Firefox Community Forum

I have various sites that won't accept site login credentials but work on other browsers and Firefox is running very slow. If I completely shut down and restart my computer, the logins will work for a few minutes but then stop working again. I've completely uninstalled Firefox several times, deleted my profile and created a new profile. Ran Firefox in troubleshooting mode with extensions turned off. None of these have had any effect. I recently saw a post that this might be a Firefox issue with version 154.00. I'm currently running version 154.01. Is this actually a Firefox issue or do I need to continue to look further into my computer and router for the problem?

For the past few days when trying to use Google search on Firefox I get this message:

"Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?"

Then it makes me jump through several hoops to do a search on google.

This is a Firefox specific message as I can switch to Safari and there is no roadblock.

Is this happening to anyone else?

Any way to resolve?

Why this is a Firefox issue and not other browsers?

For the past two days I haven't been able to get past the recaptcha on several sites (Facebook, Instagram). I have tried all the workarounds other users have provided and what Google has offerd to no avail. I'm also having a difficult time accessing my hotmail acct from Firefox as well. I don't seem to have this issue with either of these problems if I move to a different browser. Firefox has always been my main (and only) browser, yet more and more often I seem to have issues anymore. What the F is going on? Would appreciate any help I can get. Again, I've tried removing Ad Blockers from these sites and even turned off the 'Enhanced Tracking' thing on the address bar; none of this works.

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 want to be able to make voice and video calls via facebook messenger using my PC camera and microphone but, the message I get is that "voice and video are not supported on this browser (Firefox/Mozilla) . It is supported on other browsers. I really don't want to switch browsers, I love firefox. I did find a couple possible fixes via advanced WebRTC settings but everything seems fine, i.e. it is clicked on true not false. I need this soon, can we get settings changed?

This has worked fine in the past, and works now in Chrome, but not Firefox. URL is https://outlook.cloud.microsoft/mail/?bO=1&msalAuthRedirect=true&sessionId=20fbbbb0-2fa6-4848-8fec-c20c6d3a8be4

Here's the error message

Looks like there’s a problem with this site

Firefox can’t connect to the server at dlhd.pk

No such problem on Edge !!!

Check https://piunikaweb.com/2026/08/14/firefox-x-images-videos-not-loading/ for details, but basically xTwitter/Melon messed again with their latest update.

Any word from those in the know yet? Having to use different browsers to see multi-pic posts is really annoying.

Google Maps displays black map tiles in Firefox, while it works normally in other browsers. The issue persists after disabling extensions, testing Troubleshoot Mode, clearing the graphics cache, resetting graphics preferences, and testing a new Firefox profile. Firefox version: [version]. Operating system: [OS]. Compositor: [value]. WebGL Renderer: [value].

I know I'm probably not in the right platform to be requesting a feature, but I hope you can add support for this website because I can't do video calls on facebook through firefox and I have to use a different browser to do so. Please add this feature as soon as possible. Thanks!

Chase Banking worked for years using FFox on Win10 PC. and using verification with Message on phone. Now is asking for secondary verification using a phone app that I dont have and cannot load. Can login thru Microsoft Edge and Googal Chrome successfully using PC. Not Happy!

I have used Facebook in my Firefox browser for several years. Then all of a sudden, Facebook will load, then it will not load and yesterday and today, it won't load at all. I have to go over to Chrome to get on my Facebook. Please fix whatever is preventing me from using Facebook on Firefox.

my yahoo emails have all gone blank--the From: Mary and To: Frank in the top left of message box remains, but the entire message itself is completely blank. however, the messages show up as usual in safari. any help or suggestions would be welcome as i cannot reach any support from firefox. thank you.

I have had problems logging into my PayPal account have changed my password several times but the change has not been saved. also I have tried to purchase items on the internet and paypal would not connect in firefox but would connect on another server why ?

In Firefox, a lot of my pages are not loading at all...the tab just shows that the website page is loading but it never does. The menus of the website will appear, but pages are not loading. This is not happening in MS Edge. I prefer Firefox, but lately have had to go to MS Edge to load pages. What could be happening?

Hello -

I cannot correct misspelled words when using Proton Mail. It has worked in the past, until recently. Perhaps the latest Mozzilla update? In the body of my email Proton email shows the words which are misspelled but I cannot right click to correct the spelling. Proton never seemed to support the "subject" field typos but did support spelling correction in the body of the email. The spelling correction works properly in Google docs.

Spelling correction is turn on in Firefox settings.

- Firefox 151.0.3 (aarch64)

- iOS Tahoe 26.2
