Firefox Support Forum

As of today every time I open a FF window it has a sidebar for history. I do not store history and need to stop this. I do not want to close it i want to disable this annoying new function or I need to delete FF and choose a different browser.

I get this message from Gmail when I try to print or open in a new tab.

"Grrr! A popup blocker may be preventing the application from opening the page. If you have a popup blocker, try disabling it to open the window."

I can not find a way to fix this and did not have this problem with the previous version.

hello... im 28 years old and safesearch is on, on my firefox and i actually cant change setting.... it wont give me access to the setting menu. need help with fixing it. account is: farzadmb74@gmail.com

every time whe I download a rar file it is opened with winrar even the setting for the rar file extension is set to save and not open the file. Also some about:config settings I learned from some forums on the web do not help. I think this missbehaviour took place in the past after updating FF but I cannot remember which update it was. How can I configure FF to not open downloaded rar files with winrar (I want FF only to save the file)?

I maintain a website that I update on a regular basis. For the past month, none of the updates have shown up in Firefox. I've refreshed the page, cleared the cache, logged out and logged back in. Nothing has helped. With other browsers, there's no problem -- Chrome, Opera and Safari all show the website updates as soon as I post them. I'm using Firefox 122.0.1 (64-bit) on MacOS Sonoma 14.2.1 (MacBook Pro 14-inch 2023). The website uses WordPress, hosted by DreamHost. I have two other WordPress websites, both hosted by WordPress, and Firefox is showing updates with no problem. I'm querying DreamHost on this as well, but I suspect they'll must say it's a Firefox problem.

I have just discovered Pocket now allows you to sort Pocket Saves into Lists. !! Hurrah and thank you so much.

However, it would be SO HELPFUL if it was possible to sort the Lists alphabetically, as I now have so many it is difficult to find a particular List.

I realise this may be a development, but just thought I would check.

Also - I am not sure many people have realised you have added this ability to Pocket, so maybe you could advertise it more. I beleive a lot of people would prefer to use Firefox for saving Collections instead of other providers, but it was so confusing to use it before you added this capability. Thank you

Hello, sometimes firefox seems like it is working fine, other times certain sites like youtube, duckduckgo and spotify will not load, while others will.

I've gone through and done everything the help articles suggest, nothing happens - then a few days later everything's fine. It's gone on like this for a few months. Any help would be greatly appreciated.

thanks -alex

I have spent hundreds of hours over the years trying to figure out how to hell to suggest words to the default firefox dictionaries. I don't mean weird words, words used constantly in scientific settings. It is infuriating. I am willing to take on this task if no one else is. How do I join the effort?!? I have 20 years experience at a fortune 500 company. Google is worthless these days.

I'm still running Firefox under Windows 7. I've now connected a new monitor with a resolution of 2660 x 1080 using an HDMI cable (previously DVI), and since then I've had major problems setting up websites. the websites are only partially built and I have to reload several times. Can you help me?

A few days ago I accidentally deleted my browsing history and I have lost some pages that I need to revisit, is there a way to get the browsing history back as of 12/20/2023

Windows 10 Pro v 22H2 Firefox 121.0.1 (64-bit)

I have tried preventing Firefox from autostarting with Windows start up by examining these potential program starting locations:

Firefox-Settings-General: "Open Firefox automatically when your computer starts up": Option not available about:config - toolkit.winRegisterApplicationRestart - set to "false" No listing for Mozilla or Firefox in Windows 10 "Startup Apps" settings page No listing for Mozilla or Firefox in Windows 10 msconfig.exe/System Configuration-Startup No listing for Firefox in Windows 10 Task Scheduler No Firefox program in Windows 10 - %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder All Firefox extensions (2) are disabled

Where else should I be looking? Thank you

I am a startup founder. I'm making a webgl rendering engine. I'm doing a stress test with 4 large paragraphs amounting to tens of millions of triangles on a macbook air. Firefox is on the latest version.

When I run the app in chrome/safari/opera, the performance is normal. ~45fps. But in Firefox, it's very slow. My FPS counter (in a requestAnimationFrame loop) says ~45fps on all browsers. But in Firefox, even though the counter says that, the real frame rate is ~3-5fps.

When I try to profile, the problem magically goes away and we're back to ~45fps. I played around with profiler settings, and the key determinant is whether or not I'm taking screenshots. No screenshots = slow. Screenshots = fast.

In the flame graph, in slow mode (no screenshots), it seems like I get stuck in the canvasRenderer and the Renderer mostly waits for it. But in fast mode (with screenshots), the canvasRenderer keeps up and the Renderer spents most it's time in: iokit_user_client_trap

I'm not sure what to do. This is only a problem on Firefox. There's some sort of gpu/threads/something that switches when I profile with screenshots that makes it way faster. This performance hit basically ruins my app for Firefox only. Any idea what I should do?
