Firefox Support Forum

Hi,

On what port does the firefox extension update on does it use port 21? I need the extensions to be auto updating like set and forget knowing that my firewall is not blocking the required port

Thanks

In troubleshooting another issue, I discovered that running Firefox without hardware acceleration occasionally results in very weird text corruption and video stuttering. I was able to capture some screenshots of the issue, which I have attached. The text is still selectable and copy/pasting it to a document will show the proper text. Closing PIP windows helps the stuttering a bit. Issue persisted when a single tab of Firefox was the only non-background program running.

I have turned hardware accel. back on and haven't experienced the issue since. Just thought I ought to post in case someone else had this issue too.

Having issues with Firefox chugging too much memory, I have 32GB of RAM and in Taskmanager, memory usage can get up to 60% having Firefox open, this is also becoming an issue while trying to use other software or playing games as I get errors that there isn't enough memory when Firefox is running.

I run Window 10 and love session restore in Firefox, as I usually like about 15 of my usual tabs open each session. Though Firefox restores these tabs successfully, it often also restores long-closed tabs that were no longer open during my previous session, sometimes resulting in my having over a hundred tabs open which I have to manually close. How do I stop Firefox from 'restoring' tabs that were no longer open when I last powered-down my computer?

I am visiting mymother who likes to eat in a local supermarket where they have a cafe. I paid for our meal using cash and I did not use the in store wifi and did not interact with any in store services.

I get back to my mothers apartment and open firefox to do some browsing, the first thing I see is a sponsored ad for the supermarket I have just been in.

So two questions, I understand that my phone number can become visible if I interact with a local service. But no interaction took place but they still worked out who I am and where I was. How was this done?

Secondly some financial interaction has presumably taken place between firefox and whoever controls the advertising for the supermarket. So they put out some kind of call to say "this guy has just been in our supermarket and we want to hit him with some linked content" and firefox have put up there hand and said "yep we got him right here, you pay us x and we will stick a link on his opening page"

So how does that work with firefox? so they say thay are a privacy web brower but they appear to have just sold me off to a supermarket?

I like when I open a bookmark, that I am not forced to view it right away. This can be VERY annoying when opening multiple bookmarks but I want to stay on my current one without having to switch back to the one I was using. I would like an option added at least to have bookmarks in that automatically switch to when opening. Please.

Well done Firefox team.

I got a notification this morning telling me I could update Firefox to the latest version and I had nothing urgent so I did.

Imagine my suprise when all my bookmarks, my passwords and logins appeared to have disappeared. Well, not just "appeared", since I can't find them anywhere on my machine right now.

I've been using Sync for years and when I finally managed to connect (because apparently the password I had been using was wrong ? But did FF tell me ? No ...), I discovered nothing had been saved. Ever.

A really nice morning.

Hi All,

I keep Google messages for web open in a tab.

Normally I see new messages have arrived because the tab title changes to indicate this.

This feature stopped working a few days ago. I now have to keep switching to that tab to see if there are any new messages.

The equivalent for outlook is still working ok.

Any ideas?

Many thanks

I run a local web server from my desktop PC. As the person running it, I access it only from my desktop PC, and only my account has a password. (All other accounts must be created by me, and have very limited access.) When I log in, Firefox whinges that it's not running on https, which is not my fault, as I didn't write this server. I cannot change servers. How can I prevent Firefox whinging about my lack of a secure (despite being local only) connection?

I cannot access my hotmail on Firefox anymore. It is just a blank white page "outlook.live.com/mail/0/" is what the tab shows up as. I have cleared cache/cookies and such, it has done nothing. Any help would be appreciated. Thanks

Hello, my WIN 10 Drive got busted, meaning I can not boot with it anymore. However, with an other WIN10 drive I still can access the data. I need to save all the Firefox bookmarks before I will format the Drive and install a fresh WIN10. All the searches just tell how to backup when Firefox is open or Win is running: Press WIN Key... etc. None of them is applicable. I have I have bookmarks saved as bookmarks as well as I have a lot on the upper bar. I need them all.

Please teach me how I can back them up and restore on a fresh Firefox. In previous crashes I lost a lot of bookmarks already. ' Thank you.

No matter what I try, I can't allow any sites to present my screen or a window, I can't find an option in settings neither in the option to allow in the tab. The "allow" button is simply not available at all. How do I solve that? The problem happens in all sites that I've tried: focusmate, cofocus, discord, google meet, etc

So just as the title says there is an issue with the binance.us web site and the newest version of Firefox. when you try to type a number like 2.50 into any field the decimal disappears and you end up with 50 not 2.50 if you type 250 into the fields you can go back and add the decimal point so the entry is 2.50 but it's very annoying to have to do this every time.. the previous version of Firefox and all other prior versions did not have this issue

Apps Firefox and Thunderbird are having problems opening links to webpages. In particular, Cloudflare cannot verify (it just cycles between a checkbox "Are you human?" and a browser check) when I use FF.

I use Win11 with NordVPN, but this wasn't a problem before the latest Win11 update. (It also seems to have affected TB reconnecting to Ymail.) I'm now using Chromium to read my Ymail avoid Cloudflare verification, but I'd rather keep using FF and TB apps.

I've been going though Cloudflare, NordVPN and Mozilla online help for a few days now, and I think I've tried everything there.

Thoughts?

I use userChrome.css and userContent.css to (1) turn unvisited links bright red, and (2) turn visited links bright purple, and (3) add underlines to all links.

This works well on light backgrounds, makes links easy to see and easy to distinguish from other text, but makes them harder to see on pages with dark backgrounds.

Is there a way to vary the link color to improve contrast? I can't use the default colors because most sites use blue links which are hard to distinguish from black text.
