Firefox Community Forum

Hello, I recently used my MacBook Air to connect with a projector for a classroom presentation. The presentation was using Google Slides. I adjusted the settings to optimize the presentation--setting the navigation and bookmarks bars to hide when in full screen.

I normally use my Firefox browser in full screen mode, but have the navigation bar and tool bar visible.

I cannot figure out how to undo what I did so that my navigation bar and toolbar are visible again when I am in full screen mode. Indeed, when I move the pointer to the top of the screen to make the navigation bar and toolbar visible, I cannot move the pointer back to the navigation bar or toolbar without it disappearing again. Essentially, I need to undo full screen mode.

Thanks, jch

How can you find the place to compose and send an email. This may be the 16th time I've asked. Used to be on the header of the email listing to compose. You clicked it and a form showed up. Now there is no place you can send an email unless you go to the list of all the emails you've ever sent and then send from there. If you have a new email person not on the listing, can you install an app on the header above the inbox email or somewhere like we used to get before you changed the appearance of how the emails look.

Is there some way to enable and disable specific config settings , on a per-site basis?

For example, let's say I want to disable right-click hijacking (dom.event.contextmenu.enabled) on turtlesaregreat.com, but use the default settings everywhere else.

The Page Info > Permissions panel has some, but not all the ones I want. Is this somehow built into Firefox, or maybe there's an extension?

Thanks.

FF120 on Sonoma

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

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.

I've always liked the Firefox New Tab page, with Pocket, and until today, DarkReader plugin has always worked. But now it says that it can't because the page is protected.

I tried the solution to use bookmarklets, suggested in https://support.mozilla.org/en-US/questions/1350781, but it didn't have any effect (https://sanketmehta7.github.io/DarkMode-JS-BookMark/

If I can't find a solution, I'll just ditch Pocket, and use Google as my first page, or something. Or maybe ditch Firefox, which doesn't seem to think that dark mode is important. I don't like being blinded by the light.

Why can't you pin the extension 'Tiny URL' to the toolbar any more?

This extension is really useful! I don't want to have to excavate Firefox to use it.

Tiny URL is more useful than the rather silly 'Pocket' which just seems to be a page full of adverts

Hello there, Iam facing a problem with changing Firefox homepage background. I tried every solution, tutorial, oldposts etc. nothing seems to work, here is what I tried. -1- The chrome folder is in the right folder. -2- the naming of both CSS files userChrome, userContent. -3- enabled CSS files at startup -4- search for both CSS files in the browser toolbox for some reason I cannot find both CSS files, even though they are in the chrome directory. Also, I have 2 chrome folders one of them is located here. "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\storage\permanent\chrome" the other one I created myself which is here "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\chrome" I tried to delete the first one but I cant, I get an error that this file is being used even though I did close Firefox. What I am missing here?

Installed Firefox 122 in a new Windows 10 installation and added some extensions (e.g. Gesturefly, Update Scanner, uBlock Origin, Uppity). These pinned fine on my old installation. But I cannot find how to pin them on the new.

All the help I have found Googling, or using search here, says go to the Add-ons Manager page and right-click the extension and use "pin to toolbar". Alternatively click the extension and click the gear icon and use "pin to toolbar". But when I right-click there is no pin to toolbar context menu entry. If I left-click the gear I get "Check for Updates, View Recent Updates, Install Add-on From File, Debug Add-ons, Update Add-ons Automatically, Reset All Add-ons to Update Automatically, Manage Extension Shortcuts". If I right-click the gear I get a line of icons (left, right, reload, star) followed by "Open Image in New Tab, Copy Image Link, Email Image, Save Page As, Select All, View Pate Source, Inspect Accessibility Properties, Inspect (Q)". If I right-click the extension in the Add-ons Manager page itself, I get a very similar list. In no case is there a pin to toolbar option.

How do I pin an extension, given the above? What have I messed up?

I have a desktop and a laptop. Desktop crashed, so rebuilding.

Firefox on both, settings same on both. On Desktop - Last Pass will not appear. On laptop, same as it always has been.

Image below from my Desktop without the Last Pass icon there.

I've downloaded the LastPass Extension from Mozilla a couple times.

Help, please.

Very weird.

Please provide a native way to change the behaviour of Ctrl-W. I tend to switch between aZerty and qWerty keyboard layouts, as a result I sometimes hit ctrl-W when I would like to ctrl-Z some change. As a result I tend to lose some work when the tab I'm working in closes. It would be nice to be able to rebind some of the default key combinations, or at least disable them.

I found a method description that edits the omni.ja file, but also that this method is unsupported. Moreover, running ubuntu kind of rules this out as an option, as canonical has ruled that firefox is to be installed via snap, in a read-only data store.

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 want to uninstall and maybe re-install some add-ons. But when I goto the add-on page. It just appears blank. So are some other pages in the support/ help sections. Another most notably, is (via menu) help -> more troubleshooting information. It just sends me to a blank page! See the uploaded images for the pages I get send to.

Help please with changing my add-ons

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

I had to Restart/Refresh Firefox because I lost my dropdown menus and then the Google Search bar in the right-hand corner disappeared. Somehow I got it to reappear but it's too small. I followed steps in several different posts and can't get Google Search Bar to widen. 1. I placed the mouse pointer between the search bar and the address bar and nothing happened. 2. The following didn't work for me because I can't find the “Use Small Icons” box: "Click the “View” tab on the program menu and choose “Toolbars.” Select “Customize” from the fly-out menu and a “Customize” toolbar screen loads. Deselect the “Use Small Icons” box and click “Done” to enlarge the icons on the Firefox toolbar." I attached a screenshot of what FF Browser looks like.

Whenever I log on to my bank's web site, I'm sent an audible signal that invites me to start a chat session with a bank agent. The problem is that the audible alert is so loud that it startles me. This is very annoying. I called the bank's help line and was told there was no way they could adjust the sound volume. I would like to know if it's possible for Firefox to decrease the volume for that web site.

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!!

Hello folks

According to Firefox help pages, pinning an extension to the toolbar should work as follows:

"Click the extensions button (jigsaw puzzle Fx109ExtensionsButton icon) in the toolbar to open the extensions panel. Each extension in the panel has a menu button with a gear Fx91GearIcon icon. You can use this menu button to manage those extensions."

The extensions button doesn't seem to work like that for me. When I click the Extensions button I get several buttons (Recommendations, Extensions etc) on the left side of the page as in the first image attached (Firefox1).

If I then click the Extensions button I get to the Manage Extensions page, and if I then click the 3 dots (...) button on (say) Proton Pass I don't get a Pin to Toolbar option and clicking the Manage option opens the Proton Pass Details page (see image Firefox2) - none of the buttons on the any of the pages offers a Pin to Toolbar option.

Those extensions that are pinned to the toolbar, such as Adblock Plus ( see Firefox2 image), got pinned during installation and not by using the extensions button. Currently I seem to have no way of interacting with any extension via the extensions button.

Could be I'm doing something silly but any suggestions would be appreciated.

Regards Ken
