Firefox Support Forum

To you awesome people,

I've experienced this issue in several Windows 10 installations now, different builds, running 19042 currently, Home 64-bit.

My issue:

I can install Firefox without issues, configure it to my taste, no issues on that end.

I choose C:\Mozilla as my install directory.

However, whenever there's an update and I choose to download and install it, it downloads and installs fine, but when I need to restart the browser to apply the update, nothing has been updated.

As in this very instance, it was downloading and installing 82.0.3, but once restarted, Firefox is still stuck in 82.0.

I've not tampered with about:config just configured Firefox in the regular options.

What could be the cause?

Anyone else having these issues?

Thanks.

Firefox has somehow been set to use Alt +Space as a search prompt; see image. I'm not sure how I did this but would like to get Alt + Space back to windows default, which is to control a window Size, Move, Exit, etc. I've tried it with AddOns disabled. Any ideas please?

I stopped using Chrome a while ago and I use, ahem, Bing for searches. Sometimes, when I click on a link I get a "404. That’s an error. The requested URL was not found on this server. That’s all we know." while using Firefox. I copy the link and paste it into the browser Edge and the site comes up no problem. Does firefox used a cached version of Google while Edge does not? Is there a way to resolve this?

I decided to stop using Google some time ago so made the full time change to Firefox and a different search engine. A tad bothersome that Google is still there. Not really interested in going to MS Edge...

Hi, I am an experienced firefox user for more than 2-3 years. But i recently need NPAPI plugins to do certain works. I learned that i need 32 bit to do that. I already have 64 bit. Now my question is can i have 32 and 64 bit at the same time? If i can't, then can i migrate my data from 64 bit to 32 without any data loss? i am free to give further info if needed. Thank You!

Greetings: My computer was shutdown and restarted by a colleague and I seem to have lost my browsing history and all the open tabs from my last session are not retrievable — restore previous session is not available / appears grey'd out. I am on a macbook pro running Big Sur and I do have a time machine backup of that last session — can I get back those open tabs and browser history from my time machine? Can I do it a la carte or do I need to wipe my whole computer and restore from there? Thanks in advance for your thoughts, Sam

For a couple of days I cannot get Firefox to run normally again. It is stuck in a weird looking state as showed in the screencap attached. It opens and I can click on some buttons from the interface but I cannot close it or enter settings, cannot browse or anything, it opens but its functionality is completely broken... I suspect this is following a recent windows update but I'm not sure...

Tried starting it in safe mode and refreshing the browser but it did not work. about:config does not work. I can type in the address bar but when I hit enter nothing happens.

Any suggestions of how could this be fixed without reinstalling it?

Thanks.

My PC crashed and when I try to open firefox I get this error

XML Parsing Error: undefined entity Location: chrome://browser/content/browser.xhtml Line Number 732, Column 15:

I saw this answer https://support.mozilla.org/en-US/questions/1303747 but I don't understand anything from it, English is not my first language. Will I lose my bookmarks and extensions? Do I delete the folders in program files or run the uninstaller? When running the installer there is an option to "restore default settings, remove extensions etc", should it be on or off?
I deleted the folder, ran the installer again and set the option to restore default settings off, and still can't open firefox. Can someone explain in simple terms?

used firefox forever but when updated to new version, it will not get aarp site now? gives me "404 not found". the arrp sites come in fine with edge so it's firefox. also doesn't show my bookmarks on tool bar? help. how do i get my old firefox back?

I have reinstalled my home computer and reinstalled Firefox, logged in and synced. My passwords from my work browser's Lockwise have not appeared or synced. Please advise. Thank you.

I know patience is thin. Feel free to cut to the chase. I did try to self serve and only found export then import options. Are my expectations for sync incorrect?

Happy New Year.

I cannot log into aa.com (American Airlines) with Firefox but Chrome works fine. Error message that their site is down for maintenance but it is up and working just fine with other browsers.

I have cleared cache, cookies, history, etc. HTTPS always is not enabled. Firefox is at the latest version. I have restarted the browser.

Any thoughts?

So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

Hi

I am on firefox desktop Windows 7. I recently deleted my history but I lost all log in details as well

What do I do to get the log in details back ?

System restore somehow failed to restore the system so I am not sure if it works, it would bring back my login details

Thanks

My MacBook Pro hard drive was fried. I have purchased a new laptop. Does Firefox have a backup for those files somewhere "out there" that I can access to download them into the new computer?

Thanx,

John

The options page and addons pages are almost completely unreadable.

For several weeks they have rendered as white text on a very light gray background.

I thought that this was a temporary bug that would be cleaned up in the usual way.

Using 78.4.0esr on Windows.

Is there any fix for this?

It is there whether or not I have my usual theme which I have used for several years now, change to an alternative theme or turn off themes altogether. In safe mode the screens are sometimes usuable but that requires turning off all addons. Doing the same without going into safe mode has no effect on this.

Any advice?

A new feature of firefox 81 says the pdf viewer can be used to fill out fillable pdf forms now. But when clicking on a field on a pdf form, I get the message "This document contains forms. The filling of form fields is not supported". Is there something I need to enable?

Hello,

My time is wrong in Firefox. When I see the time stamps of my productivity on any social or business site, they are about 4 hours ahead. In other browsers (Chrome & Edge), everything is fine. In Windows, my time is properly set. This includes my Time Zone in Control Panel as well.

I have uninstalled Firefox, restarted, and did a fresh install. I am having the same issue.
