Firefox supportforum

For the past few weeks, Firefox has started crashing when logging into various websites. I've updated Firefox, cleared cookies etc, reinstalled Firefox, opened it in Troubleshooting mode, updated my OS, disabled extensions... everything I can think of. After some sleuthing, it seems to only happen when trying to log into a website. Doesn't happen on every site, which is weird.

This is so frustrating, please help!

I can load their main page but I cannot log in. I get the error I have attached. Finally, I had to log in from Safari after a lot of hassle and help from a customer service rep. What happened? I have been logging in here for years from Firefox. I am not having this issue with any other site.

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

Firefox stopped working with my VPN on when I updated my OS to Sonoma, yesterday. I use PIA for my VPN.

I have done the following, so far, restarting my system several times between trying these things:

Checked that internet connection and modem are fine. All pages load in Safari, with VPN running, but I prefer Firefox.

Checked the Network settings for my Mac. Ensured that No Proxy was selected.

Cleared my Firefox cookies, cache and history.

Tried running in troubleshooting mode, turning off all extensions.

Tried turning off Advanced Tracking Protection, which I usually run on Custom.

Refreshed Firefox.

Finally, I turned off my VPN and, viola, all sites work. Turned it back on, and can’t navigate, again. For instance, I tried to open YouTube, and got a blank screen. Turned off VPN, and got to main YouTube page. Turned the VPN on and tried to log in…nope. Turned it off and logged in. Turned it back on and tried to open a video….nope. Turned it off and opened the video…etc., etc..

I very much wish to continue using both Firefox and my VPN. Can you suggest a course of action? Thank you for any advice you can give!!

Is there a way to always show the tab close button on the tabs? Or perhaps to show the button on hover of the tab? Chrome does this and I find that very helpful, in cases where I want to close a tab and do not want to re-open that page.

Some context: When you have many tabs open (I know, who does that?) and you want to close some of them, but do not want to select those tabs, currently you can right-click and scroll through the menu to the `Close Tab` option. This is slow and a bit clunky. The `Close Tab` menu option is buried in the bottom-middle of the list.

This issue is somewhat complicated by the fact that I use the excellent Auto-Tab Discard extension to discard/sleep tabs. (https://addons.mozilla.org/en-US/firefox/addon/auto-tab-discard/) So when a tab is discarded, and you click on it, the tab reloads. Which is silly when you just want to close it.

Anyone aware of a way to always show the close-tab button, or show on hover?

Thanks!

Hello, i've updated the Firefox browser to version 120 and since then polish texts in browser are broken. How can i fix it or restore to previous working browser version?

Hello!

I always use private browsing so I thought that my history was totally not being saved, but discovered recently that when I started to type within the search field, that many of my past searches were listed in the search field with the type highlighted in purple. I had to manually go in and delete all of these past searches. I don't want any search history to be saved. Is there a setting in preferences that I'm somehow missing? Why is Firefox saving these past searches if I have it set to Always Use Private Browsing?

Thank you!

I am using Firefox Developer Edition in a work environment that only saves directories between weekly restarts by explicitly managed rules. As a result of some missing folders from my weekly restarts, I need to sign in to my Firefox account and enable sync each week. Currently my machine retains the %APPDATA%/Mozilla and %LOCALAPPDATA%/Mozilla directories + children.

What other directories are needed by Firefox Developer Edition in Windows to retain the user profile/syncing, et. al.?

Thank you for your time!

Today, I noticed that fonts on sites look different than normal. At first I noticed that font looked smaller, but zoom is set to actual size. Then I noticed that while on a site with a black background the text was displaying as black also, making it impossible to read. I looked through the preferences and everything pertaining to fonts and colors appears to still be set to default. Next thing I tried was opening the same site in private window. While in the private window, the font and color appears as it should.

Any ideas how to fix this?

I'm not very computer savvy but I followed a website a few months ago to edit Firefox so it'd default to dark mode. I think I went in and edited source code? I can't find the instructions anymore but I'd like to revert back to the original setting. How do I do that? I tried to refresh Firefox but it's still coming back with some websites in dark mode and some not. Please advise!

As of today, I'm seeing black text on the black background of every site with a dark theme, including Google Search and Github

I'm running Firefox Developer Edition 105.0b8 on macOS 12.5.1. My macOS Appearance is set to Dark

Switching the Website Appearance config setting between Firefox Theme, System Theme, Dark, or even Light does not change the colour of the text

Hi everyone,

Last Saturday, I was able to sign in to Firefox Add-Ons Firefox Add-Ons and submit a pre-release of an add-on I'm working on. But today, I'm being forced to enable 2FA to simply log in to the site. I don't want to enable 2FA, I just don't need it. Can someone explain me why is this happening ? Can I just log in and submit my add-on's update ?

I've tried to sign in two different MacBooks (M1 12.1 and Yosemite 10.10.5), using two different Firefox versions (99.0.1 and 78.15.0esr). Also, I haven't enabled 2FA in my personal account.

Thanks in advance.

Hi,

After updating Firefox to 116.0.1 my tabs keep randomly crashing. I get some crash reports *occasionally* - meaning not all crashes produce a crash report - but I'm not sure what to do with them, they seem inconclusive. The last report (not for the last crash, though, which didn't produce any report) is bp-3334b934-58b5-4226-887a-235300231117

Hello, I am a user on Mac! I am having an issue with moving tabs fluidly. Yes, moving tabs inside the window is easy but when I move them outside the window, it makes me a little uncomfortable. In the images and video I have sent, you can see that an unnecessary thumbnail of the tab pops up even when I move the tabs inside the window. This makes it harder to know if I am even moving the tab in the first place. Then it takes like 2-5 seconds for the new window of the individual tab I moved to appear. If whatever I said is quite confusing which I apologize for, I would very much recommend taking a look at Google Chrome, the browser I don't prefer, however, try moving the tabs around and outside one window and creating more windows with individual tabs. It feels more fluid or swift and easy to handle. Compare that to Firefox and a big difference is to be seen. I am concerned about this issue really because I am replacing my previous browsers, not only Google Chrome but browsers like Edge too which are capable of not having that issue, with Firefox instead and hopefully Firefox can have this capability. I also multitask a lot so I usually encounter this problem on Firefox. I hope this is fixed and am sure it will help a lot of users! Thank you! Here is a YouTube video link for to provide a further understanding of the issue: https://youtu.be/jRuBDH32hPI

For the last couple of weeks, whenever I access the finance.yahoo.com/ website, my computer slows to a crawl. I run Activity Monitor to show me FF memory usage has surged to 6.5 GB! I cannot just 'quit' FF, have to force quit to regain the memory. No problems with any other website. I am running Mac OS 12.7, 8GB RAM, FF 102.0.1

Any help/suggestions appreciated.

I told Firefox to never remember a website login user/pass but now want to revert this. I have looked for this option but can only find the remembered user/pass. There is an option at the bottom of the chrome password list, but not in firefox.

Can someone please point me to the area that i can remove this "never remember logins for this site"

Thanks in advance

Google Calendar and a few other websites do not render symbols correctly. Please see attached. What should be displayed instead of letters are symbols such as > or ^. I've tried updating FF (103.0.2), ran in Safe Mode, disabled extensions, and nothing has helped. I'd like to keep using FF instead of Safari (running MacOS Monterey 12.5.1), but this is annoying.

Any ideas?
