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.

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.

How to prevent that Firefox auto start download files with Header "content-type: text/markdown"?

For example: I visit https://raw.githubusercontent.com/vvb2060/Magisk/b03fdcb14dc0e7ec88e98ac3dd769d96ab01c1e2/app/src/main/res/raw/changelog.md It open normally and I c… (閱讀更多)

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

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

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

MacOS FF dev edition 102: I have a folder in my bookmarks toolbar, and I frequently open all of them in tabs. But that option is missing from the context menu on the folder. It is there at the bottom of the folder if I click to open the folder, but this is silly. There is an "open all bookmarks" context menu option on the folder, but that opens all the bookmarks in the toolbar, not in that one folder. why is this?

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?
