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.

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!

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?

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 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.

Using 2025-04 Cumulative Update Preview for Windows 10 Version 22H2 for x64-based Systems (KB5055612) Firefox 138.0.1 (64-bit) and says it is up todate. I have looked at the about:config to find the browser.tabs.remote.autostart but it does not exist in the list of processes. I have also unchecked in settings both performance options intermitently to try and correct this problem, but nothing happens: (unchecked) Use recommended performance settings Learn more These settings are tailored to your computer’s hardware and operating system. (Unchecked) Use hardware acceleration when available Nothing pops up to allow choosing a different number as many support articles say. I have AdBlocker running as an add on and turned off the duck duck go privacy essentials and still nothing stops these insane amount of processes clogging up my computer. right now, on this page there is only this tab open and there are 13 processes running. Please send real fix instructions- thank you

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 started to use the vertical tab layout because the ability to collapse the tab bar gives a lot of extra screen space to work with on my laptop. I like to be able to split my screen between different apps to work with.

When I try to split screen Firefox with vertical tabs enabled the window cannot be resized down to a little more than half the width of my screen. So it has to take up a just little more than half my horizontal screen space. Even though I can collapse the tab bar to see the page.

Is there a way I can circumvent the unnecessary horizontal window resize limit when vertical tabs is enabled?

Bonus question: When I do reduce horizontal window size it hides the button to collapse and open the sidebar. So I lose a lot of essential control. Is there a way to pin it so it won't disappear no matter what?

The "restore previous session" function stopped working today. My privacy and security sessions are set to REMEMBER HISTORY. I have restarted my Mac. I have the latest version of Firefox. Why does it no longer work?

I had to reinstall Win 11 on a laptop, which required me to also reinstall Firefox. The version installed was 133.0 (64-bit). The tabs are above the address bar. I want them below. I cannot find the browser.tabs.ontop setting in about:config.

Any suggestions would be aprreciated.

How do I get rid of these constant firebox pop ups that block tabs that I have open. it is EXTREMELY affecting my ability to use my laptop. I WANT TO KNOW HOW STOP THIS BS

Firefox downloads .ai files too often as .pdf files, which, although I can open in Adobe Illustrator and/or change the file suffix to open in Adobve Illustrator instead of it automatically opening in Acrobat (unless I right click into Illustrator), is a hassle and concerns me of unintentional file corruption. I don't know why Firefox is downloading .ai files as .pdf files, but it is impractical and frustrating. None of the file download settings I adjusted fixed the issue.

Is this a known issue? The only thread/question I found on this type of issue where files get downloaded as the wrong filetype/suffix was an archived question on .ddd files being downloaded as .pdf files. Please let me know if this is something the devs are aware of and can work to fix it.
