.0b5 (64-bit) Windows 10 Pro 21H2 Build 19044.1645 CPU - i5-1145g7 RAM - 16gb

Any way to solve this apart reinstalling Firefox ? As well why the same bug can stay 8 years? https://support.mozilla.org/en-US/questions/980988

duplicate of /questions/1376840 thread.

found a bug with firefox 101.0b5 website https://www.express.co.uk/ it does not display the comments for an article. Works with Microsoft Edge

I searched extensively for this and could only find answers regarding bookmarks, not add-on icons. Of course I could still be missing it...

I am upgrading from Firefox Developer 86 to 101.

The spacing between add-on icons has been increased in Firefox 101, making the URL bar shorter:

https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-05-26-17-03-36-e06f37.png

Does anyone know of a userChrome.css script that I can use to decrease the add-on icon spacing in Firefox 101, to make it more like Firefox 86?

Hi, Firefox Accounts (Fxa) support TOPT (Google authenticator etc) 2FA, which is pretty good, however it would be great if you could support Webauthn/FIDO2 (Yubikey etc).

There was a Bugzilla bug for this, https://bugzilla.mozilla.org/show_bug.cgi?id=1464888 opened 4 years ago, however about a year ago it was closed wontfix because it "is not currently on our roadmap"

Which seems like a really bad idea? Given that most security people, browsers and OSs are saying "passwordless is the future", and FIDO2 is how that will happen. And even passwordless aside, FIDO2 is a more robust and generally easier to use option than even TOTP apps

I have a php file with an html video tag which recently stopped working in Firefox Developer Edition (FDE). It still works in other browsers. In FDE, the volume is permanently muted. I can't find a way to turn mute off. In About:Config under Media: there are messages at

media.decoder-doctor.new-issue-endpoint = https://webcompat.com/issues/new

and

media.decoder-doctor.notifications-allowed = MediaWMFNeeded,MediaWidevineNoWMF,MediaCannotInitializePulseAudio,MediaCannotPlayNoDecoders,MediaUnsupportedLibavcodec,MediaPlatformDecoderNotFound

The partial source code is:

just about everytime there's and update it corrupt my handler.json > handlers.json.corrupt. It's getting real annoying. I don't know why the whole mailto broke around version 99, but it did and I keep having to copy over an old handlers file each time this happens.

When I try and go back on YouTube, for example, FireFox would refresh the page I am on and if I hit it again it would send me too far back sometimes off the website entirely. What I find strange about this is that this only happens on my desktop PC but not on my Laptop. Both are running the same build of FireFox so I am thinking that there must be something in the settings of one that is causing this. It could also be the way I navigate webpages. On my PC I use a side button on my mouse. However, on my laptop I use the gestures on the trackpad.

If anyone has encountered this issue and know a fix please let me know

I just migrated from Mojave to Monterey on new MBP14 using TM. the old profile opened but Preferences/Settings will not open to a tab. The only way to open is to go about:preferences then it will open

It opened to old profile and that was fine but now I can't get Preferences to open and I don't want to lose all the extensions and setup I have done over the years.

Firefox returns what I think that the window object when I write document in the Firefox console to get the source code. I was trying to get the HTML in the console like Chrome. I'm learning to program and don't know where else to ask. I'm going to let you some pictures, maybe you can understand better. the picture is the return when I write document in the firefox console. sorry, I can't explain better but I'm late to work.

I had set up a userContent.css file in the past to pull up and fetch an image on my computer to display as a background on the homepage. It worked and did it's job until recently, when I had recently relocated a lot of my files around on my computer. I have redirected everything to where I want it to look, including the userContent.css file to the new location for the image I want as the background. Firefox loads the .css file correctly, and recognizes the file existing, but it won't load the image itself for some odd reason. It states it "may not load or link the file" because of a security error, and thus, can't load the image. I never had to deal with this before. How can I get Firefox to be able to load my image like I want it to? I have screenshots that I can provide, but this site doesn't want to upload them at the moment.

Hi everyone,

I am having trouble getting my custom new tab page to be focused when opened (instead of the address bar).

I am currently using the `autoconfig.js` + `mozilla.cfg` approach to overriding the `AboutNewTab.jsm` service with a custom local file. This is working great with the two files containing this code:

autoconfig.js: ``` pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0); ```

mozilla.cfg: ``` // Custom firefox config

let { classes:Cc, interfaces:Ci, utils:Cu } = Components;

try {

 Cu.import("resource:///modules/AboutNewTab.jsm");
 let newTabURL = "file:///home/vallode/Documents/test/index.html";
 AboutNewTab.newTabURL = newTabURL;

} catch(e) { Cu.reportError(e); } ```

I have been attempting to use the `gBrowser` global to add an event listener to the new tab opening, but with no success. Could anyone point me in the right direction for something like this?
