Firefox Community Forum

Hi, I am using Firefox For a few years, but for last 1 year my workload is high and I usually need to open several tabs. After I keep tabs open for a while, firefox becomes slow. Closing a few tabs help but I want to know what is causing it. IS there a way to check which tab or extension is causing it? I am using latest firefox on windows 11.

Recently I cannot use Paypal to process any online payment on Firefox without the browser crashing.

OS: Windows 11 25H2 Reproduction steps: a vendor would have a Paypal button. I would click on it and Firefox would open a pop-up window briefly before crashing.

The pop-up window is normal behaviour for how Paypal processing has worked on Firefox in the past. I have tried turning off potential content blockers: 3rd-party userscripts loading through ViolentMonkey, content blockers via AdNaseaum, and Enhanced Tracking Protection to no effect.

Los videos de YouTube no se reproducen correctamente en Firefox. Algunos videos no cargan o se quedan congelados y no puedo verlos normalmente. Ya intenté actualizar la página, pero el problema continúa. Quisiera saber cómo puedo solucionarlo.

Had my laptop serviced at Best Buy, but upon booting it up the icon for 1Password in the upper tool bar was missing. Trying to figure out how to add it back. I use Mozilla Firefox and have Windows 11.

I routinely check out several local news outlets' websites and for the last 2-3 weeks, since a Firefox update (using FF 156.0.1 (64-bit) on Win11, v25H2, Build 26200.9550) I keep getting a Norton popup box saying "we prevented your connection to <x> because it is a malicious website", where 'X' is either littlestastronaut.com, or something like planted.com (screenshots of Norton popup windows doesn't work). This doesn't happen with any of the other couple dozen websites I visit, just 2 out of the maybe 5 or 6 different news websites I look at. Odd thing is I look up either of these two 'dangerous' websites and they either don't exist or they are some school related website. That popup comes after I have to select either "continue without ads" or go to the FF address bar and disable the ad-blocking for that site, so I'm thinking that there's maybe something in FF that is causing this? It happens on both of these sites whether I check "continue without ads" or disable the FF ad-blocker which doesn't make sense that that 'malicious site' is contained within an ad on the news site because on one I don't disable ads so it shouldn't even come through but still Norton catches it??? Yes, A-I will one day rule the world....ya-right.

Iam getting statements saying someone living in same town as I getting on my account with a Linux or android what is Linux representing and when they say android with one ?? I have 3 different thing's i use but I never use a computer. Lap top or desk type???.

you are blocking "entry.ostralia.cc" saying the ssl is expired....

BUT SSLCHECKER link text shows it's OK ! and all other browsers allow it...

you could at least allow me to access it under the 'advanced' option like in earlier days...

( the Host provider has mixed up billing for the 3 SSLs on my site , but all 3 are active and valid SSLs...)

The British have colonized my spell check somehow and I'm completely at a loss on how to evict them.

When I right-click to change my spell check language, the only option I have is "English (United Kingdom)", while the only Dictionary that I have installed is "English (US)". In my language settings, while I can set any preferred language, my only Fallback Language option is "English (GB)".

I would like my Spell Check to properly reflect the dumb language that I speak, please. I'm on Version 156, but this has persisted for several months.

Steps already taken: - Scoured the settings for a misconfiguration - Rebooted my computer - Cleared the Startup Cache - Opened Firefox in Troubleshooting Mode - Refreshing Firefox

I made 2 copies of the Firefox backup folder on a Win 10 computer and haven't been able to restore either to a Win11 computer. The error message is "This file isn’t working. Try picking a different file." The Win 10 computer had a later version of Firefox than is on the Win 11 computer but was not the most recent version available.

Any ideas for installing the backup file or for a work around so I have my most recent profile data, bookmarks and passwords on the Win 11 computer?

Hi,

I'm autistic and I find the new design updates really, really disturbing and I need to change it back to the old design.

I read on the help article for reverting to older versions that it'd be better to ask if there's a workaround instead of downgrading because of the security issues, so yeah does anyone know how to revert to the previous Firefox design and maintain the current version of the browser?

By the new design, I mean the roundness of everything and the teardrop shapes for whatever's left.

I'm still gonna revert back for now but hopefully there's a fix I can use.

I received an email stating the following: "Firefox now has a built-in ad blocker.... Turn it on under Settings > Browsing." There is no "Browsing" in my Settings.
