Firefox Community Forum

Hi,

I’m facing an issue with my website’s fine checking tool on Mozilla Firefox. My website is evgfinescheck.com , and the tool works fine in some browsers, but on Firefox it doesn’t load properly and sometimes shows an error.

I am already using the latest (updated) version of Firefox, so the issue is not due to an outdated browser. The tool either fails to fetch data or doesn’t respond as expected when users try to check fines.

I’ve checked basic things like internet connection and browser updates, but the problem still persists specifically on Firefox.

Can anyone guide me on:

What could be causing this compatibility issue? Are there any common JavaScript, API, or CORS-related problems specific to Firefox? How can I debug or fix this issue?

Any help would be appreciated. Thanks!

Firefox version 152.0 : Firefox is continuously refreshing the page on a particular Website, in both Windows11 and Linux versions, making the site unusable ( unable to click anything ). The website loaded ok previously using Firefox and still loads ok using Chrome. Disabling extensions doesn't help, neither does deleting the cache and cookies. What changed and why? Is there anything else to try?

Recently, I've been having a problem with signing in to things via my Google account – the problem being that I can't.

Whenever I click on the "sign in with Google", it redirects me to the "accounts.google.com" page, prompting me to choose my account, but once I do, I get redirected to "accounts.google.com/gsi/transform", which is just a blank page with nothing in it (see image attached).

I know this is not a problem with Google, as I have no problem signing in anywhere else.

This happened to me once before, but the reason was one of my extensions, which for some reason interfered with the sign in; however, this time this solution does not work. I tried disabling every single one of my extensions, turning all kinds of protections in the settings on and off, deleting all cache for all relevant sites, but to no avail.

I of course also tried looking this problem up on the internet, but whenever I found someone with this problem, the solution that worked for them was always just disabling an extension.

Thank you for any answer.

I use Firefox 150.0. Flightradar24.com reports that my browser doesn't support WEbGL2. However it reports that Firefox supports WebGL2 since version 51.

the home page for AOL has an image of a current event or news worthy item, until yesterday there has always been a description or statement explaining the image to the left, that screen is now blank. I had my computer security team check my unit and they say the problem is with Firefox and I should use a different browser.Also under the new email tab there was an old mail tab, that is also gone as of yesterday. Are these problems in fact a Firefox issue?

Hello,

I am reporting a performance issue specifically related to Google Search's AI features (AI Overviews) in Firefox 149.0.2 on macOS.

The Issue: When an AI-generated summary appears in Google Search results, GPU usage spikes significantly, reaching up to 212%. This causes the laptop to overheat and triggers high fan speeds.

Critical Comparison:

Firefox 149.0.2: Extreme GPU load and performance degradation when rendering Google AI elements.

Google Chrome 147.0.7727.56: Works perfectly with normal GPU usage under the same conditions.

Tested on two different MacBooks: MacBook Pro (A1502), 16GB RAM, i7 (2015) — OS: macOS Monterey. MacBook Pro (MMQX3), 64GB RAM, M1 Max (2021) — OS: macOS Sequoia (15.x/Tahoe).

Running Firefox 149.0.2 (64-bit) on MacBook Pro (16-inch, 2019) with Catalina (10.15.9).

I was in the process of updating a non-profit's website and had opened the html file on my computer. I noticed that the "y" (lower case) was missing from the days of the week. I checked the RUNNING website and saw the same thing. Checked he same website with Safari and the "y" suddenly appeared. Okay, so I then tried to add another "y" somewhere else on that page and ... nothing, so on a whim I added a "Y" to my Mac's file and guess what? It upper case Y displayed. Also noticed that on some web pages instead of showing me the characters in some words, it substitutes "ddddddd" for some words. What's up?

certain sites ( like FedEx tracking ) say that I can't visit because my browser needs an update. but I checked and Mozilla says that I AM up to date . last update April 28 What can I do to fix this?

No accurate topic in the ddlb, so picked this.

I've bought from an ecommerce site for years, using FF as my browser. Suddenly, over the last couple of weeks, I can't get to, receiving a 503 error message.

I can still get to the site on Edge, but I don't wish to use it or Chrome for ecommerce. Either they or you broke something. What needs to be done?

after last update stop working .if I use ctrl v it will paste in. When i try using the mouse it doesn't have paste in the block that pops up.

I can click and paste in the condition box but not the description box.

If I use edge it works. I don't want to use edge

I have also cleared cookies and cache

Starting on June 9 2026 my Rockland Trust banking website will not open also other bank websites not opening or take several minutes to open, also other websites not opening. All these websites opened before June 9 2026. I have done all the recommended steps even uninstalling an reinstalling Firefox. What did Firefox do, as I had made no changes. I can open all these websites on other browsers, Google Chrome, Microsoft Edge, etc. I want to keep using Firefox but I can't if websites won't open. Clare O'Brien

I'm trying to e-file and can't because I'm being told the following: To display this page. Firefox must send information that will repeat any action (such as a search or order confirmation that was performed earlier
