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

I'm trying to perform the clean reinstall for Firefox on my computer. But, I see the instructions for the uninstall, Delete the Firefox installation folder, which is located in one of these locations, by default:

   Windows: (Note: Check both folders.)
       C:\Program Files\Mozilla Firefox
       C:\Program Files (x86)\Mozilla Firefox 

Being I'm not computer wizard I had trouble finding the location of such folder. But when I accessed my program list in my windows program list I see a program named Mozilla maintenance service. When I click on that I see a format/window to "uninstall C:\Program Files (x86)\Mozilla Maintenance Service\." Is this the program/folder I need to uninstall to complete the proper instructions I need to perform a clean install? If so, when I delete it I then reinstall Firefox once again after the uninstall procedure? Is performing the uninstall procedure going to screw up my Firefox browser and my many bookmarks I have accumulated over the years? Can someone please help and explain? 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.

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

Several weeks ago, because it seemed to be a Gmail-tab-only problem, Firefox Support advised us to contact Gmail Support.

It is now clear that the problem is with the Firefox browser. The attached screenshot shows an example of an affected tab.

Please fix this. Multiple versions of the same tab waste RAM and other memory, especially on a limited-memory device such as a laptop.

For the past two weeks, I've noticed that embedded maps make my browser immediately crash. I initially thought it was a Firefox problem, but I have been having a similar issue with Safari. This does NOT happen on my iPhone using the same two browsers. This also does not seem to effect Google Maps or embedded Google Maps, but embedded maps from other services. Anyway, I'm posting here because Firefox conveniently provides crash data, I'm not sure what else the cause could be and I'm hoping someone can help.

Two websites this has been consistently happening with are The Empire State Trail bike path (https://empiretrail.ny.gov/) and a NYC vaccine finder website (https://vaccinefinder.nyc.gov/). Firefox immediately crashes, though with the EST website it seems to be tied to the pathway of the trail being drawn (crashing after I've zoomed in a few times and the path has to regenerate). Safari doesn't totally crash, but forces a site reload and after it fails a second time says it can't display the site.

Any ideas what the issue could be? I'm on the latest version of Catalina (10.15.7), Firefox and Safari and seem to have all security updates for all.

Here's a link to the latest crash data: https://crash-stats.mozilla.org/report/index/1389c870-51cf-4790-b0a0-fd01f0211202

Ok, this might be REAAAAALLY weird that i'm talking about a firefox version that was released in 2012. But i really need it on this windows 2000 VM. The problem is firefox 9 - 12 is not loading any websites or webpages. It crashes instantly upon opening them. Versions lower then firefox 9 - 12 work flawlessly. Probably nobody will answer this but it is really important for my VM.

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.

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

1. I've performed a completely clean uninstall of Firefox and then reinstall
2. Cleared all browser history/cache
3. Removed all extensions
4. Disabled IPv6, HTTPS Over DNS, No Proxy
5. Ran through Firefox's troubleshooting
6. Used Firefox Troubleshooting Mode in the Browser
7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

• Windows 11 21H2 2200.348
• Network driver is the latest Win11 edition
• Firefox 95

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.

Firefox 100.0 (64-bit) Mac desktop: Apple Silicon Mac mini (M1, 2020) - macOS Monterey v12.3.1 (problem occurred prior years using Intel/iMac 2015; and previous macOS) Extensions: DuckDuckGo Privacy Essentials; HTTPS Everywhere; NoScript Plugins: OpenH264 Video Codec provided by Cisco Systems,Inc. Location: Australia EST

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

Greetings everyone,

Firefox is my preferred browser and I really prefer the Firefox Engine over Chromium that most other browsers use.

I want to install a backup browser that runs the Firefox Engine in case my Firefox browser has a problem.

I searched a lot and I thought installing this would be the best option: https://www.mozilla.org/en-US/firefox/developer/

However, I’m worried that installing the Firefox developer edition will change my Firefox installation…

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".

'Release 96.0.1 Does Not Work with Our Ariba PunchOut Catalogs' Users can punchout and add items to the Shopping Carts, but when they try to return the items from the cart back to our local Ariba Application, users receive a "Token Expired" error. When they click the button to return to the Ariba application, there are no items in the requisition.

We experienced the same issue when Chrome released version 80 in February of 2020. We have been recommending Firefox as the preferred browser but now it has the same problem.

Can you provide some way for users to run an older version of Firefox? Version 95.0.2 Works great. I have not upgraded to 96 yet due to this issue. However, many campus users have already installed 96.0.1.

Currently in our environment, only Inernet Explorer or EDGE running in IE mode work with our Ariba Application. Should we advise our campus users stop using Firefox now?

I'm using freshly-downloaded Firefox version 102.2 on a brand new laptop (Windows 11 Pro version 21H2), and every single extension is showing a "Installation aborted because the add-on appears to be corrupt" message when I try to install. I have tried checking for updates, quitting and reopening firefox, restarting my computer, refreshing firefox, uninstalling and reinstalling firefox, as well as any and all combinations of those. I've scoured these message boards and nothing is working for me. Please help!

When downloading my Audible Library via Firefox (latest update) tha downloaded fies in AAX format, are appearing in my Downloads Folder as .MP4 format. Convertion to MP3 works, but is messy. I`m informed by Audible Support that the fault lies with Mozzilla.! Regards, Tony Jackson

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.

Since upgrading to Firefox 99.0.1 when I bookmark a web page into a specific folder, the URL does not appear when I open that folder. A restart of Firefox does not fix the issue.

But if I try to Bookmark the same page again, I am asked to edit it. So it must be in the folder but it is not visible! Help!
