Diễn đàn hỗ trợ Firefox

I have been fixing dozens of problems with 140 ESR's GUI. Earlier today I fixed almost all of the problems with the search panel:

Except one: I do not know how to detect when the default search engine has changed. I need to know how to detect when the default search engine changes so I can update the favicon and placeholder text by recalling my gui_fixes_search_favicon() function in userChrome.js.

I'm an experienced web developer of 20+ years and would be grateful if someone could share their insight without the often "obligatory" cautionary tales 101 bit. Thank you in advance!

I use the same laptop at two locations. I have different printers at each (both HP, one a laser the other an inkjet).

Most of my time is at location 1. Typically I can print without a problem. Recently in Firefox ONLY I have been unable to print at location 2.

Scenario:

1. I print to the laser printer at location 1. No problem.
2. I go to location 2 and choose to print - the print dialog appears with a "spinner" and it does not go away.

I have to cancel using Esc. I am unable to print at all from Firefox. Typically if I close Firefox after that, it looks closes but is still shown as running in Task Manager.

Other programs such as Word and other browsers bring up a dialog box showing that "the printer cannot be contacted" and allows cancellation. At this point I can choose the local inkjet printer and all is well.

HELP!!!!

A few days ago I started getting the below message when logging into my AMEX account. Any ideas how this can be fixed?

Hi, I can't get youtube to load using firefox. Every other site load but youtube. I restore my pc to a later time and it still doesn't load. I up dated firefox and that didn't work. I deleted my cookies and still no luck. Youtube will work on Google chrome, but I don't use that chrome. What do I do next.

for awhile now I am getting this message. I have multiple browser windows open with multiple tabs each. Even if I delete all but one browser window I still get this message.

What can I do to rid myself of this message?

Thanks leon

Mon. 11/10/25 -- Good evening. Periodically, the Wallpaper option that's available when you have a new tab opened is NOT THERE. I've used your backgrounds and sometimes my own. But out of the blue, a new tab will have no background picture and when I use the pencil to open the menu, there are no wallpapers showing.

I don't see a reason for this, particularly since I haven't changed anything and no one else has access. This is a Dell Desktop, XPS 8960, fully loaded, enough of everything and running on Win 11.

So - are there limits to the graphic size used for a background? Would this be caused by a FF update? So many questions, and thanks for answering them.

BTW - I can't select the EM box below, so just send to me at: [edited email from public community support forum]

Hello. Firstly I have NO troubles accessing the internet via Firefox (my Default browser). My problem is that none of my "saved" websites (including those appearing on the Bookmarks Toolbar) will open on the internet when I click on them. If I type the internet address into the address bar, the site opens as normal. I do not have this problem if I use Chrome. The problem only commenced today following an update by Norton via Norton 360. I have attempted all the suggestions that Norton have supplied other than re-installing Firefox - and none of their suggestions have solved my predicament. Any assistance would be gratefully appreciated to fix this most annoying problem. Thank you, Ron.

Hi,

Every time I try to connect to my Gmail account, the browser freezes and I have to restart it. I’ve tried everything, but nothing works. Please look into this — since your last update, Firefox has become unusable.

Thank you for your attention.

Hello,

Does FIREFOX offer an app that will read my email to me? OR (desktop Mac)

I have a DAW (Digital Audio Workstsation) (Logic is the version Apple offers. )and I've purchased many musical apps. Guitars, keyboards, etc but a lot of them have long manuals. I'd love to be able to hear the text, say while washing dishes.

I do have the CC on my television while viewing shows

I'm over 60 and I didn't read as much (as I should have, since I was younger) my reading comprehension isn't that great. Thank you for reading, Roger Erickson

After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.

So I'm just idly doing cleanup / maintenance work on my saved passwords and have encountered the most ridiculous error message:

• Vulnerable Password
• Learn more\
• This password has been used on another account that was likely in a data breach. Reusing credentials puts all your accounts at risk. Change this password.

Except I know the password is unique.

I have a strict username / password usage where every site gets a unique password, period.

Someone broke something in when it calls ABC = DEF

When I check my passwords I get a message saying that my password has been compromised and that the user name is admin. They suggest changing the password immediately but every time I try I can’t figure it out. I can change my password and have done so, but the admin password I’m not sure what to do.

I recently asked a question about having a problem with Firefox not successfully loading a second webpage tab. While it appears to start loading correctly in a new tab the tab remains a blank page and the address window continues to appear that the loading process is ongoing but it just continues to show the apparent loading process but the network has no activity. I tried following some suggestions but to no avail. I then uninstalled Firefox and did a clean, new install. Upon trying the new install it appeared to work correctly at first but after attempted to do a second Google image search, which worked correctly, I tried to visit the site that what contained the original image. The site partially loaded; appeared to keep loading for about 15 minutes; stopped; and I got a partially installed page and even that wasn’t correct as can be seen in the enclosed images.

The 'reader pane' on my microsoft email remains blank. It used to show me the body of the email on the right side of the screen.I now have to open/download the email to read it. Is there a way to resume the prior arrangement?
