Firefox Community Forum

I have cleared all logins and ALL browser cache and cookies, checked for updated version (running 155.0.1 for Mac OS) and restarted the browser. But still get a BAD REQUEST error when trying to access someone's Calendly page. I can load the main website of Calendly, but it will not load specific person's calendar.

I tested this in Chrome and in Safari and there are no issues loading someone's Calendly page. Here is an example account. https://calendly.com/rickcoughlin

I have also tried this in Private Mode. Can someone help?

I use the link provided in firefox help. It provides a window with a link to download a new version. but I click on the link, get an update window. I click on the download now and the download doesn't happen. It just sits there showing 0 bytes downloaded. How to update?

I have noticed several automatic updates in the last several days.

Yesterday, I started my Lenovo laptop and clicked on Firefox to start my business day. Clicked on the icon. Nothing opened on my screen. Each time I clicked, a thumbnail would open (see attached image).

I can right click on the icon. I tried open a new window. Nothing. I tried open private browser. Icon opened, I can see thumbnail, but it did not open either.

I tried to download new Firefox. Same. I tried to delete Firefox from Installed Apps in settings. Then I was asked if I wanted to Refresh Firefox instead of deleting. It saved my Firefox files. Thank you. I followed the steps. Firefox worked throughout the day.

This morning I tried to open Firefox...nothing except thumbnails like in the photo.

Photo has version date for Firefox. Dated yesterday 9.9.2026.

Appreciate your help.

All I have access to is right click on Firefox icon in my tray. I cannot see any settings.

When accessing the main search page my android phone is briefly loading an image of the Firefox logo that is all purple. It then starts loading the main search page. When I try to open a pinned site it is very slow and times out frequently. I'm concerned that I have a virus.

latest update seems to have broken firefox 155.0.1. It opens but then becomes unresponsive. Two different PC, both win 10. How can I revert to previous?

I can not get extra info from troubleshooting page cause FF won't open so as to be used.

سلام. من میخواهم بدانم چطور باید در فایرفاکس مسدود کننده تبلیغات را تنظیم کنم. آیا اصلا راهی وجود دارد؟ به وب سایتی رفتم که گفته مسدود کننده تبلیغات من روشن است و با آن نمیتواند اجرا شود. لطفا کمک کنید تا بتوانم آن را خاموش کنم. با تشکر

Alors que je n’ai pas demandé de mise à jour une nouvelle page Firefox est apparu sur mon ordinateur, iMac Apple et tous les marque-pages personnelles et autres ont disparu, Que faire pour opérer la totalité de mon ancienne version dans ce nouveau navigateur,

Hello,

I am experiencing a serious display flickering/refresh issue in Firefox when opening DRM streaming websites such as Netflix, Amazon Prime Video and HBO/Max.

My system:

GPU: NVIDIA GeForce RTX 3080 Monitor: LG 34GL750 Windows PC Latest NVIDIA driver installed

The problem:

When I open Netflix/Prime Video/HBO/Max in Firefox, the display repeatedly flickers or appears to restart. There is no "No Signal" message from the monitor. Closing Firefox sometimes makes the display recover. Unplugging/reconnecting the display cable has sometimes been necessary. The same problem does NOT occur in Brave, using the same PC, GPU, monitor and cable.

Troubleshooting already performed:

Updated to the latest NVIDIA driver, including the recent driver update that mentioned display-related issues. Tried a different display cable. Disabled Firefox hardware acceleration. Tested with Firefox Troubleshooting Mode — the problem still occurs. Disabled/enabled Firefox DRM/Widevine — the problem still occurs. Tested with a completely new Firefox profile — the problem still occurs. Disabled G-SYNC — the problem still occurs. Disabled uBlock — the problem still occurs. Checked about — there are no recent crash reports related to the problem.

Firefox about information:

GPU #1: NVIDIA GeForce RTX 3080 Active: Yes

In my normal Firefox profile: Compositing: WebRender (Software) HARDWARE_VIDEO_DECODING: runtime: unavailable Requires texture sharing Blocklisted; failure code FEATURE_FAILURE_BROKEN_TEXTURE_SHARING

In a completely new Firefox profile: HARDWARE_VIDEO_DECODING: default: available

However, the display problem still occurs in the new profile.

Thank you.

Warum muss ich immer wieder die Surfdaten löschen damit ich die Seite meines Routers öffnen kann ? Nur dann funktioniert eigenartiger Weise mein Passwort. Es ist die Seite:http://192.168.8.1/#/home zu meinem Huawei B636 Anmeldung. Mein Firefox ist auf aktuellem Stand. Bitte um Info bzw. Abhilfe
