I-Firefox Community Forum

I'm a recent reluctant user of Windows 11. I can't get Firefox configured the way I like it on the new Windows 11 machine. Every single time I try to find an extension, I get a message "Gah. Your tab just crashed." I've tried the Restore This Tab option to no avail.

I uninstalled Fx, downloaded a fresh copy (using Edge, ugh) and installed it. I get the same result.

I had Fx running on the Win 11 machine, before I foolishly accepted an upgrade that took me to Win 11. I suspect that there might be a corrupted Profile or other vestige of that Firefox installation that is causing problems. (Or, because I used Edge to download MSofat hacked me.)

Can someone please tell me how to find and remove all vestiges of Firefox? I want to get back to a fresh slate and try again.

I'm posting this from my old and slowly dying HP laptop running Windows 10. Fx runs here, but the system is slower than Christmas to a 9-yo.

TIA

cannot download firefox browser because I have an expired chrome browser that I'm supposed to delete first -

However - have tried a dozen or so ways to do just that - or so it appears and still cannot download the

firefox browser and after much frustrated key pounding find evidence chrome is not really deleted - help losing

my mind - I'm 77 years old and not computer literate but not senile either - i hope

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

Hi everybody. Thanks in advance for your help.

I'm on Win 11 23H2, and I'm currently running Firefox 88.0.1 x64. Why? Because it's heavily customized to suit my needs. Some examples:

• Extensions (e.g. Classic Theme Restorer)
• userChrome.css and userContent.css customizations ( https://github.com/aris-t2/customcssforfx ), which include tabs on bottom (mandatory for me), tab height/width, and many other things.

I decided a long time ago to stay with v88 because every new Firefox update was breaking things that I needed, and I got tired to spend hours with every new update. If only Firefox devs could find a way to NOT break user customizations with every new update...

Of course I'd like to update my Firefox to the latest version. But I know that it's going to be a nuclear bomb. I already made a test. First I made a backup of my profile folder, then I just updated Firefox. Suffice to say that not only all my customizations disappeared : even my tabs disappeared, and I have dozens of them. So I had to uninstall everything, copy back my previously saved profile folder (because of course it had been modified by the latest version), and reinstall Firefox 88.0.1.

So here's my plan and my question. Would it be possible to have two different Firefox installs (not portable I guess), with two different profiles, running at the same time?

• Here's how I see it:
• Download Firefox latest version
• Close Firefox 88
• Move profile folder away from AppData\Roaming\Mozilla\Firefox\Profiles, so Firefox latest version can't find it
• Move Firefox folder (the one within Program Files) so hopefully Firefox latest version can't find it
• Install Firefox latest version (it then creates a new user profile folder)
• Start Firefox latest version
• Move back the old Firefox folder to Program Files (so there will be two different Firefox folders, e.g. "Mozilla Firefox 88" and "Mozilla Firefox")
• Move back the old profile folder to AppData\Roaming\Mozilla\Firefox\Profiles (so there will be two different user profile folders)
• Start Firefox 88

Would that work, or am I missing something?

If it worked, then I could keep working on Firefox 88, while gradually customizing Firefox latest version until it's ready to take over.

Thanks in advance for your insights!

My computer updated with no warning one night, and i lost all personalization and even everything stored in my firefox, the sign ins, passwords, bookmarks, all. is there a way for me to find all that was erased?

Files will not download. The file is a rfa(revit) file. This is my second day using this web browser..

I have checked setting, to which I switched around to try and troubleshoot. This did not work. I ended up downloading another browser and the file downloaded no issue. Why is this happening? Ant help is greatly appreciated!

I'm using this instructions to move my profile from old laptop to new laptop. I've had success with this method in the past, but not today. I copied the files over to my new device, open FF on the new device, and FF just opens as a new installation. What is going wrong?? (I'm going from a Windows 10 laptop to new Windows 11 laptop. (Ugh, I already haaaaaate Windows 11, but that is for another forum!)

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

Hello,

So, I tried to download a video from my YouTube Premium Account. According to the youtube webpage, that video was downloaded to my iMac. My FF 124.0.1 settings are set up to download to the Desktop. I am running Mac OS Sonoma 14.4.1

Yet the file is not there. I tried searching on the Support page for FF. Lots of articles but no real help. Tons of info about how to tweak the download but Nothing about Where that download ended up. I did give Permission in Settings for youtube.com to download to my iMac, but again, I can't find the file. In the Storage section, it shows 37.5 MB, so it should be on my iMac, right?

How is it possible for youtube.com to show that I downloaded the file but I can't find it?

I am totally at a loss. Never had anything like this happen before. Prior downloads have Always shown up on the Desktop.

Any thoughts? Thanks for your time.

I just installed Firefox on a new Windows 11 desktop computer. I ported my profiles over and it appears everything came over EXCEPT: - Themes aren't working. I've tried switching them and they still don't display. The menu bar is black w/white letters; the toolbar is gray with white icons/letters. - My extension icons are there...sort of. If I hover over them I can see the tool tip but the icon doesn't appear on the toolbar which is light gray in color. I can live without the themes if I have to. Not so much the invisible extension icons. Any suggestions as to how I can get them to appear as they do on my Windows 10 desktop? Screen cap below. Cursor is hovered over the Undo Close Tab extension icon but where's the icon? Any suggestions as to how to troubleshoot this will be appreciated!!

All of the files I try to download fail immediately. Even extensions will not download on firefox. I have uninstalled and reinstalled and checked the download location. Downloads work on other browsers such as Chrome fine but nothing will download on Firefox.

Hello,

In the past, FF downloaded documents without opening them in the browser. This is two weeks now that whenever I download a document, FF is now opening the document in the browser without asking me.

I welcome if someone could tell me what I can do to stop FF from opening the documents.

Thanks for any help you can offer me.

I will be receiving a new HP Laptop to replace a 2013 Dell Inspiron desktop and would like to to transfer my Firefox browser, settings and bookmarks when it arrives in a couple of weeks. Can you help with the easiest way for me, who has some knowledge but not the greatest at Tech. ? Thank you !

I wish to export, and not copy, a digital certificate so that I can import it to Keychain on my Mac. The only option in Firefox Browser on Mac is to copy, which means it only opens as a TextEdit and cannot be imported.

Any recommendations?

I am using Firefox on Linux. Version is showing as 114.0.2 when I do firefox --version. The display in the Firefox windows is completely messed up. Can't show what I mean as I probably can't get a screenshot. Is this to do with hardware accelerated video? These messages appeared when I tried it from the command line: "[GFX1-]: glxtest: libEGL missing methods for GL test Missing chrome or resource URL: chrome://global/skin/icons/warning-16.png" It starts and then has very high CPU. I had to reboot. I may have added something to the config in the past, using the GUI, but can't remember what I did, maybe to do with the hardware acceleration, thinking I could try seeing if it would work. I tried a few things adding these lines to a user.js file in the profile folder (something I found online):

"user_pref("browser.preferences.defaultPerformanceSettings.enabled", false); user_pref("layers.acceleration.disabled", true");

This has not helped. Is there anything else I can do?

After wipe of drive and reinstallation of Ventura by the Apple Store, and migration from Time Machine, Firefox won't launch. It's there, but it won't open. Click the icon and the icon moves as if it were going to launch, but the app doesn't open. If I were to reinstall Firefox, would it sync with my settings and Bookmarks?
