I'm unable to install a dictionary from the official FF add-on store. I click on "Install" and this button sort of "activates", turning grey, but remains stuck forever. It's not an add-on, it's a language extension. I read the troubleshooting article. I did NOT clean the extension folder together with sqlite, ini and JSON as suggested, as I'm not sure it relates to my problem.

FF 142, macOS. Installing dictionaries worked in 141, 140 and earlier.

Within a minute of starting Firefox up, it loses internet connection and prevents the computer from connecting to anything else. Using Ethernet or Wifi doesn't work. The only thing that corrects it is restarting the computer. List of things we have tried: Troubleshooting Mode in Firefox Removing all addons Uninstalling and Reinstalling Firefox with the latest update Disabling DNS over HTTPS Clearing Firefox's DNS cache Clearing the computer's DNS cache Adding IPv6 to our standard IPv4 connection Rebooting the router Used a new Firefox profile Run a virus scan

This is on Windows 11. There are multiple other computers on the network, with W10 and W11, and none of them are having this issue. I've tried everything I can think of. After losing connection, it still pings 8.8.8.8.. Is there anything else we can try?

hello https://qrsj-map.lzhailalu.com/ black screen https://www.1024tera.com/ white screen, not loading

tested on Firefox 141.0.3, 142.0.1 and nightly 144 new profile, default settings, no addons, normal and private mode

Brave 1.77 working in both normal and private mode

the problem caused by certificate & certificate give cors error

1st website asked to trust certificate, after i did website loaded with black screen cuz cors blocked resources from loading, the certificate didnt carry over to sub domain https://n-cdn.lzhailalu.com/snow4/2/2/1.webp if i click this i get Warning: Potential Security Risk Ahead to trust same certificate this website was lacking r10 lets trust certificate, if im not mistaken it should be replaced with ISRG Root X1 & ISRG Root X2

2nd website certificate was auto verified but cors kicked in blocking resources like this one https://s3.teraboxcdn.com/fe-static/fe-v5-web-index/js/index.b81a2a8e.js clicking this give Warning: Potential Security Risk Ahead to trust digicert check my screenshots

i tested some cors addons on other profiles but couldnt bypass it

we need a fix, this is just 2 examples, theres many websites that certificate and cors ruin them, ppl test their websites on chrome thats why firefox need workaround for certificate and cors to work like chrome.

please dont tell me it simple just trust certificates cuz i figured out the problem, that not a solution, brave worked out the box, so thats mean for every website i visit i need to ckeck console for errors

and not switching firefox to brave or chrome, i only use them when firefox fail me in media or websites give me errors, i used firefox for so long and im not going to switch

if theres no proper fix, i need a way to disable certificate, cors or both permanent even if i have to edit omnija, just show me the way, please

for some weeks now, Firefox (latest, in Windows) crashes, or says 'not closed properly' and shows (usually) 12 'instances' in Task Manager when only one tab has been opened. I'm not techie, and need clear advice. Can anyone help please? Hugh, UK

I prefer all my login accounts to log out when I close Firefox. All of my settings are set up to do so, nothing changed, yet suddenly for the last week or so, it has simply stopped logging me out. Every day when I log in, there everything is again. I keep rechecking all my settings, even turning them back off and on, and nothing is fixing this. What's going on?

I asked this same question in Reddit and got a reply to uncheck "delete cookies and site data when Firefox is closed", close all Firefox windows, and reopen them, and this did not correct the problem. Please advise.

I saw bunch of threads which suggest to enable "ctrl+tab cycles through tabs in recently used order". It does what I need, but in previous versions I used to press only ctrl+tab. While I was holding ctrl I could iterate over tabs via tab key. After releasing ctrl selected tab was chosen

It differs with current behavior where you press ctrl+tab and after releasing all keys pop up with tabs is still be viewed and you need manual action with space/enter/mouse click to open selected tab

Is there any way to use only ctrl+tab without any manual actions required like it was back in the days where after releasing the control key selected tab is opened?

I am suddenly unable to login to my iCloud account using Mozilla Firefox. I was always able to do so before now. I am able to login using Microsoft Edge browser. I have disabled the Firefox pop-up blocker but still not working. When I input my username and password, iCloud sends me an authentication code... but that next pop-up screen from iCloud having a place to input the code does NOT pop-up, so I cannot enter the code. That pop-up screen comes up in MS Edge. Any help is appreciated!! I'm running Windows 10

I have to resort to using Chrome (yuck) when using Fedex.com. Please fix issues with Firefox and Fedex.com (very, very slow loading) thank you

I've tried to install the language pack for english to have swedish and english spelling checked on my computer. I've added it like the discription mentions but it doesn't show as an option when I try to change it.

I have forgotten my Primary Password for Firefox on my PC.

I found the solution to reset it at: https://support.mozilla.org/en-US/kb/reset-your-primary-password-if-youve-forgotten-it It explains that the stored data will be lost, which is fine. I made a recent backup (~99%).

But it does not say what will happen to connected devices (phone) using sync on the same account.

Will the emptied local storage on PC repopulate the data from the phone? Or will the phone sync with the empty storage on the PAC with as a result an empty storage on the phone as well.

I've been a very long time Firefox user, and have for many years been aghast at how prominently Firefox promotes a virulently antisemitic paper called "The Guardian" on its recommended stories. Every time I see it, I thumbs it down, and have been doing so for years, hoping that eventually the algorithm would stop recommending that junk to me. I have NEVER clicked a link to "The Guardian" from the recommended stories page either, not even once. I'll often see 2-3 links from this virulently antisemitic paper and thumb each one down. Why does the algorithm keep recommending it to me? I know that I can turn off Recommended stories, however I like the content, and have found a lot of interesting stuff through it. Why is Firefox relentlessly pushing Nazis propaganda?

(If you don't think The Guardian pushes virulently antisemitic Nazi propaganda, I would be happy to share links demonstrating how it does exactly that, but since this is a new account, I don't want the algorithm to think I'm spamming.)

How can I customize recommended stories so that only articles that require a sign-in to be viewed not be shown to me. If I see a story title that looks interesting and I select it and a sign in page immediately pops up (all of which I do not wish to sign up for just to read a short article) then it feels like another privacy grab.
