Online forms don't appear in Firefox (Windows 10 PC), but do appear correctly using Edge or Chrome. This has been happening for quite some time. I have o switch to Edge or Chrome to see the fields to fill in on online forms.

I started getting this message today - "this page is slowing down firefox. To speed up your browser stop this page" How can I fix it other than to start using Safari.

Suddenly almost everytime I load a YouTube video I have to watch 2 - 4 min of ads, sometimes two in a row before the video starts. I no longer have the skip ad button. If I load the same link in Chrome or Edge I don't have this problem. My search engine is Duck Duck Go, but if I go to Google first and then to the video I still have the problem. I also have the Maleware Bytes ad blocker installed. Any suggestions?

For some reason when I try to download a screenshot of [this tweet] it fails every time; I tested it and it's just that tweet specifically. This has never happened before and I assume it's just a bug since copy-pasting still works. Any help with this?

This is the message I get. "Please unblock challenges.cloudflare.com to proceed." I can do nothing.

Things I've tried. Adding exceptions in the privacy settings in 2 seperate areas. Resetting Browser deafults. Turning off all vpn's and addons.

Nothing works.

When selecting "Open in Firefox" in the "What do you want to do with this file?" box or on about:preferences and then opening a PDF file on the web, instead of downloading the file to RAM and opening it with its online address, Firefox downloads the PDF to /tmp/mozilla_${USER}0 and opens it from there. This also adds it to the download history. I have set the about:config flag browser.download.start_downloads_in_tmp_dir to true so the files I just open and don't want to permanently download don't clutter my $HOME/Hämtningar (downloads) folder. I tried to first prevent that by selecting the default action to do when tasked to open a PDF, but that didn't fix it, so I set the about:config flag. Unfortunately, setting the default action stopped Firefox from opening a PDF inline without downloading it and I cannot find any option along the lines of "Preview in Firefox" (as described in this support article ).

Can not login to my PNC Bank after Firefox update 121, another computer could ling in until it to was updated by 121. I can login with Edge. Windows 10 (up to date), 64bit, Intel(R) Core(TM) i7-5930K CPU @ 3.50GHz 3.50. I get, see attached screen shot, only when using Firefox 121.

I had ~500 saved logins on Firefox prior to it updating to version 121.0 - now I have 15.

Firefox Lockwise app on iPhone still shows all my saved passwords.

How do I get these back and why have you deleted them?

With 'Back up your Firefox data' it says it saves all open tabs.

What is meant by 'open' tabs? Is it tabs that I have clicked on during my session?

I have just over 300 tabs, will Firefox save all of those tabs in the cloud or only the tabs I clicked on during a session?

I am trying to migrate from a very old version of Firefox (v. 55) to the current one, but there is an app that is more helpful to me that all the other features combined. That is the "Tab Grouping" app that will not run in any version of FF higher than v. 55.

In my work, which often includes a tremendous amount of research, I need to be able to quickly go from one group of tabs to another. If I had to open all these sites manually, that would take the better part of the day and frankly I don't have near the mental capacity to remember the tremendous number of tabs. I have had a couple replies (Thanks!) to this question sometime back, but unfortunately none were even close in performance.

So, can anyone direct me to an app that will allow very quick movement from different sets of windows/tab groups (please see screen shots below)? Is there anyway that I can get this app to work in Legacy mode? I have several other old apps that work perfectly well in this mode.

On all sites where I need to login with my work account I get a tab crash when the browser redirects to https://login.microsoftonline.com/ac4b0eb0-811e-4ab0-acca-8a87079290dc/oauth2/v2.0/authorize?response_type=id_token&scope=user.read......

This is a recent failure (this week), that occured without any changes on my own account to Firefox developer version 121.0b2(64-bits)

I had to install google chrome to overcome this problem. Chrome has no issues with microsoft authentication.

Please solve as soon as possible, otherwise I will be switching to another browser.

I am unable to install the Bitwarden extension (attempting to do so from the extension's official Firefox page). After prompting me to allow the add-on to be installed, the process hangs. Clearing all data did not help.

Running Firefox 121.0 64-bit on Windows 10.

Thanks.

Hi, I've been using Firefox on all my devices for YEARS without any issues. However, as of recently, I had moved into a new apartment, and with that came a new internet connection, which was very slow since the beginning, but usable.

At first I had assumed that Firefox on my PC was loading websites more slowly because of my poor internet, which was partly the case - however, my laptop and Android phone were on the same network as the PC and were both much faster. So I assumed it had something to do with the differences between WiFi and Ethernet connections - the PC was plugged into the latter while the laptop and phone were using WiFi.

But then I noticed that Firefox was the only program with lacking speeds. Spotify loads video podcasts with no problem, Steam downloads are relatively fast (as much as my network allows), only Firefox took MINUTES to load a simple web site. For example, I tried opening Reddit on my PC to write this post, gave up, and am now writing it on my phone. The Reddit website is still loading on my PC as we speak.

I honestly don't know what could be causing this issue. I checked Task Manager, and Firefox isn't using any more resources than it normally would. I am also using the latest version, I just checked.

Any ideas or fixes? Even diagnosing the problem would go a long way.

I have a Lenovo ThinkPad X1 Yoga Gen 6 (20XY005MGE) with Win11 Pro.

All of a sudden, Firefox does not play any sound. I notice that it does not show up in the volume mixer. I tried:

• this solution: https://support.mozilla.org/de/questions/1278299
• Reboot the PC
• Uninstall and reinstall Firefox
• Deactivate all Extensions
• I worked my way through the manual pages (none of which mentions Firefox missing in the volume mixer)

Youtube does not play sounds, the Spotify page notices that it cannot play sound (the spotify App for Windows works fine, though). News sites (tagesschau.de / video, deutschlandfunk.de / audio) play the video, but no sound.

I had the problem a few months ago already but I cannot recall the solution :(

Thanks for helpful hints!
