Firefox Community Forum

I'm receiving two Ten Tabs to my single email address. If I unsubscribe from one it will also unsubscribe the other since both are sent to the one email. One email sender is firefox_at_mail_mozilla_org_[alpha numeric omitted}@privaterelay.appleid.com, the other sender is firefox@mail.mozilla.org. Is the easiest solution to unsubscribe and then resubcribe?

I am running Firefox version 153.0.1 on a 64bit install of Windows 11.

A few days ago I had to factory reset my computer, including a clean Windows install. Since then, when attempting to access https://vodafone.cz/muj/prihlaseni, I get an Imperva Error 15 "Access Denied" error screen - screenshot attached here. Clicking the Imperva logo on the bottom of the error message leads to https://www.imperva.com/why-am-i-seeing-this-page/?src=23.

I was able to access the site in the past, most recently on July 8, 2026 - this would have been Firefox version 152.0.5.

This error persists in troubleshooting mode but not in private/anonymous (with or without extensions enabled), nor does it appear in Microsoft Edge or Firefox on Adroid.

Clearing cookies and cache did not help - in fact the error first showed up on a clean install of Firefox, when there weren't any cookies or cache stored yet. I've tried different DNS over HTTPS settings and listing the site as an exception in settings, but none of this made a difference. Enabling Firefox's built in VPN also made no difference, regardless of the selected location.

I found a recent post (https://support.mozilla.org/en-US/questions/1588627) describing a similar issue on a different website and tried the suggestion listed there to try a fresh profile - this seemed to work, but within a couple of minutes of browsing the error message returned. I've even reinstalled Firefox entirely, but this too did not help for long.

Interestingly enough, the error message lists a proxy IP address (not blacked out on the screenshot) despite the fact that I am not using a proxy.

The website provider's tech support claims this is an issue on the user side, not theirs - they have not been able to replicate the issue.

Is there anything I'm missing that would explain why this is happening?

Thanks!

Firstly I have lost my default,. I had it set up as google . next I lost all my bookmarks, I have also lost the bar I had which included bookmarks history etc. this all happened in the middle of using a program and now I cannot get it back. PLEASE TELL ME WHAT IS HAPPENING

I love vertical the tab view. Unfortunately, on one of my systems, vertical tabs to not render correctly. Groups are shown, but there are no favicons or titles shown (see attached image). The tabs are also not clickable. Any insight into how I could debug that would be amazing!

I'm running the latest version of Firefox on the latest version of Windows 11, and I'm trying to watch TV shows on PBS's Passport service. I get the video but not the sound. It's been like this since Saturday. I don't have this problem at all with Chrome or Edge. Is anyone else having this problem? JT

I cannot get into my Paypal account because Mozilla Firefox is asking me to set up a passkey. I press Continue and it tells me to enter a PIN. I don't have a PIN set up that I know of. If I try one, it is wrong and says I have tried too many times. When I go to the Settings where I should set something up with Window Hello, it says it is not available. I just want to log into my Paypal account like I used to. How can I bypass all this stuff?

Every time I select Gmail on Firefox page, it requires me to sign in with a code. I have selected 'Strict' for browser privacy and 'Clear history after closing Firefox'... plus a number of other settings. I then get a notice of someone signing into my account each time, as does the person who I use as a backup to my account. I'd like not to go through that each time I access my Gmail account.

Thanks for the help.

I have albinism. Pure white backgrounds are not an annoyance – they cause physical eye pain and trigger migraines. Every time I visit support.mozilla.org or accounts.firefox.com, I am forced to endure #FFFFFF with no way to change it.

To anyone about to defend Mozilla blindly: this is about accessibility and eye pain, not brand loyalty, so do not silence me.

What Mozilla has done:

• Disabled extensions (Dark Reader, Stylus, Dark Mode) from modifying these pages – they are explicitly blocked by Mozilla's own Content Security Policy.
• Removed ui.systemUsesDarkTheme and layout.css.prefers-color-scheme.content-override from having any effect on these sites – they ignore prefers-color-scheme entirely.
• Left no about:config toggle to disable the forced light theme.

The only remaining workaround is a userContent.css hack with filter: invert(1) – which requires a visually impaired user to manually edit CSS files and restart the browser. That is not accessibility – that is hostility.

Security excuse – debunked:

• "We block extensions for security" – extensions are sandboxed. Blocking them on your own support pages is a deliberate policy choice, not a technical necessity.
• "We want a consistent brand appearance" – branding does not override accessibility. Forcing #FFFFFF on users with light sensitivity is a violation of basic inclusive design.
• "We respect prefers-color-scheme" – you do not. These two domains explicitly override it.
• "Users can just use Dark Reader" – you block it.

What I demand:

Make support.mozilla.org and accounts.firefox.com respect the system prefers-color-scheme media query. If you insist on light branding, add an official dark toggle in the site header – stored in a cookie or account preference. Stop blocking extensions from applying user‑chosen themes to your own sites. That is not security; it is control. You are a non‑profit that claims to value accessibility and user control. Your actions say otherwise. Fix these two domains. No CSS hacking should be required for basic vision safety.

I've searched the community for support to add bookmarks inside my PDF files using Firefox, but all I get are articles and community posts from two or three years ago.

I currently see no features or buttons to edit the outline of a PDF using Firefox (153.0.4). Are there any Firefox extensions or other Firefox methods that I can use to do this in the meanwhile, or do I have to resort to using third-party software and solutions?

Where can I suggest to add this feature if it doesn't exist?

Thank you for reading.

After the latest Firefox update, I'm unable to connect to my router's IP address, 192.168.1.254. Other IPs on my system are fine, it's just that one which won't work. Nothing appears on the page, it's just blank and the little dot to the left of the tab never stops jiggling left and right. All that said, I can connect to the address using Chrome. I thought of checking the "Don't use HTTPS-only" setting but the settings menu has been changed and that particular option has disappeared. Any ideas?

Please help to Dismiss the 'Stuck" Amazon icon on the main search page!

I can't dismiss it !

Please see the yellow highlighted circle with an arrow pointing to the Amazon icon.

Thanks!!

recently i've created a html backup file in zen browser. and when i choose it in the settings menu on another device it says "This file isn’t working. Try picking a different file."

Здравствуйте. Я установил сертификаты по инструкции, которая лежит на s.sber.ru/70VQ2B . После этого в мозилле не прогружается полностью окно входа на online.sberbank.ru, не видно содержимого фреймов (сейчас попробую сделать скриншот). В Microsoft Edge работа нормальная. Удаление сертификатов, перезапуск браузера и компьютера не помогли. На других компьютерах ещё не проверял. Посоветуйте, пожалуйста, что можно сделать. Windows 10, Firefox 153.0.3 (64-разрядный).
