This happens far too often, in the course of 9 months or more frequently. What is going on Firefox? v88.0.1 Windows 10

Constant script errors that freeze whatever program I am in, regardless of the option I choose - the popup no longer gives me a WAIT or STOP IT. The box comes up that says DON'T ask me about this again.

I do not want to copy passwords, more than anything, should I create a new profile. I do not want to deal with replacing or losing the file. When I attempted to load two other profiles over the last two days, both times FF crashed. I gave up.

I am NOW in Safe Mode and without errors, and it's hard to know which app is causing the problem.

Is there a new addon that will back up Firefox these days?

Suggestions? Seriously, FF seems to be a whole lot more trouble these days than she is worth.

Thank you.

Tried to reset settings. Does not work. Went to about:config, than tab.mo / print.tab_modal.enabled set to false. Did this method before and it worked. Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

A folder in Bookmarks disappeared AGAIN! This is ridiculous. Every now and then Firefox loses a Bookmark folder. To make matters worse, I can waste a lot of time trying to find it and get no where. I have better things to do than trying to find lost Bookmark folders! How can I easily find the very important Bookmark folder quickly? Undo does not help.

FF will now not let me log into a site Ive used many times, Ive cleared the cache, remove data, Im not to much techno knowledge but have done that then gone to saved log ins and removed original log in that was saved, gon back to the (site which is my energy supplier) put in my email, then password all is correct but it just will not open anything the dots on top left of page just keep going back and forth, yet if i go onto IE and log in it comes up instantly, maybe I should change!!

I need to continue to use an application (Web Site) built with Flash Player for the first 3 months of 2021. Flash Player support ends on December 31st 2020. What is the plan at Mozilla in terms of restricting access to Flash Player in 2021? - For example, is there a timebomb in the browser so that Flash Player will seize to work on December 31st? - If not, would Flash Player become inaccessible following the first browser update in 2021? If yes, do we know when date is scheduled for approximately? - Will the behavior be the same for all Firefox versions (Light, Enterprise, iOS, Android, etc..). Thank you!

FFox 92 update today. Menu spacing went to double. No shock there. Found the CSS code below for UserChrome.css and set it up.

EX.

menupopup > menuitem, menupopup > menu {
  padding-block: 4px !important;
}
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;
}

EX:

menupopup > menuitem, menupopup > menu {
  padding-block: 0px !important;
}
:root {
  --arrowpanel-menuitem-padding: 0px 0px !important;
}

But, it doesn't get any smaller than the above 4/8px set up. Bug? Perhaps there's another CSS setting to be tweaked for V 92? I do not have any other CSS for these items elsewhere in my UserChrome file.

Hello dear Nerds

With the last update the Bookmarks have a wide distance when listed. Too wide! I have to scroll down endlessly to find things. Before they were neatly narrow and you could see twice as much. Kindly repair this next time please. Or can I do this? Best Ursula Zürich

I have sent several emails and get no reply, how am I suposed to fix check or see my saved passwords if they all look like this...3b4a3f36-7056-4eee-bcb3-2b0838fa07e1

Using previous advice found for this problem here, I typed the following into Terminal. The results show I have three profiles, which I'll try to explain below.

cd ~/Library/Application\ Support/Firefox/Profiles/
ls -l

drwx------@ 41 abababab staff 1312 Jan 15 13:38 0kr25gzy.default-release drwx------@ 71 abababab staff 2272 Jan 15 13:20 8638osoq.default-1513387167461 drwx------@ 37 abababab staff 1184 Jan 16 13:57 k8u9jknd.default-release-1

I use Firefox as my business email and all was working fine until I upgraded Firefox using my Safari browser and created another login profile based on my personal email. That's when the error 'a copy is already open' began. To solve it, I did the above and had two profiles a 'default' and a 'default-release'. I believe I deleted the 'default', and the problem remained. Then I tried a reinstall, and I suppose that's the 'default-release-1' profile, but I really have no idea. The problem for me is that I need to import bookmarks, the business email account linked to Firefox and Host Gator, and all my LinkedIn, MailerLite stuff. I do not want to lose all this and just do a clean reinstall. However, now because I can't open any version of Firefox, I have no way to access the business emails, etc, so I can't recover the Firefox account linked to this business email and get all this stuff back. And I don't know which of the above three profiles I need to delete to get it all working again. Please help!!!

The ability to edit and customize the headers and footers for printing was one of my main reasons for switching from Chrome to Firefox. Now I can't find where to do this. I don't know if it was a recent update or what but I am using Windows 10 Home. Please help so I don't have to find a new browser.

Posting on behalf of a user who hit the VPN inbound queue with a question better suited for this forum:

The tab bar, toolbar, and address bar placement in my Firefox Desktop browser has recently changed. I have been trying to revert these recent changes as they interrupt my current workflows.

I DO know which prior profile save contains the desired info however, it contains many files and I DO NOT KNOW which files I need for the bars to be restored. If you could provide me the name(s) of the file(s) that holds the bars data, I am probably saved, hopefully saved.

Since yesterday, I did the update to FF84, FF permanently crashs - not even the crash manager opens thereafter. I run FF upon a Windows 10 Home 1909 system. I have tried re installation - no effect I have run FF from a differen Account - same problem I have startet FF in secure mode - same problem

I have found the dump files at AppData\Local\CrashDumps but as FF does not run, I have no idea how to analyze it.

I am in despair and soon so far that I switch to Crome...

Has anyone any idea? Thanks, magu

For the last 1-2 weeks FF has started saving web photo files as .AVIF files instead of whatever extension the photo actually is online. I cannot find anything in the settings to change this. I am not sure if this was caused by an update, or something I did.

I am using Win 10 64, FF is version 95.0.2 (64-bit)

Anyone have any ideas on how to fix this? Thanks.

I am wondering if the following is a known problem. If so, I haven’t been able to find the solution online.

I keep copies of home rental online payments as proof of payment should there be a discrepancy with the real estate agency.

This problem can also apply in other situations, for example payment of online purchases, or movement of large amounts of money to varying institutions.

Sometimes the bank payment is delayed and I would like to ensure that not only the date of payment is accurate but also that the time of payment is relatively close. I am finding that the file printed when banking via Firefox is not time dated relatively close to the time of payment. I use Firefox solely for banking as a secure method.

Upon payment I am presented with a bank receipt and an option to print it, all within Firefox’s desktop application. After pressing the PRINT button I choose to print as PDF and save to the computer. The resulting file is what I am referring to.

The pdf receipt is shown with default details at the top and bottom of the page, the bottom being where the date and time of pdf printing occurred. The discrepancy is between that time shown and the actual time of payment. The difference can be sometimes up to 12 hours!

Can someone please assist me to rectify the situation?

Kind regards, Harauld

I'm on the latest version of Firefox, and it's unable to play videos on Amazon.com & Netflix.com. Neither did the one before 96.0. I first saw this on Netflix.com and when the tech started asking questions about my operating system, I knew they had pulled a fast one. Now Amazon.com has done the same thing with Firefox. This browser should be hiding the underlying operating system, because it's not necessary. I can use both websites with Chrome and have no issue. The same version of Firefox is on my laptop, but it has no problems because that thing is on Windows 10.

I won't bother with all the nonsense written about troubleshooting, because this is strictly the functionality of those websites peeking under the browser to check the O.S. Firefox needs to fix this hole immediately! You're messing with my money now. Monopolies shouldn't be able to control our hardware like this; they're not paying for any of it.

Oh, my TV is having a problem with the apps, so I was forced to watch videos with my computer instead. My laptop screen is too small and can't have my booming speakers connected to it. My desktop monitor is 34".

Trying to set up HTML5 peer-peer video conferencing. Its working on Chrome but not Firefox. I have looked at all the available solutions. I have reinstalled firefox; I have checked that media.windows.foundation is set to "true"; I have checked in "safe mode".

This challenge is an issue which occurs 90% of the time. I have yet to assess what conditions occur when html5 video is finally displayed. I can only say that display only occurrred once today and that was when I first inspected the site this morning.

This situation is occurring both in Firefox and the developer edition. Firefox is latest edition and there are no plugins

Any suggestions?

Yahoo intruded and functions as default search, even though Google has been and is still designated as default in the settings. I removed Yahoo from the list of 1-click browsers, but that didn't affect its unwanted function as default search. This began out of the blue several days ago, and I have no idea how. I dislike Yahoo in general and have not been on that site. I'm getting really frustrated!

since yr last update i have lost all my tabs, settings, and pinned tabs, what is happening can you help me stabilize this and i can not get any o\lfd them back from history as every time i open firefox, a second window opens and then keep cycling thru all the pasty websites i have visited and i cant stop it

I have owned my Mac Book Pro since 2014 and I inadvertently re-installed Firefox without knowing a new profile would be created. I am not able to load my old profile into the new one. I can see the "old Firefox data" folder and have tried everything Firefox has to fix this but nothing is working. I have lost 6 years of bookmarks!

Anything other tricks to fix this? Thanks!
