Firefox Community Forum

I've noticed that some websites will endlessly spam the console (in developer tools) with rubbish, and I would like to be able to block that from happening. I'm ignorant about this sort of stuff in general, and it confuses me how a website can even access my browser's console to begin with.

The latest example I came across which caused me to finally ask about it, was some strange JavaScript spam with some kind of < div > (had to edit this with spaces to show it in the post) structure containing over a thousand characters. This entire thing gets spammed in the console at a rate of a few every second. I recorded a short gif of it, which imgur seems to have converted into a video: https://i.imgur.com/dosMZjo.mp4

I use to be able to change firefox icons by adding these files in Firefox under the browser directory

chrome/icons/default/BrowserPreferences.ico chrome/icons/default/CustomizeToolbarWindow.ico chrome/icons/default/default.ico chrome/icons/default/downloadManager.ico chrome/icons/default/main-window.ico chrome/icons/default/openLocation.ico chrome/icons/default/places.ico chrome/icons/default/printPageSetupDialog.ico chrome/icons/default/TabMIxPreferences.ico chrome/icons/default/unknownContentType.ico chrome/icons/default/viewSource.ico chrome/icons/default/Wizard.ico

It worked in version 56 but now in version 97 and this no longer works?

I'm hiding menu items using userChrome.css with option “toolkit.legacyUserProfileCustomizations.stylesheets” set to “true”.

So I am hiding some menu items like for example

1. menu_find { display: none !important }

however though the menu item is gone how do I get rid of the ctrl-F menu shortcut...

I have many such menu items to remove so I need a generic solution to override the short-cut icons associated with the menu items I want to remove

Recently Firefox updated. It cleared all of my bookmarks and browser history isn't reloading my last session. I can get the bookmarks from Chrome. The big issue is how do I reintegrate Avast Passwords eol version? Without this I need to use Chrome which isn't my ideal choice.

How to allow web page to override a keyboard shortcut. Currently firefox picks up the shortcut instead of the webpage...

For example I have an webpage that detects ctrl-shift-h which worked fine in version 56 but now in version 96 it brings up a "Show All History" dialog

I an doing many such things so I looking for a generic way to override firefox keyboard shortcuts

After the last update, the PIP overlay button is different and larger because it contains the message "Watch in Picture in Picture" and when hovering the mouse on it makes it bigger because a second more detailed message appears below the first one.

I would like to make the PIP overlay button as small as it was before with no text at all. What do I have to do in order to obtain this effect?

The background on the homepage link shortcut boxes keeps reverting to black and text underneath to white on my off-white background when a new version loads. I've used Colors to customize the look of my firefox but can't find any control for that. Once a new version kept the boxes white and the text black but now it's back to black again. Where is the control to fix this?

I am currently creating a website in WordPress. It has many embedded YouTube videos.

On pages with embedded YouTube videos, in order to go back to the previous page, I have to click the Back button multiple times. If I right-click on the back button, I see that the page I am currently on has been listed multiple times.

Many other support questions list this issue. I have found that if I disable "Site Isolation" (URL about:config -> set fission.autostart to false -> restart Firefox), the issue goes away.

I am interested, however, in the user experience for those who will go to my site. Is there anything I can do so that "Site Isolation" does not cause this problem?

Thanks, Jeff

I recently upgraded my system and, after installing and using Firefox, I notice the Find (Ctrl + F) bar is now at the bottom of the window. Whereas, it was previously at the top (which is more like every other application I use).

After some head scratching and web searches, I remembered I had to fix this issue previously (after a Firefox upgrade some time back). The method to fix it then could be found here: [there a way to put the Find Bar at top] That link is of course to the same question asked 4 years back.

I have once again followed the procedure there explained per: • Access my Firefox profile folder. In my case:

  C:\Users\<Me>\AppData\Roaming\Mozilla\Firefox\Profiles\5ym42ewi.default

• Create folder therein called ‘chrome’ • In that folder create a file called ‘userChrome.css’ • In that file add text:

  .browserContainer > findbar {
    -moz-box-ordinal-group: 0;
  }

However, after doing that (and restarting Firefox), the Find bar stubbornly remains glued to the bottom of the window.

Can anyone tell me how to solve this issue?

As a separate note to the developers: This issue is long-standing, that a web search reveals is still relevant to many users. Any chance of considering making it a standard option?

I would like to stop the default behavior of firefox displaying in the tab that contains my GMail how many unread GMail messages there are -- in other words to delete "(9)" from the attached photo and never have the count displayed -- if it could instead simply say "Inbox - xxx@gmail.com"

Unfortunately, I downloaded “SaveFrom.net Helper” without reviewing it.

Since downloading it I have been receiving a alerts from “McAfee WebAdvisor” about “dangerous pages blocked”.

I was able to remove the “SaveFrom.net Helper” add on in Firefox, but am unable to remove the “Savefrom.net Helper” bookmark tab which has high jacked my normal Firefox Bookmarks.

I can no longer easily see my Firefox Bookmarks and have to keep opening the Firefox Application Menu, then select Bookmarks, then select Manage Bookmarks in order to see my bookmarks.

Can you please advise how I can safely remove the “SaveFrom.net Helper” bookmark tab which has high jacked my Firefox Bookmarks.

My CSS has always been directed to two effects:

- tabs on bottom - general transparency of the bars

The latest update luckily spared the former, but not the latter! Anyway, this time I haven't been able to solve it on my own, unfortunately...

My current userChrome is:

And my "special" about:config settings, which I've customized over the years to set everything back to how it looked before the progressive updates, are:

toolkit.legacyUserProfileCustomizations.stylesheets - TRUE

print.save_print_settings - FALSE

browser.download.autohideButton - FALSE

browser.proton.contextmenus.enabled - FALSE

browser.proton.enabled - FALSE

extensions.pocket.enabled - FALSE

browser.theme.content-theme - 1

browser.theme.toolbar-theme - 1

browser.download.improvements_to_download_panel - FALSE

browser.download.alwaysOpenPanel - FALSE

Can anyone please suggest a solution? Thanks for your attention!

I was using Ctrl+K on some websites to do things like site-specific search, task bars, and so forth, but recently Firefox started capturing it for focusing on the search/address bar (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_search).

Is there a way to unbind `Ctrl+K` in Firefox?

The mute icon only shows on hover and takes up 50% of the tab size so I'm constantly accidentally muting tabs without realizing it and silencing video calls and the like. The top Google result for this issue -- rightfully yelled in all caps because this is an absolutely horrid UX -- says to set browser.tabs.showAudioPlayingIcon to false, but that does absolutely nothing in FF 100.0

Hi, Could someone tells me how to deactivate the startup popup upon each firefox start which says (translated) "thanks this is 100th version of firefox, start navigation", or is it to stay until the 1000th annniversary ? Thanks

Like the title says, whenever I try to zoom out of an image to make it smaller, it causes the image to zoom out very far in just one scroll "tick".

To be more specific, I'm talking about just scrolling (not using ctrl+scroll). An example would be with Piskel.com where you simply use the scroll wheel to zoom the canvas.

Zooming in is perfectly fine, but when I try to zoom out it seems to zoom out by 3 or 4 ticks. On some websites, such as Piskel, it even it zooms the image out all the way making it very small and impossible to see (It does it with just one scroll tick).

My question is if there is a way to change or fix the zooming, making things zoom out more incrementally. (I recently switched from Chrome which didn't have this problem)
