How do you avoid/deal with Firefox website incompatibilities? This happened on consecutive visits to two different websites today before I posted here.

In the first one, I disabled Ublock, cleared cache and cookies, and the site loaded, I then enabled Ublock with no error prompted.

Then I got a tab crash on Youtube. I wouldn't call tab crashes a daily occurrence for me, but I'm accustomed to them

Gmail tab crash just now. It just happened now with another website tab crash. i'm reverting back to 147.01

Is there any way to get the root of this. The only recent changes I can think of are browser (147.0.2 yesterday) and addon updates. Should I post my list of addons?

I have my nonprofit's website through Weebly...but recently I cannot get it to come up when I type in the address...I get an error that says PR End of File Error. I am able to access the website through Edge...but I hate Edge!!!!

But it makes me think there is a setting through Weebly that is making Firefox not show the site.

Any help or advice would be great appreciated.

When I search Google Images in Firefox, this pops up. I tried using an extension to hide it, but I can't see the rest of the image, which is inconvenient. Microsoft Edge and Google Chrome load it, so it's not an issue. Is this a Firefox feature? It's a hassle to disable the extension just to read the rest. Could you please give me some advice?

I use default browser and suddenly Firefox can't load website Shopee Try chrome and it load shopee normal. Have try turn off all extension for shopee site. Hope someone can help

Since 2 hours ago the following site has stopped working correctly in Firefox. It was loading normally in the morning(3+ hours ago) but now it does not load any maps etc. It's a weather satellite site. The site is: https://www.wetteronline.de/wetterradar?wrm=7&wrx=38.19,25.97&wrp=periodCurrentHighRes&wrf=true

It works normally in Chrome, and Opera and Edge. But not in Firefox(I have the latest update). I have cleared cache for this, I have tried everything but it does not load the maps.

Does it work for you?

In the screenshots I show the normal loading in Chrome and what it does in Firefox.

I'm using the latest Firefox. All of a sudden as of this morning, Firefox cannot not load Facebook or Twitter. I can open YouTube and YouTube videos appear but will not play (just a spinning wheel when I try to play). The Amazon landing page is scrambled with code. (see image attached)

I use Ghostery ad blocker but the issue persists when Ghostery is paused. I can use Safari without issue. Can anyone offer any insights?

When I have attempted to log in to my MyPoints and my Entergy electricity account to pay my bill. I can not log in after the previous update. I was able to log in to my Entergy account on 08/22/2025 to pay one of our power bills. This was accomplished with out issue. When I went to log in to my Entergy account on 08/29/2025. The User name and password screen cleared correctly. The next step was for a 2ed step verification with a 6 digit code sent to my cell phone. This did not work at all. I tried several times after restarting my phone , computer, phone and computer with the same result.

Firefox for Linux can never get past Cloudflare's security captcha. Not just the latest version, but several versions in a row. The page reloads over and over again. Eventually, I launch a different Chromium-based browser and open the page there. Firefox for Android usually handles this issue.

Facebook Games - I get this: "Sorry, your browser does not support this feature. Please use a different browser and try again. " What do I do? - 10/20/2025

Starting the month of February 2026, I cannot get into the following websites anymore to do my on-line shopping. Walmart.com and King Sooper grocery store (Kroeger). I get messages to try again later all the time. If I use another browser such as Edge or Chrome, I can get in no problem. Not sure what is going on??? I chatted with Customer Service Reps at both sites, they don't know why I cannot get in with Firefox, unless some of your security certificates have expired. Help!! - Stan

I typically use Firefox every month to access my Xfinity and Verizon accounts to download my billing statements for expense reports. I have noticed recently that Firefox will not show the complete website for Xfinity.com, where I can see my billing statement (after login), but if I copy/paste the link to Chrome, it shows the complete site and billing statement immediately. Is there an option to restore functionality to Firefox?

Thank you

When opening links via Firefox that are associated with the National Association of REALTORS (NAR) website, I keep getting a message on their homepage screen that says, "An Error Has Occurred. An Error Occurred in Client", and I can't go any farther. There's no explanation or "pop-up blocked" notification, just that message. I can open the links in the NAR website via Chrome, but not Firefox. I talked to tech support for the NAR website, but they said they're not familiar with this complaint and said to try opening on Chrome, which I successfully was able to open the link there. Please help as I don't want to switch to Chrome. Is there something in Firefox not allowing it to open? I'm not even sure which topic this falls under, so I picked Accessibility. If it belongs under another topic, please transfer to that dept. Thank you! Annette Karnes

I can't log into my doctor. Their web support says to not use Firefox.

I've been with Firefox for years. I don't want to change browsers.

Can you fix the communication problem between Firefox and MyChart?

Thanks for everything,

I need my gmail account but I cannot sign into it, it wants me to start a new one, but that will not do at all. I will wait for a week to see if you can rectify this problem.

Recently, I wanted to look up a car on CarGurus.com. I have used this site repeatedly with Firefox but it gave me "Cannot Access Website" error. I am an IT Tech and did a Cache Purge, then a deinstall-reinstall, and finally a Total and Complete Deinstall down to Registry level. No Help!!! Then someone responded on here saying they had the same problem. When I went to check, I was able to connect. Today, Same Thing!!! Chrome works, Firefox does not, so here I am writing again about an Issue I believe is a Firefox Issue. You need to look into this Folks!!!

Hello,

I’m experiencing an issue where I cannot use ChatGPT-5 in Firefox. When I log in and try to select or use GPT-5, nothing loads or functions properly. Other models like GPT-3.5 work normally, but GPT-5 does not respond.

I’ve already tried refreshing the page, clearing cache and cookies, and even disabling extensions — but the problem persists. Could this be a compatibility issue with Firefox? Any advice or support would be appreciated.

Thank you in advance for your help!
