Diễn đàn hỗ trợ Firefox

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.

Is it possible to access Settings>Accessibility>WebsiteContrast to quickly turn it on and off, by setting it as a bookmark (or quick access) rather than having to click settings and search for it each time?

Can you let me know if this is possible, or possibly add it in a future update if it is not?

I know that there are extensions that allow you to do this, but I am wary of using too many extensions because they can be a privacy vulnerability.

I noticed that the World Clock widget includes Pakistan Standard Time (PKT) but does not provide an option for Indian Standard Time (IST). This is surprising given that India has one of the world's largest internet user bases and a significantly larger population than many countries currently represented.

India operates on a unique UTC+5:30 time zone used by over 1.4 billion people, making it one of the most widely used time zones globally. The absence of IST while neighbouring time zones are available feels like a major oversight and reduces the usefulness of the widget for Indian users and anyone who regularly works with Indian colleagues, clients, friends, or family.

Please add Indian Standard Time (IST) to the World Clock widget as a standard option. Its inclusion would greatly improve the widgets global coverage and usability.

I cannot connect with my on-line banking site. When I try, I get the message "Bad Request--Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. I am able to access the site using another browser, so there cannot be a problem with the site itself. This situation has only existed since Firefox did an update. So, the problem must lie with Firefox. If it is not fixed, then I fear that I will have to discontinue using Firefox as my online browser. Please have someone from technical support contact me. [edited email from community support forum]

I'm trying to add the Dashlane extension to my laptop running Windows 10 or 11, and Firefox. But I cannot do this as my computer is in safe mode (troubleshoot mode?) How do I get out of this mode so I can add Dashlane extension. Thanks for your help;. Jonnie

'I am posting this for a third time, because I am absolutely sure it is caused by the latest Firefox update.

I am typing this into Notepad and copy/pasting it to the text box on the site.

I am legally blind, and I am very dependant on the Windows Magnifier. Yesterday I took the latest Firefox update and after installing it, the Windows Magnifier will no longer follow the text cursor on web pages rendered in Firefox. It will follow typing in the address bar and the search bar on the task bar, but it will not on web pages rendered in Firefox.

I do not have this problem with Chrome or Librewolf.

I had made two earlier posts with no response from Support. I have been trying desperately to figure out what waws going on as I was moving links, bookmarks & passwords into Librewolf.

I tried to refresh Firefox. It didn't work. I tried safe mode. It didn't work. I even tried a different profile. It didn't work. I even tired uninstall & reinstall Firefox. It didn't work.

I even called the Microsoft Disability desk and had them check my magnifier settings, and they are fine, and yet even if I toggled them on & of--it still didn't work.

So finally, out of desperation, I did the dreaded System Restore.

I rolled it back to August 18th and sat and waited.

And though I had to relog into Firefox--it worked!

and i have been surfing happily all evening until I loaded the Spotify player page and it wouldn't play. Okay this was weird because I had been using it all week and suddenly it wouldn't play. I did a search, and apparently it wasn't just me. I opened the About Firefox and there it was--the dreaded update.

Believe me, I really didn't want to restaret the browser, but it was doomed to happen anyway.

And guess what--the Windows Magnifier view won't follow the text cursor in web pages rendered in Firefox--Again!

The Spotify player plays again but.....

If you don't believe me, open the Windows Magnifier, dock it on your task bar, and try to type into a web page. The view just goes cockeyed.

So yes, the update has a bug. And for all the people who are visually handicapped and use the Windows Magnifier we are cursing you right now and hoping for a quick fix before we all have to move to Chrome.

You sighted people have no idea how frustrating this is.

At least I'm glad it's not my PC.

But if it doesn't get fixed, I"m absolutely done with this browser. It is now unusable for people with visual disabilities.

Good luck.

Thank you. '

Hi, I was asked if I could contact you by google disability.

I'm having a huge problem creating a channel on youtube with a live.co.uk account when using NVDA.

I press b until I hear account menu button button submenu, pres enter or space, then arrow down to create channel and press enter. Nothing seams to happen.

Google disability has shown me a couple of video or audio files proving that it can be done, they've even said that they tried creating an account with an outlook account, what live.co.uk is called now from my understanding.

SO I'm really confused as to why they can do it and I can't.

I can't show you with OBS because it messes with my screen readers speech so if you have another way I can show you; please let me know.

I've already tried the following, suggested by disability support: 1. uninstalling and reinstalling firefox.

2. making sure addons are disabled, the only one I left enabled was a volume booster but I doubt that would be the issue.

3. Setting NVDA back to factory settings and disabling all addons.

This has been confusing me on and off for up to a year now.

F12 opens the inspector - How to change th eshortcut of remove it completely

F12 is near the backspace key on my asus laptop and I keep accidently hitting it and would like to remove this fuctionality. I can just use ctrl shift c if I need it

My sanity is at stake here!

Now that my browser is Firefox I cannot get to my email or anything else on my computer. What must I do??? At one point I was signing in to Mozilla Firefox and it said that account already exists. This is very frustrating for an older geriatric. Please send me instructions to get back where I was. My present email address is [edited from public] @gmail.com.

Back in the days it was always possible to change Proxy port number (or, I believe, any other numeric value) by moving the mouse scrolling wheel when the cursor is placed inside the related field. I don't know whose intelligent decision it was to disable this functionality, but it has gone since the last update (v130.0). Now the window scrolls regardless of the cursor position. It looks like it works fine, but for those who are used to this kind of functionality, it turns out to be inconvenient.

Please, roll this back before it's too late :) Thank you.
