I get so choppy scrolling that my eyes hurt after few minutes. Doesn't happen on Chrome or Edge. It is most noticable on YouTube. It feels like it's running at 15fps

I have noticed issues with; when I download an attachment, i.e.graphics file, that the browser closes.

I have my emails configured where Yahoo and gmail available by selecting. Sometimes Yahoo mail will close and Gmail will remain open, Firefox doesn't crash but somehow closes either gmail or yahoo but not both???

When I try to log in to any Google "Ecosystem" (i.e Gmail, Youtube etc.) I see it (check screenshot below). I'll use Firefox Developer Edition. In vanilla Firefox and other browsers, everything works as usual.

I am pasting this video link first to show exactly is happening when I use Google Images Search results. https://youtu.be/HD-GPkORQPA

This happened suddenly. Everything was fine when I last used google image results, I was playing a game and when I alt+tabbed to search for something, this was happening. I have no idea what could have caused it since I didn't install any new extensions, CSS styles, programs in my PC nor any big changes that would give me an idea of where to start.

I already tried disabling all the extension and that didn't help at all. The only way I've managed to make this stop, was when I opened a private window. There the image search results were fine and I could zoom in, and out and no weird scrollbar issues were happening.

I went back to a normal window in Firefox, and noticed that if I log out from my Google account, this will also fix the issue. And when I logged back in, the issue was happening again.

Anyone have any idea why this would happen, and how I can fix it? Thank you!

Sometimes when I open a video it doesn't play, it infinite loads with a black screen and I tested it on a separate browser and the video works there

I've tried deleting cache and cookies but it doesn't work

Today, web pages started showing small numbered boxes behind each element on a webpage. As you move down the page, the numbers are in sequence. I tried the font settings. They are all set at what they should be. I also tried the config settings, no joy. If I restart in troubleshooting mode, the boxes go away. Note: I am using Linux Mint, and Firefox just updated yesterday to V103.0.2. Any help would be appreciated.

Hi, all websites that have embedded tweets stopped working for me today. I simply see a box that says Loading tweet...

I have attached an image that shows the error. When I am in troubleshooting mode the error goes away and tweets load. the problem is i cant figure out why. Even when i disable all extensions and turn of troubleshooting the tweets stop loading again.

Dear Admin,

My firefox browser can't shown the correct myanmar unicode script when I type in google page and other websites also shown the wrongly font scripts that are unable to read. I'd asked to google and they said it is the font rendering problem and advice ask to your team for help. Please take a look and advice me how to fix it. I'd installed myanmar unicode font in browser and set as default. Other websites which are use Myanmar unicode are also shown the wrong script in firefox browser. The browser version is 103.0.1(64bit).

Thanks for your kind response, Htet Aung

Using Firefox 103.0 on a Mac running Monterey. Since updating to FF 100.0 or possibly 101.0, the BBC News website's videos won't play. I've tried turniing off all privacy/security add-ons and settings but still nothing. Just a grey rectangle with the BBC logo in it (see screenshot).

Safari can play them though. Any ideas?

When using built in search (google default) -- browser stops responding. Shows Firefox new tab background when loading the search. Issue resolves on Firefox close and re-open. Paste and go, creating new tabs also fail with same 'new tab background' displayed. Issue is intermittent but appears often, at least 4-5 times a day.

Tested same sample search with google chrome in same time period, no issue.

Issue appeared around the V99 update. Fix would be greatly appreciated - exiting and re-opening browser, dropping all tabs to reload is a serious usability issue.

At some moment I´ve got a pretty big sessionstore file (6,6 Mb) which does not load properly. I´ve tried a few of FF versions and settings. My current version 103.0.1 64 bit loads it for few minutes and crashes when tabs appear. Some older versions loads it but after that have various problems with program interface: new tabs sometimes won´t open, no float tips when I´m hove cursor over tab header and so on. Also in such cases browser often crashes and not update old sessionstore file. I have 16 Gb of RAM, FF takes up to 5,5 Gb before tabs appear for moment and FF crashes. I have such big sessionstore file earlier (for example, 24.07.22 it has size of 6,5 Mb), but all worked fine. Maybe there are any internal setting that I have to try?

It periodically blinks and that breaks buttons that open menus and closes context menus from Firefox. Also disables some keys, the tested list is arrows, might need to test that on all. As it's version-independent, it might be a dependency issue. It also happens in safe mode, which is saddening.

When using Google Sheets in Firefox, it's impossible to access the Sheets menu shortcuts (e.g. typing Alt+D+R+S to open the advanced sorting dialog) because Firefox captures the Alt keystroke and doesn't pass it to the web app.

Of course, Chrome passes the Alt keystroke to Sheets just fine so the keyboard shortcuts work as expected. But I don't want to use Chrome or any other Chromium browsers. Has anyone found a workaround to this issue? (Hint: don't say use chrome)

When I open Firefox with a dozen tabs showing, Task Manager typically shows Firefox to be using 1.3% CPU, 715 MB Memory and 0.1 MB/s Disk. However, as soon as I open www.walmart.com in a new tab, Firefox CPU goes up to between 34% to 52%, Memory to 13,900 MB and Disk to 50 to 200 MB/s. If I reboot, it is repeatable. I have an AMD Ryzen 5 3600 with 16 GB. What's going on?

Hi! Yesterday i updated my firefox to last version and i got my UI way too big, so today i looked online for some fix on that. I found a fix saying if you add a line in about:config site with the parameter "ui.textScaleFactor" with a value of 100 it will be fixed. but by mistake i changed it to 10 insted of 100 so when i open firefox i have a super big black screen

most of my problems are i can't reinstall firefox because it made the same weird big ui problem. There is any way to fix it?

thanks in advance

Every time Firefox updates itself, all of the text and images and page layouts become huge. I have tried every single fix that is usually suggested for this issue:

Zoom out with scroll wheel: Makes text smaller (and images, if I disable zoom text only) but does not fix page layouts (ex. Google search still has a horizontal scroll bar, even in full screen.)

layout.css.devPixelsPerPx: No effect at all. Can be made bigger at values over 1.0, but not smaller.

Compact mode: Sizes down the toolbar, but nothing in the webpages themselves.

Refresh Firefox: Still huge.

Safe Mode: Still huge.

Disabled all extensions: Still huge.

Complete uninstall with all leftover system files removed with RevoUninstaller, then reinstall: Still huge.

Other browsers: Display correctly. Absolutely no issues with size, including Firefox forks like Librewolf. (See attached image for direct comparison between the two browsers.)

I can temporarily alleviate the issue by using a restore point on my computer from about a week ago but when I opened Firefox this morning, it bumped me to an update page, and everything was huge again.

I was previously using a non-native screen resolution while I was recovering from surgery in bed and the screen was too far to see at 1920x1080. But I did not have this problem for two months of recovery. It started just a couple days ago. Returning the screen to its native resolution has not resolved the issue. Firefox, and only Firefox, is still enormous.

Firefox has worked fine on my WinX systems for years. Yesterday it downloaded a new version (103.0 64-bit) that totally destroyed the experience!

Everything I see now is GIANT SIZED compared to the rest of my desktop and to the old Firefox. I've looked for any relevant setting and I've tried the "Refresh" button with no help.

I want to go back to the previous version!

I don;t know if I chose the right "best describes the question" because the first half of the option is off the screen to the left, and there's no way to scroll over. I would like to go back to the version that preceded this latest update please. It worked well. Please reply by email, [email-removed], because I can't read most of what's on the screen here. I hope someone pays attention to this, because otherwise I'll have to abandon Firefox, and it's been by far my preferred browser. Can't think what you've done to it. Your updates in the past all worked fine. I'm on a Lenovo ThinkPad S145 with Windows10.

I have Firefox 100.0.1 on my Mac desktop, and Firefox 100.0 on my MacBook Pro laptop. I can no longer access my Microsoft OneDrive account via the web on my desktop, but I still can do so on my laptop. I have gone through your posted troubleshooting steps for Firefox on my desktop, to no avail. How do I get my desktop back to version 100.0 so it will work again? I can access my OneDrive account via the web on my desktop when I use the Safari browser, so the issue is definitely with Firefox version 100.0.1, and not with my desktop.
