Hi! I switched to Firefox some years ago for a lot of purposes. Firstly I wanted a secure browser and a browser which help me in web devopment. Currently I use Firefox Developer Edition on my pc, but I'm writing this message by my mobile phone. I want to represent Firefox with some stickers can I have one to decorate my laptop? Thanks a lot for every thing.

After a update my browser was running very slow, I'm not sure what I did but my whole browser, including history and bookmarks and add ons reverted back years. But I have a whole folder of Old Firefox Data which is from today.

How do I get this back on there and get everything back to normal?

I'm having an issue that seems to Lock up YouTube on Firefox.

I'm trying to get back into using Firefox but I'm having a persistent issue in both FF Mainline and even in FF Beta 119.

If i play a Video on YT then switch tab to do something else then go back to YT it lock up the video window. I do not have this happen on Chrome or Edge.

I have tried refreshing the browser and still have this issue.

The "font family" property does not change the font of the "option" tag if the font is not installed locally on the computer. I am using Firefox Developer 118 (0b9). Are there any solutions to the problem?

After updated to Beta v118. no sound. V118 uses FDLIBM. Android 7 device. After 0b1,0b2,0b3 sound still not working

does user has to install FDlibm themself? and how?

I switched to Firefox DE because I wasn't able to install 3rd party extensions. Just now, my middle click isn't working. I can't use the middle click to open/close tabs and to open links in a new tab. I checked my settings, tried a new profile, nothing works except in normal Firefox, the middle mouse does work, but I don't want to switch to that. My middle click also works in Edge and other apps, but please fix this issue as soon as possible. Thank you.

PS. Please add biometrics to Firefox, like how Google did with Chrome.

I am developing a website (using AstroJS, but i don't think that's the problem) and since yesterday I am experiencing issues when opening devtools. Once I open devtools the whole FF tab becomes unresponsive, I cannot even refresh the page until they are done loading. I can change devtool tabs from 'inspector' to 'console' to 'network' etc but especially 'network' and 'debug' tabs are blank.

I run a 'performance' capture and got these results. In the test I have only opened the devtools and switched to the inspector tab which is unresponsive. The CPU usage is at around 90% however, I don't really know how to read the finding and understand what the problem is.

So anyone that can help me understand what is going on here?

My Firefox has got inconsistently large font size in some UI, namely on the homepage (text elements with style "font: caption") and texts in the Update Firefox notice box (which I don't know how to reproduce within a resonable time and effort). It just happened after a ordinary restart of Firefox: no updates etc. I tried updating Firefox after that but to no avail. How can I fix it?

Even though Recently Visited is turned off I have lots and lots of recently visited sites showing up on my homepage. I have to manually remove them to clear the homepage. How do I make it stop showing all this clutter?

It happens on both me and my girlfriends phones, so I guess either something is wrong with the setting or it doesn't do what I think it is supposed to do.

See screenshots for example.

I'd like both my devices to be safer for one I don't want to use Chrome and I can't seem to get Chrome to stop or get off my devices not sure how to do that I like to have Gmail and using the Gmail app is fine with me but it seems that my mail keep going to different places I don't know how to stop that and I tried to read everything that is in the stuff that I'm downloading but it seems that I am still downloading stuff that is way out of my league and I'm not trying to make anybody mad and I don't want to be judged for my p*** I've been trying to read how can I ensure that I'm the only one looking at the stuff I'm looking at

I ve two problems

1) recently i can't play videos on websites, checked i ve most updated app & no adds on & cleared my cache but the problem standstill

2) logging in some applications may require redirection to their site , despite i ve Firefox as my default browser those apps are using chrome instead of Firefox recently

On some sites like youtube, crunchryroll, and other sites usually where it's main purpose is to play videos my sound plays fine. However, on other sites like osu's website, chess.com, duolingo, and others, there's no sound at all. I've tried refreshing, restarting, running in safe mode, and even reinstalling the browser but none of it has worked. My tabs are also not muted. Does anyone know how to fix this?

I'm on Firefox Developer Edition 119.0b9 (32-bit) and Windows 11 Pro 22H2 but I've been experiencing this problem a lot longer ago even before upgrading to Windows 11. The first thing I open in my computer is Firefox, it gets the window itself quickly but the page stays blank with the gray loading dot going right and left for nearly 10 minutes before the page loads and Firefox works normally. I don't experience any issues while browsing the internet after that long loading but it's really annoying especially when I'm in a hurry and I don't have 10 minutes to stare at a blank page.

I just updated to Firefox 120, and tried the new GPC setting (Tell websites not to sell or share my data). I ran into a problem when I went to the Xfinity community forums (https://forums.xfinity.com/) . It causes a banner on top showing they recognize the setting. There is an "X" in the corner, and some text that says "Hide this banner", but they are not active. Plus, I cannot make a new post or do a general reply (that weird forum software has both local replies to a particular post and general replies to the general thread.)

Is this a bug in Firefox, or a bug in their forum software? I attached a picture of the message it gives.

I'm new to Firefox, usually in other browser, like Chrome and Edge, when I use the selector to choose element and click on it, it will bring back the console but it doesn't seems to happen in Firefox. ( I'm using separate window for the console )

I have used Firefox on many systems - MacOS, Linux, Winblows and mainly Android Cellphone.

"about:config" on a Cellphone has never worked, never worked consistently, or mainly been confused with Desktop Firefox :P

Hello?!? The future is mobile not stationary desktops  :P But I digress. Please dont misunderstand me - I love FF - but when I want "about:config" on A Cellphone - I WANT IT to actually work on a freaking cellphone  :P

Is the software config too much for International Mozilla to understand? Or has Mozilla had way to much input from everyone on the planet thus watering down an otherwise great browser?

Kind of rhetorical - I know it will never be fixed in favor of locking in a dieing desktop setup  :P

Every time I close the ff and enter other app and come back to firefox or just lock the screen all pages refreshes in firefox, power savings for firefox are disabled. It doesn't happen on chromium browsers
