So, I just now installed Firefox and now I want to change the background of the home page (new tab), the same way you would do in chrome. I did some research and created a chrome folder and a chromeContent.css file in there.

I tried first the code in this link: https://support.mozilla.org/en-US/questions/1271362 and then this one: https://superuser.com/questions/1495946/how-do-i-change-the-background-image-of-home-page-in-firefox

neither of those worked, even though I'm pretty sure I followed all of the instructions correctly. help please, will be greatly appreciated (i don't know if i chose the correct topic)

pictures included in order: the code (device name crossed out), inside the chrome folder, inside the profiles folder

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.

Somehow I recently added a favorites side bar to my page and not sure how to get rid of it now. Now when I open my saved pages it turns it into a 2 step process. Now it opens up a side bar and then I have to click on the star to open my saved pages. Before I just clicked on the folder and it opened them up. I have searched on help but none of it helped. One solution was to got to settings and to hide side bar but I don't have that option. Tried to customized toolbars, nothing seems to work. I use the favorites all the time and to turn it into a 2 step process is a pain.

When opening several tabs they start to shrink down to the browser.tabs.tabMinWidth for which the default is too small for my sensibility. I've tried messing with it to make it more tolerable but what I really would like is to be able to set the tabs to not change size at all. I would like them to stay the default size. Of course let users have smaller tabs if they like, but let us not if we don't want it.

My second issue is when you have many tabs open and you scroll through them with the mouse wheel, it scrolls 6 tabs at a time per mouse wheel input. I would like it to do 1 tab per mouse wheel input just like if I was clicking on the arrows at the top to scroll through tabs. It just makes sense to stay consistent or to have an option in the config that controls tab scrolling.

These are things users used to have control over and were removed. Unless a setting in about:config was renamed to something weird and I'm just missing it, the settings that replaced these options are insufficient.

Using Firefox 137.0 (64 bit) Win 11 24H2

I have just noticed that the background colour of the sidebar and the customise firefox is a pinkish red. I much prefer them to be white. I cannot see or find a way to change the pinkish red to white nor why this colour has been chosen.

I do have a theme which includes various tones of red. Not sure if this is relevant but if it is, it seems to defeat the concept of having a theme, which I regard as a header that should not affect the body of the page).

Thanks in advance for the help.

Hello everyone!

How I can show only the tab icons on vertical tab? Currently I could solve the issue showing enabling vertical tabs, going to Customize Toolbar and just clicking on Done. But every time I use sidebar (showing bookmarks, for example), the vertical tabs display tab titles again, and I need to repeat the process.

There some way to setup this to always show only the icons on vertical tabs? Thanks in advance!

Is there a way to make the URL high lighting of the domain more obvious? I find that most people can barely see the highlighting and I'd like to make it obvious (bolder and red, or highlighted in yellow, for instance.)

Can this be done via userchrome.css?

Thanks,

Thane

Hello, Is it possible to improve the Thunderbird Android widget? Indeed, when I select the widget and install it on my phone's desktop, it is light. A dark and transparent mode is needed.

Furthermore, it would be useful to integrate Firefox Relay, as this concerns emails.

Thank you.

Bonjour, Est-il possible d'améliorer le Widget de Thunderbird Android ? En effet, lorsque je sélectionne le Widget et que je l'installe sur le bureau de mon téléphone, celui-ci est clair. Il faudrait un mode sombre et transparent.

De plus, il serait pertinent d'intégrer Firefox Relai. Car ça concerne les e-mails.

Merci

Why there is no animation or blur animation while opening the url bar? also the choice of zen modes having animation are not fulfilling the thing. so pls add this.

After a recent update to FireFox, every time I click the puzzle icon to try and Pin an extension to the Toolbar it takes me to `about:addons` instead. In `about:addons` I cannot click or right-click anything and select Pin To Toolbar as I was once able to.

I have downloaded FireFox Developer Edition and the puzzle icon does exactly what it suppoused to do which is to show a DropDown list of installed extensions I can Pin or Un-Pin.

Looks like a bug.

Why is this happening? Please tell me that's not intentional.

Hello,

I wanted to customize my Firefox new tab with a local HTML file, such as "/path/to/my/index.html". It was possible to use this workaround: https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main

Which implied a configuration file (sometimes named "autoconfig.cfg", "firefox.cfg", "local-settings.cfg" depending on the guide since the name is arbitrary) with javascript code. In the new Firefox 136, this code fails to execute due to a new API being used.

If you want to customize your new tab, follow the previous guide, but on the configuration file write this code instead:

// My new tab
try {
  const ff = {};
  ChromeUtils.defineESModuleGetters(ff, {AboutNewTab: "resource:///modules/AboutNewTab.sys.mjs"});
  ff.AboutNewTab.newTabURL = 'file:///path/to/my/index.html';
} catch (e) {ChromeUtils.reportError(e);}

Note that the file must start with a comment

Adapting the "/path/to/my/index.html" to your needs.

Thanks to @mkaply (github) on this thread https://github.com/mozilla/policy-templates/discussions/1190 for the new API method.

I post this here in case someone has the same issue, because is quite recent and hard to find on the internet.

I just want to restore the old functionality of being able to edit addresses in the URL bar but every time I click on it now it opens new tab and I hate it so I try to go to about:config only to discover it's been removed and I can no longer adjust anything to my liking.

Why is Mozilla intent on making this such a bad browser when it used to be the best??

Slowly but surely over time more and more things that were great about this browser have been removed and more and more things are being made worse.

I just want to know why Mozilla is intent on ruining the browser?? I have no hope for you ever returning the functionality and I'm looking at other browsers so if anyone's got a recommendation for something that works as well as Mozilla Firefox used to please do let me know.

Under Customize Toolbar, I want to move the toolbar item "Extensions" off the top menu bar, and into the Overflow Menu, or another area, to make the address bar bigger. When I attempt to move it, there is a ban symbol across it and it will not move. Firefox 127.0.

Hi!

I'm not sure if this is a Firefox problem or not, but every time I try to go the Facebook website I get this error:

"Sorry! Something went wrong :("

And it has been going on for weeks. Sometimes it works in the evenings (UK time), which seems weird but it is rare. I tried troubleshooting mode and it made no difference. Facebook is my sole means of contact with some people, including one or two students (I'm a tutor). I also tried to install the newest version of Manjaro, but it made no difference.

Also, I cleared the whole history, and do that at the end of each day anyway, so that is not a fixer.

The reason why there is any doubt that it a is Firefox problem is that it also happens with Chromium but without the occasional successful connection.

Does anyone have any ideas? And is there any other information that it might be useful for me to provide?

(Firefox 131.0.3 and up to date version on 12/03/2025) (Manjaro 24.1.1 and up to date version on 12/03/2025)

Supplementary note: I won't be able to use Caprine as an alternative access as it has effectively been obsoleted due to it being dependent on Electron29, which won't build for some obscure reason. And no, I don't have a smartphone.

Thank you kindly,

Oliver.

I can only use firefox for 90 minutes at a time, before the entire system crashes.

Since the last couple of updates, the infamous memory leak issue has gotten significantly worse. Now 30 minutes of use with no add-ons sees the memory use swell to 13 GB, crashing the system. Sometimes windows 10 crashes, sometimes it just kills firefox.

The thing is, when I check about:memory, it says firefox is only using 1.5 GB. However task manager says 13 GB, and if I close the browser, suddenly 13 GB memory gets freed up.

Does anyone have any idea why there's such a discrepancy?

Last week my usually reliable 'Thunderbird 115.8.01 on iMac 10.13.6 has suddenly gone haywire.

* In the folder pane, multiple folder duplicates reappearing even after deleting them. (See images) * And when I delete messages, they appear in the trash folder, only to disappear and repeatedly reappear - back into the message INBOX. * Also, after making a change in the Notification section to turn off the notice sound, and although the sound turned off, so did the auto-disappear function. Now I have to manually "close" each and ALL notification notices one-by-one. The new problem is: now the notification option section has disappeared in settings. (No image for this one. Nothing there!) Bug? Or something else?

Please help. P.S. I ran both of my antivirus programs twice. Each over different days and both declared' my system clear and clean.
