Hi Firefox Community -

I am using Firefox 115.8.0esr version. I had previous userchrome.css from older versions of firefox from 5 years back which does not work anymore.

Need userchrome.css content for highlighting background color of bookmarks in dropdown.

Can you someone provide me with this userchrome.css snippet to high bookmarks with background color in URL dropdown box?

Thanks - Tarun!!

I'm using the OneTab add-on, Enabled. The icon no longer shows on the Toolbar, though it is on the Menu bar next to Firefox View.

I ran Remove and then Added it again, hoping the Toolbar Icon would reappear = no go, And I lost all URLs already saved, stupid me. To be clear, clicking the Icon on the Toolbar saves all open tabs.

Is there a fix via Preferences? Thanks. gw

I can't get Amazon back as a search option Bing is one of the search options selected in search settings, doesn't appear.

If I install an older version will it be ok. Why do they keep installing new updates which cause issues with the one I am using. I installed Opera and will give it a try. Firefox keeps changing things that work.'bold text'

Hello everyone,

Why some Wikipedia pages cannot activate reading mode under Debian 12 and Firefox ESR 115.9.1, for example this English Wikipedia page on Emmabuntüs does not allow reading mode to be activated while French, Spanish and German pages can ?

See our test video on this subject: http://share.emmabuntus.org/Accessibility/Firefox_mode_lecture_non_disponible_emmabuntus_en.mp4

Is there a utility to test pages compatible with reading mode?

Or otherwise in which Firefox log file to see if a page is compatible or not?

Thanks in advance for your help.

Hi all!

I am using Firefox Multi-Account containers with Firefox 120.0.1 (64-bit) and the New Outlook desktop client with Windows 10(*). I have more than one Office 365/Outlook account, so I use different containers for each account.

Whenever I click on any link in New Outlook, it opens in one of my Firefox containers rather than in a default No Container tab.

Unfortunately, it opens in a container where I am logged into a different Office365 account than the one I use for the desktop client. This means any Office or organisation-specific links fail to work unless I copy and paste the link across.

Is there some way to force Outlook to open these tabs as No Container?

Thanks, penguinoid

(*) I'm using a university owned/managed computer and they've disabled the option to update to Windows 11

How can I disable the ctrl+t shortcut? I have tried using the Shortkey add-on, but it will not touch the ctrl+t shortcut. It works for everything else, just not that one. I've been told I can modify the browser.xhtml file inside the omni.ja file, but I am finding that almost impossible. Has anyone managed to do this?

Could anyone that uses Ublock please visit here to see if the video is being blocked?

Hi All,

For some reason my tab icons look a little low, and I would like them more vertically centered.

I've been trying to move these icons around using some older code that doesn't seem to work anymore.

The code below no longer has any effect.

Does anyone know how to move the tab icons up 1 pixel?

Thanks!

/* padding doesn't move them */
.tab-throbber, .tab-icon-image { padding-bottom: 4px !important; }

/* margin doesn't move them */
.tab-throbber, .tab-icon-image { margin-bottom: -2px !important; }

/* can't even turn the icons off LOL */
.tab-icon-image { display:none !important; }

I am using Firefox 123.0.0 (rel. 20-Feb-2023) on a Win 10 Pro v22H2 computer.

I understand that FF123.0.0 is supposed to include a new option to "Report Broken Site" on the menu (hamburger icon) that is described in the support article How do I report a broken site in Firefox desktop? but I can't see this new option. I also checked the menu options under More Tools and Help but can't find it.

Exiting and re-opening Firefox didn't solve the problem.

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

I installed one of the ad blockers, I can't remember which one. It's given me so much trouble that I thought to disable or delete it. I deleted the little icon ( a stop sign) that shows up on the far right of one of the menu bars (don't know the name of that bar but here it's the second one down). But websites still complain that I have an ad blocker. I've gone to 'add-ons and themes' but I can't find it. BTW, what's the difference between an add-on, a plug-in and an extension? Which one of those are ad blockers? How can I see and then delete whichever blocker I still have? Without the icon I can't even disable it for individual sites.

After the update to version 123 the cursor in Firefox (Linux version) stopped indicating clickable elements.

I tried the solution mentioned in https://support.mozilla.org/en-US/questions/1434156 but no luck.

Please advise.

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.

Hello, this may not be a problem with Firefox itself at all, but I'd like to try to understand what the cause of the problem I and others are having.

I have Norton 360 installed, in this Windows 10 computer and like to use Firefox for internet browsing, it has always served me well.

I also have Norton Safe Search integrated/add-on to Firefox. This puts a red, green, or gray check mark at the end of each link that comes up during a search and has always worked before.

Recently, I've noticed that such check marks do not appear at all when doing a search with Firefox, but they are present when I do searches with MS Edge.

I am searching for a solution here, and also in the Norton Community. There are others there who have stated they are having the same problem.

Has anyone here heard of this before, would you have any suggestion as to what may be causing the lack of the Norton Safe Search check marks in Firefox searches?

Any input/suggestions would be welcome.

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.
