Firefox Community Forum

Dear Sir, I am trying to set up firefox browser.I have received a notice 'your new profile is good to go' I cannot see what I should do next.Please advise. Many thanks Roger Dace

I am a big fan of the new VPN feature that you guys introduced that is strictly for browser. There are only two current issues i have with them and its the limited bandwidth of 50 GB that is very low and i would like the option to pay a reasonable price for unlimited. Also when i disable the vpn for a website there is a blue pop up in the corner every time i tab over or open the specific page on a new tab that i can't disable or change the behavior in any manner.

I was on a website for Met Opera, buying tickets and suddenly a widget appeared on the lower left corner that says: Opt-Out Signal Honored. Not only did I Opt Out, but I no longer can navigate the website, and there is no visible way to cancel this. Please help. It does not appeaer on other web pages, or other browsers. What is this? I've tried locating it in settings, and settings does not have that privacy option checked. How can I remove it? thank you, Anne Marie Mascia

When I enable the firefox built-in vpn I have an error: "The proxy server is not found

Firefox cannot connect to the server at accounts.firefox.com What can you do?

Try to connect to another device. Check your modem or router. Log out and reconnect to Wi-Fi."

Thanks.

for context: my laptop was working/running completely fine last night, as of about midnight (east coast). booted it up around noon today to see that it was super slow and kinda laggy (this is a windows problem, not a firefox one, don't try and fix that, i know it sucks), and that if i restarted/shut down, it would automatically update (not what i wanted). when i did finally begrudgingly restart my laptop, it auto-updated as windows does, and i expected to open up firefox and go on with my day.

unfortunately, it prompted me to make a new user. and when i signed into my firefox account, it treated the browser that i have used for at least 8 months like i had freshly downloaded it. all of my history on here is gone. all of my bookmarks are gone. when i connected my phone to try and sync from what i had left before i updated, all my sync information went down the drain and is completely gone as well. i really don't understand what went wrong here, and i'm honestly devastated that all of my work and my history has to be painstakingly rebuilt.

if anyone has any idea of what happened here, it'd make me feel a little better and try to avoid it in the future.

So, today I found that absolutely all of my tab groups have been wiped from existence. Not passwords, bookmarks, history, extensions or anything of the sort. Just tab groups specifically. Everything else in my profile is still here. I tried restoring from a backup using the Session History Scrounger at https://www.jeffersonscher.com/ffu/scrounger.html but my closest backup was a March 26th one that is missing an entire tab group created after that date.

I tried searching other solutions to my issue, but nothing has worked so far. It doesn't have anything to do with updates as the last one happened on March 26th and I definitely used the tab groups after that point. I'm at a complete loss on what I am supposed to do, as I lost ~600 tabs combined across all groups

Hello, I'm French and I'm not very good at English I’ve been a Mozilla user for many years and am very satisfied with it. I’m having trouble interacting with the Ohm Energie website. I wanted to sign up for an electricity plan. The Ohm Energie page opened fine in my browser, but as soon as I tried to interact with it—for example, to request a quote—I received the following security notification: “Firefox has detected a potentially serious security issue with espace-client.ohm-energie.com. Someone impersonating the site might try to steal things like credit card information, passwords, or email addresses.” I was forced to use Chrome to sign up for my plan. I’m not the only Firefox user facing this issue. I called Ohm Energie and was told that many other customers have also encountered this problem. I’d like to be able to access my Ohm Energie account via Firefox—what can I do? I should mention that I’m not very experienced in resolving this type of issue. Thank you for your help

When I have set the size of the window and then move the window to the left or right then the application automatically expands the window. I do not want it to do that as I want to be able to have the firefox window where I choose and the size I have chosen, but the program automatically expands the widow to fill the screen.

This has worked fine in the past, and works now in Chrome, but not Firefox. URL is https://outlook.cloud.microsoft/mail/?bO=1&msalAuthRedirect=true&sessionId=20fbbbb0-2fa6-4848-8fec-c20c6d3a8be4

La version initiale présentait une page d'accueil personnelle.

La nouvelle (depuis quelque temps) chamboule tout.

Comment faire pour la retrouver et la figer ?

Merci.

Google seems to be slowing down my PC. So I deleted google and installed Mozilla. I set Mozilla as my default browser but google is still there. How do I get rid of google?

On entering a search into the search box on firefox home screen with google selected the resulting display is just computer code (looks like this: (�/�Xx<�l�/�F$�O�6
g�W��wd) selecting a different search engine or going to google.com works just fine. How do I fix this?

Mostly experienced on Reddit so far.

When visiting a previously visited subreddit. The page loads part way down instead of at the top.

This seems to have been introduced with v149 on Windows 11.

I'm getting totally disgusted with Firefox, Windows 11. FF updates automatically. More and more websites will not open when I'm using the browser, and they open just fine when I switch to another. Since I have used Firefox ever since its inception, it's extremely distressing. It doesn't matter if I turn off ad blocking and tracking software. The latest site that won't open is Substack, which works perfectly okay using the Brave browser. This is probably the 10 instance this month of a website that does not work with FF, including once that always did work just fine.

Other changes are also annoying, but I'll save them for another complaint.

I have google as my default search engine and having the search engine shortcut suggestion gets in the way of my work flow. When I open a new tab, I'd like to just press the tab button once to move to the search bar. Any way to accomplish this in about:config?

When Firefox opened a couple of days ago ago the layout changed without my doing anything. I have a approximate 3/4 inch gap that wasn't there before. Can't figure out how to get it back the way it was before. Thank You
