Firefox Support Forum

Ever since the last update the browser's font has been garbled (tabs, address bar, settings page, etc). Some websites show this problem too.

I tried downgrading back to 119 and it displays fine. I was force updated back to 121 and it's broken again.

I have been using FF for many years but recently have started having issues on eBay.co.uk

At the moment it specifically relates to leaving feedback on my sold items.

I'm currently logging in on MS Edge or Chrome to leave feedback as FF just will not work.

I've tried FF on a clean install on a 2nd PC (no add-ons) and still get the issue.

Please help as I am now having to use Edge & Chrome so much I may as well move over to them which I would rather not do.

We can access the website www.focusadhdindy.com using Chrome, but when using Firefox, we notice that it requires an additional '/' (www.focusadhdindy.com/) to open. Please resolve this issue so that the website can be accessed from Firefox using the link www.focusadhdindy.com without the need for an additional trailing slash.

i was watching youtube when this happened here is the link https://www.youtube.com/watch?v=o25FuR0eUAs the error "your browser cannot play this video"

In the last few days whenever I download a PDF file instead of it being displayed in my default PDF read Firefox (version 121.0.1) takes over and displays the contents of the file. I do not want this, I prefer my PDF reader! How do I stop Firefox trying to take over this function? (other than converting to Chrome)

Is it possible to customize the URL pulldown? When I click in the URL window - I am presented with 6 website options along with various web search options. It would be helpful to modify the options since none of them apply to me. I tried deleting history, playing with the settings/search suggestions/change settings. I want to specify certain websites - and leave it that way. I've tried right clicking the site, shift deleting, contrl deleting. Nothing works. If it is possible - it is not intuitive. I notice that the list does slowly seem to update and evolve depending on where I have been. But I don't want that either. Thx IW

If I go to Safelite and start scheduling an appointment, navigating through that set of webpages will cause my computer to green screen/crash. The landing page at https://safelite.com asks for a zip code, and submitting that form puts you into the scheduling flow; after entering some details about a vehicle, I can click back and continue a few times (less than ten) to make my computer crash. I was able to reproduce the issue in troubleshooting mode. I also tried the same steps in Chrome, but it did not produce a crash.

This computer has had an issue with crashing in this manner for a while now, but this is the first thing I've noticed consistently causes a crash. I'm not expecting a solution, but I am hoping to close in on the issue; whether or not Firefox is the source here is questionable, but it does seem highly entangled.

After after update to 121.0.1 on Ubuntu, I'm not asked anymore for Primary Password at startup, hence I cannot use my saved logins and certificates. If I restart in Troubleshooting mode, I have the pop up for Primary Password back, which is working as expected. Restarting normally after disabled all Add-Ons does not solve the problem.

Been using Firefox for years. Also reading Foxnews. Starting yesterday I cannot post any comments at the site. I can go to Edge and all works fine, so there is something with Firefox that is conflicting with Foxnews. At first I was not able to even read articles but removed all Addon's and that has been fixed--even after reinstalling all Addon's I can still read articles. I log into my Fox account and the webpage reflects that but when I try to post a comment it says I must sign in to post, yet I am signed in! However, I go ahead and follow the links to sign in (check e-mail/click sign in to Fox etc.), ultimately it tells me I'm now signed in. But when I go back to the comment section it still says I must sign in to post but I am signed in. Besides removing Addon's I also tried removing the FF browser (Win 10 recommended a refresh instead of uninstall so I did that). No help, I'm thinking whatever is causing the conflict when refreshing FF the sync simply puts the conflict back! I'm still requested to sign in when I am signed in! As stated earlier my Fox account in MS Edge works fine.

I am trying to access my account on https://web.reflection.app/. The dashboard page partially loads, with other areas showing a spinning circle. Another page has the same issue, with most of the content not loading at all. See the attached screenshots. The website works fine in Chrome and Edge (which I know is also Chromium-based); and I have the same extensions in all three browsers. The website was reportedly built using Flutter.

I've added the website to the exceptions for cookies, tracking protection, and pop-ups. I've also tried refreshing Firefox, using a private window with no extensions, and creating a new profile with completely default settings. I've also tried the troubleshooting steps mentioned at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can and https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors.

I would appreciate any suggestions!

Thank you. Peter

Windows 10 Pro v 22H2 Firefox 121.0.1 (64-bit)

I have tried preventing Firefox from autostarting with Windows start up by examining these potential program starting locations:

Firefox-Settings-General: "Open Firefox automatically when your computer starts up": Option not available about:config - toolkit.winRegisterApplicationRestart - set to "false" No listing for Mozilla or Firefox in Windows 10 "Startup Apps" settings page No listing for Mozilla or Firefox in Windows 10 msconfig.exe/System Configuration-Startup No listing for Firefox in Windows 10 Task Scheduler No Firefox program in Windows 10 - %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder All Firefox extensions (2) are disabled

Where else should I be looking? Thank you

I have noticed that my browser saves certain data that was filled into forms on websites such as contact info, or 2FA codes. Of course, the all options for Logins and Passwords as well as Forms and Autofill are turned off. So I wonder, what causes this behavior? I would maybe think these are some cookies, but after clearing them and deleting all site data this still happens. For 2FA codes this is harmless. but I'm concerned Firefox may do this for passwords too. Anyway, why would I need to save info of TOTP?

Note: Example is for SimpleLogin.

I just upgrade my firefox, but it did not import my history, cookies, bookmarks or passwords. I found a backup of the bookmarks (in a bookmarkbackups folder) but how do I restore the everything else?

Whenever I go to a Google page (tested on Google.com Docs, Sheets, Forms) the page crashes. The issue started sometime around this afternoon.
