I want to delete all my bookmarks at once -- I have nearly 1,500. I already asked this question and the response I got showed me how to do this by selecting each one at a time. I want to delete them all, AT ONCE!

Not selecting each one and holding down the CTRL key.

Btw, I already explained this ... so, is there a way. I've tried uninstalling and reinstalling and not keeping the former settings. But the stupid bookmarks keep coming back!

My page throws errors in Firefox Nightly such as

Expected color but found ‘undefined’. Error in parsing value for ‘background-color’. Declaration dropped. preview.htm:1:1

and

Expected color but found ‘undefined’. Error in parsing value for ‘color’. Declaration dropped. preview.htm:1:1

The page references ten CSS files besides having dozens of its own CSS declarations. The issue is tha the reference provided to the error (:1:1) does not indicate where I can find the error. That is, I don't know which declaration is at fault. Is there some straighforward way to find the declaration in question?

Yet another sterling example of why change is usually bad. Why did Firefox, Google and other browsers (though don't know about Duck Duck Go) drop the 100 results per page option? I've always had that enabled and now that it was removed it makes searching extremely tedious and time wasting. Please offer a SIMPLE AND QUICK way to restore this option ASAP. Thank you.

One of the things I heavily rely on with FireFox is it storing words I type in reply boxes on various forums. Lately however, Firefox only seems to keep them for several hours, then they disappear. For example, I can type in "K Frame." (See image attached) The next time I go to use that field again, that text will automatically appear. And it may continue to do so for several hours, even if I close out Firefox and return later, but eventually, within 24 hours, it will disappear and I will have to retype it again the nest time I want to use that phrase. FireFox used to hold these words or phrases forever.

Any suggestions????? Both my Windows 11 and Firefox are up to date.

The situation is like this: I once reinstalled Edge, and then Firefox disappeared from the default browser options in Windows settings. No matter what I do, I can't make it appear again and set it as default browser. I want to ask if there's any solution, apart from reinstalling the browser,because I have a lot of data in the browser and I'm afraid backing it up and transferring it won't be convenient.

A while back I noticed that my google calendar no longer sends reminders to my gmail (or rather, I suspect, gmail does not receive them). Yesterday I missed an important meeting because of this, so I want to get to the bottom of it. I verified that the reminders are properly set in my calendar, so I have to assume that they are going out. The pop-up windows do pop, so I assume that it is not on the calendar side. I also noted that calendar.google.com and gmail.google.com have the proper permissions to send pop-ups and notifications to gmail, which indicates to me that this end of the equation is working. (Don't know how to isolate the error further, though.) It seems that the Firefox settings need to be changed somehow. Any ideas?

Thank you!

Hi all I like to show the bookmark toolbar in fullscreen mode. I have enabled "show always" but it does not show in fullscreen mode. On old firefox versions i could create a userChrome.css file and then it worked. But it looks like this is not possible with never (130.0.1 ATM) versions. May be the code has changed? This was my "old" css code wich is still working with firefox-esr: /*

  Override hiding of Bookmarks Toolbar in F11 full screen
  when you roll down the tabs/main toolbar 

• /

1. navigator-toolbox[inFullscreen="true"] #PersonalToolbar {

 visibility: unset !important;

}

Hint: toolkit.legacyUserProfileCustomizations.stylesheets is set to true.

Maybe someone has a solution how to show bookmars in fullscreen.

Dear Firefox

I am writing to you as regards your current upgrade and its interface. The taps bar and tools bar are very wide, thus decreasing area below them. The cannot because customized with the little knowledge I have in development.

I jumped FF V90 to this current upgrade FF 131.03 because anytime I tried to upgrade, I find the Interface not to my liking due to what I have already described above. I have seen similar comments like mine on the browser comments. One user actually asked if FF interface to V 80.02 which I support for it is the best of Interfaces so far in the development of the FF browser.

I hope to hear from you soon before I take a decision to go back to FF V90.0.

P/S: My 2 email addresses:

                                            1. [edited from public] @AOL.COM
                                            2. [edited from public] @GMAIL.COM

Also in trying to upload Image of the browser for clarity purpose, I get this:

                                           Error uploading Image
                                           Invalid or no image received.

What is happening here about Uploaded images: Add images (optional), I cannot fathom. There is certainly a block somewhere on the Support page.

Kind regards.

I cannot pin the extension to the toolbar. The extension is not shown in the puzzle icon dropdown, and it is not in the overflow. Please add an automatic pin to the toolbar when a new extension is added! How do I pin it now?

I have every about:config and settings option set to recommended to prevent autoplay videos. NONE work with yahoo. The vids will drop to the lower right hand corner but even if I click on the close window X they still pop open again. And again. And again. Is there a solution to this arrogant, self-centered behaviour by yahoo?

This is a feature request - not sure if it goes here.

I would like to arrange the toolbars in Firefox in the following order:

   Menu bar (top, with "File" on the far left and "X" on the far right, i.e. not centered)
   Bookmarks bar
   Search bar
   Tab bar

This can't be done currently. The best I can do is:

   Bookmarks bar
   Search bar
   Menu bar
   Tab bar

My request is that the user be able to arrange the position of the toolbars in any arbitrary order. Thanks!

I recently added an entry to my hosts file but Firefox seems to ignore it. I'm using v. 128.5.1esr, fully updated. I've tried a lot of the advice online and none of it seems to work. Here's what I've tried:

disabled "Enable DNS over HTTPS Cleared the DNS Cache changed "Use system proxy settings" to "No proxy". tried troubleshooting mode set network.trr.exclude-etc-hosts to true changed browser.fixup.dns_first_for_single_words to true changed network.dns.offline-local to false restarted FF, rebooted computer

It doesn't work in Chrome either, which makes me wonder if it's a Windows 10 issue. Any suggestions?

I have payment methods saved. On payment sites, I click on the CC# input box, and I am given the option to use one of my saved payments. I mouse-over payment choice, and it populates the input boxes with the correct information, however once I actually click the payment method, the payment method and all the input boxes are cleared of all contents. I am therefore forced to enter payment information each and every time I want to use it. The Fill Payment method isn't working.

I have reentered and verified the saved payment method several times.

How can I disable COMPLETELY the tab previews a/when I hover over a tab, and b/ when moving tabs (using left click and hold)? I've tried the various options listed in other questions on the support forum: nglayout.enable_drag_image = false browser.tabs.hoverPreview.enabled = false browser.tabs.hoverPreview.showThumbnails = false

Along with unticking "Show tab previews in the Windows taskbar" in settings.

None of these works to completely disable the previews.

Is my only option to reinstall an older version of Firefox... again?

How to change home page and new tab to desired URL or any extension of Firefox desktop in 2025?

I am unable to find any way to change how my new tab should look when I click + sign or new tab is opened up on browser opening or re-opening unlike Chrome.

I hate the change of position of typing from the search bar on the current new tab to the URL bar (unseen or unheard in Chrome) that Firefox implemented without considering users who would detest it.

How the hell do I remove this crappy sidebar!?!?! Your suggestion of tapping the cog and clicking on sidebar button DOESN'T WORK! REMOVE IT! It is annoying, terrible! Why would you mess with something that didn't need to be fixed ? What are you, Jaguar? Remove it now, actually do something and fix it.

I want to remove the "List all Tabs button" as it's pointless bloat. I am following the instructions on

https://support.mozilla.org/mk/questions/1394194

Which says I should set browser.tabs.tabmanager.enabled = false

I've just upgraded to version 131 and this fix it doesn't work.
