Diễn đàn hỗ trợ Firefox

Hi there. I'm a blind web developer and I was wondering if there is some way to make the Firefox developer console more screen reader friendly. As it stands, I have no way of viewing JavaScript runtime errors or much of anything besides the element hierarchy when inspecting an element, and even this only provides very little information. I ask because there seems to be a big focus lately on testing for accessibility, but the tools to do so seem completely inaccessible themselves.

I would welcome any suggestions on how to use/improve the dev tools with a screen reader (I'm using NVDA) or an add-on I can down load that would be more friendly to me. I saw a mention of one called "Firebug", but that appears to be an outdated post.

I would like to clear/delete ALL UNPINNED top sites thumbnails at once. Similar question was posted over three years ago... no solution was ever given. Having to go through them one at at time, clicking Delete from History, confirming, over and over and over, is a real pain. If the info is stored in a sql database table or even a json, it would at least be a quicker way! AND some of the thumbnails require multiple click to finally get rid of! Can you help?

Hi, How can I get rid out of this "pop-up" from Google (attach) which is now always popping over my browsing search, without open one Google's account ? Cookies block on Firefox 80.0.1 does nothing on this issue ... What to do ? KR Thanks !

Links from other programs and Windows Explorer "Open With Firefox" won't open in Firefox! What settings do I have to change to get Firefox to work properly? I am using Firefox 80.0.1 on Windows 10 Pro Version 2004 Build 19041.450

Any comment will be appreciated Pierre

Hi guys, I'm changing from Chrome to Firefox Developer Edition, and I need to change the style of developer tools, background color, highlight color, font size, and line-height...

I want to modify the theme like the Material Theme in Google Chrome.

Thanks in advance!

So, I want to run Firefox from the command line withoug address bar and in a new window. I found that I can enable ssb and try it with: firefox -ssb http://127.0.0.1:6680/ This doesn't work, so I tried: firefox -ssb -url http://127.0.0.1:6680/ This opens it, not in a new window but in a new tab of an already existing session, and the ssb argument doesn't seem to work. Then, I tried: firefox -new-window http://127.0.0.1:6680/ This does work but again, there's still the address bar. The -ssb argument works with websites like google.com etc. but not local sites like the address I mentioned there. What do I do?

When I use the Firefox v80.0.1 browser and enter a file: URL (i.e. "file:///X:/Path" ), the folder icons are missing from the sub-folders (subdirectories). All other icons appear to be present. The folder icons were present in past releases, so it appears to be this release. Is anyone else experiencing this?

Hi, i absolutely do-not-like & do-not-approve that Mozilla Dev Network MDN https://developer.mozilla.org/en-US/ is FORCING/COERCING us/users TO GAIN (READ+WRITE OR ANY-OTHER) ACCESS INTO MY/USER'S GITHUB OR GOOGLE ACCOUNT to login into MOZILLA MDN site. This is clear Anti-privacy & Anti-Security activity, VIOLATION of PRIVACY-RIGHTS.

Any users can create an account in Mozilla here: https://www.mozilla.org/en-US/firefox/accounts/

So WHY MDN does not allow to use that to login/access into MDN site ?! and instead FORCING users to use GitHub/Google account access based login ?

Why should i give "MOZILLA", a 3rd-party, VARIOUS-TYPES-OF-ACCESS into my Google/GitHub account ? !! !! !! !! just to view documents from Mozilla developer network site, Or to get Firefox Dev Tools, etc, etc !!

my accounts are used for my control over my projects & to have my control over my private data/emails. even a tiny moment of access into any such private account means PRIVACY is LOST, & NOT-PRIVATE anymore.

Mozilla can send a code into my email & i/user can post that code to Mozilla, to prove i'm/user-is the owner of the email-adrs ... and for entire world , this type of proof is sufficient (though not perfect).

So WHY MOZILLA IS NOT FIXING THIS/THESE ISSUES ?

If Mozilla need to send notification to me, it can use my email-address. if Mozilla needs to add/notify in GitHub in my projects, then it can use its own GitHub account to do so with specific direct MENTION to user(by using user's github-ID) , or it can send me/user specific code over email that i or a user can add myself/themselves. A user can also give Mozilla-bot a membership in their Github project to publish, or notify something. etc. etc. there is always alternative & PRIVACY-RESPECTING & better-security-practice solutions , w/o giving/having FULL-or-PARTIAL access into someone's GitHub/Google account.

My browser shows a triangle in the top right corner of the screen. A click there states "Reconnect to Firefox Account". On attempting this action, after entering my password, I am asked to enter a 6 digit number sent to my email address. Unfortunately this takes more that 30 minutes to arrive at this far corner of the Earth but it states that it expires in 5 minutes. On entering the received 6 digit number, I get a message that it has expired and my attempt at reconnecting is terminated. I have tried this exercise 2 or 3 times, days apart but to no avail. Where do I go from here ?

Hello,

How can choose a default profile forever ?

I'd like to set a profile as the default one but whenever I open another profile, Firefox sets it as the new default profile so when I open a link, it opens it in the new one instead of the default profile I've set.

I've tried to set the profile.ini file as read-only but Firefox crashes when opening a new instance.

Thank you.

Hi, I really need help. I can't understand why Firefox kills properly registered push-subscription!? In my app, I properly register a service Worker, get permission, and subscribe to push notifications. Then I save the subscription in my database and send PUSH notifications. Everything works well, in different browsers (Opera, Chrome, Firefox). But after a while when I send another push notification to Firefox I get a response:

"code": 410, "errno": 106, "error": "", "more_info": "http://autopush.readthedocs.io/en/latest/http.html#error-codes", "message": "Request did not validate No such subscription"

If re-subscribe, it starts working again for a while... This problem is ONLY with Mozilla Firefox, subscriptions for other browsers work ok! I can't understand why the subscription disappears in Firefox? I use same script for all browsers, what is wrong with it in the case of mozilla, I can't understand. Thank you in advance for your help!

Am using Firefox 80.0.1 (newly updated) and Linux Mint 18.3. I have a problem with HTML5 and also codecs problems on at least two other sites (my daily newspaper and The Register). The problem existed even in the previous Firefox version. If I use Chromium these videos work. The newspaper problems give the message that the browser can't play any of the available formats - code 12. I checked the web console ans there were many messages. I had logging allowed and set to the clipboard (gpaste) but nothing turned up there. I did a screen shot which is a png. I copied the results here. Missing codecs video/mp4; cidecs="avc1.42E01E mpra.40.2". This works in Chromium. As far as I understand HTML5 should work in Firefox. I've seen 2 places where it doesn't: live streaming from World Science Festival and from metopera.com. I've seen the problem once on youtube however I could view the same video later with no problem. As for the missing codecs I can live with using Chromium in the 2 cases the problem has shown up. But I would like some clarification on the HTML problem.

Hi all, Has anyone know how to uninstall Firefox via SCCM using the a command under the Deployment type or any other way using an application deployment?

Any tips welcome!

Thank you,

I'm seeing breakthrough of the background when Firefox is open on my second monitor.

This seems to occur when the window on the secondary monitor is minimised, then maximised and mouse over the image on the secondary monitor (second is right hand side) - see image.

Initially I thought this was a graphics issue but this does not occur when I repeat the steps with other applications. I have also tried it with Chrome and Chrome does not display the same behaviour. I do not see this behaviour on the primary monitor.

I have reduced the refresh rate from 144Hz to 60Hz and reset Firefox which has not cured the issue. It appears to me that the only application that exhibits this behaviour on this machine is Firefox.

I also started to see this occur on my previous machine which was based on Mint 17 and a different Nvidia GPU and monitors and had been stable for many years.

If there is any further information I can provide, please let me know as I'm loathed to change from Firefox as I've been a fan for many years.

Hi, I want to disable Firefox gmail notification when receiving a new mail with sound and notification prompt throught dunst. I found out that the gmail notifications run in background of firefox.

I'm running Arch 5.8.3, dunst 1.5.0, Mozilla Firefox 80.0.1 Any ideas? Thank you.

I have a new HP printer and I am using Firefox from a Windows 10 PC. I am plagued with Paper Mismatch errors when printing emails from Firefox. After a lot of trouble shooting, I have found that this problem seems to be confined to Firefox, as it does not happen when using other browsers, e.g. MS Edge. I have tried resetting all Firefox printer settings and the problem still happens when opening Firefox in Safe Mode.

The print job stops with the error message Paper Size Mismatch after the 1st page, and printing will not continue or even move on to the next job until the error is cancelled from the printer's control panel. This means I have to be working next to the printer and cannot print remotely.

In the printing dialogue box under Printing Preferences, the paper size shows Letter, whereas I am using A4 in the printer, and this is the mismatch causing the problem. I can change the paper size in Printing Preferences from Letter to A4, but I have to do this for every job seperately as the paper size setting always reverts to Letter. This is totally impracticable.

Regretably, I will have to stop using Firefox unless there is a solution. Can anyone help me to change the paper size setting to always default to A4, please? Thanks in anticipation.
